Air flows through an Otto cycle, beginning the compression process at a temperature of 45°C and a pressure of 95 kPa. The volume of gas present in the cylinder at the start of compression is 0.0025 m3. The compression ratio of the cycle is 9.3. The engine completes 1500 cycles per minute. Plot the power produced by the engine, the rate of heat addition for the engine, the thermal efficiency of the cycle, and the mean effective pressure for peak cycle temperatures varying between 2000 K and 3000 K, assuming that the air behaves as an ideal gas with variable specific heats.
