Question

I need help on answering these from the following question below:

1. you need to calculate the mass flow rate of air inducted to the engine

2. from your answer, in the question above, you need to determine the ratios of heat release in the flue gas and cooling water against input power for the engine

3. you need to discuss how emissions can be minimised with regards to the engine

The question:

A diesel engine is a type of internal combustion engine that uses compression ignitio 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 min⁻¹) diesel engine with 6 cylinders and an effective specific fuel consumption of 0.23 kg kW−1h−1 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 s−1. Taking the lower heating value of diesel fuel and specific heat of flue gas to be 42500 kJ kg−1 and 1.08 kJ kg−1K−1.
