How a Car Engine Works Step-by-Step
1. The Intake Stroke
The intake stroke is the first stroke of the four-stroke cycle. During this stroke, the intake valve opens and the piston moves down the cylinder. This creates a vacuum in the cylinder, which draws air and fuel into the cylinder from the intake manifold.
2. The Compression Stroke
The compression stroke is the second stroke of the four-stroke cycle. During this stroke, the intake valve closes and the piston moves up the cylinder. This compresses the air and fuel mixture in the cylinder, making it more combustible.
3. The Power Stroke
The power stroke is the third stroke of the four-stroke cycle. During this stroke, the spark plug ignites the air and fuel mixture in the cylinder. This causes the air and fuel mixture to burn, which creates pressure in the cylinder. The pressure forces the piston down the cylinder, which turns the crankshaft.
4. The Exhaust Stroke
The exhaust stroke is the fourth stroke of the four-stroke cycle. During this stroke, the exhaust valve opens and the piston moves up the cylinder. This forces the exhaust gases out of the cylinder and into the exhaust manifold.
5. The Repeat
The four-stroke cycle then repeats itself, with the intake stroke, compression stroke, power stroke, and exhaust stroke all occurring in sequence.
Additional Information
In addition to the four-stroke cycle, there are a number of other components that are involved in the operation of a car engine. These components include:
- The camshaft
- The crankshaft
- The valves
- The spark plugs
- The fuel injector
- The exhaust system
These components work together to ensure that the car engine operates smoothly and efficiently.
Conclusion
The car engine is a complex machine, but it is based on a simple principle: the four-stroke cycle. By understanding how the four-stroke cycle works, you can better understand how your car engine works.
