An engine operates on the air standard Otto cycle The condit

An engine operates on the air standard Otto cycle. The conditions at the start of compression are 27 degree C and 100 kPa. The heat added is 1840 kJ/kg. The compression ratio is 8. Determine the temperature and pressure at each point in the cycle, the thermal efficiency, and the mean effective pressure.

Solution

The answer of following question is as follows.

The thermal efficiency of the given cycle is 78%

The mean effective pressure is 78
