Cummins Overview

Cummins Inc. is a well-established manufacturer in the commercial truck industry, known for its range of engine and component products. The company has a history of innovation and quality, with a reputation for producing reliable and high-performance parts. The Cummins 4359971 Breather Tube is part of this tradition, offering a solution for maintaining engine health and performance in commercial trucks.

Role of Part 4359971 Breather Tube in Engine Systems

The 4359971 Breather Tube is an essential component in the arrangement of various engine systems, particularly in managing the crankcase breather system.

In the crankcase breather system, the Breather Tube facilitates the release of gases that accumulate within the crankcase. These gases, which include unburned fuel, combustion byproducts, and moisture, are a natural byproduct of the engine’s operation ². The Breather Tube allows these gases to escape, preventing pressure build-up that could lead to oil leaks, reduced engine efficiency, and potential damage to seals and gaskets.

The integration of the Breather Tube within the engine system ensures that the crankcase maintains a stable pressure environment. This stability is vital for the proper functioning of the piston rings and the overall lubrication system ³. By allowing controlled venting of gases, the Breather Tube helps in preserving the integrity of the engine’s internal components.

Additionally, the Breather Tube often connects to other components such as the air intake system or a PCV (Positive Crankcase Ventilation) valve. This connection enables the recirculation of crankcase gases back into the intake manifold, where they can be burned again in the combustion process. This not only reduces emissions but also enhances engine performance by ensuring that potentially combustible gases are utilized rather than released into the atmosphere.

Conclusion

In summary, the Cummins 4359971 Breather Tube plays a significant role in maintaining the efficiency and reliability of the engine by managing crankcase pressure and facilitating the recirculation of gases. Its robust design and high-quality materials ensure durability and effectiveness in demanding commercial truck operations.
