QUESTION 2 The combustion in a Diesel cycle is 82% efficient and 17% of the heat of combustion is lost during combustion. Assume constant specific heats $c_v = 0.718 \text{ kJ/kgK}$ and $c_p = 1.005 \text{ kJ/kgK}$. If the heating value of diesel fuel is 43,159 kJ/kg of fuel, What is the air fuel ratio (AF) if the temperatures before and after combustion are 559 K and 1,761 K?
