The Cummins 4013171 Anti-Polishing Ring is a component designed to enhance the operation of heavy-duty trucks. Its purpose is to maintain the integrity of engine components by preventing the formation of corrosive acids that can arise from the combustion process. This part plays a role in ensuring the longevity and performance of the engine ¹.

Function and Operation

The Anti-Polishing Ring operates within the engine by controlling the flow of lubricating oil. It is positioned to direct oil towards the cylinder walls, ensuring that a consistent film of oil is maintained. This oil film is crucial for reducing friction and wear on the cylinder walls, as well as for cooling the piston and rings. By regulating oil flow, the ring helps to maintain the engine’s operational efficiency and protects critical components from excessive wear ².

Purpose of the Anti-Polishing Ring

The specific role of the 4013171 Anti-Polishing Ring in a truck’s operation is to contribute to engine performance and longevity. It does this by preventing the buildup of corrosive acids that can form on metal surfaces within the engine. These acids are a byproduct of the combustion process and can lead to corrosion if not managed properly. The ring’s design allows it to effectively shield engine components from these corrosive elements, thereby enhancing the engine’s durability and reliability ³.

Key Features

The Cummins 4013171 Anti-Polishing Ring is characterized by its material composition and design elements. Typically made from a durable metal alloy, the ring is engineered to withstand the high temperatures and pressures within the engine. Its design includes precise dimensions and a smooth surface finish, which are critical for its function in regulating oil flow and protecting engine components. These features contribute to the ring’s effectiveness in maintaining engine performance ⁴.

Anti-Polishing Ring (Part 4013171) in Engine Systems

The Anti-Polishing Ring (APR), identified by part number 4013171, is a component in various engine systems, including the QSV and D67 engines. Its primary function is to maintain the integrity and performance of the cylinder assembly by preventing the polishing of the cylinder liner.

Role in Engine Components

• Cylinder Block and Liner: The APR is strategically positioned within the cylinder block, specifically around the cylinder liner. It ensures that the liner’s surface remains rough enough to retain lubrication, which is vital for reducing friction and wear between the piston and the liner.

• Piston and Liner Interaction: As the piston moves within the cylinder, the APR helps to maintain an optimal surface texture on the liner. This is particularly important in high-performance engines where the piston’s travel is rapid and frequent.

• Prechamber Bits: In engines with prechamber combustion systems, the APR contributes to the overall efficiency by ensuring that the main combustion chamber’s components, including the prechamber bits, operate under reduced friction conditions.

• Engine Longevity: By preventing the polishing of the cylinder liner, the APR indirectly supports the longevity of the engine. It ensures that the piston rings maintain their sealing efficiency, which is crucial for combustion efficiency and overall engine performance.

• Liner Kit Integration: When installing a liner kit, the inclusion of the APR is standard practice. It complements the new liners by providing a consistent surface texture, which is essential for the proper functioning of the piston rings.

Conclusion

The Cummins 4013171 Anti-Polishing Ring is a vital component for maintaining the operational efficiency and durability of engine components. By ensuring the cylinder liner’s surface remains in optimal condition, this part contributes to the overall performance and longevity of the engine. Proper installation, maintenance, and understanding of its role in various engine systems are essential for maximizing its benefits.
