spark ignition engine that operates on Otto cycle has a compression ratio of 10. At the beginning  of the compression process, air is at 100 kPa and 25 C. 750 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Consider the variation of specific heats with  temperature. 1)Describe with the aid of diagrams the operational sequence of four stroke spark ignition  engines 2)Explain the mechanical efficiency for ideal otto cycle of two and four stroke engines
