Question
Question 9 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 isochonic heat rejection process Air enters the engine at temperature 316 k and 1.013 bar. The compression ratio is r= 12.1 and cut-off ratio re=3.3. Estimate the heat added during combustion per kilogram of air. Give your answer in kl/kg to the nearest whole number. For air o-1.005 k/kgK and cy 0.718 k/kgk.
