Diesel Exhaust Fluid, often abbreviated as DEF, is a solution utilized in diesel engines equipped with Selective Catalytic Reduction (SCR) systems. Its primary function is to reduce the amount of nitrogen oxides (NOx) emitted into the atmosphere. For example, a diesel truck requires a periodic replenishment of its DEF tank to ensure continued compliance with emissions regulations.
The use of this fluid contributes significantly to environmental protection by mitigating air pollution. It assists in meeting stringent emissions standards mandated by regulatory bodies. The implementation of SCR technology and the associated need for this solution are relatively recent developments, driven by increasing concerns about air quality and the adverse effects of diesel emissions.
