Selective Catalytic Reduction Filter SCRF
SCRF system integrates selective catalytic reduction (SCR) technology coated on a diesel particulate filter (DPF). Thus, the catalyst has particulate filtering function as well as reducting function which reduces NOx to N2 and O2.
This technology has been widely used in mordern diesel engines, especially for heavy duty diesel engines.
Major reactions are:
4NH3+4NO+O2→4N2+6H2O |
2NH3+NO+NO2→2N2+3H2O |
8NH3+6NO2→7N2+12H2O |
Features:
1. SCRF has smaller dimensions and voluem.
2. Lighter in weight.
3. Cost effective.
4.Can closed coupled with DOC.
5. Its compact structure improves SCR performance at cold start and low temperature exhaust.
