@@Nudnik1 Liebherr sells garbage with a fancy name on it. A company I used to work for had a Liebherr dragline at a rock mine in Arizona. The thing went down; Liebherr sent the wrong parts from Germany even though they'd received photos of the parts in question, as well as part numbers and descriptions. There was several months of back-and-forth between Liebherr and the mine operator until the thing finally got fixed. They also had the transmission on a Liebherr loader catch fire(!). Absolute trash, I'd rather have a Komatsu and that's saying something.
I'm in college to become a diesel mechanic and my teacher uses your videos in class. Please keep doing these, they are very well informative and well done
@@bartholomausallen883 he's probably from the uk, in the uk highschool is only up until year 10 or 10th grade and after that 11th and 12th grade (year 11 and 12) is what they call college and university is what most call college.
I have no experience as a mechanic, just interested in gaining a very basic understanding of how these engine systems work. I’ve been watching a lot of your content lately and truly appreciate you putting these videos out.
Manage lawn care at a cemetery. Never had any experience with this stuff before. Trying to learn so I don't sound so stupid when things break down. Thank you for these videos.
Yes, Love the mechanical injection for longevity/ simplicity (maritime use) couldn't you just have a spare mechanical injection unit/ if your running engine 24/7 in the middle of the OCEAN... If that was even the problem? And cost $10k - $20k and up??? Roughly Thank you "Love the videos "
Great info. Another sort of hybrid is the in-block unit injection pump system used on many smaller Deutz and Isuzu engines like the FM/FL 1011 and 2011. Basically an individual cam-operated injection pump at each cylinder, each feeding a single in-head nozzle. It still uses a common rack for all the pumps, but since the whole thing is laid out along the length of the engine, it makes for plenty of room to work on an individual cylinder system and all the injection lines are straight and equal length.
You are absolutely correct on everything. I have worked on all the fuel systems you discussed to include fuel bench for 30+ years, finally retired working part time as a technical instructor specializing in T4F. Good to see the good work and no BS information you're passing on! ( Forged body fuel system D399$#%@)
I will never probably fix a Caterpillar engine...but knowledge is power and it is all relevant to what I like to do on my much smaller and basic diesel engines.
As a fire dept., we hire everyone from engineers to ditch diggers. This is a great video I can share to get everyone to notice the parts and problems with a general component of the rig. Thanks.
The 3306 is a totally amazing engine - I had them in loaders - dozers - compactors - NEVER had a serious fuel pump problem. Start in a few spins (summertime or well heated) ran like a beast.
Don't forget the CAPS fuel system (Cummins Accumulator Pump System) found on Cummins ISC 8.3L and 8.9L used in on-road, industrial and just about everything in between.
Love all your videos. I was always partial to the electronic unit injectors they seemed to last the longest. I have been in the diesel mechanic industry for 15 years (working on all varieties of engines) and I find your videos very informative keep it up.
Great video as always. One thing I was kinda surprised I didn’t see, although it could be because Caterpillar doesn’t use them to my knowledge, was the distributor style injection pumps like those made by Stanadyne. In my area it’s very easy to find those pumps on old-ish tractors and construction equipment. Like I said though, I don’t think Cat ever used them because I think they made all their own fuel pumps. Still a really great video and very informative.
Its called rotary pump injector. Infamous for these type of injectors are the high revving 4JB1 from Isuzu on the Trooper. These injectors pumps are built for high revving. Its like a hydraulic pump design.
I went to school for diesel technology but learned more in the field. My instructor was a old grumpy man he had no business being a teacher. Glad I went got my cdl and make more money than wrenching on trucks
Very nice. I’m always excited for new videos when posted. Keep it up. I don’t have time for mechanics school so these videos really help us layman. Keep up the good work Josh.
I think its so important to make videos discussing several systems in the engine,as it aids for a better understanding,and for adequate selection of the proper engine that satisfies the need,but i think it would be fine to include various types of control systems that governs the engine and the generator and their limitations,thankyou
My understanding was high sulphur fuel was better for common rails as it had better lubricity than low sulphur fuels. Especially when running high pressure.
Great video explaining how various fuel systems work. I enjoyed this video and would appreciate more educational videos. Thank you for sharing your knowledge.
The old 2cycle Detroit Diesels were interesting where they used cam operated injectors , but the governors appeared complex . Maybe not so bad , once you took enough apart though . They could handle very old fuel . Not as efficient as 4 cycle diesels back in the 40s , 50s ,60s and 70s , but better than gas engines . Nice video!
wish this content was around back when i had a boat with a pair of 3208TAs,could have really used this kind of information....great channel...keep up the good work
Here in Costa Rica we see Cummins big cam,88 series,magnum... Some of them are PT I think They are still running and fairly cheap to maintain but not the best at fuel consumption Exempt for the 88 series 315hp those are great in my opinion
Cummins PT system..............simple,reliable,good performance,cheap to fix.The K-19 Cummins could crush anything else in performance and fuel economy, even the Electronic engines that came later. The mechanical inline pumps used by Cat,Mack etc were in their day deadly expensive to fix. I can remember in the 1990's that AUD $10,000 was not unusual for a pump rebuild. Even a small light vehicle like a Nissan Patrol or Toyota landcruiser was $2500 to $3500 to fix.
4:10 up until the late 1980s, Benz also had an emergency engine shutoff device under the hood, just in case an electrical device doesn't function correctly. 6:22 Many other computerized diesels had inline or distributor fuel pumps, but the mechanical governers were replaced with electrical components. The most common example I can think of is a 1998-2002 Dodge Cummins 24V. 7:40 VW had something similar to that, and they called it "PD" or "Pump Duse." It means "Pump in head." 9:18 Those were also found on the Ford Powerstroke 7.3 and 6.0. 13:32 In addition, I think common rail injection is the only way a DPF could go through active regen. I know that when the 6.0 PSD was replaced with the 6.4 PSD, the 6.4 got both common rail injection and a DPF. 14:50 I have been told that it would be best to put performance additives in the fuel tank.
Love your channel Sir, these videos help out like no there!!! I’m currently going to school to become a diesel tech. What are some words of advice/pointers you would give to a noobie??
I have driven all of the ones mentioned, not necessarily Cat, but in one form or another. I will always have as my favorite the mechanical Cat, direct injection system. When those came out around 1979 or so, they ruled the highway. The 3406B 425 was/is my favorite of all. I enjoyed the "precup" motors to drive also, but they got poor fuel economy compared to the direct injection motors. As you said, everybody has gone to common rail now, mainly for emissions reasons.
Thank in this video, knocked, injectors electronics, injection pump, this is add my knowledge, and additional my personal experience. Thank you bro.! God bless!
My personal favorite were idi systems, simple and could run on just about anything. I work on a lot of heui systems since no one in my area seems to, I'm also doing a lot of 6.7 power strokes these days
Sitting in a 90's TDI and love the system. It has the central high preasure fuel pump which provides the nozzles with diesel. Those nozzles are controlled by the fuel preassure which gets applied. Means the setting of the fuel pump gives the timing of ignition/injection. The gouvenor can (electronical) adjust the ignition timing in dependency of load and state of the engine. But it just can inject once per working stroke. I felt like it is very robust although the fuel pump (comparable with the hue (or hooie?!) system) with the difference that the oil preassure isn't used for the nozzles anyhow. Which gives actually an incredible (even extremly) cold startup behaviour. An additional sensor gives the ICU the position of the needles of the nozzles for the adjusting cycle. In my case it is a 66kW 1.9 TDI built 1993 which is boosted by a turbo charger and the engine has an very high compression ratio of 19,5 to 1. (for the US guys it is a 4 cylinder engine with 86,8cu) :D Even it is very cold (I'm living in the Alps in Europe where we can get -20°C) it merely needs the glow plug cycle and works well with SAE 10W40. Great Channel, subbed and liked! Happy driving !!! :D
Great job - but - you needed to say - engine lube oil - on the firing of HEUI system and diesel oil on the fuel side. I did learn more about fuel systems - thanks.
The new development is the Ducted Fuel Injection. Developing at Sandia National Laboratory and based on the bunsen burner this injection system will eliminate soot. The complete mixing of air and fuel is the key. This will be able to be retro fitted in existing diesels. This is so important with all the existing diesel engines like ships, trains, equipment and trucks. There is also Renewable diesel coming your way. This is not bio diesel but refined from the same feed stock. Renewable diesel is better than petroleum diesel in every measure. Diesel is not dead.
I'm old school diesel trained but have more or less caught up with the new stuff and tbh I like the advantages of the newer systems, more power torque quieter etc etc but yes , in a way youre right and I could diagnose problems on the phone on the old gear but without a decent bi-di scan tool you have no clue, it could be anything....
@@turtlezed Ive got some old equipment frm the 70s and 80s that is all turn key and ready to go and i just can't believe that new electronics will be ready to run the same as it did brand new 30 yrs frm now. Its like 60s and 70s muscle cars there just wont be anything to replace them someday.
If they hadn't allowed the proliferation of diesel engined passenger cars, I wonder if we would be in this position right now...in the UK people are turning away from diesel passenger cars as sales have plummeted. The sheer cost of repairing a modern diesel is outweighing any savings made by the engines frugality. The most modern diesels have sophisticated treatment systems and when they go wrong, they go wrong big time. Anybody asking me these days, I say depending on your mileage and usage I would go with a modern petrol engine and if you want more mpg, spend the extra and get it LPG converted.they are way simpler( in engineering terms) to diagnose and work on.
@@turtlezed Modern emissions systems do more harm than good. I run 70s and 80s Deutz diesels with water scrubbers - for mine/industrial use, the scrubbers are great and cut DPM by about 30%.
About that mechanical fuel system in the early diesel engines with caterpillar, Iowa definitely tend to say that that is extremely complicated without lot that can go wrong. I really do find it amazing that apart that could cost as little as I don't know $0.40 totally destroy any engine regardless of fuel type. It is totally a work of art being a mechanic and improving upon designs in the process. The big block V8 made by Chevy extremely easy to Shaw's make big Power with them I'd be doing that very reliably. And yes I do understand that you have to find the right part for that particular system that you are upgrading no matter whether it's gasoline diesel propane compressed natural gas I could list about three or four other fuel Types on top of that but those are just outright completely uncommon and a rarity to find. I really do appreciate this video because there really is a very high level of artwork to a video like this in the way that you conveyed your message so clearly. you really are like me you have your own totally Unique Style. Thank you so much one mechanic to another man thank you your videos are phenomenal and very helpful resources.
Great vid. I work for a Cat dealer in Canada. Not Toromont, the bigger one, lol. Mainly G3600 and G3500, natural gas compression and EP and driven equipment. I like your vids, sometimes to much like work, to me haha. Keep em’ up. Always great refresher for my diesel days. Cheers
to shut off a mechanical injected engine sometimes it doesnt have an electronic shutdown. you have to pull the rack to shutdown The old cat machines by lifting the throttle pedal upwards
40 years as a mechanic. Marine industrial . Love this guy. Best channel. CAT should sponsor his channel.
In a way... they already do. LOL
They don't want anyone knowing how to fix cat stuff. They will loose out as they want people to take to the dealerships to fix.
