All pistons connect to spinning crankshaft so they go up and down regularly.

Piston in cylinder goes down (injection stroke).

Inject fuel and air in cylinder.

Piston goes up (compression stroke).

Gas is compressed.

Spark plug goes off igniting fuel/air mixture.

Combusting fuel rapidly expands pushing piston down (power stroke).

The piston comes back up expelling exhaust (exhaust stroke).

Rinse and repeat.

Gas is squirted into a chamber along with air and lighted up with an electric spark which causes a small explosion which pushes a piece of metal (piston) through a tube (cylinder) which pushes onto a shaft (crankshaft) rotating it along with other similar tubes. The alternating explosions and movements of the different pistons creates a cycle where the crankshaft spins, the explosions occur, the exhaust is expelled, the valves push in more gas and more air and the cycle repeats itself over and over again. The movement from the crankshaft is eventually translated mechanically into movement to the wheels.

Here is a video about the engine.

the working parts move up inside the pots and SUCK in air/fuel mix

The working parts move down and SQUEEZE the mix in the pots (makes it more explosive)

Spark ignites squeezed mix and BANG

The stink left over from the bang gets BLOWn out

Air and fuel is burned in a cylinder. Expanding gases from the fuel burning pushes the piston down the cylinder in a reciprocating motion. Rod connecting the piston to the crank shaft turns reciprocating motion into rotating motion.

Car engines work on a 4-stroke cycle:

Intake:
Intake valve opens, fuel and air is drawn into the cylinder by the motion of the piston moving down in the cylinder.

Compression:
Intake valve closes, piston pushes up the cylinder and compresses the fuel and air mixture

Power:
Spark from spark plug ignites the fuel and air mixture, expanding gasses force the piston back down the cylinder.

Exhaust: Exhaust valve opens, piston moves up the cylinder and pushes exhaust gasses out of the cylinder. Cycle repeats a couple thousand times per minute
