A four stroke engine has four cycles. Intake cycle, compression cycle, power cycle, and exhaust cycle. Each corresponds to one full stroke of the piston; therefore, the complete cycle requires two revolutions of the crankshaft to complete.
Here is a brief explanation on how it works.
- Intake cycle
The intake valve opens, the piston moves downward and fuel and air is sucked into the cylinder
- Compression cycle
The Intake valve closes and the piston moves upward, compressing the fuel and air mixture.
- Power cycle
A spark plug ignites the fuel/air mixture and the piston is forced downwards.
- Exhaust cycle
The piston moves upward and the exhaust valve opens, letting the fumes out of the cylinder.
