Question:

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 \(1 \mathrm{bar}\) 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. What has been the effect of dissociation? (See Chapter 10, P10.6.)

[0.79334, 119.1 bar, \(2883 \mathrm{~K} ; 0.8463,0.1071,0.0465]\)
