Automotive Urea (DEF/AdBlue)
Automotive-grade urea is a specialized, high-purity urea used as a diesel exhaust fluid (DEF) to lower nitrogen oxide (NOx) emissions in diesel engines. This urea is presented as white, solid, cylindrical pellets containing 46% nitrogen in the form of amine groups. Its use is essential for meeting stringent emissions regulations for diesel-powered engines.
Also known as AdBlue® in Europe, automotive-grade urea is utilized in various sectors, including transportation (cars, trucks, buses, and trains), construction equipment, agricultural machinery, marine vessels, and power generators.
Description
Automotive Urea (DEF/AdBlue)
Automotive urea is primarily used as a DEF to reduce NOx emissions in vehicles and other equipment powered by diesel engines. Its applications extend to construction and agricultural machinery such as tractors, harvesters, bulldozers, and irrigation systems.
