A.
Compression ratio of an Otto engine is comparatively higher than a diesel engine |
|
B.
Efficiency of an Otto engine is higher than that of a diesel engine for the same compression ratio |
|
C.
Otto engine efficiency decreases with the rise in compression ratio, due to decrease in work produced per quantity of heat |
|
D.
Diesel engine normally operates at lower compression ratio than an Otto engine for an equal output of work |
