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. Discover brake fluids, automotive greases & lubricants, refrigerants & more. Get deals and low prices on Def Liquid For Diesel at Amazon Diesel exhaust fluid (also referred to as DEF or AUS 32) is injected into the diesel exhaust stream and the heat from the exhaust, the fluid, and a catalyst convert the NOx into the harmless gases. Diesel exhaust fluid is a 32.5% solution of technically pure urea in purified water. · Diesel Exhaust Fluid (DEF), also known as AUS 32 or AdBlue, is a non-toxic, clear, and colorless liquid composed of 32.5% high-purity urea and 67.5% deionized water. It’s not a fuel additive, instead, it's stored in a separate tank in vehicles equipped with Selective Catalytic Reduction (SCR) systems. DEF, also known as AdBlue or AUS32 (aqueous urea solution 32.5%), is a specially formulated solution that is injected into the exhaust stream of diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology. · When you mix urea and water together just right, you get a clear liquid called dieselexhaustfluid, or DEF. AUS32 is the most common type of DEF used all over the world. So, think of AUS32 as a helper juice for big diesel trucks. It doesn’t go into the engine like gas or diesel. · AUS 32 is an acronym for Aqueous Urea Solution with 32.5% urea, otherwise known as diesel exhaust fluid. AUS 32 is 32.5% by weight pure grade urea dissolved in 67.5% pure water. AUS 32 is also known as Transit DEF and is the most commonly used DEF type and concentration. Our AUS32 DEF transforms harmful nitrogen oxide (NOx) emissions from diesel powered vehicles into harmless water vapour and nitrogen. It is a 32.5% (AUS32) Aqueous Urea Solution produced with high-purity urea mixed with demineralized water and was formulated to meet the specifications of ISO 22241- 1:2019.
