The Four Stroke Engine

The four stroke engine is the most common engine type in motor vehicles.
It powers almost all cars and trucks on the road today, including yours.

1. Intake Stroke

The piston drops in the cylinder, sucking air into the chamber at the same moment that fuel is injected. Two of the three ingredients for combustion are ready to fire.

2. Compression Stroke

With both intake and exhaust valves closed, the piston returns to the top of the cylinder compressing the air or fuel-air mixture into the cylinder head.

3. Power Stroke

With the mixture compressed the spark plug fires, and the resulting explosion propels the piston downward again, starting its second revolution.

4. Exhaust Stroke

The piston once again returns to the top while the exhaust valve is open. This action expels the spent fuel-air mixture through the exhaust valve(s).
