Diesel Oxidation Catalysts (DOC) is one of the most reliable ways to reduce pollutants of diesel particulate emissions. DOC technology controls emissions of hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) from diesel vehicles. Our Diesel Oxidation Catalysts (DOC) is made of cordierite material, which is raw material molding and synthesized cordierite after burning. DOCâ??s channels are unimpeded, the exhaust gas can flow it smoothly, then HC, CO, PM are oxidized rapidly under the catalyst (precious metal), noxious emission are reduced effectively and reach emission standard.
