Reference no: EM13868562

A 2.5 liter four stroke naturally aspirated direct injection diesel engine is designed to run at 4500rpm with a power output of 45kW; the volumetric efficiency is found to be 80%. The bsfc is 0.071 kg/MJ, and the fuel has a calorific value of 42 MJ/kg. The ambient conditions for the test were 20 deg. C (68 deg. F) and 1 bar. Calculate the bmep, the overall efficiency, and the air-fuel ration.
