Passenger car using an AdBlue pump. Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue[3]) 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.
To comply with cutting down emission levels, diesel engine manufacturers as a whole decided to implement a selective catalytic reduction (SCR) system, which includes an SCR catalyst, a pump, a tank, lines, an injector, and a synthetic, non-toxic diesel exhaust fluid (DEF).
Since around 2002, SCR (Selective Catalytic Reduction) systems that use Diesel Exhaust Fluid (DEF) made their appearance in the automotive market. So what’s in DEF? DEF is a solution (or mixture) of 32.5% Urea and 67.5% de-ionised water.
3 Οκτ 2024 · What Is DEF? Diesel exhaust fluid is an automotive-grade combination of urea and deionized water, which you inject into the exhaust stream of a diesel engine to help turn NOx, or oxides of...
What is Diesel Exhaust Fluid (DEF) Made of? Diesel Exhaust Fluid is created from about two parts deionized water – highly purified H2O – and one part urea –often used in fertilizers. Urea is also a compound found in urine, although it is not urine in the DEF form.
1 Μαΐ 2024 · While DEF (Diesel Exhaust Fluid) is a special fuel. It is actually a crucial partner in a technology, Selective Catalytic Reduction (SCR) that significantly reduces harmful emissions from modern diesel engines. Let us break down what DEF is for and how does Diesel Exhaust Fluid work with SCR: DEF: The Chemical Catalyst
30 Ιουλ 2021 · DEF is made from deionized water and a very pure form of urea. Yes, urea is found in urine -- quit giggling, please -- but this is a refined form of the compound and is mostly used in the...
