NOₓ is a harmful pollutant that contributes to smog and acid rain. #marineengineering | Mhark Christian Cenaon | Facebook

Selective Catalytic Reduction (SCR) 🚗🚘⛽is an advanced active emissions control technology system that reduces tailpipe emissions of nitrogen oxides (NOx) down to near-zero levels in newer generation diesel-powered vehicles and equipment. The SCR system involves several components packaged together with other parts of the emissions control system. Each manufacturer has its own variations of the type and sequencing of different components in the system. How does work SCR is an active emissions c
