. A twin-cylinder 2-stroke engine has a swept volume of 150 cm3 . The maximum power output is 19 kW at 11,000 rpm. At this condition, the bsfc is .11kg/MJ and the gravimetric air/fuel ratio is 12:1. If ambient test conditions are 10 C, 1.03 bar and the fuel has a calorific value of 44 MJ/kg, calculate the bmep, the arbitrary overall efficiency and the volumetric efficiency.
