An engine with a 15:1 compression ratio operates on the mixed air standard cycle. At the beginning of compression, the pressure is 0.97 bar and the temperature is 21C. After compression, heat supply at constant volume raises the air temperature to 1090C and the heat supply at constant pressure takes place over 4% of the stroke. Calculate the cycle efficiency and its maximum pressure and temperature.
