I understand that Adblue got its name after the marketing disaster of the more honest and accurate Golden Showers Additive.
Hahahaha
So if you burn recycled cooking oil and adblue... do you get the unmistakable odour of piss and chips 😕.
👏👏👏👏👏👏👏👏👏👏👏
This just reminded me of the absolute pleasure I experienced the other day. Following a 70s bus/motorhome, running a 2 stroke Detroit Diesel. Not only were my ears blessed with that fabulous music they produce with their straight pipes, but I also got to enjoy the very different smell of purely burnt Diesel fuel, without any of this BS between combustion and release to the surroundings. Bliss!
(as late as 2015 - Aussie output, still suffered the same diesel product..)
Native Detroiter, that was poetic 😊
If it was actually burning the fuel properly you wouldn't have been able to smell anything from the exhaust at all.
@@peglor not to mention they didnt really change the way the diesel is burned, if anything they got better at getting the diesel to ACTUALLY burn which would arguably mean its more "purely burnt", and filtered the garbage it emits out.
bit odd to describe the smell of straight up hardcore carcinogens as "bliss" though, no objections to the sound though, they are pretty sweet. just not to stand near huffing on the exhaust like its a bong.
I loved the music of a Detroit Diesel at full throttle.
As a diesel mechanic in the US i have a different slant on adblue or def fluid as we know it.
The problem.... polution
The solution as you mentioned of 66% de-ionized water and urea (a byproduct of petroleum)
Dispenced in a plastic jug, placed in cardboard boxes stacked on wood pallets wrapped with plastic shrinkwrap.
Placed in diesel trucks and distributed to every ass bleeding retail establishment from the hollars of Appalachia to the desert of Arizona and the Canadian tundra.
Purchase the product and pour the contents in your tank then throw away the bottle, shrink-wrap and cardboard (upon which another truck will take to the landfill)... congratulations you have helped solve pollution!
If you could spell better, I might have paid attention. The illiterate shouldn't share opinions, as opinion is just cranial flatulence.
Great informative video John. As an automotive tech of 35 years +. The changes to comply with Euro emissions standards have even confused me. I'm an Australian based automotive technician. Highly Bosch trained. The general automotive public wouldn't know there is a difference in exhaust after treatment. Dpf. Diesel particulate filter. Deals with the fine soot particles that are produced with normal combustion of the fuel . Due to the high energy density of diesel fuel and the low energy conversion . Incomplete combustion ends in the production of soot. So the Dpf was designed to trap and capture the fine soot particles which will pass through the upper airways of human lungs . As mentioned in your video that primarily captures them in a small furnace to be dealt with later. Such the term. "After treatment". SCR is selective catalyst reduction. The addition of urea in to the exhaust is to combine nox ( oxides of nitrogen) with a readily available source of nitrogen to scavenge the nox with nn2 to reduce nitrogen oxides to produce nitrogen dioxide. With the vehicle density of a population of Australia it is not an emissions regulation to meet 0.005 gas per km. Due to the square km to vehicle ratio. Manufacturers can not justify the small amount of vehicles sold here on Australia soil. That will aid to the total emissions goals of the company. This is the reasons why "adblue' isn't a major requirement on most vehicles. Certain manufacturers that want there vehicles here won't delete emissions equipment to allow that vehicle to be sold in this country. Due to the cost of retooling for a certain market. But it still asks the question of when the nox sensor is in the realm of $600 plus for one sensor. Why isn't it just not fitted and a software rewrite just implemented.
Because dealers make more out of parts than any other point after sales.
Exactly!
35+ Years Exhaust fitter almost full understanding of the Scientific Design of Exhaust and Intake Systems, not brainwashing from interested party's training groups and government agency's re Green agenda political green house gas emissions that have very little to do with DPF's other than black soot bad white steam looking stuff good.
DPF's were designed to trap heavy Diesel particulates not light particles, and the associated burn back system either Diesel or Urea to release the same Heavy Particulates as much smaller particulates that in the public's view of what they are told is good and much better than Heavy particulates, or is it?
Particulates in the old form pumped out as black soot from exhaust's of mostly older or overly adjusted diesel injector pumps look horrible smelled like crap and did in very high concentrations (city's) cause some problems, properly tuned systems and well maintained vehicles did not cause any real problems other than the normal range given of by combustion engines.
The new systems now give of white smoke that looks like steam while a burnback is in motion, this process generates 64nm (Nanometers) size diesel particulates that can and do bypass the epidermis of our feeble human bodies and enters our blood steam (
Well we asked for it - now Euro 6 is coming to Oz
If you could come to the point rather than stirring around in your not funny saucepans of humour.
John does make me laugh. The comment "The EU cuntries being the most advanced democracies in the world" almost induced an episode of urinary incontinence ...
How true.👏
You mean the EUSSR .
Yes, they are if you call being an organized crime syndicate given legal legitimacy by people unable and unwilling to take responsibility for their lives whom thrive on being told what to do, when to do it, and how to do it all while watching those that raise questions and question decision be tortured and put on display. That is "modern" democracy. That is what politicians are saying when they state "we must save our democracy".
least it wasn't "Add-Blue" incontinency... more Ureic instancies than the standard blue urea.
...the spare grass buildup about the DPF - could mean a difference here or there in the outcome... lol. of course eth-oh makes a huge difference.
The EU may not be perfect but its citizens have more rights and protections than most.
You have to remember that engineers are subject to the whims of the bean counters, so what is actually best engineering wise is not always what makes it into the final product as cost quite often trumps good ideas. Then you also have the lawyers who determine if the business can get away with cutting corners to save more money, this was evident with the VW diesel scam even after the penalties they still made out like bandits.
Great explanation but I'd have to take issue with a couple of things. As for "e" being the first key to fail on a computer just by virtue of it being most used, I find keys fail randomly depending where the crumbs fall on my laptop and even move around. Also, you seem to deride sorting out issues in the pub but I have to say that some of the World's best ideas have come from beerstorming sessions, I just can't remember what they were as I was pissed so fck yo, oh bgger, crmbs have got in the "" key now.
WASD and spacebar are usually the most used keys...
And if you're a LoL player the keys wear out prematurely for spelling a bunch of six letters words
I'm s ck of rep acing my ke boa d so I jus put up w ith itn w. I don t th nk any ody noti es.
I remember the most worn out key being the one that makes the little space ship shoot at the other little space ships.
How about adding unneeded tiny tanks of adblue to the jets of millionaires and billionaires flying halfway around the planet for their monthly SAVE-THE-PLANETS conference in Tahiti? I'm sure it won't be inconvenient if the engines stop every fifteen minutes at 30,000 feet during the trip.🤣
By your logic. The engineers of various car companies have by a process of R&D, in conjunction with prototype models. Produced a tried and tested production model that has addressed such issues as cover or no cover on the exhaust burner. Using the logic of real events. Many first production vehicles turn out to be a disaster. More recalls and faults than you would think possible. Some even resulting in fairly serious issues. Like catching fire. Or failing to stop. These hideous new behemoth EVs. Are the brainchild of some engineer. As are the batteries that propel them. In general life. Many things conceived and evaluated by engineers. Spending millions in development. Turn out to be pants. Bridges that collapse. Buildings that do the same. Roads not fit to drive on. etc. Many engineers whilst understanding the principal. fail to understand the practicality. Seen a lot in the automotive world. Engines that are almost impossible to work on by merit of ludicrous design. Electronic components positioned where they collect the most salt and water. Guaranteed to fail quicker. The simple fact that various parts designed by different engineers. Just don't work well together in practical use. There is a lot to be said for the average guy that buys and lives with his shit box day in day out. Using it for work or play. Real world testing. If you get ten of these blokes, say with Ford Rangers. And they are all experiencing the same problems and issues with their respective cars. Then whatever is the causing effect is something the engineers got wrong. Despite the letters after their name. Or the time and money spent on R&D. In the early eighties in Europe. The cars started coming out packed with electric wizardry. They mostly went wrong quite catastrophically. The replacement models returned to a simpler format. Less to go wrong. Less goes wrong. The end user may not know the science behind the product. But is often better placed to know what is wrong with it. And also, what would help to improve it. When design engineers take time to listen to their customers. The functionality of their products often greatly improves. Don't be so quick to judge the guy down the pub. Engineers are far from infallible. Everyone can learn. And asking questions is a good way to start.
I am just picturing the " Eureka " moment. the 2 engineers where in the bar. its now 10pm. they have celebrated the birth of a new shit box, but where struggling to get the emmissions down. one goes to drain the sump, and standing there holding on to the bog roll holder trying to keep the stream from splashing on his sandles (thongs in Ausy) looking with fasinastion at the golden stream when the light bulb goes off. goea back to his mate ...." lishen to me ..how abou..how about we take some piss, and ....no ...no lhear me out....we put some in a tank....i know ..i know listen.... this is the clever bit....we pour it down the exhaust pipe.....WHEN ITS RUNNING....ha ....no think about it. it should work.....right beer?
Great explanation! My Euro car uses one tank of Adblue (about 10 litres) for approximately 15,000 km. There are early indications of low Adblue. However,a friend of mine has a Euro campervan that uses almost as much Adblue as diesel! All things are not equal so the warning about being out in the bush with low Adblue is very valid.
( there is a "ratio" - basically it is a pseudo stoichiometric ratio, supposed to be "so much ad-blue", to "so - much diesel" - difference in fuel consumption.in particular vehicles means, a per km rate doesn't mean a whole lot.)
Yep, it all depends on the vehicle and its usage
@@kadmow trucker here and you're both wrong. what adblue does is that it binds with the nox in the exhast and it turns it into something harmless. now when a diesel runs you add more air, it runs cleaner as less particulate but it also runs hotter which means more nox. that's why early 2k diesels do 60 mpg then they went to shit barely eeking 45mpg. what adblue does for your car is that instead of running it rich to deal with nox and letting the dpf catch the particulate and ruining your fuel consumption, they instead run the engine leaner, make less particulate and better mpg and not only helping the dpf by having it do less work but also due to the hotter exhaust it naturally regens the dpf so it has fewer forced regen cycles and with the extra nox created? well, the adblue deals with it later.
tldr: adblue is a crotch to help clean up the emisions. if your engine is not particularly clean you can add a bit more adblue to help with that and as a bonus they only advertise fuel consumption not adblue consumption. also just as much adblue as diesel is definetly wrong and you should have that thing checked out.
wouldnt you just top it off when ya refuel ?
dont really know my personal car dosnt have it, and i dont tramp so I just top the trucks adblue up when am refueling in our yard.
why,,oh,,why,,buy a vehicle with all this bs on it.. my 4.2tdi, s/duty, has 700nm.. gets 14 lt 100.. tows 5t... NO FKN COMPUTER.no glow plugs... cost, 25k.. how do you feel...[ 510 std, bit bigger turbo 700nm..].7 yrs, no probs.. go toyota,yeeeehh...
I worked at a Company in Norway, that had a total world monopoly on Adblue, (which is a trademark for DEF. diesel exhaust fluid) heaters and quality sensors, also fuel level sensors for all commercial vehicles. Look at the fuel sensor and adblue installations on your Trucks, Tractors etc., they all look similar that's because they all came from the same place, (made in China). The process what DEF does is known as SCR (Selective catalytic reduction) converting Nox into N2 and H2O, DEF is only distilled water and urea but you can't make it yourself because there is the quality sensor in the installation and it's so finely tuned that you will never get the right mix, It is measured optically but they were trying to make a sensor that measured the quality ultrasonically, don't know if they got so far as left 6 six years when the Yanks bought the company and moved it out to low paying lands, the company who now has the monopoly is called TE Connectivity.
@@filespec like the Norwegian guy above said those sensors are so fine tuned you can't use anything else. I tried water once I run out only to get an ad blue error "add blue of bad quality please visit service" 😅
My previous car was a Citroen C3 1.5 diesel from 2019 and it would warn you when you had 2400km of adblue left. Would have to be some serious roadtrip in the middle of absolutely nowhere for that to be a problem :D.
Although I got caught out once not realising how much more Adblue my car uses towing at highway speed. Now I just top up before a long trip. Not a problem.
Try that in a pickup or another big vehicle 3.0l diesel and then brim it to it's max weight. You will be lucky to get 5000km in total.
@@teovm yeah I know the bigger vehicles drink AdBlue much quicker. I drive a diesel van at work and that doesn't last 20k km per fill up as my C3 did.
Stralya mate 👍
My sister bought an Audi Q7 brand new which kept running out of AdBlue and stopping. Turned out the plastic container had a crack in it. It took four visits for Audi to figure out they had used a plastic tank that wasn't even as good as Tupperware.
Just changed the (fully clogged) DPF filter of my car by myself. I took the old one to the recycling center and throw it in a big container of metallic stuff.
Do you guess where all those kilos of trapped ashes will go when they will press and triturate that metall stuff?
Bingo! In the air.
Pure genius.
You do know it contains precious metals don't you and has value don't you.
Engineer's mantra. "If it ain't broke, fix it 'til it is."
The problem with adblue is it tends to crystallise, had to have my tank replaced in January, Citroen paid £750 towards the cost of replacement - £1250. Most people don’t realise that adblue should be stored between 0-30C. Friends tank went again after replacement, now had it coded out.
crystalized in very hot ambient temps?
@@18_rabbit . I didn’t say it crystallises at 30c but above 30 can produce cyanates.
not to mention dont spill that crap on ya paintwork
@@Gazzxy or even worse - your carpet, driving 500 miles with a strong smell of piss is no fun!
A 30C limit seems completely inappropriate for Oz. Fine in Iceland, but not here. Stick to Euro5 if that's the case.
Anyway, if they do bring it in, surely the engineers or beer strokers will be able to find the location of the tube that carries the Ad-Blu to the engine - somewhere beyond the "empty tank" sensor. Quick snip, "down there" , add a bit of new tube, and route it back to the Ad Blu tank. Problem solved !
Adblue is nice when it freezes and cracks the tank. Cheap too with Mercedes.
Nope, I'm sticking to my vehicle that was built before all this BS. If NZ adopts Euro 6, it's neither here nor there to me, I refuse to buy anything that has electronically serialised parts, automated driver assist features, phones home to the mother ship or any of that. I'm certainly not going to buy a vehicle with a DPF, let alone one of these systems. Call me selfish, but I prefer not to allow dealerships to attach vacuum cleaners to my wallet wherever possible. I prefer a vehicle I can fix myself if I need to. I prefer a vehicle that's as dumb as possible. My Japanese market Toyota commercial from 2006 will likely never run out of parts, and it's ECU is as dumb as a box of rocks. It manages the engine and nothing else. I'm not a technophobe, I actually know more about tech than most, which is precisely why I don't want any additional tech in my vehicle. It is of no benefit to me. My grandfather still drives his Toyota Crown he bought in the early 80s. He's a wealthy man, and well into his 80s still knows how to write computer programs. His car never let him down, and is in nearly the same condition it was new, so he has no interest in replacing it. I will be the same. I will save the environment (and my wallet) by doing as the older generations did by keeping things running for as long as possible. If it ain't broke don't fix it.
Out in rural areas, you have the issue of people stealing your AdBlue. That is quite literally taking the piss.
Adblue can be coded out and is not tested for at MOT in the UK.
not yet...... personally i feel that they will make the Uk MOT as difficult as poss soon, another way of forcing us down the EV route (have been thinking of having coded out of my t6 along with dpf bypass)
@@di5grace , maybe but the MOT tests a lot more than emissions. I don't see heavier (etc) EVs being any less prone to typical MOT failures when they get to the difficult age, and they may get difficult well before ICE cars. Agree that adblue may be included at some point. It's a finickety system where failures seem to involve swapping expensive parts.
Fooler boxes can fake the required inputs to the cars computer too.
Let's fix it by having the engineers actually spending time with those who will be using the product out in the actual world, instead of just sat in an office thinking they know what the customer wants!
Nothing wrong with the engineers, we design great products, but then the accountants take it through 'value engineering'' - which basically means it'll fail the day after any Guarantee expires.
@@Sgt_Bill_T_Co Yes I know! One of my inlaws was a drivetrain development engineer for Ford Australia. What lifespan do Ford develop their vehicles for? How long is the warranty! Two year servicing! 18K oil changes! Yes it should last just past the warranty period! So don't be the poor sucker who buys the vehicle after the warranty runs out!
Biggest problem for engineers in my experience is customers who never RTFM. I think some customers just sit on the manual and expect to understand everything by osmosis.
If you are stuck in Dingo Piss Creek with no AdBlue, can you not just get the dingos to piss in your AdBlue tank instead of the creek?
Thanks John, always wondered what that sign was about at the petrol station.
I wonder if we could get those same regulators to stop Victorians from going "Eh, fuck it" and slamming into each other on straight freeways?
Keep em in Victoria. They will bail their failed state and turn other states into the same.
Hi sir. Thank you for explaining what everything does and the reasons why it does it , I know nothing about cars but I’m still interested in the aspects that are relevant to the owner . As my late father would often quote ( knowledge is king ) , admittedly at the age of 70 I might be leaving a bit late . But of course there is another saying that rebuffs the as well . Kind regards
And I thought glorified piss was called VB
many people here in the uk are fed up to the back teeth with an blue there vehicles forever breaking down and costing a fortune in repeated adblue dof repairs this leading to many people removing the said system delete. funny how there vehicles still pass the emission standards at there yearly test inspection MOT,
without the dreaded blue p1i55 you ain't saving the world when you are having to manufacture millions of components and factory s making the pig p155 and repeated maintenance repairs it's all bull551t
... Yes, John here professing his ADBlues faith.
When he's firing on all cylinders, he's delving into the numbers, say, in this case, just how we're green Net Positive with ADBlues.
To this very day I'm still a bit skeptical about the efficacy of DEF (diesel exhaust fluid, AdBlue) since here in the States some of the exact same YMM vehicles (IE passenger pickup trucks) have it, and some don't. Ive seen dyno emissions results comparing the two and to be honest the DEF trucks did not make, in my opinion, enough of a difference to really make a difference, certainly not enough to justify the extra complexity compared to the the exact same YMM truck with just a DPF system.. To me, DEF is just another consumable to make money off of. And behind city busses in traffic good god jesus fucking Christ does hot DEF exhaust stink!! Smells like a puddle of hot concentrated swimming pool chlorine took a shit on top of steamed fish
Thanks for that description…
It will definitely stick with me…
As usual! They are taking the piss! Wonder if Pfizer own the company?
Just a thought…
If you’re low on adblue … stopping by the pub could be a good idea 👍
You mates will help too .. no doubt
@@batmanlives6456 That's just the PG description, it's actually worse in person.. much worse 🤢🤮 Hell hath no stink like a metro bus running DEF. Heavily chlorinated fish farts.. times 11
@@batmanlives6456 Now you are taking the piss! Don't let BudLight drinkers piss in your tank! It'll go down on you!
The Adblue systems on PSA Europe vehicles had a clever system of using a plastic impellor on the Adblue pump, which is guaranteed to fail, leaving you with a £1000 bill for metal impellor pump, and a new tank as the pump is built-in!
When the warning light comes on you had 1500 miles before engine "re-start" was blocked, if you didn't switch off it would keep running, as they cannot turn the engine off on a car doing 70mph on the motorway
Helps explain why my 2017 Peugoet 508 with only 60,000 kms on the clock cost me $2,060 Adblue reservoir and fluid injector. First replacement was under warranty, this one was not. I intend to sell the vehicle before I need its 4th tank. Ridiculous. Great car if it wasn't for bloody emissions issues.
New Amarok (2023) uses Adblue in Europe same as Ranger (2023)
It’s the same engine
AdBlue®️ is fancy term for urea. Not your bog standard urea (ammonia essentially, explains the smell), mind you. If it was, you could fil your vehicle's DEF (Diesel Exhaust Fluid) tank by having you, your mates, gals and utter strangers fill it up by simply relieving into it. Anyway, system that is using this principle is referred to as SCR (Selective Catalytic Reduction, some say Converter, but officially, it's marketed as Reduction).
Back to the main course. What system does diesel vehicles use: DPF or SCR? Depends on the region. But, for use in heavy-duty trucks in North America ('Murica, naturally. Nobody gives a wooden nickel about a country that is run by the world's slimiest being, posing as the silliest clown of a PM in history of human civilization, where the authorities can freeze your bank account & seze your private property by pointing out that clown is also a crook, this was already too long of digression)...
Where was I? Ah, yes! What emissions control system is in use in North America on heavy-duty trucks: SCR or DPF? Answer: both. You can find images of SCR & DPF being next to each other on the aforementioned vehicles.
Here in Australia, we have your equivalent, a bumbling, out of touch left wing fool, that is destroying Australia with the help of the green/teal movement. Who by the way, said fool, who would not do deals with the greens before the last election.
I'm willing to put a reasonable sum on the fact not a single ad blue system will last 100 thou km..Outside of the workshop are 3 everests and 2 rangers (ones a bt actually) all picked up as cheap ins write off..I don't care and neither should you the motors fit quite nicely under the bonnet of any previous bs 4wd..for the princely sum of about 8 grand I can give you 200kw without a single bit of bs to deal with..new car b fuct...thanks for the support John the second hand market in this country is doing quite well...cheers.
A ten gallon spill of adblue covers a fair bit of workshop floor. It was all hands on deck to clear it up,an eye watering experience!
American gallons or imperial gallons?
@@gingernutpreacher Imperial (U.K)
I drive Kenworths with both Euro 5 and Euro 6 engines. The Euro 5 only use AdBlue and not a lot per trip. Average about 20 litres a trip. The Euro 6 have a DPF and AdBlue. They use about 3 times as much AdBlue for an equivalent trip. Supposedly better fuel consumption because it runs dirty/efficient and gets cleaned up in the after treatment. Not sure if it saves 70 litres of fuel a trip but it uses a tank of AdBlue for a tank of fuel pretty much. A bit of a wow the first time I drove one.
My trucks are towing 100 tonne roadtrains so with less full load running it would probably not be quite as severe
well theres ya problem.. I think if ya towing 100+ tonnes there is always gona be the expectation of the engine drinking all the things somewhat rapidly
my truck was chewing adblue til the filters got changed now its a lot better.
Ah, and have we prepared for the next Ad blue shortage?
Called pig piss hear in pom land . anyone tried peeing in there add blue tank out there when the tanks empty ? Go on someone has bound to have given it a go 😄
lmao
I'm curious as well if the engine can discern the taste difference between adblue, urine and Victoria Bitter
I'm willing to bet some people can't
Too many electrolytes in piss. It will screw up the SCR reactor. Also, the concentration of urea in piss would be generally incorrect and too variable. The sensors would know that something is wrong, and then you would probably find yourself walking home.
The best after treatment is none. As for the emissions just keep the vehicle for 15-20 years and stop consuming new products.
A Dad joke I couldn't leave on the table:
DEF systems are DEFinitely questionable, hopefully soon to be going away inDEFinitely.. They suck harder than DEF Leppard.. and DEF DEFinitely has an unquestionably inDEFinite DEF supply
I am driving a 2016 Honda HR-V 1,6 Diesel that is Euro 6 and it is not using ad-blue.
Have the Honda technicians just been fiddling with the combustion process til it was compliant or should i fear VW levels of software trickery ?
And what's your take on EU'S 0 emissions for car's from 2035
I do not at this point see where all the unicorn dust magic shall come from to make the power grid ready and the wallet full enough to make the normal person afford a decent range car without buying used fossil burning car's.
Not to mention the lovely mass car fires when most cars would be electric.
Sorry for grammatical and spelling mistakes as English is not my first language.
Turn it up. I'm def
Both of them are just more ways or gouging into your pockets. By the time you deduct the additional manufacturing cost/pollution for each system and the increased maintenance costs incurred from these systems failing, you have to wonder if the environment is any better off.
Then of course if you use adblue you are buying that forever after it has been manufactured in an undoubtedly pollution free manner.
It all gets to be a bit like Gillard and her "cash for clunkers" scheme. A major flop.
Didn't answer the obvious question of whether you can just piss in the tank?
Simple answer no you cannot as the systems detect quality
@@darrylpaulhus3069must be drinking Bud Lite........
yep; hired a Ford Everest from Melbourne to Perth last September, had to top up the AdBlue tank at Norseman. A real learning experience. ps: was not aware the engine would stop if the AdBlue tank was empty,. so glad I did fill it up when I did. Book said one tank would last 5000Km.
AdBlue. I thought it was a range extender tank🤣
@@IT-sq5rj - ha ha - top-er-up... diesel or 98 (the best you could get).... lol...
You're lucky just topping it up fixed the problem. In my Peugeot, simply topping it up has no effect. The software needs to be re-set using genuine Peugeot OBD software. Generic OBD devices do not fix the problem. Great little earner for the PSA Group.
@@steve8567I.m in Canada, and i drive a 1994 dodge Cumins Diesel They have mechanical injector pumps and injectors No catalitic convertor, or egr, or ADblue tanks, just a muffler and tail pipe.It's so mechanical and simple it will run completely with out electrical devices except to run the starter.I just hope they Goverment lets me keep it. We are in -35c weather right know so its pretty smokey on start up and clears right out when warmed up. I've replaced the entire fuel system a year ago so i know it's running right. It will be my one and only Diesel truck. My hope is there are less and less of them on the road each year, An maybe the goverment will leave me alone
An engine would run cleaner and fresher with the exhaust been allowed to come straight through without a DPF DPF gets blocked and then you get black smoke all the time class a lack of power plus you need open heart wallet surgery to pay for it add blue don't do nothing
Not sure how many AdBlue-cars you've driven, but here in Europe besides it being mandatory to prevent engine start when you out of AdBlue, a very early and generous warning system is also required, giving you the first warning that a refill is required 2400 km before the end, which should be plenty in all halfway civilised regions, including most places in Australia. It then gives subsequent warnings at every engine start, counting down remaining distance in 300 km increments, until, when you really get towards the end, it will say something like "5 engine starts remaining" until "One engine start remaining". If at that point, your one remaining trip does not take you to an AdBlue refill, it really and truly will refuse to start.

Just fill up your add blue tank with diesel problems solved
Hey John, if I run out of AdBlue in the busted arse scrub, can I put a little water or filter some piss through a coffee filter to get enough to keep me mobile?
Currently replacing the engine in a 2001 TD42 powered Patrol ute that the owner "cleaned out" with one litre of Add Blue. In the fuel tank.
Since watching people filling their adblue tank I now really do not like diesel at all.
Thinking Rational ideas are not necessarily the preserve of experts as seen now with what happened during covid.
AdBlue is implemanted in euro6 ( either a , b, c...and now revision ap i believe) to get NOX down. Some euro6 engines have it some not as they comply. In some cases the same engine has different power output the lower power 2l turbo diesel under 150hp will get away without adblue but the same engine with higher power and over 150hp will require adblue to comply. And addblue will not be used at a rate that you will need to fill up like you do with diesel.... i did not realized in Australia a car could be brand new and not be euro6 equivalent emission standard...
Vehicles that don't use DEF inject raw diesel into the exhaust and burn the soot in a high temperature cycle
Our GWM Cannon has a DPF. It does automatic burns but if you dare interrupt a burn three times, it can and does go into limp mode and drop the power immediately. Weirdly enough, the owners handbook shows that overseas models have adblue, the filler a smaller nozzle beside the normal fuel filler. I wondered why they had a long rectangular fuel door and when you open it, you notice that the diesel filler set well over to one side. That’s why. Overseas the second filler would be beside it taking up the free space that’s there on our version.
Probably goes into limp mode cause a full dpf will restrict the exhaust flow. With no EGT sensors, the safe thing to do is burn less fuel so things don't overheat
A large car manufacturer did wind up putting a heat shield on their DPFs as a recall a few years ago due to grass fire situation. I'm not sure that OEM engineers get it right every time.
Hi, John! Just stumbled on your channel, have subscribed. Your explanation of AdBlue, and Catalytic Converter, was just the best I’ve come across. 👍
I miss my 1970s shitbox😥
Most of the 1970's shit boxes that are watching are offended dude.....
Add blue works with the CAT not the DPF. This comment is not to John just other people who a watching who didn't pick that up.
A very informative video.
Here in NZ I drive an off road euro truck totally in the forest/Bush and it uses adblue or it won't go!!.
But all the forest harvesting machinery use far more diesel than the trucks don't require adblue .
Where is the logic in this?? Poor possums breathing in all the shit from the machinery but at least the trucks are helping with clean possum air!!
Keep up the good videos (dude)
I'm not surprised John has had 300 wives..they all tried to have a conversation which didn't last 20 years
But of course in the future Australia we will not get caught with the piss tank empty up at the cape or down the Gunbarrel because we will have out Electric Utopia BEV utes that can be charged by the great Australian sun by plugging them into the nearest tree, or termite mound, or sand dune. Don't throw your left over piss away though because you just may have to drink it to stay alive.
John if you are interested in more information on exhaust emissions,ican put in tuch with the person who knows everything about it ,No diesel engine needs to yse Add blue with the other technology that is available,it has federal government accreditation in the U.S.A. ,E.P.A. approved,
😊so John it is obvious you haven't red the comment I put in the Collum about the non-use of add blue when other technology on exhaust system is applied ,it has federal government accreditation.and E.P.A. in the U.S.A. this would bring Australia up to E.U.R.O. 6 STD at this point
Just look at what "They" are doing in the Netherlands! Closing down farming! So where is the pig piss going to come from?
Urea is made artificially by reacting methane and nitrogen in an industrial process.
@@AutoEngineerVideos My Ford Galaxy Ecoblue was a nuisance for the Addblue warning coming on when away on holiday! Now I have a Nissan Qashqai E Power(John hates them) so no more adding blue and increasing the cost of fuelling the car.
The engineering behind all this stuff is fantastic. It's a great shame that diesel is falling out of favor when one considers how clean it can be if these systems are operating correctly.
Countries like the UK do however need to put a little more regulation around modifications and emissions checks to make sure these systems do keep working through the life of the vehicle. At the moment one can broomstick the lot of it and get it all programmed out and still pass an MOT emissions check.. I suspect many are removed due to the huge costs when things go wrong.
Yeah, Ford commercial vehicles seem to be most prone to add-blue problems.
When the emissions check looks for smoke under no engine load and very little else, no diesel that's running half way competently at all will fail emissions on this, even without a DPF.
Maybe just maybe the adblue brigade like having the piss taken outta them …
Are all the coal-fired power stations in 'Straya Euro 5 then?

John, I have one of the first Euro 4 compliant NS Pajero’s that hit the country. I had nothing but problems with the DPF system for the first 3 years of its life and the dealer’s had no idea on how to fix it. I fixed the F@#ken thing though.😉 and you would probably guess how. I still have it now with no issues since.
I was too scared to have the EGR altered. I sold my diesel. I gave up trying to give a crap about the fracking DPF.

@@richyfoster7694 No, a bunch of self serving lieing bastards....🙄😳🇬🇧
I got both DPF and AdBlue on my 2.0L diesel hatchback, and being a frenchie, the DPF uses a special aditive to lower the regen temperatures (Eolys 176).
Yup, we now have two Euro6 French cars, and it took me a long time to understand that the special additive for the DPF (or "FAP", as Peugeot calls it) is not used during the regenerative cycles (that is just accomplished by creating hotter exhaust by injecting more fuel later in the stroke), but is added to all fuel that ever goes through the engine, in order to modify the type of particles, lowering the temperature at which they burn off. This both lowers the amount of additional fuel that needs to be burned during regeneration (aka "burn-off"), but also allows the use of much more moderately priced materials. I seem to recall that it lowers regen temperaturs from somewhere around 600°C to just over 400°C or so. Brilliant stuff.
@@pinkdispatcher The AdBlue is added to the exhaust, not the intake air (Unless you've got one of Toyota's new - and very frightening when you look at the properties of ammonia - ammonia engines) all that's added to the intake air, apart from fuel and mechanical work to compress the air, is recirculated exhaust gas as this reduces combustion temperatures (At the expense of peak thermodynamic efficiency) in order to break fewer nitrogen molecules apart so fewer NOx compounds are formed.
Regeneration is a sign your car is not being used for what it's good at, namely intercity travel at 80+ km/h. Any car that's able to spend a decent amount of it's time cruising at those speeds will burn the soot out of the DPF in normal operation and never need to regen at all.
@@peglor The last paragraph is incorrect.I do 350Km at 110km/hr regularly non stop in our Land Cruiser or a Diesel Hi Ace,both regen at regular intervals during the trip.It is good to have a DPF guage on the dash read out so the driver can see how often it regends,and the Diff Pressure across the DPF,and a regen switch if neeeded,but i have never had to use it.
@@paulbarry1044 Apologies for not being clear - when I say never have a regen I mean never suffer the raised idle speed, lumpy idling, smelly exhaust and so on that go with a forced regen, where the engine is trying to create exhaust temperatures high enough to burn the soot off the filter while being driven slowly in traffic.
@@peglor Even driving slow in traffic with some idling, they will do a burn.I think problems happen with numerous short runs,and the vehicle never gets a chance to regen.Engine also not getting up to temperature during short runs does not help.With our Diesels,we have never had a DPF issues,and some are over 8 yrs old and done huge mileage.
At a Pinch !! Can one pee in the Add Blue tank to keep going in the outback ?? 😉😉
It shouldn't need to be said but DO NOT piss in your adblue tank lol.
Also some adblue systems will derate rather than completely locking you out. Limiting engine power and RPM.
I was just thinking if you could just piss in the Adblue tank.
Always use fertiliser
I’m sure a bag of urea isn’t that much, just need to add water
If Ford did indeed know much about their Rangers, the automatic transmissions would not still be falling out of them left, right and centre...
I think the pecking order in manufacturing is:
1/ Bean Counters - keep costs down and maximise profits.
2/ Lawyers - what can rhe business get away with to maximise profits.
3/ Engineers - have to design the products to appeal to consumers, all within limitations of what 1 and 2 dictate.
I MADE IT DAD
I can remember driving heavy B-Doubles for a major company and the shortage of Ad-blue in early 2022. I had to get Ad-blue from another of our companies depots (ours had run out) and it was an all in bun fight to get permission.......my depot boss had to have written permission from the other depot boss in a chain of emails that then had to filter down to guy in the workshop with the bowser key. Fleets were paying $4 per liter for the stuff.
one way to fix all your exhaust probs.. run lpg..
John, I see an episode of DIY addblue, any chance?
Generally it depends on the country of origin of said vehicle as to whether it has DPF or Adblue after treatment systems as our government is to lame to specify the best option being Adblue the better of a bad idea.
Personally I’d rather have water methanol injection 🤪🚀
Thanks for this John. I'd often wondered about ad blue but couldn't be arsed to look it up, anyway your explanation is much more entertaining than Google. My S class Merc. Uses it.
Very well explained JC, thanks. My current diesel powered vehicle is most likely the last I'll ever be driving so I may not get to enjoy the feeling of ever having artificially concocted pseudo "piss" in a tank onboard, (makes me think of an acoustic mobile shitoire` for some reason).
So EV drivers and potential Diesel drivers will have something in common ye olde range anxiety. Guess you can carry a bucket at one of those diesel generator power EV chargers and ask people to do a number 1 for you in the bucket while they're waiting to charge their EV or just help yourself to the AdBlue on the generator if you are lucky, assuming someone hasn't already stolen the genset!
I haven’t checked recently but when I lived in Edithvale on the edge of Port Phillip Bay, it was possible to see a tinge of nitrogen dioxide on the horizon and the edges of the bay. It was the colour of black tea, cola drinks or bromine.
This all goes away on a clear windy day.
yes, the Pinto existed because Ford did "lots of testing" and enginerding. they had really RULLY good reasons for making those design choices.
Was the first thought I had when John mentioned "good car manufacturing research"!
Urea? Isn't that explosive 😂
Adblue's nothing like urine - there's no blood in it for starters.
(You can scrape Euro 5 with about 170 bar peak cycle pressure, with adblue you can go nuts, so 210-220 or more with consummate efficiency gains as limited by the engine structure. It also tends not to cut in for up to an hour of engine start so your Euro6 engine will very likely be substantially dirtier than Euro5, especially on short trips. It's good technology for machines which run all day, but not for commuter cars.)
Off highway seems to have a break point at 100kW below which machines don't need it, so there is a sweet spot for tractors at about 140hp
I learnt today that there is a Silverton in South Africa. The only other Silverton I knew of was an outback ghost town in NSW, 25 kms NW of Broken Hill.
TIL there's a Silverton in SA and one in NSW. The only one I knew of is an old saxon village in Devon.
Just outside Pretoria.
Just a comment to improve the algorithm...
Adblue/Euea/DEF does degrade (which will trigger a check engine light or worse!) when stored in normal comfortable for humans temperatures of 70F and above, its shelf life is limited because of this.
I have a straight pipe exhaust and less repairs.
John, great video but when the first warning light for any car fitted with an AD Blue system flashes on the dashboard alerting the driver that it needs topping up there is at least a minimum of a 1000 miles that can still be driven before the ECU shuts the engine down and with many many cars now, like my DS7, it's 1500 miles, then another warning at 1000, then 800, then every 100 until it stops altogether and lets face it if you do let it get to zero then you probably don't have the IQ to be allowed a licence anyway. I know Aussie land is vast but even a 1000 mile warning of impending doom is far more than any driver needs to enable a top up.
In europe, the Euro6 sprinkles the adblue even on idling. That cloggs up the DPF with the Urea stone.
Also new 2023 hiluxes in farms go to the shops for DPF delete. Because the do the ReGen like in every 200kms and even when idling. For preventing to set a field in fire when harvesters do theyr job and you go to check the progress, chat with the operator and let the aircon work on a hot summer day. And the dpf starts burning with 600c and you are standing in a dry hay or crops field.
Neighbor's 2016 hilux started to catch fire after driving in Peat moss
Dude. Thanks. Wondered this but too stupid to Google it myself 😂
Thank goodness for the diligent work done by our Federal Chamber of Automotive Industries. The other thing John, my Holden Ute takes offence at being referred to as a shitbox. It was built in 1982 anyway. It and I do not care what comes out of the exhaust except the sweet 253 note from its twin system. I will go back to walking before I use either adblue or an electric car. Jeff.
There's a dpd/f disable mode on trucks when the pto is on, aimed at fire trucks to stop the fires starting from the 600°c the dpd/f's get to. Old mate hasn't worked on many vehicles if he thinks a full guard doesn't get full of grass... Plus it holds heat in at freeway speeds instead.
You cannot eliminate exaust from combustion. You can vaperize it , crystalize it or even liquify it. But the only way to eliminate it , is to stop driving 😂😂
Adblue treats NOx and Particulate filters filter particulates … seems pretty straight forward.
As I understand it reducing particulates requires high combustion temperatures which means that more NOx is produced and most NOx compounds are lower energy than Carbon Dioxide, so carbon rich fuels like diesel produce more.
NOx generally requires high temperature and pressure to form. NOx production during DPF regeneration burn is negligible.
@@AutoEngineerVideos
I was talking about the combustion chamber … modern diesels product higher combustion temps …
@@DrDezaronow I see what you're saying (I thought you were talking about the processes in the exhaust to clean up the emissions). Yes, you're correct.
What is Adblu ? It is a name drummed up by the German Automotive Society for Diesel Exhaust Fluid. Why we just dont call it DEF like most countries on the planet is beyond me.
John, Could you do a video about add-on Propane Injection.
I have seen these mentioned as a small performance enhancement on diesels and maybe also gasoline engines. I realize they aren't like a nitrous injection system but used to help a truck or motorhome climb a long or steep grade for a little extra oomph.
Even a simple system that only provides and extra 20-30HP can be helpful at times.
What is the story on these units and their applications?
propane has an "octane rating" or anti-knock rating of 120 , with a diesels high compression ratio of 16 or 18 to one plus , propane performs very well , even better than a petrol engine with a ratio of 9 to 10.5 [ like my ls1] , i actually run my ls1 on propane and it goes like a scolded cat ! its due for a head recondition /headgasket replacement [ using water gradually now and after 300,000 km's could probably use a valve grind ] so would love to take this oppertunity to fit a racing cam i got for a swap for my old high ratio diff gears some old mate wanted for his turbo ls1 [ for top speed] while i send the heads to pavtek [victoria] and take advantage of their deal that includes bigger stainless valves/new seats/5angle valve job/ cnc machined combustion chambers and port job , flowed on the bench to 700hp on pump gas , and get them to give me the 12.5 to one pistons to take further advantage of lpg's 120 octane to make my commie ss a environmentally friendly friggin monster!
I see John as very car hypergamous.
