A gasoline engine is modeled as an Otto cycle. It has at temperature and pressure at the beginning of  compression of 10°C and 90 kPa. The compression ratio is 7 and the specific energy added to the air during the heat addition process is 1432.46 kJ/kg.
Determine: USING CONSTANT SPECIFIC HEAT METHOD
1. The maximum temperature in the cycle
2. The maximum pressure in the cycle
3. The thermal efficiency of the cycle
4. The mean effective pressure
