Good introduction:


Universal catalytic converters are designed to meet emissions requirements on a wide variety of applications. These high quality catalytic converters feature stainless steel outer shell construction for maximum durability. The internal substrate material and precious metal loading have been carefully engineered for maximum efficiency. Universal catalytic converters require welding and/or fabrication and should be installed by qualified technicians. 
  • Stainless Steel Construction
  • Available for a wide variety of applications
  • Excellent flow characteristics

A three-way catalytic converter has three simultaneous tasks.

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

These three reactions occur most efficiently when the catalytic converter receives exhaust from an engine running slightly above the stoichiometric point. Three-way catalysts are effective when the engine is operated within a narrow band of air-fuel ratios near stoichiometry, such that the exhaust gas oscillates between rich (excess fuel) and lean (excess oxygen) conditions. Three-way catalytic converters can store oxygen from the exhaust gas stream, usually when the air-fuel ratio goes lean.

Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives, and motorcycles. They are also used on some wood stoves to control emissions. This is usually in response to government regulation, either through direct environmental regulation or through health and safety regulations.


Catalytic converters require a temperature of 800 degrees Fahrenheit (426 °C) to efficiently convert harmful exhaust gases into inert gases, such as carbon dioxide and water vapor. Therefore, they are placed as close to the engine as possible.
