OK Folks think about it, 4 stroke in reverse. That means sucking air in
via the exhoust, adding gas to it, hope-to-gosh that the glowing
carbon deposits ingite the air/???? mixture, then sprays it thru the
intake valve, past the venturi in the carb, and out thru the air
cleaner.
After-run (dieseling) cannot happen in electronic fuel injection
because when you turn off the key/fuel, ?????? burns?
It can happen in a carb. type engine, because it will keep sucking air
past the venturi, mixing it in the intake manifold, and the hot
deposits in the cylinder ingites it. but not in reverse. no fuel.
get your money back from that ASE class. (well maybe it could
happen if you pre-charged 90 feet of exuest pipe with nice air fuel
mix....

>Sam,
4 stroke engines can and do run backwards, but not very well. Have you
ever seen
a car continue to run after the ignition was turned off? 50 to 60
percent of the
time, the engine is running bacwards, ignited by a hot spot in the
chamber due to
an overheated and poorly tuned engine. I had an ASE class on this.
