Diesel Exhaust Fluid (DEF) is an aqueous urea solution used in Selective Catalytic Reduction (SCR) systems on diesel vehicles to reduce nitrogen oxide (NOx) emissions. It’s a crucial component in meeting stringent emission standards mandated by environmental regulations. The implementation of this technology represents a significant step towards cleaner air quality.
The widespread adoption of this fluid correlates directly with increasingly strict emissions regulations globally. These regulations, aimed at lowering NOx emissions from diesel engines, drove manufacturers to incorporate SCR systems into their vehicles. The introduction of SCR technology, requiring this specific fluid, became essential for compliance. This shift marked a notable change in diesel engine technology and maintenance.
