A four-cylinder spark ignition engine has a compression ratio of 8, and each cylinder has a maximum volume of 0.6L. At the beginning of the compression process, air is at 98kPa and 17°C and the maximum temperature of the cycle is 1800°C. The pressure is doubled during the heat addition process. Account for variation of specific heats with temperature and model the engine as a dual cycle.

Determine:
a) The amount of heat supplied per cylinder (kJ)
b) The thermal efficiency of the cycle
c) The number of revolutions per minute for a net power output of 60kW
d) The mean effective pressure for the cycle.
