A spark ignition (S.I.), 4-stroke engine, of a 57 mm bore and 58.7 mm stroke, with a compression ratio of 10.4:1 was installed on a 120 kg motorcycle chassis. During cruising at 90 km/h, this motorcycle can achieve 2.6 litres/100 km fuel economy with an average volumetric efficiency of 75%. Using appropriate assumptions, sketch the P-v diagram of the engine's operating cycle and calculate; i) the engine's clearance volume; ii) the motorcycle potential acceleration, if the total mass of the motorcycle and its rider is given at 180 kg and the rider took 13 seconds to reach 60 km/h; and the amount of energy loss due to the loss in the volumetric efficiency.
