Automotive Diesel Exhaust Fluid (DEF) is a solution made from urea and deionized water that is used in diesel engines to reduce harmful emissions. When DEF is injected into the exhaust stream of a diesel vehicle, it breaks down harmful nitrogen oxides into harmless nitrogen and water vapor. This process helps diesel engines meet stringent emissions regulations, such as the EPA's Tier 4 standards. Automotive DEF is typically stored in a separate tank on the vehicle and is consumed at a rate relative to fuel consumption.
The market for Automotive Diesel Exhaust Fluid is experiencing steady growth due to increasing environmental regulations aimed at reducing vehicle emissions. As governments worldwide implement stricter emission standards, the demand for DEF is expected to rise. In addition,
