How a Car Engine Works Step-by-Step

1. Intake Stroke

The intake stroke begins with the piston at the top of the cylinder. The intake valve opens, allowing air and fuel to enter the cylinder. The piston then moves down the cylinder, drawing the air and fuel mixture in.

2. Compression Stroke

The compression stroke begins with the intake valve closing. The piston then moves up the cylinder, compressing the air and fuel mixture. This compression heats the mixture and makes it more combustible.

3. Power Stroke

The power stroke begins with the spark plug igniting the air and fuel mixture. This creates a controlled explosion that forces the piston down the cylinder. The downward motion of the piston turns the crankshaft, which is connected to the wheels.

4. Exhaust Stroke

The exhaust stroke begins with the exhaust valve opening. The piston then moves up the cylinder, pushing the exhaust gases out of the cylinder. The exhaust gases are then expelled through the exhaust system.

5. Repeat

The four strokes of the engine cycle are repeated over and over again to keep the engine running. The engine’s speed is controlled by the amount of fuel that is injected into the cylinders. More fuel results in a faster engine speed.

Additional Details

* The four strokes of the engine cycle are also known as the Otto cycle.
* The Otto cycle is a type of internal combustion engine cycle.
* Other types of internal combustion engine cycles include the diesel cycle and the Atkinson cycle.
* The size of an engine is measured in liters.
* The number of cylinders in an engine can vary from 2 to 12.
* The most common engine configuration is a V6 engine.

Conclusion

Car engines are complex machines, but the basic principles of operation are relatively simple. By understanding how a car engine works, you can better appreciate the engineering marvel that powers your vehicle.
