A Diesel engine has a swept volume of 2 liters operates on the four-stroke cycle. When this engine is installed in a car, the operating point for a speed of 120 km/h corresponds to a torque of 72 Nm at an engine rotational speed of 3670 rpm. At these conditions the value of the bsfc is found equal to 300 g/kW.h. The fuel has a heat value of 43 MJ/kg. The ambient conditions are 1.05 bar for pressure and 27 °C for temperature. The fuel density is 795 kg/m³. Calculate the : 1. bmep, 2. Overall efficiency, 3. Fuel consumption (liters/100 km). 4. Volumetric efficiency, if the gravimetric AF ratio is 20.
