Air flows through an Otto cycle, beginning the compression process at a temperature of 50°C. The volume of gas present in the cylinder at the start of compression is 0.001 m3. During the heat addition process, 1200 kJ/kg of heat is added to the air. The compression ratio of the cycle is 8.5. Plot the work produced during one cycle, the maximum pressure in the cycle, the thermal efficiency of the cycle, and the mean effective pressure for pressures at the beginning of compression ranging between 50 kPa and 150 kPa, assuming that the air behaves as an ideal gas with constant specific heats.
