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...
DEF is an acronym for Diesel Exhaust Fluid. Its purpose is to reduce harmful tailpipe emissions that are produced by a running diesel engine. Without DEF, diesel exhaust gases can be very harmful to the environment. DEF is technically a combination of urea and deionized water. ...
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.
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...
The DEF tank is often located right next to the diesel tank. You can tell the difference by looking at the color of the caps: Typically, the DEF tank has a blue cap, and the diesel tank has a green cap. Always double check to make sure you put the proper fluid inside the proper ...
High idle does several things. Let’s take a brief look at the purpose and benefits of using high idle on a diesel engine. Prevents Wet Stacking High idle prevents a condition known as wet stacking. This means that the temperature of the cylinder isn’t high enough to burn all the fuel...
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 the agricultural industry as a component of fertilizer...
On-board diagnostics (OBD) refers to the automotive electronic system that provides vehicle self-diagnosis and reporting capabilities for repair technicians. An OBD gives technicians access to subsystem information for the purpose of performance monitoring and analysing repair needs. OBD is the standard ...
