Replacement Catalytic Converter



Replacement catalytic converter is a device mandated by governments internationally. How strict vs. liberal the replacement catalyic converter models are varies by the country and state. The replacement catalytic converter is the device which manages the toxic emissions of an internal combustion engine, hence the strong political connection.

Replacement catalytic converter units create a chemical reaction using the byproducts of the internal combustion engine to create other byproducts, significantly less toxic than the original byproducts. There are 3 general types of reactions controlled by a replacement catalytic converter - reactions involving nitrogen oxide, reactions involving carbon monoxide, and reation involving hydrocarbons. A replacement catalytic converter turns each of these into nitrogen and oxygen, carbon dioxide, and water, respectively. Some replacement catalytic converter units can store oxygen. This is helpful if the engine is running lean. If that's the case, the replacement catalytic converter has oxygen stored to fix the lean oil to air ratio.
