Compression ratio of an Otto engine is comparatively higher than a diesel engine

Efficiency of an Otto engine is higher than that of a diesel engine for the same compression ratio

Otto engine efficiency decreases with the rise in compression ratio, due to decrease in work produced per quantity of heat

Diesel engine normally operates at lower compression ratio than an Otto engine for an equal output of work
