DPF Filter Core

DPF INTRODUCTION

DPF is the only option to satisfy particle number emissions. Common DPF support materials are ceramics, aluminum titanate and silicon carbide. The choice of carrier material is mainly based on the use of DPF and regeneration strategy, including carbon back pressure, filtration efficiency, regeneration temperature, time and so on. Our DPF coating technologies are based on a high thermal stable wash coat formulation with excellent NO2 formation.

DOC Catalyst

DOC INTRODUCTION

DOC is one of the most important catalysts for diesel engine reprocessing. Its main function is to oxidize the unburned hydrocarbons (HC) and carbon monoxide (CO) into harmless water and carbon dioxide. At the same time, it converts NO into NO2 for passive regeneration of downstream catalyst particle trap (CDPF) and improves NOx conversion efficiency of SCR.

Working Principle of DOC + CDPF
Working Principle 1
Working Principle 2
  • 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.
  • Continuous Utilization: The NO produced by the reaction of NO2 with carbon particles is oxidized to NO2 again for ongoing reaction.
Key Advantages
  • Excellent thermal shock resistance.
  • Unique cellular designs reducing liquid vortex and bubbles during casing.
  • Accurate extrusion die for stable and consistent quality.
  • Obvious and efficient filtration effect.
  • Improves casting surface performance and density.
  • Prolongs the working life of the casting through improved structure.
  • High chemical stability, unaffected by melted metals.
  • Precise dimensions suitable for automated production lines.

Frequently Asked Questions
What is the primary function of a DPF?
A Diesel Particulate Filter (DPF) is designed to capture and remove particulate matter (soot) from the exhaust gas of a diesel engine to meet strict emission standards.
How does the DOC + CDPF system work together?
The DOC oxidizes carbon monoxide and hydrocarbons while converting NO to NO2. This NO2 then reacts with the carbon particles captured in the CDPF at low temperatures to produce CO2, enabling passive regeneration.
What materials are used for the filter substrate?
Common materials include Cordierite ceramics, aluminum titanate, and silicon carbide, chosen for their thermal stability and filtration efficiency.
Is the DPF renewable for long-term use?
Yes, these filters are designed to be renewable for long-term use without damage, provided proper regeneration strategies are followed.
What emission standards do these products support?
Our products are designed to support various standards including Euro III, Euro IV, Euro V, and Euro VI, as well as non-road Tier 4 requirements.
Can you provide customized sizes?
Yes, we provide a wide range of standard sizes and can also manufacture customized specifications based on specific engine emission inputs and customer needs.
