A 6 cylinder 4.8 L, supercharged engine operating at 3500 rpm has an 9Voverall volumetric efficiency of 158 %. The supercharger has an isentropic efficiency of 92 % and a mechanical efficiency in its link with the engine of 87 %. It is desired that air be delived to the cylinders at 65 °C and 180 kPa, while ambient conditions are 23 °C and 98 kPa. 871.=2m Calculate 1. Amount of aftercooling needed (Answer: 5 kW) 2. Engine power lost to run supercharger (Answer: 18.4 kW) 10 of 15
