Answer to Question #333075 in Mechanical Engineering for Trilok

Question

A single cylinder four stroke diesel engine running at 350 rpm develops. 26.5 kw brake power. The fuel contains 85% of carbon and 15% of hydrogen by weight. The mechanical and brake thermal efficiency may be taken as 86% and 30% respectively. The atmospheric air temperature is 20% and pressure is I bar. The engine uses 25% excess air and the volumetric efficiency is 82%. Determine the bore and stroke of engine if bore to stroke ratio is 1:2 and C.V. of fuel is 43960 kJ/kg of fuel
