Втулка поршня двигателя Caterpillar 1227311

An Engine Piston Sleeve provides a wear-resistant cylinder surface for the piston’s reciprocating motion inside an engine. It ensures minimal friction between the piston and cylinder wall, maintaining effective sealing for combustion gases and preventing leakage. This part helps transfer heat from the piston to the cooling system, regulating temperature and avoiding damage due to excessive heat. Providing a replaceable running surface, it extends the engine’s operational life without replacing the entire engine block.Attributes:• Reduces energy losses caused by internal friction.• Supports optimal piston ring function for better sealing.• Supports consistent combustion chamber sealing for stable compression.Applications: An Engine Piston Sleeve is used within the engine’s cylinder assembly to provide a low-friction surface for piston movement while supporting heat transfer, sealing, and wear protection.
