Automotive Grade Urea

Automotive Grade Urea

Automotive grade urea is a high-quality technical grade urea that is used as a diesel exhaust fluid (DEF) to reduce nitrogen oxide (NOx) emissions from diesel engines. It is a white, solid, cylindrical pellet that contains 46% nitrogen in the form of amine groups. The use of automotive grade urea helps achieve stringent emission limits on diesel-powered engines. 

Automotive grade urea is also known as AdBlue® in Europe and is used in vehicles, construction equipment, agricultural equipment, marine vessels, and power generators. 

Uses of Automotive Grade Urea

Automotive grade urea is used as a diesel exhaust fluid (DEF) to reduce nitrogen oxide (NOx) emissions from diesel engines in vehicles such as cars, trucks, buses, and trains. In addition, it is used in construction and agricultural equipment such as tractors, harvesters, bulldozers, and irrigation pumps.
