Product Description

DPF Introduction

DPF Introduction

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

DOC Introduction

DOC Introduction

DOC is a critical catalyst for diesel engine reprocessing. Its main function is to oxidize unburned hydrocarbons (HC) and carbon monoxide (CO) into harmless water and carbon dioxide. It also converts NO into NO2 for passive regeneration of downstream CDPF and improves SCR conversion efficiency.

Working Principle of DOC + CDPF

Working Principle
Reaction 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 emissions.
  • Continuous Utilization: NO produced is re-oxidized to NO2 to continue reacting with carbon particles.

Product Advantages

  • Excellent thermal shock resistance.
  • Unique cellular designs reduce vortex and bubbles in the casing.
  • Accurate extrusion die for stable and consistent quality.
  • Obvious filter effect and improved density of the casting.
  • Good chemical stability, unaffected by melted metal.
  • Precise dimension for automatic filter mounting production lines.

Frequently Asked Questions (FAQ)

Q1: What is the main function of a DPF? A: The 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.
Q2: How does a DOC differ from a DPF? A: A Diesel Oxidation Catalyst (DOC) focuses on oxidizing CO and HC into harmless substances and converting NO to NO2, while a DPF physically traps solid particles.
Q3: What materials are used for the catalytic converter body? A: The most common material used is Cordierite, known for its excellent thermal shock resistance and durability in high-temperature environments.
Q4: Are these converters suitable for all car brands? A: Yes, our catalytic converters are designed for universal compatibility and can be customized to fit various car brands and engine types.
Q5: What emission standards do your products meet? A: Our products are engineered to meet various international standards, including Euro 4, Euro 5, and the latest Euro 6 regulations.
Q6: Is it possible to customize the size of the honeycomb ceramic? A: Absolutely. We offer precise extrusion dies that allow for customized sizes and shapes (Round, Square, Oval) according to specific customer requirements.
