Engine Simulator 3D

Start the engine and move the throttle to hear and see the revs change. Explore six engines in 3D: inline-4, inline-5, inline-6, V8, V10 and V12.

• Six engines
Explore Inline-4 High-rev, Inline-5 Turbo, Inline-6 Twin, V8 Low-rev, V10 High-rev and V12 Grand. Drag to rotate the engine, then open the expanded view to inspect moving pistons, connecting rods and the crankshaft.

• Four gearboxes
Choose a 5-speed manual, 6-speed manual, 8-speed automatic or 7-speed dual-clutch. Use the gear controls and clutch, brake and throttle pedals for the selected gearbox. Follow the engine state on the tachometer and gear display.

• Exhaust and sound settings
Change the exhaust and tuning in Settings and compare the sound from idle to high revs. Audio is generated in real time from the engine's behavior; it does not play recordings of real vehicles.

• Ads and access
The default inline-six engine is available without watching an ad. A confirmed rewarded ad applies the selected engine and lets you select that engine again without another rewarded ad for 24 hours. Passes are stored separately for each engine on this device. Reopening the app restores the last confirmed engine; an expiring pass does not force a change away from the current engine. If an ad is unavailable or a reward is not confirmed, you can keep using the current engine. Banner ads may appear at the bottom of the screen.

No account or sign-in is required. The app interface is available in 15 languages, including English, Korean, Japanese and Chinese. The engines are original designs and do not reproduce any specific manufacturer or vehicle.
