Engine Simulator (Beta)
The complete Engine Simulator in your browser: start an engine, drive it through the gears, put it on the dyno, slow it down to watch the valves and the flame, and hear it. Every cylinder's gas pressure, valve flow and combustion is simulated thousands of times a second and the exhaust pulses become the sound. It is a sound and feel simulation, not a measuring tool: for torque and power predictions from your engine's specs use the Dyno Simulator.

Engine script
Edit the current engine (Edit script) and press Reload edited or Ctrl+Enter, as you would edit main.mr and press Enter in the desktop app. Or paste a single-file engine script written for Engine Simulator (for example a main.mr from the community parts catalog) and load it as a new engine. If a script doesn't compile, the engine that was running keeps running.
