Introduction

The Cummins 5418338 Diesel Exhaust Fluid Tank 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 emissions control system by providing a reservoir for DEF, which is injected into the exhaust stream to reduce nitrogen oxides (NOx) emissions ¹.

Basic Concepts of Diesel Exhaust Fluid Tanks

A Diesel Exhaust Fluid (DEF) tank is a storage unit for DEF, a solution composed of urea and deionized water. Within 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 to form nitrogen and water vapor, effectively reducing harmful emissions. DEF is typically composed of 32.5% high-purity urea and 67.5% deionized water ².

Role of the 5418338 Diesel Exhaust Fluid Tank in Truck Operation

The 5418338 Diesel Exhaust Fluid Tank integrates into the truck’s emissions control system by providing a dedicated storage space for DEF. This tank ensures a consistent supply of DEF to the SCR system, which is crucial for the reduction of NOx emissions. The tank is designed to withstand the conditions within the truck’s undercarriage, ensuring reliable performance over time ³.

Key Features of the 5418338 Diesel Exhaust Fluid Tank

The 5418338 Diesel Exhaust Fluid Tank is constructed from durable materials to resist corrosion and maintain integrity under varying temperatures and conditions.
