What Is Diesel Exhaust Fluid, And Who Needs It?

If you’re running a fleet on diesel, there’s a good chance your vehicles require Diesel Exhaust Fluid (DEF) to operate properly and within environmental regulations.  DEF is how modern diesel engines reduce their emissions and help keep diesel a viable option for vehicle fuel.

In this article, our Bird Fuels team wanted to briefly discuss what DEF is, how it works, and what its applications are.

What You Need to Know About Diesel Exhaust Fluid

DEF was developed based on the need to reduce harmful emissions in diesel vehicles, something which had been of growing concern.  Diesel was always among the “dirtier” fuel types, but it also generally offered better value in terms of energy storage than many other fuels.

So Selective Catalytic Reduction (SCR) was created.  SCR is a process for taking the waste byproducts of diesel and sending them through a number of catalytic processes that convert those byproducts into less-harmful versions.  SCR dissolves the most harmful gases and particles, and what comes out is almost exclusively nitrogen and water.

The technology had actually been around for a long time but only became standardized in 2010 once various governments’ regulations on vehicle emissions made diesel non-viable.

Diesel Exhaust Fluid is the key to this.  It’s a mixture of urea and de-ionized water, specifically created to trap, filter, and convert a diesel vehicle’s waste products.  By sending the exhaust through DEF, harmful emissions are reduced by up to 90%.

Keep Your Fleet Stocked with Diesel Exhaust Fluid!

Given how important DEF is for diesel vehicle operations, and staying within government regulations, it’s vital that a fleet operator always have plenty of DEF on hand for their working vehicles.  That’s where Bird Fuels can help! Our DEF delivery program can ensure you always have sufficient exhaust fluid for your vehicles, no matter the size of your fleet.
