Car Engine Simulator 3D

From an inline-four to a V12, watch pistons and valves move in 3D and hear every rev. Press the throttle, watch the needle climb, feel the gears change.

What actually happens inside an engine?

Engine Simulator shows the pistons, connecting rods, crankshaft and valves of a real engine moving in 3D. Press the throttle and the revs climb, the sound changes and the gearbox shifts.

■ Five engines • Inline-4 2.0 L — the everyday car engine • Inline-6 3.0 L — silky smooth, hardly any vibration • V8 5.0 L — lots of torque and a deep voice • V10 5.2 L — sharp all the way to high revs • V12 6.5 L — the strongest and smoothest

■ Three gearboxes • 6-speed manual — shift yourself; let the revs fall too low and it stalls • 7-speed dual-clutch — quick automatic shifts and launch control • 8-speed automatic — smooth pull-away through a torque converter

■ See inside • Clear view: moving parts through the block • Exploded view: head and block pulled apart • Cylinder inspector: intake, compression, power and exhaust strokes, cylinder by cylinder • 3D speed 1/2 to 1/8: slow down a crank spinning at thousands of rpm • Rotate and zoom with your fingers

■ Feels real • Engine sound built from each engine's firing order • Haptics on start-up, limiter cuts and shifts • Accelerator that responds like a real pedal (change it in Settings) • Engine braking, creep and kickdown

■ Also • Portrait and landscape • 22 languages (change in Settings) • No data collection, works offline

For car lovers, students learning how engines work, and anyone who just likes the sound of one.
