why petrol engines have more power than diesel engines of
same capacity?
Answer Posted / techyy
I am not sure about the relation with calorific value here, because even though calorific value of petrol is higher than diesel it's just by 4MJ/kg. And when we compare petrol and diesel engines of same capacity, diesel engines have longer strokes and hence bigger diameter crankshaft. This results in a diesel engine actually producing more torque than a petrol engine of same capacity.
Hence, as stated above, I feel it's just the relation between Torque, speed and power which results in a petrol engine generating more power than a diesel engine.
