The diesel exhaust fluid (DEF) tank is a separate reservoir in vehicles equipped with selective catalytic reduction (SCR) systems. It is specifically designed to store and supply DEF to the SCR system for emission control purposes. It is a mixture of urea and deionized water. When injected into the exhaust stream, DEF undergoes a chemical reaction with the nitrogen oxides (NOx) present in the exhaust, converting them into harmless nitrogen and water vapor.Attributes:• Designed to handle pressures up to 3Psi• Manufactured to precise specifications and are built for durability and reliability• Helps to break down the NOx emissions into less harmful componentsApplications:The Diesel Exhaust Fluid (DEF) is a solution used in modern trucks to reduce harmful emissions from the exhaust gases produced by diesel engines.
