narrow soul
Tried the 4-stroke simulation to check it out, the flow of fuel and exhaust is poorly timed and would confuse someone entirely that doesn't already know how it works. Fuel appears to flow into the cylinder while the piston is compressing, and exhaust leaves when the fuel should be flowing in, while a vacuum is being formed. Doesn't instill confidence in the other simulations of things I don't fully grasp yet.

Please keep new stuff coming.. the prices are a little high though.

Don't bother unless you pay for the full version, there's only one simulation on the lite version. Just look it up on the internet.
