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 (layout, bore, stroke, cam, firing order) or describe what you want and have it generated on device. Watch it run in 3D, read live power and torque on the dyno, or push it past the limiter until it breaks. Post your engines to the global leaderboard and compare against other builders. Engine Simulator for iOS is an unofficial port. It is not affiliated with, endorsed by, or supported by AngeTheGreat (Ange Yaghi), the creator of the original open source Engine Simulator.
