A four-cylinders, 1398 cm", CI engine operating on the air standard diesel cycle has cylinder conditions at the start of compression of 66 C and 150 kPa. The engine runs at 2600 rpm. The compression ratio is 20, the air-to-fuel ratio is 22, the combustion efficiency is 98%, and the fuel heating value is 42500 kJ/kg. Assume 3% exhaust residual and exhaust pressure of 100 kPa, then calculate 1. The pressure, temperature and volume at each state of the cycle. 2. Net power, rate of heat added and thermal efficiency. 3. Actual exhaust residual, Xr. 4. Brake power in (kW) 5. Turque in (N.m) 6. Friction power in (kW) 7. Brake mean effective pressure 8.
