Diesel exhaust fluid (DEF; also known as AUS 32 and marketed as AdBlue) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water.
Diesel Exhaust Fluid (DEF) is a non-toxic, high purity solution comprised of 32.5% urea and 67.5% de-ionized water for specific use in Selective Catalytic Reduction (SCR) systems. Using this fluid in diesel-powered vehicles, such as trucks, buses, and tractors, helps to reduce the amount of nitrogen oxides (NOx) emitted into the air by 90%.
15 sie 2023 · Modern diesel engines use Diesel Exhaust Fluid (DEF) or AdBlue in selective catalytic reduction (SCR) systems to address this concern and minimize NOx emissions. In this article, we will look in-depth at the Diesel Exhaust Fluid Composition and how it aids in curbing harmful emissions.
27 gru 2023 · What Is DEF Fluid Made of? Diesel Exhaust Fluid (DEF) which is composed of 32.5 percent urea and 67.5 percent deionized water. For those who like trivia, urea is considered to be the first organic compound to be synthesized from inorganic chemicals.
The active ingredient in DEF, urea, has been chemically synthesized since 1828 first by German scientist Friedrich Wöhler after treating silver cyanate with ammonium chloride. Urea was first discovered in urine by Dutch chemist Herman Boerhaave in 1727.
DEF is designed for use in diesel engines with SCR technology. This package will provide for approximately 16,500 miles (your results may vary depending on your vehicle and dosage rate). Chemical Data Meets AUS 32, ISO 22241, and DIN 70070 Specification Weight- 9.1 lbs per gallon (1.09 kg per liter) 32.5% automotive grade urea/Dl water Clear
11 sty 2024 · DEF is a clear, non-toxic, and highly purified liquid composed of 32.5% urea and 67.5% deionized water. It’s specifically formulated for use in SCR systems, which are designed to reduce the amount of harmful nitrogen oxides (NOx) emitted by diesel engines.
