Diesel Exhaust Fluid Tank
Cummins®

The Diesel Exhaust Fluid Tank (Part #5417595) by Cummins is a component designed for use in heavy-duty trucks. Its purpose is to store Diesel Exhaust Fluid (DEF), which is utilized in the Selective Catalytic Reduction (SCR) system to reduce nitrogen oxides (NOx) emissions. This part plays a role in the overall operation of the truck by ensuring the SCR system has a consistent supply of DEF, thereby contributing to the truck’s emission control capabilities.

Diesel Exhaust Fluid (DEF) Overview

Diesel Exhaust Fluid, commonly referred to as DEF, is a solution composed of deionized water and urea. It is employed in diesel engines to reduce emissions. When DEF is injected into the exhaust stream and heated, it decomposes into ammonia and carbon dioxide. The ammonia then reacts with NOx in the presence of a catalyst, converting them into nitrogen and water vapor, which are less harmful to the environment ¹.

Function of the Diesel Exhaust Fluid Tank

The Diesel Exhaust Fluid Tank operates within the SCR system by storing DEF. As the engine runs, the SCR system draws DEF from this Cummins part to inject into the exhaust stream. This process facilitates the chemical reaction that reduces NOx emissions. The tank is designed to maintain a sufficient supply of DEF to ensure the SCR system functions effectively throughout the truck’s operation.

Key Features of the Cummins 5417595 Diesel Exhaust Fluid Tank

The Cummins 5417595 Diesel Exhaust Fluid Tank is constructed from materials that offer durability and resistance to the corrosive nature of DEF. It features a design that maximizes capacity while minimizing the risk of leaks. Additionally, the tank includes elements such as a DEF level sensor and a secure fitting system to enhance its performance and ensure compatibility with various engine models and SCR systems.

Benefits of Using the Cummins 5417595 Diesel Exhaust Fluid Tank

Utilizing the Cummins 5417595 Diesel Exhaust Fluid Tank provides several advantages. It contributes to improved emission control by ensuring a consistent supply of DEF to the SCR system. This helps in meeting environmental regulations regarding emissions. Furthermore, efficient emission control can lead to potential increases in engine efficiency, as the SCR system operates optimally with a reliable DEF supply ².

Installation and Integration

Proper installation of the Cummins 5417595 Diesel Exhaust Fluid Tank involves ensuring compatibility with the truck’s engine model and SCR system. It is important to follow manufacturer guidelines for integration to avoid issues such as leaks or inefficient DEF delivery. The tank should be securely mounted and connected to the SCR system to ensure it functions as intended.

Maintenance and Troubleshooting

Routine maintenance of the Cummins 5417595 Diesel Exhaust Fluid Tank includes checking for leaks, monitoring DEF levels, and ensuring the tank and its connections are free from debris or obstructions. Troubleshooting common issues may involve inspecting the DEF level sensor and ensuring the tank is properly sealed. Regular maintenance helps in maintaining the tank’s performance and longevity.

Environmental Impact

The use of Diesel Exhaust Fluid Tanks, like the Cummins 5417595, contributes to reduced air pollution by enabling the SCR system to effectively lower NOx emissions. This aligns with compliance to emissions standards and supports efforts to minimize the environmental impact of heavy-duty trucks.

Role of Diesel Exhaust Fluid Tank (Part 5417595) in Engine Systems

The Diesel Exhaust Fluid Tank (DEF Tank), identified by part number 5417595, is an integral component in modern diesel engine systems, specifically within the Selective Catalytic Reduction (SCR) system. This tank stores the Diesel Exhaust Fluid (DEF), also known as AdBlue, which is a solution of urea and deionized water. The DEF is injected into the exhaust stream where it decomposes into ammonia and carbon dioxide.

In the SCR system, the DEF interacts with the exhaust gases passing through the catalyst. The ammonia produced from the DEF reacts with nitrogen oxides (NOx) in the exhaust, converting them into harmless nitrogen and water vapor. This process significantly reduces the emissions of NOx, which are harmful pollutants ³.

The DEF Tank is connected to the DEF dosing system, which includes the DEF pump, injector, and various sensors. The tank supplies DEF to the pump, which then pressurizes the fluid before it is injected into the exhaust stream by the injector. Sensors monitor the DEF level and quality, ensuring that the system operates efficiently and that the DEF is of the correct concentration.

Additionally, the DEF Tank is part of a larger network that includes the Engine Control Unit (ECU). The ECU receives data from the DEF system sensors and adjusts the injection rate of DEF based on engine load, temperature, and other operating conditions. This ensures optimal performance and emission control under varying driving conditions.

Conclusion

In summary, the DEF Tank (part 5417595) plays a significant role in maintaining the efficiency and environmental compliance of diesel engine systems by storing and supplying DEF to the SCR system, which is essential for reducing NOx emissions.
