A 4-stroke engine is an internal combustion engine that completes a power cycle in four distinct strokes of the piston: intake, compression, power, and exhaust. During the intake stroke, air and fuel enter the combustion chamber; in the compression stroke, the mixture is compressed; in the power stroke, the mixture ignites, driving the piston down; and finally, in the exhaust stroke, the burnt gases are expelled. This design is known for its efficiency, lower emissions, and smoother operation compared to 2-stroke engines.
