Assertion (A): In practice, the efficiency of diesel engine is higher than that of petrol engines
Reason (R): For the same compression ratio, the efficiency of diesel cycle is higher than that of Otto cycle.
Option (A)
Both A and R are individually true and R is the correct explanation of A
Option (B)
Both A and R are true but R is not the correct explanation A
A is true but R is false
A is false but R is true
Correct Option:
Question Solution:
For same compression ratio otto cycle is more efficient and produces more work than diesel cycle
