Automotive Grade Urea
Automotive Grade Urea is a solution used in the selective catalytic reduction (SCR) system of diesel vehicles to reduce harmful nitrogen oxide (NOx) emissions. It is a high-purity urea solution that is injected into the exhaust flow of a diesel engine and reacts with NOx emissions to convert it into harmless nitrogen and water vapor.
