The indicated efficiency is 67%of the corresponding ideal-air-standard Otto cycle of two-stroke SI engine with a compression ratio of 8:1 At 7590rpm, mechanical efficiency is 83.2%, and the volumetric efficiency of 88.4%. The air-fuel ratio (gravimetric, that is by mass) is 12:1 and the calorific value of the fuel is 42 MJ/kg. It has a swept volume of 756 cm³. The air is inducted at 71.5°F and 750.1ltorr. Determine the overall efficiency and brake specific fuel consumption.
