[Vwdiesel] Brakes --- engine brakes -- ( Hagars point of observation)

Dana asked :

Does the Bosch pump inject more fuel as rpm increases but no additional 
fuel is being called for beyond what is needed for the idle?

answer:    Yes indeed ------ depending on where the idle is set. Pedal only
controls governor   ---   As a matter of fact it is a real skill to be able to set
the idle where engine does not shake -- and engine does not run away as
RPM is increased. Try it by increasing the idle. Be ready on the key. Or just
slow her down with a bit of load.

The physics behind the drag from the engine is much like that of an air 
compressor. Heat is dissipated by coolant.                                               Hagar.
