A diesel engine working on the dual combustion cycle takes in air at 95kPa, 25°C and has a maximum cycle pressure of 6600kPa. The compression ratio is 15:1. Assuming that the heats supplied at constant volume and pressure are equal, calculate the thermal efficiency. Take the compression and expansion processes as adiabatic and c and Cp for air as 0.718kJ/kgK and 1.005kJ/kgK respectively.
