in an air standard otto cycle , the air at the beginning of the compression stroke is at 95 kpa and 22c ,and the cylinder volume is 0.0028 m^3 . the compression ratio is 9 and 4.3 kj are added during the heat addition process .you may assume ideal gas with constant specific heat cv=0.85kj/kg-k and k=1.4
a- calculate the maximum temperature and maximum pressure
b- determine the cycle thermal efficiency
c- determine the mean effective pressure
