Course: Power Plant Question: 5 In some application V-8 four stroke petrol engine is needed to produce 190 kW at 4420 rpm. At the given engine speed the air-fuel ratio (A/F) is 15/1 and the volumetric efficiency is 70 percent. Also at the compression ratio of 10/1, the brake thermal efficiency is considered to be 35%. The calorific value of the fuel used is 44200 kJ/kg and the free air conditions are 1 bar and 15 0C. The bore to stroke ratio (B/S) is 0.8 for the engine. Solve the problem to find the following: a. Engine displacement b. Size of the bore c. Size of the stroke
