Cummins®

The Cummins 4376233 Piston Ring Kit is a specialized component designed for use in heavy-duty truck engines. Its purpose is to enhance the performance and efficiency of the engine by ensuring proper sealing of the combustion chamber, controlling oil consumption, and contributing to overall engine longevity. This part is significant in the operation of heavy-duty trucks, as it plays a role in maintaining engine efficiency and reliability under demanding conditions.

Basic Concepts of Piston Ring Kits

Piston ring kits are components within an engine, consisting of multiple rings that fit into grooves on the piston. These rings serve several functions: they seal the combustion chamber to prevent gas leakage, control the amount of oil that reaches the combustion chamber, and scrape excess oil from the cylinder walls to reduce oil consumption and maintain engine efficiency. The proper functioning of piston rings is important for the engine’s performance, fuel efficiency, and durability ¹.

Components of Cummins Piston Ring Kit 4376233

The Cummins Piston Ring Kit 4376233 comprises essential components that work synergistically to ensure optimal engine performance. Each component within this kit plays a distinct role in maintaining the integrity and efficiency of the piston assembly.

Oil Piston Ring (4349930)

The oil piston ring, identified by the part number 4349930, is a critical component within the kit. Its primary function is to control the lubrication of the cylinder wall. By regulating the thickness of the oil film, the oil piston ring helps to minimize friction between the piston and the cylinder, thereby reducing wear and enhancing the longevity of the engine components.

Compression Piston Ring 1 (4349931)

The first compression piston ring, designated as 4349931, is responsible for sealing the combustion chamber. This ring is positioned closest to the top of the piston and plays a vital role in maintaining compression within the cylinder. Effective sealing by this ring ensures that the air-fuel mixture is compressed efficiently, leading to better combustion and increased engine power.

Compression Piston Ring 2 (4349932)

The second compression piston ring, with the part number 4349932, works in conjunction with the first compression ring to provide a secondary seal. This additional sealing helps to further contain the combustion pressure, enhancing the overall efficiency of the engine. The presence of two compression rings allows for a more robust sealing mechanism, which is crucial for high-performance engines.

Each of these components is meticulously engineered to meet Cummins’ stringent quality standards, ensuring that the Piston Ring Kit 4376233 delivers reliable performance and durability. The combination of these rings within the kit is designed to optimize engine efficiency, reduce emissions, and prolong the service life of the engine.
