Yeah, i agree that the terminology is a bit skewed. after all, the cylinder is must only travel up and down twice per combustion sequence.Originally Posted by jboy
if this engine was running in a forced induction, i would be worried that without proper downtuning of the turbo/super charger, you would run the risk of over feeding the engine. also, the problem of detination would further increased due to the momentary pause at the top of the compression cycle. normally aspirated engines run the timing such that the igntion spark occurs slightly before TDC on the compression stroke. when you add forced induction, be it turbo or supercharger, you have to retard the timing so that you dont detonate the mixture in the split second before complete compression occurs. this means that the ignition would have to occur before TDC... negating a huge purpose of this engine... ignition AFTER the piston has stopped at TDC.
now, from just a "get the most fuel in a possible" position. yes, i think that a turbo or super charger would be nice on this engine, given the fact that the entire cylinder would be able to be pressurized to the full boost ammount of the FI equipment.
however, you would have to take a look at the overall effect of adding boost to an engine like this. what are the tradeoffs, and how much does the added performance detract from the gains in technology.
Anyone with other thoughts... prove me wrong... anything.
