\-| The compression ratio in an air-standard Otto cycle is 8. At the beginning of the compression stroke the pressure is 0.1 MPa and the temperature is 15°C. The heat transfer to the air per cycle is 1800 kJ/kg air. Determine: 1. The pressure and I temperature at the end of each process of the cycle. 2. The thermal efficiency.
