How Do Three-way Catalytic Converters Work?

• A three-way catalytic converter has three simultaneous tasks:
• 1. Reduction of nitrogen oxides to nitrogen and oxygen: 2NOx → xO2 + N2
• 2. Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2
• 3. Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + [(3x+1)/2]O2 → xCO2 + (x+1)H2O

Reasons for Converter Failure

• OVERHEATED / MELTED: Often caused by unburned fuel entering the converter from a faulty: Spark Plug, Exhaust Valve, Oxygen Sensor, Fuel Injector
• CATALYST POISONING: Often caused by exposure to emissions substances from: Leaky Cylinder Head Gasket, Silicone-Based Sealant, Improper Fuel (E85, Diesel), Worn Piston Ring / Valve Seal
• STRUCTURAL DAMAGE: Often caused by road debris, corrosion or other conditions such as: Air Gap Pipe Failure, Flex Pipe Failure, Stripped O2 Sensor Threads, Broken Hangers

Material Selection and Manufacturing Process

• Sturdy and Durable: All T409 stainless steel raw materials are rigorously tested to work at high temperatures as well as to effectively prevent rusting.
• High Flow Cat: Fully filling the honeycomb and covering more metal Pt/Pd/Rh per unit area can effectively improve the conversion rate.
• Direct-Fit: Fully automated manufacturing, machine cutting, machine bending, machine welding etc. effectively reducing human error, ensuring compatibility and quality at the same time.
• Breathe Freely and Healthily: Engineered to meet your vehicle’s specific emissions requirements, never worry about P0420 or P0430 code and keep check engine light off.
