A 4-stroke diesel engine is to be designed to operate with the following characteristics at sea level, where the ambient conditions are 103 kPa and 10C. b.p=260 kW, s.f.c=0.244 kg/kW.h, Speed = 1500 rpm, volumetric efficiency = 0.78, A/F ratio = 17:1. Calculate the required engine capacity and the anticipated bmep. The engine is fitted with a supercharger so that it may be operated at an altitude of 2700 m where the atmospheric pressure is 73 kPa. The power taken by the supercharger is 8% of the total power produced by the engine and the temperature of the air leaving the supercharger is 32C. The A/F ratio and thermal efficiency remain the same, so as the nv Calculate the increase of pressure at the supercharger to maintain the same net power output. Take R = 0.287 kJ/kg.K.
