A four cylinder engine running on theottocycle at 3000 rpm and with a compression ratio of 10:1 has a peak cylinder temperature of 3500 k and a inlet conditions of 300 k and 1 bar. The cylinder is 70mm indiameter with a stroke length of 65 mm and has a mechanicalefficiencyof85%. Thecalorific value of the fuel in 45Mj/kg. Given these conditions and assumingisentropiccompression and expansion,determine:

Part A - The mass flow rate of the air into the engine. (Note that includes all of the cylinders)

Part B - The mass flow rate of the fuel into the engine.

Part C - The power output at the wheels

Part D - The efficiency of the cycle
