Diesel Exhaust Fluid Tank
Cummins®

The Diesel Exhaust Fluid Tank (Part #5417596) by Cummins is a component designed to store Diesel Exhaust Fluid (DEF), which is used in the operation of heavy-duty trucks. This tank plays a role in the emission control system by providing a reservoir for DEF, which is integral to the Selective Catalytic Reduction (SCR) system. The SCR system uses DEF to convert nitrogen oxides (NOx) into nitrogen and water, thereby reducing harmful emissions ¹.

Diesel Exhaust Fluid (DEF) Overview

Diesel Exhaust Fluid, commonly referred to as DEF, is a solution composed of deionized water and urea. It is utilized in diesel engines to reduce emissions. When DEF is injected into the exhaust stream and passes through the SCR catalyst, it decomposes into ammonia and carbon dioxide. The ammonia then reacts with NOx to form nitrogen and water, effectively lowering the emission of pollutants ².

Function of the Diesel Exhaust Fluid Tank

The Diesel Exhaust Fluid Tank operates within the SCR system to store DEF, which is periodically injected into the exhaust stream. The tank ensures a consistent supply of DEF, allowing the SCR system to function efficiently. By maintaining the DEF level, the tank contributes to the reduction of NOx emissions, enhancing the overall environmental performance of the vehicle ³.

Key Features of the 5417596 Diesel Exhaust Fluid Tank

This Cummins part is constructed from materials that offer durability and resistance to corrosion. It has a specified capacity to hold a sufficient amount of DEF for extended periods between refills. The tank includes mounting options that allow for flexible installation in various truck configurations. Additionally, it may feature design elements such as a DEF level sensor, which provides real-time data on the fluid level to the vehicle’s electronic control unit.

Benefits of Using the 5417596 Diesel Exhaust Fluid Tank

Utilizing this part offers several advantages. It contributes to improved emission control, helping vehicles meet stringent environmental regulations. The tank supports enhanced engine performance by ensuring the SCR system operates within optimal parameters. Over time, the use of this tank can lead to potential cost savings due to its durability and the efficiency it brings to the emission control process.

Installation and Integration

Proper installation of the Diesel Exhaust Fluid Tank involves integrating it with the SCR system and other related components. It is important to follow manufacturer guidelines to ensure the tank is securely mounted and connected to the DEF dosing system. Attention to detail during installation helps prevent leaks and ensures the system functions correctly.

Maintenance and Troubleshooting

Regular maintenance of the Diesel Exhaust Fluid Tank includes checking for leaks, ensuring the DEF level sensor is functioning correctly, and inspecting the tank for signs of corrosion or damage. Troubleshooting may involve addressing issues such as DEF contamination, sensor malfunctions, or connection problems. Prompt attention to these issues helps maintain the efficiency and longevity of the tank.

Environmental Impact

The use of Diesel Exhaust Fluid Tanks, like the 5417596 by Cummins, contributes to lower emissions in the trucking industry. By facilitating the SCR process, these tanks help reduce the output of NOx, a significant pollutant. This reduction in emissions supports environmental sustainability efforts and helps mitigate the impact of heavy-duty trucks on air quality.

Role of Diesel Exhaust Fluid Tank (Part 5417596) in Engine Systems

This part is integral to the Selective Catalytic Reduction (SCR) system in diesel engines. This system is designed to reduce nitrogen oxides (NOx) emissions, which are harmful pollutants. The tank stores Diesel Exhaust Fluid (DEF), a urea-based solution that is injected into the exhaust stream.

When the DEF is introduced into the exhaust, it decomposes into ammonia and carbon dioxide. The ammonia then reacts with NOx in the presence of a catalyst, converting them into harmless nitrogen and water vapor. This process significantly lowers the emission of pollutants.

The DEF tank is connected to the SCR system through a series of pipes and pumps. The level of DEF in the tank is monitored by sensors, which communicate with the engine control unit (ECU). The ECU ensures that the DEF is injected at the correct rate and timing, optimizing the reduction of NOx emissions.

Conclusion

In summary, the Diesel Exhaust Fluid Tank (Part 5417596) plays a key role in maintaining the efficiency and environmental compliance of diesel engine systems by facilitating the SCR process. Its durable construction, capacity, and integration with the SCR system make it a vital component in reducing emissions and supporting environmental sustainability efforts.
