So EGR does reduce engine combustion temps but not directly via the egr cooler. The cooler only exists to get the exhaust temps and pressure down to safe intake levels. The way EGR reduces engine combustion temperatures is by causing a weaker/smaller combustion. If you take say 50% of the intake charge and replace it with (inert and non combustible) exhaust gas, you have (give or take) 50% less oxygen in the cylinder. Your ranger knows the position of the EGR valve and uses a MAP to adjust the injectors to suit. So in this 50% arbitrary example you ranger (while the EGR is fully open) will have an effective displacement of combustible gases of 1.6Lt instead of 3.2Lt. EGR makes your engine run cooler by reducing the power of each bang, therefore, yes blanking off the EGR will raise your combustion temperature. A bigger explosion in same space means more heat generated... ....HOWEVER, your ranger will only have higher combustion temps at idle/closed throttle compared to a non modified system. AND IT JUST SO HAPPENS that the factory ranger cooling system is more than capable of dealing with cooling an idling engine. So you will not see an increase to your running temps on your coolant temp gauge. Combustion temp is not the same as engine coolant temp. The thermometer for your coolant is not jammed inside the cylinders. - Does EGR reduce combustion temps and N-O emissions? Yes 100% - Will blanking this increase the temp gauge on your dash? No, your radiator can handle idle temps with ease. - Will the increase in closed throttle/idle combustion strength increase wear over the life of your engine? Not of much as gumming your intake valves with oil and soot crud is going to. EGR isn't there because its good for your engine or efficiency, it there because exhaust gas is nasty stuff and all the soccer mums driving their Navaras and Rams in the city will cook the air quality without it. If emission laws were abolished you can bet your butt manufactures would stop bothering with EGR altogether. Anyone claiming EGR will make your engine 'run hot' is either completely misunderstanding how combustion temps vs coolant temps work, or are deliberately creating clickbait for views. As always good video mate.
@@gough184946 in diesels, the cylinder is always fully open. I’m not sure what you’re stating here. The 50% cylinder reduction is an arbitrary number I plucked out of my butt for ease of explanation.
Awesome mate, as a mechanic I know it won’t make it run hot by blanking off the egr but for the non believers you did a great job of proving this is just a myth.
It's has nothing to do with the temperature of the cooling system, it is about the temp of the combustion gases, the engine temp will stay the same but the combustion will be hotter and therefor it will release NOX gas, which is bad.
Excellent explanation, with facts. Cant beat that. Maybe the haters will now realise that a factory egr system actually taxes the cooling system , via the egr cooler. The fact its called a egr cooler surely is a giveaway.
You will crack the head because the burn is hotter. I was wrong. I have now changed my mind, & I have just the other day made an STS blanking plate & removed the EGR cooling pipes on my 2006 Mazda BT 50 2.5 turbo diesel 104000 km the engine now runs cooler. You are one of the smarter people who makes RUclips videos.👍

I have a 2017 Ranger,had AdBlue delete,EGR delete and a performance stage 1 remap today,,totally new truck to drive,gained around 60 bhp and pulls like a train.
5 major issues with egr 1/ inlet manifold gains deposits and needs cleaning every 100,000km 2/ Egr cooler needs cleaning at the same time as egr valve every 80,000km . Egr coolers overheat and split causing engine damage from leaking coolant . 3/ poorly performing EGR systems cause poor throttle response and lower fuel economy 4/ some egrs system operate that poorly fuel economy is never stable from new 5/ some engines wear injectors very fast partly due to combustion contaminants caused by egr particles NONE OF THESE ARE KNOWN BY THE PUBLIC oz Bush Electronics
@@gogogeedusYes your correct the FULL egr system is at fault by its design . By its design as an assembly it causes shorter engine life , Simple Particles or soot cause higher engine wear via oil contamination and direct contact with components .
Imagine how many engines were destroyed by faulty EGR components or the reduced lifespan of all those engines, that's definitely not better for the environment. I have a D40 Navara and since I've done the EGR blanking plate it's reduced my fuel consumption from 10.3L/100km to 9.0L/100km, with no other changes, maybe some exhaust gas was leaking past the valve??
Installed the egr blanking plate to my PX1 Ranger recently. Pain in the arse to install, (with my limited mechanical skill). But,, I feel it's providing better fuel economy, & allowing engine to breath better now. Engine temp has not changed.
@@xnsretroplan No, incorrect. As stated. the oil that's circulating in the intake manifold, will clean the intake over a period; due to the nature of oil composition. Modern oils consist of approx 15-20% additives, which include detergents to assist in cleaning the engine. When they make their way through the system, over a period they will clean the gunk out that's build up, - off to a reasonable level.
@@sysmith9910that’s a load of rubbish. You need to manually pull the manifold and clean it by hand a mixture of additives is not going to clean 10s years of built up sludge out of your intake manifold stop lying. Do the blank, delete mod and get a intake manifold removed and cleaned.
blanking the EGR is pointless. like you said it only opens at below 30% throttle. stick a catch can on and the EGR is never a problem. it's a system designed to lower NOX emissions at low load conditions like idling and town driving. it does just that. before I understood how the system worked I was one of the people that thought the EGR was making the engine run worse for the sake of lower emissions but that's not the case. any throttle position where you would notice power differences has the valve shut unless the unit is defective or clogged up with sludge which is why a catch can is a necessity on diesels with an EGR system.
Catch can is certainly the right idea (just use a proper one such as a Provent not some of the stupid aluminium cans) but even with a catch can the EGR is definitely a problem. It will still fill the inlet with soot, it will just be less of an oily sludge and more of a powdery accumulation.
your explanation is valid tho clean oil circulating through the breather does no harm, unfiltered exhaust gases block up the intake, catch cans don't remove 100% of the oil , blanking plates remove 100% of the exhaust gases.
@@abdautomotive yea you're right a catch can doesn't remove 100% of the oil but a catch can is a legal modification. a blanking plate is not. whether the laws are right or wrong you just have to abide by them. I'm not getting my diesel defected and put off the road with a massive fine
No catch can you need the oil to lubricate valve seats check your valves clearances after 50,000 Kms and you will see they have closed slightly due to the the dry carbon the best thing i have found I fit a blanket plate with a 7 mm hole gets rid of any tunes make sure inlet manifold and egr are clean you will be surprised how long the engine oil stays change oil and filter everywhere 6000 Kms
there are other heat sources that add to the engines operating temperature such as in an auto the heat exchange unit on the transmission adds heat , the egr cooler adds heat , the egr valve adds heat because they are all being cooled by coolant running through these devices , i have "fixed" my ranger its a process but it will make the ranger so much more reliable , not enough time to go through it all tonight but this guys video's have helped big time
P:S , my 2016(pre DPF) rangers temp has been so consistent since all the preventive maintenance was done including a sensible dyno tune , there are two other things i want to do one is change out the thermal bypass valve (WHICH OPENS AT 80DEGREES and more importantly these factory thermal valves can fail closed and destroy the transmission if you are not paying attention) in the transmission for a fully open valve which will reduce trans temp and ultimately engine temp and secondly the factory torque converter to a more positive converter which will provide a more positive drive especially off the mark and also reduce trans temp even further and again reduce engine temp ever so slightly ' if you want your rangers engine to survive ! these measures are a must .
I did the delete at the exhaust manifold when i took it off to put a new turbo on. Runs so much better, but the exhaust is stinky like a jet engine. 3.2 Doesn't run hot at all.
Diesels pretty much always run "lean". They always have the air intake wide open, the accelerator alters the amount of fuel being injected. It's not like a petrol engine where both air and fuel feeds are reduced at part throttle. So when idling, yeah diesels run incredibly lean. But it's not harmful to them.
Can doing this damage the DPF? Some sites say it can through lower back pressure, but that seems unlikely given the valve isn’t always open anyway? Great videos, thanks
Yeah, it's not necessary. As the video shows, the EGR valve is only open at low load conditions. The cooling system is designed to cope with sustained maximum load - like towing a van up a big hill. So EGR blanking only affects those periods of low load, when the cooling system isn't working hard at all.
how it reduces ignition temps, because diesels dont have a throttle, when you are in low "throttle" position, the amount of air your engine draws in has significantly more oxygen in it than what is required, so when diesel is injected, you will have a lean burn enviroment due to the low stoichiometric mixture, this creates high temps in the combustion chamber. so the egr diverts oxygen depleted air, cools it, puts it in the intake and this balances out the stoichiometric mixture ratio, when on higher throttle %, it slowly closes, ideally you dont want perfect combustion, unburnt fuel is actually a coolant to the cylinder temps. high ignition temps cause nox emmisions they want to reduce,
So what this tells me is that you need the egr the most when you're sitting in traffic in cities at stop lights or heavy traffic. It's pretty much exactly when you would want it. When you're near stationary or stationary, with lots of other cars and people around, you and the pedestrians are not breathing in so many harmful gases....
What it doesn't tell you is that it's exactly at this time when your engine fills up the inlet tract with oily, sludgy goop which will reduce the air flow at all times to the engine, causing extra fuel consumption, rich running, extra hot combustion leading to molten pistons eventually. The small advantage gained at idle is well and truly obviated when the chemical cleaning agent used to clean out the inlet at huge expense is flushed into the environment together with the removed goop.
A combustion chamber is designed to operate at very high temperatures. One or two degrees from blanking the EGR is not going to damage the engine. What do these people think, that the combustion chamber is going to get too hot and crack? What is going to happen?
Maybe a loaded question…would this apply to most diesels? Done it to my old camper due to clogging and felt it made a difference (wishful thinking maybe…but it did stop the shooting up). Want to do it my new Fiat Ducato camper, and probably my x350 (yup.:.I know everyone hates them 😂).
It seems to me that that the EGR system is there primarily to reduce NOx emissions in built-up areas (where you're likely to be travelling under low engine loads). NOx reduction in built-up areas is primarily desirable - indeed necessary - to improve air quality. High levels of NOx in highly populated urban areas does indeed kill people and makes life damned miserable and in many cases unbearable for so many more. This video is an excellent demonstration that there is no EGR under high engine load. And if there were then it's likely that - EGR cooler or not - the engine and head of the motor would run hotter under high loads. The EGR cooler would likely be pretty useless when the engine is working hard. But at the same time, it probably is true that at lower speeds and loads - when EGR actually is happening - EGR cooling is probably necessary in order to reduce undesirably higher engine operating temperatures and particularly when it comes to the thermal impact on components in the engine head (that due to their nature and function aren't cooled by the engine cooking system) that might be reached if EGR gases weren't cooled at all. I'm not an expert in this area at all. But this explanation would make sense.
I would like to explain how EGR works in terms that the Average Aussie bushwakker would understand, lets start by saying that a lean mixture burns more oxygen and a rich mixture burns more carbon for starters, then I should say that burning more oxygen creates more heat which in turn lets NOX gases out whilst the rich mixture stays cooler but can release unburned carbon if it is to rich, So the EGR is there to reduce the combustion temp during lean burns by adding exhaust gases, the exhaust gases take up some of the volume of the combustion chamber where oxygen would normally be present, therefor eliminating excess oxygen during combustion and keeping the combustion temp lower, one of the reasons you need this system is because a diesel inlet manifold doesn't have a butterfly valve to restrict oxygen flow and under certain load conditions the oxygen supply will be reduced but the fuel will not be, and EGR can keep the balance between to much carbon in the exhaust and to much NOX.
The critical million dollar question I’m asking myself is what about car insurance cover in a major $$$$$ accident ?? …. If the car is unroadworthy it is potentially not insured and gives your insurance company a way out to diminish or refuse your claim . Any advice on that would be appreciated.
Hi.My 2012 3.2 ranger turbo has blown....We had already spent a quite alot money replacing other parts like injectors and other stuff.Would you recommended we fix it and sell it or keep it?It now has 260 000km on and it is a automatic
@@abdautomotive it was a blown turbo...but I want to know,I want to blank the EGR but can I only put the plate on the passenger side but not on the other side.Because the one by the exhaust manifold is a huge job for me but the one at the intake side is much better.
hey mate does blanking the EGR via remapping solve this issue or should the plate still be installed and if so can you guide me on why. have a px1 doing 120k kms egr cleaned a few months ago and already clogged again and valve stuck closed. faaking pain in the arse
I am considering buying an Everest. I hear the EGR coolers fail which can ruin your engine, not sure how true that is. If you block the EGR, does that remove this risk or is the risk still there?
will be doing videos in the up coming months on the newer Ranger/Everest EGR coolers, they are no where near as bad as the PX1 first generation coolers
My understanding of how it works: Recirculating exhaust gas reduces the combustion temp by reducing the available oxygen in the combustion chamber. But in order to run at a given RPM, say idle RPM, a given amount of power, therefore heat, is required. (The heat expands the air which produces the power, so power=heat) So in order to maintain the same RPM, more fuel has to be injected, which ends up producing the same heat overall. This is why blocking the EGR will slightly improve fuel economy. Recirculating exhaust gas reduces LOCAL high temperatures in the combustion chamber. It doesn't reduce the overall heat produced.
In some countries the Rangers come with no EGR system installed. It's a complete factory delete. Personally, I don't really care about performance gains from an EGR delete. I just prefer to not have carbon gunk buildup in the throttle body
Where on earth did you get that strange 1 John 4:4 from? Mine reads But you belong to God, my dear children. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world 1 John 4:4 (NLT) and here is the same verse in the LSB - You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world.
The role of the EGR is to maintain an even temperature during the running of the engine, mostly at idle and low load RPM. This is similar to a Petrol engine closing its throttle body gate to reduce air, hence the effect is the same, it creates a lower oxygen environment for the fuel to burn thus lowering the temperature of the gases during the ignited stage in the cylinder. That’s why you pull over when a petrol engine overheats. You let it idle to cool down. A Diesel cannot do that without an EGR. But yes the consequence is soot and deposit build up that requires extra maintenance.
Great news everyone, I fucked off my ranger and replaced it with a plug in hybrid peugeot 3008, so far I have drived 2,860 Kms on my first tank of fuel and still have plenty of fuel range. I charge i daily from my solar at work and have the dino juice for long trips. No more clogged EGR and it has a quick 0-100 in 5.7 secs. Looking forward to the plug in ranger next year, maybe it will be tempting me back :)
Can you just install a blank plate or it requires more than that? I mean it’s must to make changes in ECU and tune after installation of blanking plate?

Thanks, your explanation makes perfect sense.
Can I only blank the one on the passenger side?It will be much easier.The one by the exhaust manifold is a huge job for me.
Can we add an extra "oil cooler' to aid in cooling the engine to compensate for blanking the egr?
If I understand this right it’s 100% not required. If the air is cooler coming in, why would the oil be hotter ?
Yeah, it's not necessary. As the video shows, the EGR valve is only open at low load conditions. The cooling system is designed to cope with sustained maximum load - like towing a van up a big hill.

Hi, Thanks for your videos. Question, do i have to blank the egr valve on the computer, or just the mechanical procedure it's enough,?
I would like to explain how EGR works in terms that the Average Aussie bushwakker would understand,
lets start by saying that a lean mixture burns more oxygen and a rich mixture burns more carbon for starters,
then I should say that burning more oxygen creates more heat which in turn lets NOX gases out whilst the rich mixture stays cooler but can release unburned carbon if it is to rich,
So the EGR is there to reduce the combustion temp during lean burns by adding exhaust gases, the exhaust gases take up some of the volume of the combustion chamber where oxygen would normally be present, therefor eliminating excess oxygen during combustion and keeping the combustion temp lower,
one of the reasons you need this system is because a diesel inlet manifold doesn't have a butterfly valve to restrict oxygen flow and under certain load conditions the oxygen supply will be reduced but the fuel will not be, and EGR can keep the balance between to much carbon in the exhaust and to much NOX.

If the car is unroadworthy it is potentially not insured and gives your insurance company a way out to diminish or refuse your claim .
Any advice on that would be appreciated.
Hey mate, can regular cleaning of the carbon buildup in the engine prevent EGR cooler problems?
EGR reduces combustion temperature this in turn reduces lean burn and NOX production.
Since the 70`s egr has been an issue . Never been an issue in regards to temperature when the egr is blocked . An engine likes to breathe fresh air .
Hi.My 2012 3.2 ranger turbo has blown....We had already spent a quite alot money replacing other parts like injectors and other stuff.Would you recommended we fix it and sell it or keep it?It now has 260 000km on and it is a automatic
if you've done injectors already keep it, turbo is an easy fix $500 of ebay, 3 hrs work
@@abdautomotive it was a blown turbo...but I want to know,I want to blank the EGR but can I only put the plate on the passenger side but not on the other side.Because the one by the exhaust manifold is a huge job for me but the one at the intake side is much better.
Does blanking the EGR give an EML? Want to do it but also don't want to have to mess about for an MOT here in the UK. Thanks in advance all.
I've blocked mine and no difference in running temp even when towing a 2.5ton van
Depends on your definition of hotter. Not hotter coolant but hotter combustion and more NOX.
hey mate does blanking the EGR via remapping solve this issue or should the plate still be installed and if so can you guide me on why. have a px1 doing 120k kms egr cleaned a few months ago and already clogged again and valve stuck closed. faaking pain in the arse
hi there, just want to know will blanking my egr system will it put it into limp mode?
Did you have to change the code in ECU after blocking and bypassing the EGR?
I am considering buying an Everest. I hear the EGR coolers fail which can ruin your engine, not sure how true that is. If you block the EGR, does that remove this risk or is the risk still there?
will be doing videos in the up coming months on the newer Ranger/Everest EGR coolers, they are no where near as bad as the PX1 first generation coolers
My understanding of how it works:
Recirculating exhaust gas reduces the combustion temp by reducing the available oxygen in the combustion chamber.
But in order to run at a given RPM, say idle RPM, a given amount of power, therefore heat, is required. (The heat expands the air which produces the power, so power=heat)
So in order to maintain the same RPM, more fuel has to be injected, which ends up producing the same heat overall. This is why blocking the EGR will slightly improve fuel economy.
Recirculating exhaust gas reduces LOCAL high temperatures in the combustion chamber. It doesn't reduce the overall heat produced.
What app/OBD2 are you using to read your egr please?
topscan, i've done a vid on this
In some countries the Rangers come with no EGR system installed. It's a complete factory delete. Personally, I don't really care about performance gains from an EGR delete. I just prefer to not have carbon gunk buildup in the throttle body
Absolute common sense, unfortunately it rarely prevails
Where on earth did you get that strange 1 John 4:4 from? Mine reads But you belong to God, my dear children. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world 1 John 4:4 (NLT) and here is the same verse in the LSB - You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world.
The role of the EGR is to maintain an even temperature during the running of the engine, mostly at idle and low load RPM.
This is similar to a Petrol engine closing its throttle body gate to reduce air, hence the effect is the same, it creates a lower oxygen environment for the fuel to burn thus lowering the temperature of the gases during the ignited stage in the cylinder.
That’s why you pull over when a petrol engine overheats. You let it idle to cool down. A Diesel cannot do that without an EGR.
But yes the consequence is soot and deposit build up that requires extra maintenance.
This is HOT!
The FORD IN Ford makes it run hot and destroy itself
If there is no EGR, people will stop buying new part from the factory and rebuilding their engine.
i agree
Great news everyone, I fucked off my ranger and replaced it with a plug in hybrid peugeot 3008, so far I have drived 2,860 Kms on my first tank of fuel and still have plenty of fuel range. I charge i daily from my solar at work and have the dino juice for long trips. No more clogged EGR and it has a quick 0-100 in 5.7 secs. Looking forward to the plug in ranger next year, maybe it will be tempting me back :)
Wars is much much worst for environment compared to egr
...!!!
Can you just install a blank plate or it requires more than that?
I mean it’s must to make changes in ECU and tune after installation of blanking plate?
Yes, you have to reprog ecu after blanking egr or you will see a check in the dashboard.
Some blanking plates have a 7mm hole in them to let a bit of exhaust through to fool the computer .
depending on the model but the px1 is a full plate, px2 & 3 will need a 7mm hole to keep the sensors happy, will do a vid soon
