The Diesel Particulate Filter (DPF), with the honeycomb ceramic as its core substrate and leveraging its precise porous structure, efficiently traps soot particles (PM) emitted by diesel engines. When soot accumulates to a critical level, it can be oxidized into carbon dioxide via active regeneration (e.g., fuel-heated temperature elevation) or passive regeneration (utilizing the exhaust gas’s own high temperature). This process continuously maintains exhaust flow and particulate capture efficiency, satisfying stringent particulate emission control requirements.

This integrated system combines four core technologies: Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC), and Ammonia Slip Catalyst (ASC). It enables synergistic purification of multiple pollutants. By integrating these technologies, the system comprehensively addresses NOx, PM, CO, HC, and other contaminants, fully complying with stringent domestic and international emission regulations while ensuring systematic and efficient exhaust gas treatment for diesel engines.
