The four strokes are... Intake, Compression, Combustion, Exhaust.
The heat from the combustion reaction causes the pistons to move during the power stroke in the four-stroke engine cycle. This is when the high-pressure gases from the combustion expand, pushing the piston downward.

Number 1, the intake stroke. Weather it is fuel injected or has a carburetor makes no difference. Most internal combustion engines today are 4 stroke engines. The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of Otto Cycle and Diesel engines. The four steps in this cycle are often informally referred to as "suck, squeeze (or squash), bang, blow." Intake stroke

The piston stroke that prepares the fuel mixture for combustion in a four-stroke cycle is the compression stroke. During this stroke, the piston moves upward in the cylinder, compressing the air-fuel mixture that was drawn in during the intake stroke. This compression increases the temperature and pressure of the mixture, making it more conducive to ignition when the spark plug fires.
A 4 stroke engine is also referred to as a four cycle refers to the internal combustion whereby the piston completes 4 separate strokes with a single thermodynamic cycle.
