The initial conditions for an air-standard Otto cycle operating with a compression ratio of 8:1 are 95 kPa and 17o C. At the beginning of the compression stroke, the cylinder volume is 2.20 L ( 1 L=0.001 m3)and 3.60 kJ of heat is added during the constant volume heating process. Calculate the pressure and temperature at end of each process of the cycle, and determine the thermal efficiency and mean effective pressure of the cycle.
