Only on the ground, after engine shut-down

Question 38

Diesel Engine...

Answer 38

- Have a higher compression ratio. - Intake system is never heated because diesel engine is an injection engine. - produce less maximum power output. - There is no mixture control. - The amount of power is determined by the fuel flow only. - Thermal efficiency is higher than that for a petrol engine.
