Product Description
DPF

💡 DPF INTRODUCTION

DPF is the only option to satisfy particle number emissions. Support materials include ceramics, aluminum titanate, and silicon carbide. Our coating technologies are based on a high thermal stable wash coat formulation with excellent NO2 formation.

⚙️ DOC INTRODUCTION

DOC oxidizes unburned hydrocarbons (HC) and carbon monoxide (CO) into water and carbon dioxide. It also converts NO into NO2 for passive regeneration of downstream CDPF and improves NOx conversion efficiency of SCR systems.

DOC
Working Principle of DOC + CDPF
Working Principle
  • 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.
  • Continuous Utilization: NO produced is re-oxidized to NO2 for ongoing particle reaction.
Product Advantages
  • Excellent thermal shock resistance
  • Unique cellular designs reducing vortex
  • Accurate extrusion for stable quality
  • Obvious filtration efficiency
  • Improved casting surface performance
  • Prolonged working life of components
  • Stable chemical composition
  • Precise dimension for auto-mounting
