3- An in-line 6-cylinder engine with displacement volume of 3.3 liters burns diesel fuel with lower heating value of 42500 kJ/kg and equivalence ratio of 0.725. The compression ratio of the engine is 14 and the combustion efficiency is 100%. The cylinder conditions at the start of compression are 60°C and 101kPa. The cycle for this engine is an air-standard dual cycle in which half the fuel is burned at constant volume, and half at constant pressure. Calculate: a) Temperatures and pressures at each state of the cycle. b) Cutoff Ratio and Pressure Ratio c) Heat added during combustion d) Net indicated work e) Indicated thermal efficiency
