Consider an ideal 4-stroke Diesel engine cycle. Air is compressed isentropically and combustion is modelled as an isobaric heat addition. The gas then expands isentropically and the exhaust/intake strokes are modelled as a single isochoric heat rejection process. Air enters the engine at temperature 311 kand 1.013 bar. The compression ratio is r=9.4 and cut-off ratio re- 3.5. Estimate the heat added during combustion per kilogram of air. Give your answer in k/kg to the nearest whole number. For air Co-1.005 k/kgk and cy - 0.718 k/kgK.
