Quite possibly the dumbest project I've ever undertaken, this was an odyssey but well worth it in the end. It's hard to fully explain the depth of the rabbit hole that I was led down and I ended up having to study things like fluid dynamics, physics and chemistry. As the title suggests, this is a physically realistic (or at least, somewhat realistic) internal combustion engine simulation. It also generates audio which I feel is some of the best procedurally generated audio for a V8 engine I've ever heard.
