1. A diesel engine produces 500 kW at 3800 rpm while consuming 0.02975 kg/s of fue During operation, data shows that its mechanical energy loses 17%, the actual volum of air going into each cylinder is 90% (The volumetric efficiency has a negligibl variation) and the actual fuel to air ratio is 0.05. If the ambient temperature at th location is 18 °C and the standard atmospheric condition is 14 °C hotter with pressure 100 kPa, what are the standard parameters of the engine: a) Brake Power, kW

1. A diesel engine produces 500 kW at 3800 rpm while consuming 0.02975 kg/s of fuel. During operation, data shows that its mechanical energy loses 17%, the actual volume of air going into each cylinder is 90% (The volumetric efficiency has a negligible variation) and the actual fuel to air ratio is 0.05. If the ambient temperature at this location is 18 °C and the standard atmospheric condition is 14 °C hotter with pressure of 100 kPa, what are the standard parameters of the engine: a) Brake Power, kW b) Indicated Specific Fuel Consumption, kg/kW-hr c) Mass of air, kg/s d) Indicated Mean Effective Pressure, kPa
