In the international standard defining DEF (ISO 22241), it is referred to as AUS 32 (aqueous urea solution 32%). DEF is also sold as AdBlue, a registered trademark of the German Association of the Automotive Industry. Several existing standards for urea for major vehicles are as follows ; 1. International Organization for Standardization ISO 22241-1:2019 Diesel engines — NOx reduction agent AUS 32...
1.Background of AdBlue In recent years, haze pollution has occurred in many places in my country, and motor vehicle exhaust emissions account for an average of 20% to 25% of the cause of haze weather. The annual national motor vehicle emissions reach 57 million tons, including nitrogen oxides, monoxide and particulate matter, of which nitrogen oxides and particulate matter emitted by automobiles e...
Automobile manufacturers are subject to various rules and these rules are increasingly being driven by environmental issues. The latest emission regulations (called Euro 6) came into effect in 2016 and pose special challenges to the development of diesel engines. Most of these require new...
The three years from 2017 have been a stage of rapid development of the automotive urea fluid industry. During this period, the National IV and National V emission regulations have been implemented successively, and the demand for automotive urea fluid has increased rapidly, driving the rapid development of the urea industry. With the advent of the National Sixth era, the a...
