At the beginning of the compression process of an air-standard Otto cycle, P1 = 1.0 bar, T1 = 290 K, V1 = 400 cm3. The maximum temperature in the cycle is 2200 K and the compression ratio is 8. Determine: a) the heat addition in kJ, b) the net work in kJ, c) the thermal efficiency, and d) the mean effective pressure, in bar.
