[quote=PierrePHRWEAUX;3312]Actually, the main difference is that the carnot cycle (gasoline engine) has a theoretical efficiency of 37% and the diesel cycle 42% (So just 5% gap in efficiency)....quote]
would not the difference in efficiency be better conceptualized as 13.5%(42/37) in the sense that this ratio would translate to perhaps a comparabe fuel-efficiency ratio?
