DPF DOC Diesel Oxidation Catalyst 100 Cell Density Monolith - 80mm to 170mm Diameter Options with Custom Washcoat Solutions
The Diesel Oxidation Catalyst (DOC) is a critical component in diesel engine aftertreatment systems, designed to convert harmful emissions into environmentally safe compounds through advanced catalytic processes.
- Oxidizes unburned hydrocarbons (HC) and carbon monoxide (CO) into harmless water and carbon dioxide
- Converts NO in exhaust gas to NO2 for passive regeneration of downstream catalytic particulate traps (CDPF)
- Enhances NOx conversion efficiency of selective reduction catalysts (SCR)
