B. Diesel engines
C. Multi cylinder engines
D. All of these
I think this should 30 to 35
30%-35%
This is error in question it's insicated tharmal efficiency
The thermal efficiency of diesel engine is up to 40%
52% max.
Thermal efficiency of diesel engine is 30%
32- 38%
I think it's wrong diesel efficiency 30..35%
Option C can be justifiable as the largest diesel engine in the world peaks around 51%. Normally a diesel engine has higher efficiency than the petrol engine and it will be ranging between 30-35%.
