PRODUCT GUIDE

Cylinder Liner Kit 3800328

The cylinder liner is a cylindrical part that is placed in the cylinder block hole of the body and is held tightly by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water.

This is a cylinder liner (model 6CT8.3 QSL8.9/OEM NO 380-0328) for diesel engines, a core component of the engine block and a key single item in cylinder liner kits. It forms the combustion chamber together with the piston and cylinder head, provides precise guiding space for the piston's reciprocating motion, and withstands high temperature, high pressure and mechanical friction generated by combustion. It is suitable for the power system of diesel engines and is a common accessory for engine overhaul or component replacement.

Core Advantages

• Precise Adaptation:The size fully matches the corresponding diesel engine block, and the installation tolerance is controlled within ±0.01mm, which can be directly assembled without additional processing.
• Wear Resistance:The inner wall adopts strengthening treatment process, with surface hardness up to HV800+, which effectively reduces the friction loss between piston rings and cylinder walls and extends service life.
• Efficient Heat Dissipation:Made of high thermal conductivity alloy material, it can quickly dissipate combustion chamber heat and avoid component deformation caused by local overheating.
• Reliable Sealing:The outer wall is precision-machined. After interference fit with the cylinder block, it can tightly isolate the coolant from the combustion chamber and prevent leakage risks.

Performance Parameters

• Dimension Specification:It is suitable for the cylinder block size of the corresponding diesel engine, and the inner diameter, outer diameter and height all meet the original factory assembly standards.
• Operating Temperature:It can withstand long-term cylinder high temperature of 180℃, and the short-term peak temperature can reach 250℃.
• Service Life:Under normal working conditions, the service life is not less than 12000 hours, which matches the engine overhaul cycle.
• Compressive Strength:It can withstand a cylinder burst pressure of ≥20MPa, ensuring structural stability under extreme working conditions.
