A gas injection system supplies a mixture of propane (left(mathrm{C}_{3} mathrm{H}_{8} ight)) and air to a spark-ignition

A gas injection system supplies a mixture of propane \(\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)\) and air to a spark-ignition engine, in the ratio of volumes of 1:30. The mixture is trapped at 1 bar and \(300 \mathrm{~K}\), the volumetric compression ratio is \(12: 1\), and the index of compression, \(\kappa=1.4\). Calculate the equivalence ratio, the maximum pressure and temperature achieved during the cycle, and also the composition (by volume) of the dry exhaust gas.
