Create a simple constant-volume model of the autoignition process and determine thetemperature and the fuel and product concentration histories. Also determine dP /dt as a function of time. Assume initial conditions corresponding to compression of a fuel–air mixturefrom 300 K and 1 atm to top-dead-center for a compression ratio of 10:1. The initial volumebefore compression is 3.68 ⋅ 10−4 m3, which corresponds to an engine with both a bore and astroke of 75 mm. Use ethane as fuel
