1. A spark ignition engine is proposed to have a compression ratio of 10 while operating with a low temperature of 200-degree C and a low pressure of 200 kPa. If the work output is to be 1000 kJ/kg, calculate the maximum possible thermal efficiency and compare with that of a Carnot cycle. Also calculate the MEP.
