Sentropic compression sochoric heat addition sentropic expansion Isobaric heat rejection P-V plot of the Atkinson cycle is shown below: P 2 4 1 Note that the expansion stroke (VA) is longer than the compression stroke. If the compression ratio is 8.7 and the expansion ratio is 13.2, the temperature and pressure before compression are 300 K and 100 kPa respectively. Determine. to 3 significant figures, the net work produced by the engine in kJ/kg:
