The thermal efficiency of diesel engines is about
Answer: Option
Explanation:
The thermal efficiency of diesel engines is about 30-50%. This means that for every 100 units of fuel energy input, the engine is able to convert 30-50 units of that energy into useful work. The remaining energy is lost as heat or exhaust.
The maximum theoretical efficiency of a diesel engine is about 70%. However, this is rarely achieved in practice due to factors such as friction, heat loss, and incomplete combustion.

The thermal efficiency of the diesel engine varies from 40 to 50 per cent and in petrol 25 to 30 percentage.
