b) If one mole of air (rigid diatomic gas) is initially at 20 °C, is compressed and expanded 7- fold as part of the Diesel cycle, and 4 kJ of heat is generated as a result of the fuel injection and combustion, calculate: (i) the temperature after each stage of the Diesel cycle; (ii) the heat absorbed/expelled during each stage of the cycle; and (iii) the efficiency of the Diesel cycle.
