Ceramic Honeycomb Substrate 150x150x300mm for Catalytic Converters | EURO 6 Compliant with 1310m²/m³ Surface Area
Modern vehicle exhaust aftertreatment systems utilize advanced technologies installed downstream of combustion engines to significantly reduce harmful emissions. These systems integrate multiple specialized components working in concert to meet stringent environmental standards.
- TWC (Three-Way Catalyst): Simultaneously reduces NOx, CO, and HC emissions in gasoline engines
- SCR (Selective Catalytic Reduction): Targets NOx reduction specifically in diesel applications
- DOC (Diesel Oxidation Catalyst): Converts CO and HC into CO₂ and H₂O
- DPF/GPF (Diesel/Gasoline Particulate Filter): Captures 99% of soot particles
- ASC (Ammonia Slip Catalyst): Prevents NH₃ leakage from SCR systems
When exhaust gases containing NOx, CO, and HC flow through the catalytic converter:
- Redox reactions occur on the catalyst surface
- Toxic compounds transform into environmentally safe outputs:
- Nitrogen oxides (NOx) → Nitrogen (N₂) + Oxygen (O₂)
- Carbon monoxide (CO) → Carbon dioxide (CO₂)
- Hydrocarbons (HC) → Water (H₂O) + CO₂
- Stricter emission standards (Euro 6d/China VI/EPA Tier 3)
- Improved catalyst formulations (Pd/Rh-based TWCs, Cu/Zeolite SCR)
- Advanced filter technologies (SiC DPFs, asymmetric-cell GPFs)
