Diesel Exhaust Fluid (DEF) is the reactant necessary for the Selective Catalyst Reduction System (SCR system) function. DEF is required for the proper after-treatment operation of your emissions system. It is a carefully blended aqueous urea solution of 30% high-purity urea and 70% deionized w...
Diesel exhaust fluid is a new approach to global emissions reduction. Learn more about DEF and what it does for your diesel engine.
DEF, short for diesel exhaust fluid, is a component in diesel engines to reduce harmful emissions and improve environmental sustainability. Diesel exhaust fluid is made from a formulated mixture of urea and deionized water and is injected into the exhaust stream of diesel vehicles that have Selectiv...
All told, diesel exhaust fluid is just as important to your vehicle as fuel, coolant, oil and all the other fluids you regularly check and replace. Your machine will not function without DEF, and you can face serious consequences from letting the DEF tank run dry. Learn moreabout T3's re...
Click here to read about after-treatment of diesel exhaust fluid (DEF) also known as AdBlue. We take a look at what diesel exhaust fluid is and why it’s needed.
the exhaust gas travels past a nozzle which sprays diesel exhaust fluid into the stream of gases. 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 ...
DEF is technically a combination of urea and deionized water. Diesel exhaust fluid (DEF) is injected into the exhaust stream, where it chemically reacts with the nitrogen oxide (NOx) gases. This reaction converts the nitrogen oxide components into nitrogen gas (inert and harmless), water vapor...
Once you’ve purchased a car that requiresdiesel exhaust fluid, the first thing you should do is open up the owner’s manual and find out what will happen if the DEF light illuminates because you’re running low.Emissions regulations in the U.S. don’t allow diesel vehicles to operate in...
High idle reduces soot in the exhaust which results from incomplete combustion at low engine revs. This is important because when diesel engines are operating at low RPMs, more soot is generated. That can fill up the diesel particulate filter (DPF) which has been installed on diesel engines si...
