cylinders. Most cars, trucks, and motorcycles have internal combustion engines. 2. An internal combustion engine works in four steps, called strokes. These strokes are intake, compression, power, and exhaust. 3. The cycle begins with the intake stroke. During this stroke, fuel and air enter the combustion chamber. 4. Next is the compression stroke. The piston moves up, compressing the fuel and air mixture. 5. The power stroke follows, where the spark plug ignites the compressed fuel and air. This explosion forces the piston down, generating power. 6. Finally, the exhaust stroke pushes the burned gases out of the combustion chamber. 7. This cycle repeats over and over again, creating the energy that moves the vehicle.
