Diesel Exhaust Fluids (DEF)
Diesel exhaust fluids (DEF) help selective catalytic reduction (SCR) diesel engines meet the EPA’s near-zero emissions standards by lowering toxic nitrogen oxide exhaust levels as a vehicle is operated. Use of this fluid is mandatory in these diesel engines operating on U.S. roads and on farmlands.
DEF is a high-pure urea solution (32.5%) and 67.5% de-ionized water that chemically changes harmful nitrogen oxide (NOx) emissions from heavy-duty diesel vehicles into harmless nitrogen and water.
