WebDiesel engines. Diesel engines use higher compression ratios than petrol engines, because the lack of a spark plug means that the compression ratio must increase the temperature of the air in the cylinder sufficiently … WebIf the engine compression was 30:1 or something absurdly high, the vaporized diesel would combust well before the piston reaches full compression. It seems like there would be substantial engine damage. The sudden increase in pressure on the piston (from premature detonation) would likely put a lot of stress (torque) on the crankshaft. the prestige restaurant
