Four stroke diesel engine uses which cycle for its operation
-
petrol cycle
-
diesel cycle
-
Castor cycle
-
jatropha cycle
B
Correct answer
Explanation
A four-stroke diesel engine operates on the Diesel cycle, which is characterized by constant pressure combustion (heat addition at constant pressure). Unlike the Otto cycle used in petrol engines, diesel engines compress air alone and then inject fuel which ignites spontaneously. Castor and jatropha cycles are not valid thermodynamic cycles.
