The Toyota Prius has an internal combustion engine that operates on the Atkinson cycle. The Atkinson cycle consists of the following thermodynamic processes:
Isentropic compression
Isochoric heat addition
Isentropic expansion
Isobaric heat rejection
A P-V plot of the Atkinson cycle is shown below:
Note that the expansion stroke (V4V3) is longer than the compression stroke. If the compression ratio is 9.2 and the expansion ratio is 13.5, the temperature and pressure before compression are 300 K and 100 kPa respectively. Determine, to 3 significant figures, the network produced by the engine in kJ/kg:
