Product Description

What is Automotive Grade Urea?
 
Automotive-grade urea, also known as diesel exhaust fluid (DEF), is a solution
used in selective catalytic reduction (SCR) systems in diesel engines. It is designed to reduce harmful nitrogen oxide (NOx) emissions from diesel vehicles.

Automotive-grade urea is a highly purified solution of urea dissolved in demineralized water. It is non-toxic, non-flammable, and safe to handle. The urea solution is injected into the vehicle's exhaust system, where it undergoes a chemical reaction with the hot exhaust gases.

What is the negative effects of using inferior urea to produce Diesel Exhaust Fluid?

 
1. Reduced Effectiveness: Inferior urea may not have the same purity or quality standards as automotive-grade urea. This can result in a lower conversion efficiency of nitrogen oxide (NOx) emissions in the selective catalytic reduction (SCR) system. As a result, the vehicle's emissions may not be effectively reduced, potentially leading to environmental non-compliance or failing emission standards.

2. Damaged SCR System: Low-quality urea can contain impurities or contaminants that can cause damage to the SCR system components. These impurities can clog or foul the SCR catalyst, reducing its effectiveness and potentially leading to costly repairs or replacements.

3. Increased Maintenance Costs: Inferior urea can lead to more frequent clogging or malfunctioning of the SCR system, requiring more frequent maintenance and cleaning procedures. This can result in increased maintenance costs and downtime for the vehicle.
