A spark-ignition engine has a compression ratio of 8, an isentropic compression efficiency of 85%, and an isentropic expansion efficiency of 95%. At the beginning of the compression the air in the cylinder is at 13 psia and 60 °F. The maximum gas temperature is found to be 2300 °F by measurement. Determine the heat supplied per unit mass, the thermal efficiency, and the MEP using cold air standard analysis
