SCRF (Selective Catalytic Reduction Filter) is a method of coating SCR catalyst into a wall flow particulate trap, achieving dual catalytic functions of SCR and DPF, and reducing NO emissions_xAnd PM/PN emissions. The compact structural layout helps to quickly increase the catalyst bed temperature and improve the SCR catalytic efficiency during the cold start stage. Mainly applicable to road diesel engines with national VI and above emission standards.

The system has a small volume, light weight, and flexible and convenient design and installation.
Has good PM/PN capture capability.
