Core Technology Introduction
DPF Introduction: The only option to satisfy particle number emissions. Support materials include ceramics, aluminum titanate, and silicon carbide.
DOC Introduction: Oxidizes unburned hydrocarbons (HC) and carbon monoxide (CO) into water and CO2. Essential for SCR efficiency.
Working Principle of DOC + CDPF
⚙️
DOC: Oxidation of NO to NO2 and removal of CO and HC.
CDPF: Captured carbon particles react with NO2 at low temperature to produce CO2 emissions for continuous regeneration.
Product Advantages
- Excellent thermal shock resistance.
- Unique cellular designs reducing vortex and bubbles.
- Accurate extrusion die for stable quality and consistency.
- Improving casting surface performance and density.
- Good chemical stability, unaffected by melted metal.
- Precise dimension for automatic filter mounting lines.
