The Exhaust Outlet Tube (4995148) is specifically engineered to fit the ISB6.7 CM2250 and ISB6.7 CM2350 B101 engines. These engines are known for their robust performance and reliability, often used in heavy-duty applications such as commercial trucks and industrial machinery. The part ensures that the exhaust gases are directed efficiently from the turbocharger to the exhaust manifold, maintaining optimal pressure and flow.

QSB6.7 CM2250 and QSB6.7 CM2350 B105

Similarly, the Exhaust Outlet Tube (4995148) is also compatible with the QSB6.7 CM2250 and QSB6.7 CM2350 B105 engines. These engines are designed for versatility, finding use in a range of applications from agricultural equipment to construction machinery. The part’s design ensures that the exhaust system operates smoothly, reducing back pressure and enhancing the engine’s efficiency.

Common Features Across Engines

While the specific applications of these engines may vary, the Exhaust Outlet Tube (4995148) serves a common purpose across all models. It is crafted to withstand high temperatures and pressures, ensuring durability and reliability. The tube’s precise fit and construction are critical for maintaining the integrity of the exhaust system, which in turn affects the engine’s overall performance and emissions control.

Role of Part 4995148 Exhaust Outlet Tube in Engine Systems

The Exhaust Outlet Tube, identified by part number 4995148, is an integral component in the efficient operation of engine systems, particularly in those equipped with Exhaust Recirculation (EGR) and Water Plumbing systems.

In EGR systems, the Exhaust Outlet Tube facilitates the redirection of a portion of the exhaust gases back into the intake manifold. This process reduces nitrogen oxides (NOx) emissions by lowering the combustion temperature within the cylinders. The tube ensures a controlled flow of these gases, maintaining engine performance while meeting environmental regulations.

When integrated with water plumbing systems, the Exhaust Outlet Tube plays a significant role in cooling the recirculated exhaust gases. Water is injected into the exhaust stream, which helps in reducing the temperature of the gases before they are reintroduced into the intake system. This cooling effect is vital for protecting sensitive engine components from thermal stress and enhancing overall engine durability.

Furthermore, the Exhaust Outlet Tube contributes to the maintenance of optimal backpressure within the exhaust system. Proper backpressure is essential for efficient combustion and effective operation of the turbocharger, if present. The tube’s design ensures that the exhaust flow is managed correctly, supporting both the EGR and water plumbing systems in their respective functions.

Conclusion

The Exhaust Outlet Tube 4995148 by Cummins is a critical component in the exhaust systems of heavy-duty trucks, designed to enhance engine performance and efficiency. Its role in managing exhaust gas flow, supporting EGR and water plumbing systems, and maintaining optimal backpressure is fundamental to the engine’s operation and emission control. Regular maintenance and proper installation are key to ensuring the longevity and reliability of this Cummins part.
