The engine is the car’s core, and cylinders convert fuel into motion. Knowing their role helps drivers and enthusiasts make smart choices in buying, maintaining, and understanding vehicle performance.

 

What Is a Cylinder?

A cylinder is a precisely engineered, cylindrical chamber typically made from cast iron or aluminum alloys to withstand high temperatures and pressures. Inside it, the piston moves in a reciprocating motion—up and down. Engines vary in the number of cylinders, usually ranging from 3 to 12, and this number directly affects the engine’s performance, smoothness, and efficiency.

 

Cylinder Function and the Combustion Cycle

The core energy-generating process occurs within each cylinder through a four-stroke combustion cycle:

- Intake Stroke: The intake valve opens, and the piston moves downward, creating a vacuum that draws in the air-fuel mixture.

- Compression Stroke: Both intake and exhaust valves close, and the piston moves upward, compressing the mixture to increase its energy density and flammability.

- Power Stroke: The spark plug ignites the compressed mixture, causing an explosion that forces the piston downward with great force—this motion is ultimately converted into rotational energy that drives the wheels.

- Exhaust Stroke: The exhaust valve opens, and the piston moves upward again, expelling combustion gases from the cylinder to prepare for the next cycle.
