Air enters an air - standard Otto cycle with a pressure and temperature of 1 bar and 15 C respectively. The compression ratio is 9 and the bore and stroke of the cylinder are (10 cm, 12 cm). The heat added to the air due to combustion is 500 J. Determine:
a) the volume, temperature and pressure at all state points,
b) the thermal efficiency, and c) the mean effective pressure, in atm.
Take y=1.4; R =0.287 kJ/kg.K
