3-1. 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 AF = 15.5. Combustion efficiency is 96%, and it can be assumed that there is no exhaust residual.

Calculate: (a) Temperature at all states in the cycle. [0C]

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

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

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

(£) Indicated thermal efficiency. [%]
