Diesel Exhaust Fluid Tank
Cummins®

The Diesel Exhaust Fluid Tank (5510565) by Cummins is a component designed to store and supply Diesel Exhaust Fluid (DEF) in heavy-duty trucks. Its purpose is to facilitate the Selective Catalytic Reduction (SCR) system, which is integral to reducing emissions in diesel engines. This tank ensures a consistent supply of DEF, which is necessary for the SCR system to function effectively ¹.

Diesel Exhaust Fluid (DEF) Overview

Diesel Exhaust Fluid, commonly referred to as DEF, is a solution composed of deionized water and urea. It plays a role in reducing nitrogen oxides (NOx) emissions from diesel engines by decomposing into ammonia and carbon dioxide when introduced into the exhaust stream. The ammonia reacts with NOx in the presence of a catalyst, converting them into nitrogen and water vapor, thereby reducing harmful emissions ².

Purpose of the Diesel Exhaust Fluid Tank

This Cummins part is designed to store DEF and supply it to the SCR system. It ensures that the SCR system receives a consistent flow of DEF, which is necessary for the chemical reactions that reduce NOx emissions. The tank is engineered to maintain the integrity of DEF, ensuring it remains effective when injected into the exhaust stream ³.

Key Features

The 5510565 is constructed from materials that resist corrosion and maintain the purity of DEF. It features a robust design that enhances its durability and functionality. The tank’s capacity is sufficient to meet the demands of heavy-duty truck operations, and it includes design elements that facilitate easy refilling and maintenance ⁴.

Benefits of Using the Diesel Exhaust Fluid Tank

Using this part contributes to improved emission control, helping heavy-duty trucks comply with environmental regulations. It may also lead to potential increases in engine efficiency by ensuring the SCR system operates optimally. The tank’s design and construction support these benefits by providing a reliable source of DEF ⁵.

Installation and Integration

Proper installation of this Cummins part within the truck’s exhaust system is important for its effective operation. This may involve modifications or considerations to ensure compatibility with the truck’s existing systems. Following manufacturer guidelines during installation helps maintain the tank’s performance and durability ⁶.

Maintenance and Troubleshooting

Routine maintenance practices for the Diesel Exhaust Fluid Tank include checking for leaks, ensuring the tank is securely mounted, and verifying that the DEF supply line is free from obstructions. Troubleshooting common issues may involve inspecting the tank for signs of corrosion, ensuring the DEF quality is maintained, and addressing any leaks promptly to prevent system malfunctions ⁷.

Safety Considerations

When handling Diesel Exhaust Fluid and maintaining the Diesel Exhaust Fluid Tank, it is important to follow safety practices. This includes proper storage of DEF to prevent contamination, using protective equipment when handling the fluid, and disposing of DEF and tank components in accordance with environmental regulations ⁸.

Environmental Impact

The use of Diesel Exhaust Fluid and the Diesel Exhaust Fluid Tank plays a role in reducing the environmental impact of diesel engines by lowering NOx emissions. This contributes to cleaner air and helps meet regulatory standards aimed at reducing the carbon footprint of heavy-duty trucks ⁹.
