Cylinder liner, known as cylinder sleeves A cylindrical part called a cylinder liner is inserted into an engine block to create a cylinder. It is among the internal engine’s most crucial working parts. It is among the interior functioning parts of an engine that are most crucial. The beating heart of any engine is a constant battle against friction and wear. Imagine a tireless guardian standing between a rapidly moving piston and the engine block itself. Made from either cast iron alloys or lighter aluminium.
A special chromium coat is often added, creating a slick surface that reduces friction and keeps things running smoothly. Interestingly, the piston rings, the unsung heroes that keep the combustion chamber sealed, are often made from the same material as the liners themselves. It’s a match made in mechanical heaven, ensuring both components can withstand the intense heat and pressure within the engine. So next time you hear your engine purring, remember the silent hero within—the cylinder liner, standing guard against wear and tear, keeping your ride running like a champ.
WHAT ARE THE TWO MAIN TYPES OF CYLINDER LINERS
Dry Liners
Dry liners have a flange on top and are formed like a barrel. The flange secures the liner into the cylinder block. The liner fits inside the cylinder exactly. Excellent contact between the cylinder block and liner is necessary for the liner to cool efficiently. Additionally, during combustion, the combined thickness of the cylinder and liner resists impact loads, piston thrust, and gas pressure.
Dry liners are hence thinner and typically used to restore damaged liners. They have walls that are 1.5 mm to 3 mm thick. The cooling water and the dry liners do not come into direct contact with one another.
Wet Liners:
The fact that cooling water comes into contact with the liner gives rise to the moniker “wet liner.” This liner’s top features a flange that fits into the cylinder block’s groove. In order to stop cooling water leaks in the crankcase, sealing rings or packing rings are utilised to seal the bottom end of the wet liner. Because the wet liner must withstand thrust, impact, and gas pressure, its wall thickness is greater than that of the dry liner.
The wall thickness of the wet liner usually ranges from 3 to 6 mm to prevent corrosion, an aluminium coating is applied to the liner’s outside.

FAQ'S
1) What is a cylinder liner, and what is its purpose?
A cylinder liner, sometimes referred to as a cylinder sleeve, is a cylindrical part that forms the inner wall of a cylinder when it is installed in an engine block. Its main purpose is to act as a heat transmission medium between the engine block and the piston, giving the piston rings a strong, long-lasting surface.
