Hello,
I have been interested on fi for the past few years and have always been reading on tuning afr. One thing i am a bit cloudy on, but somewhat understand is why diesels take on a turbo so easily?
Diesels are easily double the cr of a na gas engine, so one would think that there would be detonation or pre ignition. If you put a turbo on a gas engine its a ticking timebomb without a tune, where as a diesel is more forgiving.
Before really owning a diesel i thought the answer was simple: a gasser has more of an explosion due the the volitality of gas while a diesel would be more or a burn, which is completely opposite (in the sense that diesels boom and gassers burn).
I have come to the conclusion that with a high cr, these diesels are designed for extreme preasures whethor it be construction of the engine or make of the internals. (Which i assume are forged agross the board ). Lastly and arguably most important is fuel in a diesel only enters the combustion chamber when it should be fired, where a gas engine has fuel that. An theoretically preignite during intake and compression stroke, yielding a big explosion.
Anyways i know i have thought about it, so others must have had the question . Did i hit the nail on the head or am i missing/incorrect?
