A cylinder liner, also known as a cylinder sleeve, is a cylindrical component that is inserted into the cylinder block of an engine. Its purpose is to provide a smooth and durable surface for the piston to slide against. Cylinder liners are typically made of cast iron or steel and are designed to withstand the
All types of ship machines and parts get worn out due to continuous usage and working. Proper maintenance and routine checks are necessary to ensure that the machines work for a longer time. In this article, we will have a look at various reasons that lead to cylinder liner wear and how it can be minimised. Reasons for Cylinder Liner Wear The wear in the cylinder liner is mainly because of following reasons:
A truck engine works at the very limits of what metal can withstand, almost every single day: high temperatures, heavy loads, thousands of crankshaft revolutions per minute. Under these conditions, one of the most vulnerable components is the cylinder liner — a part whose condition directly determines compression, oil consumption, power output, and the engine's overall service life. One of the most insidious causes of premature liner failure is cavitation. Unlike ordinary mechanical friction, it destroys metal invisibly, from within the cooling system, and a driver often only learns about the problem once the engine has already lost compression or started "eating" coolant.

CYLINDER LINER forms the pressure boundary where the piston moves in a two-stroke marine diesel engine. Made from wear-resistant alloyed cast iron, it transfers heat to the cooling system through bore cooling passages to control temperature and prevent cracking and corrosion. Scavenge ports admit pressurized air to remove exhaust gases, while lubricator quills deliver cylinder oil to the piston rings, reducing wear, maintaining sealing, and protecting against corrosion.
