A single cylinder petrol engine, operates on two stroke cycle,the bore of each cyclinder is 90 mm, and the stroke is 120 mm, theclearence volume of the cylinder is 60 cc, at the speed of 5000 rpmand the fuel consumption is 7.5 gm/s, the load applied on the brakedrum is is 65 kg, and the radius of the drum with rope is 0.48 m.Calculate your brake power and indicated power if mechanicalefficiency is 80%. Also find the brake thermal efficency, thecalorific value is 34000 kJ/kg, indicated mean effective pressure.The relative efficiency, assuming the engine works at constantvolume cycle, and gama is 1.4.
