Engine Simulator is a physics-based piston engine sandbox. The sound and motion come from a real rigid body simulation of the crank, pistons, valves, and combustion, not recordings.
Start an engine, work the throttle, and tune its fuel and ignition maps in the ECU. Build one from scratch or describe what you want and have it generated by AI.
Engine Simulator for iOS is an unofficial port. It is not affiliated with AngeTheGreat, the creator of the original open source Engine Simulator.
