my friend the question u have asked is not complete .A petrol and diesel engine should be compared for a given parameter ,other wise how we can compare?.any way I am assuming that for same capacity.suppose consider a 1000CC petrol and diesel engine.Usually petrol will have more power becz,petrol engine produces more heat at the combustion chamber as petrol having more calorific value .moreover heat losses will be more in the cases of diesel engine than petrol engine such as compresion losses,turbulent loses,exhaust loses...Any way even though the compression ratio is high for diesel engine it wont contribute to increased power ,but an increased torque,thats why diesel engines have high torque than petrol engines for same capacity,still dobt existing mail me at bala300587@gmail.com
