Sleeve 224718

Sleeve 224718

The Sleeve (Part No. 224718) is a critical cylinder liner designed for specific gas engine models. It plays a fundamental role in engine performance, durability, and efficiency.

Function & Role:

Its primary function is to form the inner wall of the engine cylinder. It provides a precise, durable, and heat-conductive surface for the piston to move within. Key roles include:

Containing the combustion pressure.

Guiding the piston rings to ensure effective sealing (compression, combustion gases, oil control).

Transferring combustion heat from the piston and rings to the engine's coolant circuit via the surrounding jacket.

Usage & Key Features:

This component is installed during an engine overhaul or cylinder reconditioning. Proper installation is crucial and requires specific tools and procedures, including precise measurement of bore diameter and surface finish (honing).

Its key functional features typically include:

High-Grade Material: Made from wear-resistant cast iron to withstand high temperatures and pressures.

Advanced Surface Technology: The inner bore features a honed pattern or special coating (e.g., plateau honing) to optimize oil retention, reduce friction, and minimize blow-by.

Precision Cooling: Designed with optimal wall thickness and geometry to ensure efficient heat transfer, preventing overheating and maintaining stable operating temperatures.

In summary, the Sleeve 224718 is an essential wear part that ensures the longevity, sealing integrity, and thermal management of the cylinder, directly impacting the engine's power output, efficiency, and operational reliability.
