Answer Posted / alankrit shukla
Firstly calorific value of petrol is greater than that of
diesel.
Secondly, ignition temperature of diesel is greater than
that of petrol,so for compression ignition process in diesel
engine high compression ratio(required pressure is about
50-60bar) is needed to ignite diesel hence much amount of
power is spent in compression process.
As a result petrol engines have more power than that of
diesel engines.
