The four-stroke Otto engine is the most commonly used engine in cars. This type of engine works by converting fuel into energy through a series of four strokes: intake, compression, combustion, and exhaust. During the intake stroke, the fuel and air mixture is drawn into the engine. In the compression stroke, the mixture is compressed to increase its energy potential. The combustion stroke ignites the mixture, causing it to expand and push the piston down. Finally, the exhaust stroke releases the waste gases from the engine.
