The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is at 100 kPa, 17 C, and 600 cm2. The temperature at the end of the isentropic expansion process is 800K. Using specific heat value at room temperature, determine:
1. The highest temperature and pressure in the cycle2. The amount of heat transferred, in kJ3. The thermal efficiency4. The mean effective pressure
