What is DEF?
DEF, or diesel exhaust fluid, is used in a selective catalytic reduction (SCR) system to remove nitrogen oxides (NOx) from engine exhaust. The main components of the SCR system include the SCR catalyst, the DEF injector, the DEF tank, and the DEF supply module and filter. DEF is injected into the exhaust stream prior to the SCR catalyst. NOx in the exhaust stream is then converted into harmless nitrogen and water through a chemical reaction.
DEF is 32.5 percent DEF-grade urea and 67.5 percent demineralized water. This ratio provides the lowest possible freeze point.
DEF is also: Colorless, Nonflammable, Nontoxic, Slightly corrosive, 9.1 lb./gal.
Many names and terms are used for DEF: Urea, Aqueous urea solution - AUS32®*, AdBlue®**, NOx reduction agent – ARLA 32TM, Diesel exhaust fluid
Diesel Exhaust Fluid Quick Tips
- Compatible with all engines using selective catalytic reduction (SCR) after-treatment technology
- Always store in sealed containers away from extreme temperatures
- When stored properly, expect a shelf life comparable to oils and coolants
- Purchase in amounts that can be used in a reasonable length of time
- Use only approved compatible equipment when handling DEF
- DEF is crystal clear with a light ammonia smell. It should not be used if it is cloudy or has a colored tint or a profound ammonia smell
