When a three cylinder, four stroke cycle, SI engine operating at 4000 rpm is connected to an eddy current dynamometer, 70.4 kW of power is dissipated by the dynamometer. The engine has a total displacement volume of 2.4 liters and a mechanical efficiency of 82% at 4000rpm. Because of heat and mechanical losses, the dynamometer has an efficiency of 93%. Dynamo = (power recorded by the dynamo) / (actual break power from engine) Calculate (show your solution). a. Power lost to friction in engine b. Break mean effective pressure c. Engine torque at 4000rpm d. Engine specific volume
