DIESEL EXHAUST FLUID
• Diesel Exhaust Fluid (DEF) sometimes known simply by the name of its active
component, UREA—is a key component of selective catalytic reduction (SCR)
systems, which help diesel vehicles meet stringent emission regulations. DEF
is a liquid reducing agent that reacts with engine exhaust in the presence of a
catalyst to convert smog-forming nitrogen oxides (NOx) into harmless nitrogen
and water vapor.
• Your vehicle is equipped with a Selective Catalytic Reduction system in order
to meet the very stringent diesel emissions standards required by the
Environmental Protection Agency. Selective Catalytic Reduction (SCR) is the
first and only technology in decades to be as good for the environment as it is
good for business and vehicle performance.
• The purpose of the SCR system is to reduce levels of NOx (oxides of nitrogen
emitted from engines) that are harmful to our health and the environment to an
almost near-zero level. Small quantities of Diesel Exhaust Fluid (DEF) are
injected into the exhaust upstream of a catalyst where, when vaporized,
convert smog-forming nitrogen oxides (NOx) into harmless nitrogen (N2) and
water vapor (H2O), two natural components of the air we breathe. You can
operate with the comfort that your vehicle is contributing to a cleaner, healthier
world environment for this and generations to come.
