Product description：

• DOC Material: Ceramic

• DPF Material: Silicon Carbide (SiC)

• Compatibility: Diesel engines (trucks, heavy machinery, and other applications)

• Installation: Engine exhaust system

Dpf size: 144*127mm

DOC size:144*76.2mm

The package includes: 1pcs DPF+1cps doc +2pcs Insulation cotton

Working Principles and Benefits:

DOC (Diesel Oxidation Catalyst):

• Utilizes a ceramic structure with a platinum coating to oxidize carbon monoxide (CO) and hydrocarbons (HC) into less harmful carbon dioxide (CO₂) and water (H₂O).

• Efficiently reduces toxic emissions while maintaining engine performance.

DPF (Diesel Particulate Filter):

• The Silicon Carbide material provides excellent durability and filtration efficiency to capture soot and particulate matter (PM) from diesel exhaust.

• Offers a high melting point and thermal shock resistance for long-lasting use.
