The intake and exhaust valves close, sealing the combustion chamber. A piston lies at the bottom and begins to rise, compressing the air-fuel mixture. When the piston reaches the topmost point of its path, a spark plug ignites the mixture and causes a miniature explosion. Vapors expand inside the chamber and push the piston downward. This rotates the crankshaft and powers your vehicle.
Note that the approach described above needs the spark plug to ignite the compressed air-fuel blend. If this spark is unavailable, or too weak, the mixture cannot be ignited. This causes a misfire.
