What Is The DEF (Diesel Exhaust Fluid) System?

Do you manage a fleet of commercial vehicles in Palm Beach or one of the surrounding areas? If so, then you’re well aware of the responsibilities on your shoulders, from vehicle maintenance to managing insurance costs. Because of this, addressing emissions might not always be a top priority. However, Diesel Exhaust Fluid (DEF) is an essential consideration for diesel fleets, as it can reduce nitrogen dioxide emissions as you carry out business operations in the greater Orlando area.

In 2010, the Environmental Protection Agency mandated selective catalytic reduction (SCR) systems, which significantly altered operations for long-haul truckers and diesel engine enthusiasts in Ft Lauderdale and beyond. This SCR system is a solution to reduce diesel engine emissions, and its function relies on Diesel Exhaust Fluid (DEF).

What Is DEF Made Of?

Diesel Exhaust Fluid (DEF) is an automotive-grade solution consisting of deionized water and urea. It is introduced into a diesel engine’s exhaust stream to trigger a chemical reaction that converts harmful nitrogen oxides (NOx) into harmless nitrogen and water. This process is essential for preventing the release of dangerous gases, byproducts of diesel engine operation, into the environment.

What Is The SCR System?

Selective catalytic reduction is the emissions control technology that uses DEF to start the chemical reaction. Once the reaction takes place and converts oxides of nitrogen, the tailpipe emits more environmentally friendly nitrogen, water, and some carbon dioxide.
