A diesel engine is a type of internal combustion engine that uses compression ignition to turn energy in diesel fuel to rotary mechanical energy. A four-stroke (i = 0.5 for fourstroke engine, stroke = 150 mm and revolution = 2100 min1) diesel engine with 6 cylinders and an effective specific fuel consumption of 0.23 kg kW1h1 has an effective and indicated mean pressure of 9.2 bar and 6.8 bar, respectively, and a compression ratio of 17. The ambient temperature and pressure of the diesel engine is 30 and 1.017 bar, respectively, and the temperature of the exhaust gas is 650 . The clearance volume of the cylinder is 107.8 cm3, and the delivery ratio is 0.83. The mass flow rate of fuel for the diesel engine is 5.95 g s1. Taking the lower heating value of diesel fuel and specific heat of flue gas to be 42500 kJ kg1 and 1.08 kJ kg1K1, respectively, answer the following
