I have asked this question for several years, and i was thinking for rack position only but it was with helix in combination for meterd quantity at start.
I've been around MACK TRUCKS since the thermodyne an the maxidyne so can somebody explain it to me what is the difference between the Robert Bosch injection pumps and the American Bosch injection pumps.
@J M Here are some information to answer your question. With German Bosch Diesel fuel injection products, when they say P- they are talking about the size or the model of the injection pump. A few examples of injection pump with different sizes: M-size pump- 7mm plunger stroke, A-size pump- 8mm plunger stroke, B-size pump- 10mm plunger stroke, and P-size pump- also with 10mm plunger stroke. I also included some technical details for further distinction. All the best and stay safe and away from covid.
How does such an engine advance its timing, under light load or high speed? Like old-fashioned petrol engines, using vacuum or centrifugal advance. I can't see any way to do it. The injector camshaft is fixed.
@@CrazyForCooCooPuffsnot all mechanical injection pumps don’t have timing advance, for example the Bosch VE pump has a timing advance piston that advances the timing as the revs increase
Love these type of videos very useful and informative. Only wish that they would remake them with more modern animations to make it easier to visualize the concepts. I understand this means that it would take 💰.
As Robert said, there are regulations for emissions and fuel economy that these older pumps cannot achieve. Modern pumps like the CP4 might not be as rugged or long-lasting, but they are lighter, more responsive and far more fuel efficient. Everything is a trade-off, in-line pumps have pros and cons, as do modern CR pumps.

شكراً جزيلاً، من اليمن 🇾🇪
Thank you for posting this!I love learning about these injection pumps.
Thank you for preserving this gem
These Bosch injection pump videos help me out alot. Thanks!
I'm enjoying these films immensely!

excelente video muchísimas gracias por publicar sería mucho pedir que alguien los hiciera en español
Thank you from 🇳🇬

Great video. thanks for sharing!
I feel like I took a walk back to the 60s.
Anyone know what the "P" stands for. I'm thinking piston or something thereabouts but would like to know for sure even if it's in German

Way of teaching is very good god bless you. love from India
India, the home of the very famous brand of diesel fuel injection pumps, injectors and other fuel systems accessories, MICO!!!

It doesn't its a mechanical injection, it only ever injects a set specified time, the common rail ones can change injection timing.
@@CrazyForCooCooPuffs this is wroing
@Reno's Garage no I'm not, telling me I'm wr9ng with out a reason doesn't help.

Where can you get a v8 pump
Mack used them on the old 325 thermodyne v8’s, and I think some on some of the newer ones as well like the 866’s.
V8 pumps are probably used on V8 diesel engines
@@j.m.5995 no shit..... ya dont say!!...
@@americantruck3943 That's right I said it
I just bought one from a 9.0L international.
I'll be here from deboss garage
Vvv nice wark
Is the direction of rotation mentioned from 9.32 correct.
Bcoz it contradict with what said earlier
no, it is correct. It threw me at first too, but you're not turning the plunger, you're turning the barrell

Thanx, very useful
All this, before they were famous...
Inline pump setting video need
Estudio eso
Why cant bosch continue making pumps like this instead of the junk ass cp4 pumps
They still do. It’s the government requiring their customers to achieve certain goals that a mechanical pump can not deliver.
