Question

(a) Diesel engines had been originally developed to create an isothermal combustion process in a cylinder, to eliminate the heat transfer irreversibilities and thus approach the Carnot cycle thermal efficiency. You as a researcher have been appointed to evaluate a diesel engine which has four-cylinder, four-stroke and 3 liters of displacement volume with a compression ratio of 17. The engine uses biodiesel fuel with a heating value of 42,500 kJ/kg and an air-fuel ratio of 24. You are required to evaluate the engine characteristics (Assume constant specific heat at 500 K).
