Catalytic Converters

Catalytic Converters Information

Catalytic converters were first invented by Eugene Houdry. He was a French mechanical engineer who lived in the USA in the 1950'S.

Catalytic converters are a device that is fitted to vehicle to control its emissions. These emissions are caused as a byproduct from the burnt fuel from the vehicles engine. These emissions contain poisonous gasses. The catalytic converter lessens these gasses and substances by the way of catalyzed chemical reactions.

Many modern vehicles that run on petrol are fitted with what is known as a 'three way' catalytic converter. This is because they will convert the 3 main polluting gases from the vehicles exhaust gasses. These include the oxidizing reaction that converts the carbon monoxide and the harmful un-burnt hydrocarbons to carbon dioxide and water vapor. Also, a reduction reaction converts nitrogen oxides in to nitrogen, carbon dioxide and water.

Catalytic converters still are the most commonly used product for reducing a vehicles emissions. They are also found on mining equipment, motorbike, airplanes and even on some wood burning stoves.

Catalytic converters are made up of several components. Car catalytic converters usually have a ceramic core, this are cheap to produce and can be manufactured in large quantities. The catalyst itself is more often than not a precious metal such as platinum, palladium or rhodium. These are used as they offer the best in reduction and oxidation reactions that are key to how a catalytic converter works.
