Artie Clapham Liebherr is the worst for that.

[@Porty1119]

@@MitzvosGolem1 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.

[@84gssteve]

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.

[@cedricrummell5986]

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.

[@kimpatz2189]

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.

[@guyconnell2250]

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.

[@ft3qfDaffe3]

VERY INFORMATIVE, I grasped a better consept of the HEUI system

[@montananative2414]

[@markdavis8888]

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.

[@BruceCarbonLakeriver]

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

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.

[@donaldhollums3278]

A very educational film, I’m subscribed. I have better understanding and have done more work on gasoline engines. I’m trying to increase my understanding of Diesel engines; everything I know about them would barely fill the bottom of a thimble. I don’t know how I can begin to try and repair or service Diesel engines because I’m employed full time in another line of work and lack the time and funds to get to an “institute”. I have followed Clay Koon on his channel since he works on the “Large Cars”, I know he doesn’t have the time to get into this kind of detail though.

Your mechanical Truck engine, Cat fuel systems was Forged Body(very old and used on early 1693) , Compact Scroll (used on a A model in a truck, 1600 series and 1100 series, early 3300 series) Starting with 3406 B New Scroll fuel system (had two slightly different VTU starting in the 4MG's .Early 4MG's had old 7FB VTU) 3208's and early 3306's used a sleeve metering fuel system. It ran in diesel fuel and air in the fuel was a problem. As I have said before, a good mechanical Cat pump tech can look up and rerate a mechanical engine. Not hook ET up and just flash it like you do today.

[@skylinefever]

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.

[@electric7487]

I don't see how non-common rail engine can't have active DPF regeneration.

[@chefmatthammerschmidt8408]

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.
