Cut Costs, Not Corners: Durable Catalytic Converters with 100,000+ Mile Lifespan
 

Product Description

 

A three-way catalytic converter (TWC) is a critical emissions control device integrated into modern vehicles to reduce toxic exhaust gases. It utilizes a combination of precious metal catalysts (platinum, palladium, and rhodium) coated on a ceramic or metallic honeycomb substrate. The TWC operates through two simultaneous chemical processes: oxidation (converting CO and HC into CO2 and H2O) and reduction (transforming NOx into N2 and O2). Designed to function optimally at high temperatures (300-900°C), it ensures compliance with stringent environmental regulations (e.g., Euro 6, EPA Tier 3) while improving air quality. Advanced TWCs feature enhanced durability, low backpressure designs, and compatibility with hybrid engines, making them indispensable for eco-conscious automotive manufacturers and aftermarket upgrades.

 

Product Parameters

Core Components & Mechanism

• Substrate Structure: A honeycomb-like ceramic (cordierite) or metallic monolith with thousands of parallel channels, maximizing surface area for catalytic reactions.

• Washcoat: A porous layer (e.g., gamma-alumina, CeO2-ZrO2 oxides) applied to the substrate, stabilizing catalyst nanoparticles and enhancing oxygen storage capacity.

• Catalyst Loading:

  • Oxidation Catalysts: Platinum (Pt) and Palladium (Pd) for CO and HC oxidation.

  • Reduction Catalyst: Rhodium (Rh) for NOx reduction.

• Oxygen Sensors Integration: Works with upstream/downstream O2 sensors to optimize air-fuel ratio (λ ≈ 1) for simultaneous oxidation and reduction.

 

It can be divided into Euro 1 (white carrier, which does not have any exhaust filtering function, but only serves as a noise reduction effect); Euro 2 (addition of rare earth compound); Euro 3 OBD (addition of platinum, palladium); Euro 4 (addition of platinum, palladium, rhodium); Euro 5 and other standards.
