Chongqing-Based Cummins Parts Supplier, 20+ Years of Heavy-Duty Power Solutions

Cummins K19 Cylinder Liner

The Cummins K19 Engine Cylinder Liner (Part No.: 4024767 / 3202240) is a core component specifically designed for the K19 series of industrial and engineering machinery engines. As the "cylinder wall" of the engine, it directly determines the compression ratio, combustion efficiency, and service life. The K19 cylinder liners provided by Wankang Electromechanical strictly adhere to Cummins engineering standards and are manufactured from high-wear-resistant alloy cast iron, ensuring excellent sealing performance and durability under heavy-duty conditions such as mining, marine, and power generation.

Core Features and Advantages

High Wear-Resistant Alloy Material

Made from special alloy cast iron and processed through precision honing, the inner bore surface forms an ideal oil-retaining cross-hatch pattern, effectively reducing piston ring friction and significantly enhancing wear resistance.

Superior Heat Dissipation

As a wet liner, its outer wall is in direct contact with the coolant. The optimized wall thickness design ensures excellent thermal conductivity, preventing liner deformation or cavitation due to high temperatures.

Precision Tolerance Fit

Strict dimensional control ensures a perfect fit between the liner, cylinder block, and piston assembly, effectively preventing "blow-by" and "gasket blowing," and maintaining engine power output.

Anti-Cavitation Design

Addressing the high-frequency vibration characteristics of the K19 engine, anti-corrosion elements are added to the liner material. When used with specialized DCA4 additives, it significantly delays cavitation damage to the liner's outer wall by the coolant.
