Problem Diesel Cycle 9-59 A six-cylinder, four-stroke, 4.5-L compression-ignition engine operates on the ideal Diesel cycle with a compression ratio of 17. The air is at 95 kPa and 55°C at the beginning of the compression process and the engine speed is 2000 rpm. The engine uses light diesel fuel with a heating value of 42,500 kJ/kg, an air-fuel ratio of 24, and a combustion efficiency of 98 percent. Using constant specific heats at 850 K, determine: a) the maximum temperature in the cycle and the cutoff ratio, b) the net work output per cycle and the thermal efficiency, c) the mean effective pressure,
