An Otto cycle begins its compression at 94kPa, 1230cm^3 and 11degC. The dispalacement volume and maximum temperature within the cycle is 1090cm^3 and 920degC and respectively.

Utilizing air standard assumptions, determine the:

a. heat addition and Wnet (kJ)

b. thermal efficiency (%)
c. mean effective pressure (kPa)

Consider the cycle as a model of the process in each cylinder of a spark-ignition engine. 

Show the T-s and P-v diagrams when solving. 

Note that specific heats are not constant
