Role of Part 4007899 Plain Hose in Engine Systems

The part 4007899 Plain Hose is an essential component in various engine systems, facilitating the smooth operation and maintenance of key engine functions.

Breather System

In the breather system, the 4007899 Plain Hose plays a significant role by allowing air to enter and exit the engine’s crankcase. This process is vital for maintaining the correct pressure within the crankcase, which in turn helps to prevent oil leaks and ensures that the engine operates efficiently. The hose connects to the breather valve, enabling the release of pressure build-up caused by the movement of the pistons and crankshaft. This pressure regulation is important for the longevity and performance of the engine ².

Crankcase Ventilation

Within the crankcase ventilation system, the 4007899 Plain Hose is responsible for channeling any gases that escape past the piston rings back into the intake system. This not only helps in reducing emissions but also ensures that the crankcase remains clean by preventing the accumulation of sludge and contaminants. The hose is typically connected to the Positive Crankcase Ventilation (PCV) valve, which meters the flow of these gases back into the intake manifold. This recirculation process enhances engine efficiency and reduces the environmental impact of the vehicle ³.

Conclusion

In summary, the Cummins 4007899 Plain Hose is a fundamental component in both the breather and crankcase ventilation systems, contributing to the overall performance, efficiency, and environmental compliance of the engine. Its precise engineering and compatibility with Cummins engines highlight the importance of using high-quality components in maintaining the reliability and performance of heavy-duty trucks ⁴.
