The Types Of Cylinder Liner Sleeves

October 29, 2021

Latest company news about The Types Of Cylinder Liner Sleeves
Cylinder Liners are the interior metal components within the piston that protect it from the wear and tear of the opertaion of the motor.
There are three basic types of cylinder liner used: dry, wet and finned.
Dry Cylinder Liners
Dry cylinder liners are among the basic piston protectors. They must withstand extremely high temperatures and guard against impurities, so they are constructed of high-grade materials, such as cast iron and ceramic-nickle plating. Dry liners are much thinner than their counterpart, wet liners. They do not interact with the engine coolant but instead provide a very close fit with the jacket in the cylinder block to protect the piston from heat and impurities.
The typical thickness of a dry cylinder liners are from 2mm to 3mm. And a dry cylinder liner is much more widely used for petrol engines.

Wet Cylinder Liners

Wet cylinder liners protect the pistons in a different way than dry ones, but they are made from the same hardy material. They come in direct contact with the engine coolant. Sometimes the wet cylinder liners are fitted with tiny openings to help disperse the heat and impurities. These types of liners are called water-jacket liners but are simply another type of wet cylinder liner. If the liner doesn't have a cooling jacket, one is created by the liner by interacting with the jacket present in the cylinder block.

Finned Cylinder Liners

Finned cylinder liners are constructed of the same type of heat and impurity-resistant metal. This type of liner is designed for the air-cooled engine, and in operation works much like the dry cylinder liner in that the cooling medium for the motor is air. However, these liners are fitted with tiny fins which allow the inflowing air to draw with great force around the cylinder to provide cooling.
