About automotive-grade urea

Automotive-grade urea dissolved within deionized water is resulting in an aqueous urea solution, supporting the reduction of mono-nitrogen oxides exhaust emissions by injection into selective catalytic reduction systems of heavy-duty engines. This aqueous urea solution is standardized as AUS 32 in ISO 22241 and consequently, the technical specifications for automotive-grade urea are derived from this standard. Mainly with the introduction of new regulations and standards in connection to emissions (e.g. EURO 5 norm), the demand for AUS 32 and consequently automotive-grade urea is increasing constantly.
