The Cummins 4387613 Diesel Exhaust Fluid Tank is a component designed for use in heavy-duty trucks. It serves a specific function within the vehicle’s emissions control system, contributing to the overall operation and efficiency of the truck. This tank is integral to the Selective Catalytic Reduction (SCR) system, playing a role in reducing harmful emissions produced by diesel engines ¹.

Basic Concepts of Diesel Exhaust Fluid Tanks

A Diesel Exhaust Fluid (DEF) tank is a reservoir that stores DEF, a solution of urea and deionized water. This fluid is injected into the exhaust stream where it decomposes into ammonia and carbon dioxide. The ammonia then reacts with nitrogen oxides (NOx) in the presence of a catalyst, converting them into nitrogen and water vapor. This process is known as Selective Catalytic Reduction (SCR) and is a key method for reducing emissions in diesel engines ².

Purpose of the Cummins 4387613 Diesel Exhaust Fluid Tank

The Cummins 4387613 Diesel Exhaust Fluid Tank is designed to store DEF, which is used in the SCR system to reduce NOx emissions. By providing a dedicated storage solution, this tank ensures that the SCR system has a consistent supply of DEF, enabling it to operate effectively. This, in turn, contributes to lower emissions and helps the truck meet environmental regulations ¹.

Integration of Part 4387613 Diesel Exhaust Fluid Tank in Engine Systems

The Diesel Exhaust Fluid (DEF) tank, specifically part 4387613, is an integral component in modern diesel engine systems, designed to work in conjunction with the Selective Catalytic Reduction (SCR) system. This tank stores DEF, 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.

When the exhaust gases pass through the SCR catalyst, the ammonia reacts with nitrogen oxides (NOx) to form harmless nitrogen and water vapor. The DEF tank is connected to the DEF dosing module via a supply line. The dosing module, in turn, is electronically controlled by the Engine Control Unit (ECU) to meter the precise amount of DEF needed based on engine load, exhaust temperature, and other operating conditions.

The DEF tank also features a level sensor that communicates with the ECU to monitor the fluid level. This information is vital for ensuring that the SCR system operates efficiently and that the vehicle complies with emissions regulations. In the event of low DEF levels, the ECU will trigger a warning to the driver, and continued operation without adequate DEF can lead to reduced engine performance or even de-rated power to prevent damage to the aftertreatment system.

In summary, the DEF tank, as part of the SCR system, plays a significant role in reducing emissions from diesel engines, ensuring they meet environmental standards while maintaining engine performance ².

Conclusion

The Cummins 4387613 Diesel Exhaust Fluid Tank is a critical component in the emissions control system of heavy-duty trucks. It ensures the SCR system has a consistent supply of DEF, contributing to lower emissions and compliance with environmental regulations. Proper installation, maintenance, and understanding of its role in the SCR system are essential for optimal performance and regulatory compliance ¹²³.
