Abstract
The cylinder liner is an important part of a diesel engine which is a tube where the piston works and moves up and down to condense air and transfer heat energy into kinetic power. Factors such as cylinder liner wear, erosion / abrasion, corrosion, friction, cooling, lubrication system, and cracking of the cylinder liner can cause damage to the cylinder liner. the addition of leeway between the piston and cylinder can cause gas leakage, reduced compression pressure and reduced energy output. From the observations it can be seen that the most dominant cause is the lack of lubrication treatment. Then the cylinder liner can occur. Thus, lubricating checks and cylinder liner measurements must be carried out routinely to determine the condition of the lubricating oil quality and how far the cylinder liner is subjected to wear due to friction. The importance of maintenance of the cylinder liner on the main engine is needed, so the durabilityof these components becomes longer, maintained, and saves greater maintenance costs. To obtain as much engine power as possible, efforts are made to avoid leaks in the gases burned between the piston and cylinder, as well as sliding friction from the piston. The damage that occurs to the cylinder liner occurs due to the thermal load and vibration caused by the operating conditions of the diesel engine. Cylinder liner is a place for the piston to move from top dead center to bottom dead center which is shaped like a tube and the cylinder liner is also a place for the work process of a machine to take place where the suction, compression, effort and exhaust steps work in inside and the cylinder liner is also one part of the several components found in the engine block. Cylinder liner must be resistant to high temperatures, not easily worn and able to accept a large force from the piston. This Cylinder Liner must have the ability to absorb heat and transfer all the heat from the inner surface of the liner to the outer surface in direct contact with the cooling water. Keywords: cylinder liner, maintenance, ship engine.
