Diesel Oxidation Catalyst（DOC）： It is a structure coated with an oxidized noble metal catalyst coating on the surface of a honeycomb shaped ceramic carrier. It can oxidize most of the carbon monoxide (CO), hydrocarbons (CH), and most of the soluble organic matter (SOF) in particulate matter (PM) in tail gas. The conversion efficiency of DOC for CH and CO is about 80% -90%, and the reaction efficiency for SOF is about 30%. And the oxidation reaction process will generate a large amount of heat, providing the required reaction temperature for SCR reaction or passive regeneration of CDPF.

Diesel Particulate Filter （DPF）： It is currently considered the most effective and technologically mature device for reducing PM emissions. DPF utilizes inertial collision, interception, diffusion, and gravity settling mechanisms to filter PM out of exhaust gas. The capture efficiency of DPF for PM in exhaust gas can reach about 95%.

Selective Catalytic Reduction Agent (SCR): SCR is a structure coated with a selective reduction catalyst coating on the surface of a honeycomb shaped ceramic carrier. The reducing agent (NH3) sprayed by the device system reacts rapidly with nitrogen oxides (NOX) in the exhaust gas under the action of catalyst coating, thereby reducing NOX emissions in the exhaust gas. The conversion efficiency of SCR to NOX can reach over 90%.
