Compatibility with Cummins Engines

The Air Crossover Tube, part number 3040262, is designed to fit seamlessly with various Cummins engine models. This component is integral to the air intake system, ensuring efficient airflow management across the engine.

For the N14 CELECT and N14 MECHANICAL engines, the Air Crossover Tube is a critical part of the air management system. It connects the turbocharger to the intake manifold, facilitating the distribution of compressed air to the engine cylinders. This ensures optimal performance and efficiency, particularly in high-demand scenarios.

In the case of the NH/NT 855 engines, the Air Crossover Tube serves a similar purpose. It is engineered to maintain consistent air pressure and flow, which is essential for the engine’s overall performance. The design of this part ensures that it integrates smoothly with the existing air intake components, providing a reliable and durable solution for maintaining engine efficiency.

The Air Crossover Tube’s compatibility with these engines underscores Cummins’ commitment to providing high-quality, reliable parts that enhance engine performance and longevity.

Role of Part 3040262 in Engine Systems

The Air Crossover Tube, identified by part number 3040262, is an essential component in the orchestration of airflow within engine systems, particularly those equipped with turbochargers. Its primary function is to facilitate the smooth transition of pressurized air from one turbocharger to another, ensuring balanced air distribution across the engine’s cylinders. This balanced airflow is vital for maintaining uniform combustion, which directly impacts engine performance, efficiency, and longevity.

In turbocharged engine systems, the Air Crossover Tube connects the turbochargers, allowing the air compressed by one turbocharger to be shared with the other. This setup is particularly beneficial in twin-turbo configurations, where two turbochargers work in tandem to enhance engine performance. The tube ensures that the air, once compressed, is evenly distributed, preventing any single turbocharger from overworking and potentially leading to uneven engine performance or damage.

Moreover, the Air Crossover Tube plays a significant role in the turbocharger mounting system. It not only aids in the physical connection between turbochargers but also contributes to the structural integrity of the turbocharger assembly. By providing a stable and secure pathway for air, it helps in maintaining the optimal positioning and operation of the turbochargers. This is particularly important in high-performance engines where precision and reliability are paramount.

Conclusion

In summary, the Air Crossover Tube (part 3040262) is a key component in turbocharged engine systems, facilitating efficient air distribution and contributing to the overall performance and reliability of the engine. Its integration with the turbocharger and turbocharger mounting system underscores its importance in the complex interplay of engine components.
