Diesel Exhaust Fluid Tank
Cummins®

The Diesel Exhaust Fluid Tank, specifically Part #5506864 by Cummins, is a component designed for modern diesel engines. It plays a role in emissions control by storing Diesel Exhaust Fluid (DEF), which is used in the Selective Catalytic Reduction (SCR) system to reduce nitrogen oxides (NOx) emissions. This tank is integral to meeting environmental regulations and improving the overall efficiency of diesel engines ¹.

Diesel Exhaust Fluid (DEF) Overview

Diesel Exhaust Fluid, commonly referred to as DEF, is a solution composed of deionized water and urea. It is utilized in the SCR system to convert NOx emissions into nitrogen and water vapor, which are less harmful to the environment. The SCR system sprays DEF into the exhaust stream, where it decomposes into ammonia. This ammonia then reacts with NOx in the presence of a catalyst, facilitating the conversion process ².
