Types of catalytic converters

There are various types of catalytic converter. A simple ‘two-way’ oxidation cat works to turn carbon monoxide (CO) to carbon dioxide (CO2) and hydrocarbons, which are basically particles of unburnt fuel, to carbon dioxide and water. More advanced ‘three-way’ catalytic converters are fitted to modern cars and these do the above while also reducing emissions of nitric oxide (NO) and nitrogen dioxide (NO2) which together are more commonly known as NOx, a major cause of localised air pollution. In the type of CCO (Catalytic Converter for Oxidation), Oxygen will react with CO and HC to form CO2 and H2O which do not contain pollution. For this oxidation process to run well.

Three-Way Catalyst

Of all the types of Catalytic Converters, this one is the most ideal. In addition to CO and HC, NOx will also be converted into non-polluting substances. The NO and O2 processes will function as.

Oxidation Catalyst

This type of Catalytic Converter is a combination of an oxidation catalyst and a three-way catalyst that aims to reduce air pollution even more optimally.
