Cummins®

The Diesel Exhaust Fluid Tank 4387618 by Cummins is a component designed to store Diesel Exhaust Fluid (DEF), which is used in the Selective Catalytic Reduction (SCR) system of heavy-duty trucks. This part plays a role in the emission control system by providing a reservoir for DEF, which is injected into the exhaust stream to reduce nitrogen oxides (NOx) emissions.

Basic Concepts of Diesel Exhaust Fluid Tanks

A Diesel Exhaust Fluid (DEF) tank is a storage unit for DEF, a solution of urea and deionized water. In the SCR system, DEF is sprayed into the exhaust stream where it decomposes into ammonia and carbon dioxide. The ammonia then reacts with NOx in the presence of a catalyst, converting them into nitrogen and water vapor, which are less harmful to the environment ¹. This process is integral to meeting stringent emission standards.

Purpose of the 4387618 Diesel Exhaust Fluid Tank

The 4387618 Diesel Exhaust Fluid Tank is designed to store DEF and supply it to the SCR system in heavy-duty trucks. It ensures a consistent and reliable source of DEF, which is necessary for the effective reduction of NOx emissions. The tank is engineered to integrate seamlessly with the truck’s exhaust system, contributing to overall emission control and compliance with environmental regulations ².

Role of Part 4387618 Diesel Exhaust Fluid Tank in Engine Systems

The Diesel Exhaust Fluid (DEF) tank, specifically part 4387618, is integral to the operation of modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems. This tank stores DEF, a solution of urea and deionized water, which is essential for reducing nitrogen oxides (NOx) emissions.

When the engine is running, DEF is injected into the exhaust stream upstream of the SCR catalyst. Here, the urea in the DEF decomposes into ammonia and carbon dioxide. The ammonia then reacts with NOx in the presence of the SCR catalyst, converting them into harmless nitrogen and water vapor.

The DEF tank is connected to the DEF dosing system, which includes the DEF pump, injector, and associated tubing. The pump draws DEF from the tank and delivers it to the injector, which meters the precise amount needed based on engine load and exhaust temperature.

The DEF level sensor, typically integrated within the tank, monitors the fluid level and communicates with the engine control unit (ECU). The ECU uses this data to ensure the DEF supply is adequate for continued operation and to alert the driver if the DEF level is low.

In summary, part 4387618 Diesel Exhaust Fluid Tank is a key component in the emissions control system of diesel engines, ensuring compliance with environmental regulations and maintaining efficient engine performance.

Conclusion

The 4387618 Diesel Exhaust Fluid Tank by Cummins is a vital component in the emission control system of heavy-duty trucks. It ensures a consistent supply of DEF to the SCR system, facilitating the reduction of NOx emissions and helping to meet stringent environmental regulations.
