cylinder

A cylinder liner, also referred to as a sleeve or bushing, is a metal component installed on the inner wall of an engine cylinder. Its application in truck engines is primarily reflected in the following aspects: 1. Reduction of wear: The cylinder liner shields the cylinder wall from direct wear caused by the constant contact and friction between the piston and piston rings during operation. This significantly mitigates wear. 2. Enhanced sealing: The cylinder liner provides superior sealing performance, preventing high-pressure gases from the combustion chamber from leaking into the crankcase, thereby improving engine efficiency. 3. Simplified maintenance and replacement: In the event of damage or wear, the cylinder liner can be replaced without replacing the entire cylinder block, reducing maintenance costs and downtime. 4. Improved heat dissipation: Some cylinder liner designs incorporate materials with excellent thermal conductivity or feature special structural designs that enhance overall engine heat dissipation. 5. Extended engine life: By fulfilling the aforementioned functions, the cylinder liner contributes to extending the service life of the engine and maintaining its long-term stable and efficient operation.
