How a VE pump works

[jimfoo]

This site covers the entire workings of a VE pump very well. Some pictures are missing, but all the important ones are there.

Good find!

An addition not explained on that page is the unit in place of the timing advance cover on some pumps that has one steel line and one terminal. It is called the ALFB, or the "load sensitive start of delivery with deactivation feature". It reacts to declining loads(from full load to part throttle) at constant control lever positions by retarding the timing. It advances the timing with rising loads. It is supposed to provide "smoother engine operation" and cleaner emissions at part throttle and idle. The terminal is to deactivate it to reduce HC when the engine is cold(<60*C) when energized.
Now no one has to wonder any more. :wink:  Can you tell I got a Bosch pump book today? :lol:  :lol:

This is the one I got. There are other sellers as well. It's like the book Tintin provided a link to in the French section, but obviously it's in English. It covers mechanical and electronic pumps.

this type of information is exactly what i was looking for, i posted under GENERAL in this forum without checking out FAQ/ Tech Tips first

diesel newb like myself appreciates this very much, i can't overemphasize the importance of having a solid understanding of the BASICS first. even though some of the pics are missing, this is plenty enough to get me started.

muchos gracias senyor jimfoo.

I can't get the site to respond, these posts aren't very old, is anyone else having trouble?

haha, I was just reading thru the FAQ and came across this.  He was my teacher through a lot of my classes at Canton tech in upstate NY.  super space cadet, but boy does he know his stuff.  He left the college after my senior year to take some high up job for Lexus to train the guys who go out and train techs/stuff like that.  I still have his book that all this came out of.  was kind of intimidating taking a class from the guy who wrote the book you're using.  Its awesome; 13 years later, and I still enjoy browsing through it. 
here's to you ed.......wherever you are....
