200 CPSI Double-Bed Three-Way Catalytic Converter - Reduces CO, HC & NOx Emissions in Vehicles

Aftermarket Three-Way Catalytic Conventers For Auto Parts

Product Description

1. Product Overview
A Three-Way Catalytic Converter (TWC), also known as a catalytic purifier, is an essential emission control device installed in a vehicle's exhaust system. It effectively reduces up to 90% of harmful pollutants emitted by the engine, ensuring compliance with global environmental regulations.

2. Key Components & Function
✔ Metal Housing – Durable stainless steel construction for corrosion resistance
✔ Honeycomb Substrate (Ceramic/Metal) – High-surface-area design (200-600 CPSI) for optimal gas contact
✔ Catalytic Layer (Washcoat) – Contains precious metals (Pt, Pd, Rh) to enable redox reactions:
• Platinum (Pt) oxidizes CO → CO₂ and HC → H₂O + CO₂
• Rhodium (Rh) reduces NOx → N₂ + O₂

3. Performance Highlights
✔ High Conversion Efficiency:
• CO & HC reduction ≥95%, NOx reduction ≥90% (at optimal temperature)
✔ Low Light-Off Temperature:
• Reactions initiate at ≥250°C (rapid cold-start performance)
✔ Durability:
• Resists thermal shock (up to 950°C)
• 100,000+ km lifespan under normal conditions
4. Critical Usage Notes
⚠ Fuel & Oil Requirements:
• Avoid leaded gasoline – Causes permanent catalyst poisoning
• Low-sulfur/phosphorus oils – Prevents washcoat contamination
⚠ Operating Temperature:
• Below 250°C, conversion efficiency drops significantly

5. Compliance & Applications
✅ Certifications: EURO 4/5/6, EPA Tier 3, China 6
✅ Vehicle Types: Gasoline engines, hybrids (not for diesel)
