Cylinder in Car Engine
What is a Cylinder?
A cylinder is a cylindrical shaped chamber in an engine in which a piston moves up and down. The piston is connected to the crankshaft by a connecting rod, and as the piston moves up and down, it turns the crankshaft.
How Do Cylinders Work?
As the piston moves up and down in the cylinder, it compresses the air-fuel mixture in the cylinder. When the piston reaches the top of the cylinder, the spark plug ignites the air-fuel mixture, causing it to explode. The explosion forces the piston back down the cylinder, which in turn turns the crankshaft.
Types of Cylinders
There are two main types of cylinders: inline cylinders and V-type cylinders.
- Inline cylinders are arranged in a straight line, one behind the other.
- V-type cylinders are arranged in a V-shape, with two banks of cylinders facing each other.
Number of Cylinders
The number of cylinders in an engine can vary from one to twelve. The most common number of cylinders is four, but six-cylinder and eight-cylinder engines are also common.
Size of Cylinders
The size of cylinders can vary from 0.5 liters to 5.0 liters. The size of the cylinders determines the displacement of the engine.
Displacement
The displacement of an engine is the total volume of all the cylinders in the engine. Displacement is measured in liters or cubic centimeters.
Compression Ratio
The compression ratio of an engine is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to the volume of the cylinder when the piston is at the top of its stroke. Compression ratios can range from 8:1 to 12:1.
Conclusion
Cylinders are an essential part of car engines. They are responsible for compressing the air-fuel mixture and turning the crankshaft.
