The liquid utilized in Selective Catalytic Reduction (SCR) systems to decrease nitrogen oxide (NOx) emissions from diesel engines comprises primarily purified water and urea. This solution is carefully formulated to a specific concentration, typically around 32.5% urea, to optimize its performance within the SCR catalyst.
The effectiveness of this solution stems from its ability to convert harmful NOx gases into harmless nitrogen and water. Its implementation is crucial for meeting stringent emission standards mandated by environmental regulations worldwide. Historically, the development and widespread adoption of this fluid have significantly contributed to cleaner air and a reduction in the environmental impact of diesel-powered vehicles and equipment.
