An ideal Otto cycle with air as the working fluid has a compression ratio of 8. At the end of the heat rejection process, temperature decreases to ambient temperature (25 °C ), and at the end of the heat addition process temperature increases to 1107 °C. Use air standard assumption and calculate the following quantities. 1. The amount of heat transferred to the air during the heat addition process. 2. The thermal efficiency. 3. The thermal efficiency of a Carnot cycle operating between the same temperature limits.
