A company based in Potchefstroom decided to buy a 17 kW, 4-stroke, 4-cylinder diesel engine generator to make provision during loadshedding. The compression ratio is 14 and the temperature after adiabatic expansion (before the exhaust valve opens) is 500°C. The average speed of the engine is 1500 rpm. Atmospheric conditions are at 20°C and 87 kPa. Assume an air-standard diesel cycle and that air is an ideal gas. The specific heats for air are constant.
a) Determine the specific heat in and out of this cycle?
b) Determine the specific work during compression, combustion, and expansion?
c) Calculate the cycle efficiency?
d) What is the volume (ml) of each cylinder in this generator?
