Diesel Exhaust Fluid Tank
Cummins®

The Cummins 4387616 Diesel Exhaust Fluid Tank is a component designed for commercial trucks, playing a role in the reduction of emissions. It is part of the Selective Catalytic Reduction (SCR) system, which is integral to modern diesel engines for meeting stringent environmental regulations ¹.

Basic Concepts of Diesel Exhaust Fluid Tanks

A Diesel Exhaust Fluid (DEF) tank stores the fluid used in the SCR system. This system reduces nitrogen oxides (NOx) emissions by injecting DEF into the exhaust stream, where it reacts with NOx to form harmless nitrogen and water vapor. DEF is primarily composed of urea and deionized water ².

Purpose and Role in Truck Operation

This Cummins part is designed to store DEF, which is crucial for the SCR system’s operation. By providing a consistent supply of DEF, the tank helps in the chemical reaction that reduces NOx emissions, allowing trucks to comply with environmental regulations and operate more cleanly.

These engines, while differing in size and power output, share the same foundational design that allows for the integration of the Cummins Diesel Exhaust Fluid Tank part number 4387616.

Ensuring Proper Fitment

When installing the 4387616, it is crucial to verify the part number against the engine specifications. This ensures that the tank is correctly sized and positioned for optimal performance and compatibility with the SCR system. Proper installation and maintenance of this component are essential for maintaining emission standards and engine efficiency.

Role of 4387616 Diesel Exhaust Fluid Tank in Engine Systems

The Diesel Exhaust Fluid (DEF) tank, identified by part number 4387616, is integral to the Selective Catalytic Reduction (SCR) system found in modern diesel engines. This system is designed to reduce nitrogen oxides (NOx) emissions, which are harmful pollutants. The DEF tank stores the fluid, commonly known as AdBlue, which is a urea-based solution.

When the engine control unit (ECU) detects that the exhaust gas temperature and flow rate are optimal, it signals the DEF dosing module to inject a precise amount of DEF into the exhaust stream upstream of the SCR catalyst. The DEF then decomposes into ammonia and carbon dioxide. As the exhaust gases pass through the SCR catalyst, the ammonia reacts with NOx to form harmless nitrogen and water vapor.

The DEF tank is connected to the DEF dosing module via a series of hoses and pipes. These connections ensure a consistent and controlled flow of DEF to the injection point. The tank is also equipped with a level sensor that monitors the DEF quantity. This sensor communicates with the ECU, which can alert the driver when the DEF level is low, ensuring that the SCR system operates efficiently and effectively.

Conclusion

In summary, the DEF tank plays a significant role in maintaining the efficiency of the SCR system, ensuring that diesel engines meet stringent emission standards while optimizing performance.
