A diesel eight cylinder four-stroke engine has a 200mm bore and
200mm stroke. At its optimum operating point, it has a
brake-specific fuel consumption of 245 g/kWh at an engine speed of
2000 rpm. The engine’s volumetric efficiency is 0.85, air-fuel
ratio 15:1, and inlet air density is 1.2 kg/m3 . What is the power
output and brake mean effective pressure of the engine?
