Can someone explain the basic function of the Mechanical Injection?
I am sticking to the mechanical injection on the 220 SEB, and would like to know the basics.
I understand there is;
1. Fuel pump at the back (can the more modern Bosch pumps be used that are found on the K-Jetronic?),
2. Mechanical gear driven pump (how does it adjust, just to rpm, or also throttle position? Does vacuum play a role?
3. Fuel lines from the mech. pump to the injectors
and thats it?
How does it manage cold start? Seperate injector?
