How a Car Engine Works

Components of a Car Engine
- Cylinder: The cylinder is where the combustion of fuel and air takes place.
- Piston: The piston moves up and down inside the cylinder, compressing the air and fuel mixture and then pushing the exhaust gasses out.
- Connecting rod: The connecting rod connects the piston to the crankshaft.
- Crankshaft: The crankshaft converts the up-and-down motion of the pistons into rotary motion.
- Camshaft: The camshaft controls the opening and closing of the valves.
- Valves: The valves control the flow of air and fuel into the cylinder and the exhaust gasses out of the cylinder.
- Spark plug: The spark plug provides the spark that ignites the air and fuel mixture.
- Fuel injector: The fuel injector sprays fuel into the cylinder.
- Air filter: The air filter removes impurities from the air before it enters the engine.
- Exhaust system: The exhaust system removes the exhaust gasses from the engine.
How a Car Engine Works
- Intake stroke: The intake valve opens, and the piston moves down, drawing air and fuel into the cylinder.
- Compression stroke: The intake valve closes, and the piston moves up, compressing the air and fuel mixture.
- Power stroke: The spark plug ignites the air and fuel mixture, and the expanding gasses push the piston down.
- Exhaust stroke: The exhaust valve opens, and the piston moves up, pushing the exhaust gasses out of the cylinder.
The four strokes of the engine are repeated continuously, providing power to the car.
