What is Diesel Exhaust Fluid (DEF)

Diesel Exhaust Fluid (DEF) is a solution composed of 32.5% urea, designed for use in diesel-powered vehicles and equipment with Selective Catalytic Reduction (SCR) systems. Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NOx with the aid of a catalyst into diatomic nitrogen (N2), and water (H2O).
When injected into the exhaust system, DEF helps reduce harmful nitrogen oxide (NOx) emissions by converting them into harmless nitrogen and vapor. This process ensures compliance with environmental regulations, improves air quality, and boosts engine efficiency.

Reduced Emissions

The amount of NOx in the exhaust gas can be reduced by 85–95%.

How DEF Helps Your Engine Run Clean

(Breaking Down the Science Behind DEF and Emission Control)

DEF is a critical part of modern diesel engines’ emission-control systems. As a high-purity solution of urea and water, DEF is injected into the exhaust stream where it works with Selective Catalytic Reduction (SCR) technology. When DEF reacts with nitrogen oxides (NOx) in the exhaust gases, it transforms them into safe nitrogen and water vapor, reducing harmful emissions. This not only ensures your diesel vehicles meet emission regulations but also promotes a cleaner, healthier environment.
