If your running your filters until the engine is getting "Starved for
Fuel", and "running lean", then your and absolute Moroooooon, (Bugs Bunny
Definition) as that would mean that there isn't enough fuel to fully
fill the Injectors each time they fire, AND that also means that there
would be NO fuel coming back thru the Fuel Return Line, AND consequently
No Cooling of the Injector Tips, which is the Primary Reason for the
Fuel Return Line, in the FIRST PLACE. Very Good way to BURN OUT the
Injector Tips on your CATs, Sonny.... Just where did you learn your
Diesel Engineering.... Dufus's R Us???


Huh? How the hell do you get it to idle?? The intake is either naturally
aspirated or supercharged (4-stroke) and you STARVE IT OF FUEL TO MAKE IT
SLOW DOWN! It's nearly starved to death at idle with just enough fire to
turn it over....

?????/ I'm not sure about your engine, but my engines regulate FUEL
SUPPLY when I press down on the pedal or push the throttles forward...or
aft. What kinda cooling does the injector tip require when there's so
little fuel in ALL THAT COOL AIR the damned thing hardly fires at all?!

You musta missed something. A diesel engine is one of the simplest
machines ever built.

See all the fire left over from this one running SO LEAN AT SLOW SPEED?
You're looking right into the combustion chamber of a running ship engine.
See any smoke?? Nope.

It's so hot in there lube oil is dripping off all over the place....

Duhhh...
