Cylinder Sleeve

A cylinder sleeve, also known as a cylinder liner, is a cylindrical component that is inserted into the cylinder block of an engine. It provides a smooth and durable surface for the piston to move up and down within the cylinder.

Cylinder sleeves are typically made of cast iron or steel and are designed to withstand the high temperatures and pressures generated by the combustion process in an engine. They are commonly used in engines that require a high level of performance and durability, such as those found in cars, trucks, motorcycles, and heavy machinery.

The main purpose of a cylinder sleeve is to protect the cylinder block from wear and damage caused by the piston rings and the combustion process. It also helps to maintain the proper clearance between the piston and the cylinder wall, ensuring efficient combustion and reducing the risk of oil leakage.

In addition to protecting the cylinder block, cylinder sleeves can also be used to increase the displacement of an engine. By increasing the bore size of the cylinder, the engine's displacement can be increased, resulting in more power and torque.

Overall, cylinder sleeves play a crucial role in the performance and longevity of an engine by providing a durable and smooth surface for the piston to operate within the cylinder.
