Exhaust Valve Kit 4089672 Components and Their Roles

Valve Collet (3940123)

The Valve Collet is a component in the Exhaust Valve Kit 4089672. It serves as a retaining mechanism that secures the valve stem within the valve guide. This ensures that the valve remains properly aligned and centered during operation, which is for maintaining the seal between the valve and the valve seat. The collet’s precise fit and secure hold contribute to the overall efficiency and reliability of the valve train system.

Valve Stem Seal (3955393)

The Valve Stem Seal plays a role in the Exhaust Valve Kit by preventing the escape of combustion gases and oil vapors past the valve stem. This seal is positioned around the valve stem and creates a barrier that maintains the integrity of the combustion chamber. By effectively sealing the valve stem, it helps to reduce emissions and improve engine performance. The seal’s durability and resistance to high temperatures are for its long-term functionality within the kit.

Exhaust Valve (3968183)

The Exhaust Valve is the primary component of the Exhaust Valve Kit 4089672. It is responsible for controlling the flow of exhaust gases from the combustion chamber to the exhaust system. The valve opens and closes in synchronization with the engine’s operation, allowing for the efficient release of spent gases. The quality and design of the exhaust valve directly impact the engine’s performance, emissions, and overall durability. Its precise manufacturing and material properties are for withstanding the harsh conditions within the engine.

Conclusion

The Cummins Exhaust Valve Kit (Part #4089672) is a critical component for maintaining the efficiency and performance of commercial truck engines. Its role in facilitating the expulsion of exhaust gases contributes to better engine performance, fuel efficiency, and reduced emissions.
