Cylinder conditions at the start of compression in an SI engine operating at WOT on an air-standard Otto cycle are 60°C and 98 kPa. The engine has a compression ratio of 9.5:1 and uses gasoline with Combustion efficiency is 96%, and it can be assumed that there is no exhaust residual.

Calculate:

(a) Temperature at all states in the cycle. [°C]

(b) Pressure at all states in the cycle. [kPa]

(c) Specific work done during power stroke. [kJ/kg]

(d) Heat added during combustion. [kJ/kg]

(e) Net specific work done. [kJ/kg]

(f) Indicated thermal efficiency. [%]
