11Z Engine Cylinder Liner 11461-78300 11461-78301 For Toyota

Product Features

The cylinder liner is a key component in the engine, located inside the cylinder block, providing the cylinder wall surface and forming an airtight working space. Here are some basic information about cylinder liners:

Material: Common cylinder liner materials include cast iron, aluminum alloy, and steel. Cast iron is the most commonly used cylinder liner material due to its excellent wear resistance and thermal conductivity. Aluminum alloy cylinder liners are commonly used in high-performance engines because they have higher thermal conductivity and lower weight. Steel cylinder liners are typically used for certain special applications, such as high-pressure turbocharged engines.

Sealing performance: The cylinder liner needs to form a seal with the piston to ensure that the pressure of the cylinder does not leak. Good sealing performance is crucial for the performance and combustion efficiency of the engine.

Thermal expansion characteristics: The cylinder liner needs to have appropriate thermal expansion characteristics in order to fit well with the piston when the engine is running. They should be able to expand at high temperatures and maintain appropriate clearance with the piston to ensure smooth movement of the piston.

Lubrication performance: The cylinder liner needs to provide appropriate lubrication between the piston to reduce friction and wear. Some cylinder liners are coated with special lubricating materials on their internal surfaces to provide better lubrication performance.

Size and geometry: The size and geometry of the cylinder liner may vary according to the requirements of the engine design. They need to accurately adapt to the cylinder diameter and stroke of the engine to ensure correct sealing and piston movement.
