Diesel Exhaust Fluid Tank
Cummins®

The Diesel Exhaust Fluid Tank (Part #5418341) by Cummins is a component designed for use in commercial 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. These compounds then react 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 Selective Catalytic Reduction system by storing DEF. As the engine runs, the SCR system draws DEF from the tank to mix with the exhaust gases. This mixture passes through a catalyst, where the chemical reaction takes place to convert NOx into nitrogen and water vapor. The tank ensures a steady supply of DEF is available for this process, maintaining the efficiency of the emission reduction system.

Key Features of the Cummins Diesel Exhaust Fluid Tank

This Cummins part is constructed from materials that offer durability and resistance to the corrosive nature of DEF. It is designed with a specific capacity to hold an adequate amount of fluid for extended periods between refills. The tank includes design elements such as a secure fitting for the DEF supply line and a level sensor to monitor fluid levels, enhancing its performance and ensuring it can withstand the demands of commercial truck operations.

Benefits of Using the Cummins Diesel Exhaust Fluid Tank

Utilizing the Cummins Diesel Exhaust Fluid Tank offers several advantages. It contributes to improved emission control, helping trucks meet stringent environmental regulations. The tank’s design and construction support enhanced engine performance by ensuring the SCR system operates efficiently. Additionally, the use of this part can lead to better fuel economy and reduced maintenance costs over time.

Installation and Integration

Proper installation of the Diesel Exhaust Fluid Tank involves ensuring compatibility with the truck’s make and model and integrating it with the SCR system. Installation guidelines recommend following manufacturer specifications to secure the tank in place and connect it to the DEF supply line and level sensor. Careful attention to these steps ensures the tank functions correctly within the emission control system.

Maintenance and Troubleshooting

Routine maintenance of the Diesel Exhaust Fluid Tank includes checking for leaks, inspecting the level sensor, and ensuring the DEF supply line is free from obstructions. Troubleshooting may involve addressing issues such as low DEF levels, sensor malfunctions, or supply line blockages. Regular maintenance and prompt troubleshooting help ensure the longevity and efficient operation of the tank.

Common Issues and Solutions

Common problems associated with Diesel Exhaust Fluid Tanks include leaks, contamination of DEF, and sensor failures. Solutions to these issues may involve replacing damaged components, flushing the tank to remove contaminants, or calibrating or replacing the level sensor. Addressing these problems promptly can prevent more significant issues and maintain the tank’s performance.

Environmental Impact

The use of Diesel Exhaust Fluid Tanks in commercial trucks contributes to reducing harmful emissions, particularly NOx, which is a precursor to smog and acid rain. By facilitating the SCR system’s operation, these tanks play a role in promoting cleaner air quality and mitigating the environmental impact of diesel engines ².
