Question
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).
i) Determine all the working temperatures and pressures at all points on a P – V
diagram.
ii) Calculate the thermal efficiency of the cycle.
i) If the engine is planning to operate at 3000 rpm, evaluate the power rating produce
by the engine.
iv) Evaluate thermal efficiency of this cycle with respect to thermal efficiency of
Carnot cycle. Explain your answer.
