Or are you saying that some engines injected fuel into cool air during
the induction stroke, then compressed the fuel-and-air mixture (as

compressed to a high enough temperature? Didn't that make the timing of
combustion extremely variable, without any control over the duration of
combustion, whereas injection into the pre-heated air allows a long
period of injection to give prolonged burn.


yes,. yes and yes, which is why it aint used much these days - i've only seen it on tractors

******* to start - we ended up throwing a diesel soaked rag into the manifold and lighting it. Once started we closed up the manifold after removing rag



Gloplug was ineffective
