Four-stroke engine

A four-stroke engine is a type of internal combustion engine commonly found in cars and motorcycles. It completes a power cycle in four distinct steps: intake, compression, power, and exhaust. First, it draws in air and fuel during the intake stroke. Next, it compresses this mixture in the cylinder. The spark plug then ignites it during the power stroke, producing energy that moves the piston. Finally, the exhaust stroke expels the burnt gases. This cycle repeats, converting fuel into motion efficiently, making four-stroke engines popular for their balance of power, efficiency, and lower emissions.
