A gasoline engine operates on the ideal Otto cycle. At the start of the cycle, natural dry air is at 298 K and 100kPa at the beginning of an isentropic compression. The air volume is decreased by 9 times when the piston reaches the top dead center. The compressed air gains heat of 325 kJ/kg in the constant-pressure heat addition. Accounting constant specific heats at room temperature, determine (a) the maximum temperature and the maximum pressure of the air in the cycle, (b) the net specific work output, and (c) the mean effective pressure of the cycle.
