An ideal four-stroke gasoline 5.0 L engine running at 3000 rpm has an inlet state of 90 kPa, 280 K. After combustion, the gas temperature is 2000 K; the highest pressure reached in the cycle is 5 MPa. Using constant specific heats Cp=1.005 kJ/kg and Cv = 0.718 kJ/kg, determine (a) the compression ratio, (b) the cycle efficiency, (c) exhaust temperature, and (d) mean effective pressure (kPa). Draw (e) a P-v
diagram and (f) a T-s diagram
