Wear resistant protective sleeve for combustion chamber -1979322 Caterpillar cylinder liner
In the combustion chamber structure of an engine, the cylinder liner is the "core wear-resistant component" that directly cooperates with the piston and withstands high temperature and high pressure. Its wear resistance and sealing directly determine the cylinder life, combustion efficiency, and engine power output stability. The 1979322 Caterpillar cylinder liner, with "original factory level matching accuracy" and "extreme working condition tolerance characteristics" as its core, has become a reliable guarantee for Caterpillar equipment. Its value lies not only in "forming the combustion chamber", but also in its dual role of "protecting the cylinder body and being strong and durable".
As an original Caterpillar accessory, its inner diameter accuracy and wall thickness uniformity are perfectly matched with the cylinder body and piston (specific compatible models can be consulted with customer service). The inner surface, which has undergone factory honing treatment (roughness ≤ 0.8 μ m), fits tightly with the piston ring (precise clearance control), ensuring combustion chamber sealing (preventing gas leakage) and reducing friction loss (30% lower than ordinary cylinder liners). This adaptability avoids "poor sealing" (cylinder pressure drop) or "excessive wear" (such as full load operation of loaders) caused by size deviation of universal cylinder liners, and reduces the risk of cylinder body scrap from the source.
Material focus on high temperature and high pressure resistance: Made of alloy cast iron (containing chromium and molybdenum elements), nitrided treatment (surface hardness up to HV450), excellent creep resistance (able to withstand long-term high temperature deformation ≤ 0.02mm), and can resist combustion high temperature and gas corrosion above 400 ℃ in the cylinder. The outer wall of the cylinder liner is equipped with a heat dissipation groove to accelerate heat conduction (avoid local overheating) and adapt to extreme working conditions of continuous heavy load of the equipment.
The implicit value is reflected throughout the entire cycle: the wear-resistant characteristics extend the life of the piston ring by 40%; Good sealing ensures sufficient combustion (reducing fuel consumption by 3% -5%); Protect the cylinder block from direct wear and extend the engine overhaul cycle by 50%. If the cylinder liner fails, it can result in a decrease in power and oil entering the combustion chamber, or in severe cases, the cylinder block may be scratched by the piston, leading to a significant increase in maintenance costs.
