This article explains the main problems due to cylinder liner wear. So to know more, read this article till the end.
When assembled with an engine block to create a cylinder, a cylinder liner is formed from one or more cylindrical parts. It is one of the most essential functional components that make up the engine’s internal structure. As the inner wall of a cylinder, the cylinder liner acts as a sliding surface for the piston rings while also keeping the lubricant contained inside the cylinder walls. The outstanding feature of cylinder liners as a sliding surface, as well as these four essential characteristics, are the most significant functions of cylinder liners.
- Excellent anti-galling characteristics
- The cylinder liner itself will last longer as a result of less wear.
- Less wear on the piston ring of the companion piston.
- Less lubrication is used in the process.
The cylinder liner is responsible for preventing compressed gas and combustion gas from leaking outside the cylinder.
What are the characteristics of a high-quality cylinder liner?
- It should be strong and durable since it acts as the inner layer between the cylinder wall and piston arrangement. Because of this, the cylinder liner should be able to endure continuous piston motion and very high temperatures without affecting the engine’s performance.
- Excellent anti-galling characteristics – The liner should have excellent galling resistance and should not wear out with each combustion cycle.
- It acts as a sealant because high pressure and heat are generated during combustion, which is responsible for the power output. The cylinder liner’s primary function is to prevent compressed gas from escaping from the combustion chamber during combustion.
- Cylinder linings are classified into many categories based on the kind of engine, the type of combustion fuel, the application of the engine, the arrangement of the piston-piston rings, and the material composition.
Problems of Cylinder Liner Wear and Tear
The following factors are responsible for the majority of cylinder liner wear
- Frictional Wear
When two surfaces slide over one other, friction is created, which results in the wear and tear of both surfaces as they glide over each other. Liner wear occurs when piston rings slide across the cylinder liner, causing the wear to occur. Frictional wear is determined by a variety of variables, including the speed of movement between the surfaces, the material involved, the temperature, the load on the engine, the pressure, maintenance, lubrication, and the effectiveness of the combustion process.
This kind of cylinder liner wear is caused by the hard particles that are present and that are produced during the burning process. Abrasive wear is caused by the presence of catalytic fines in the fuel, the ash produced during combustion, metal swarf, dust, and accumulated wear particles in the lubricant.
A transitional step between engine testing and laboratory environment testing is achieved through the use of original engine parts in a closely controlled tribometer environment under realistic loading conditions, in conjunction with continuous and sensitive wear measurement methods and an in depth SEM analysis of the wear mechanisms.

How Can Cylinder Liner Wear Be Reduced to a Minimum?
The following procedures should be followed to reduce cylinder wear:
- By correctly treating the fuel oil, it is possible to prevent any water from entering the liner and causing damage.
- By ensuring that the cylinder oil is of the proper quality.
- By providing the proper feed rate in conjunction with a load change sensitive lubricating system
- By preventing moisture from the charge air from entering the system.
- By ensuring that the jacket water temperature is maintained.
- by providing high-quality, filtered fuel oil to the combustion chamber.
- By keeping the fuel injector and fuel system in good working order to ensure appropriate atomization and injection of fuel into the combustion chamber
- By doing frequent scavenging port inspections for the purpose of detecting piston ring wear and liner surface wear before they become severe.
