Q3: A 4-stroke 6 litres engine is fuelled with methane (CH4) at an air-fuel ratio = 0.8. It operates at 2000
rpm with a volumetric efficiency of 80%. The exhaust (product) leaves the engine at 800 K, and the heat lost
to the coolant is 3.4×105 kJ/kmol. What is the engine's output power? Assume both air and fuel (methane)
inlet to the engine at 298 K. Take for methane, the molecular weight is M = 16 kg/kmol, and the heat of
combustion is 50.01 MJ/kg. The ambient conditions (p = 101 kPa, T = 25 °C).
