Question:

Heat is added to the air in an Otto cycle in the amount of 1200 kJ/kg. The compression ratio for this engine is 10. Air enters the cycle at 100 kPa and 20°C. Determine, using a cold air-standard analysis,
i) The temperature and pressure of the air at the end of the combustion process
ii) The cycle efficiency
iii) The net work output
iv) The mean effective pressure
