All About Catalytic Converters

1. Article1: Globalrefininggroup.com All About Catalytic Converters As the number of vehicles is increasing, the level of pollution that is caused due to the toxic emissions resulting from fuel combustion is also rising in a rampant manner. This is one of the major issues that is harming the atmosphere as well as putting the health of every individual at risk globally. As a result of this, various laws are passed every now and then, in order to keep the environment “pollution free”. Many car manufacturers have also been researching through the years to improve car engines and fuel systems in order to deal with the issue. One of the most accepted devices that are used for this purpose is the catalytic converter. Catalytic converter is a piece of equipment that reduces the toxicity of emissions from the combustion engine. It was created by a French mechanical engineer living in United States: Eugene Houdry in the year 1950, a specialist in the field of refining of catalytic oil and was further enhanced by John J. Mooney and Carl D. Keith, who are known to be responsible for the production of catalytic converters for the first time in 1973. The device uses a metallic catalyst, which causes a chemical reaction with the noxious gases and converts them into compounds that are less harmful. Some of the most commonly used popular catalysts are platinum group metals: palladium, platinum and rhodium. There are mainly two types of a catalytic converters: Two-way converter: It is generally used in diesel engines in order to minimize the emissions of carbon monoxide and hydrocarbons. They were also used with spark ignition engines in the automobiles market in USA in the year 1981.A two-way catalyst converter conducts two tasks: It oxidises carbon monoxide to carbon dioxide and un-burnt hydrocarbons to carbon dioxide and water. Three-way converter: These are being used since 1981 by the vehicle emission control systems of North America as well as by many other countries on different vehicles. A three-way catalytic converter conducts three tasks simultaneously- Oxidisation of carbon monoxide to carbon dioxide, un-burnt hydrocarbons to carbon dioxide and water and reduce nitrogen oxides to nitrogen and oxygen. These reactions occur more effectively when the catalytic converter gets the exhaust gas through the engine that runs to some extent, above the stoichiometric point. In general, the engines that are fitted with three-way catalytic converters are subjected to a computerized enclosed loop response fuel injection method, which employs more than one oxygen sensor. Though, during the time of deployment of the three-way converters, carburettors that were equipped with feedback mixture managing systems were used. While a three-way catalyst was employed in a system known as open-loop system, Nitrogen monoxide reduction competence was low. Within a fine fuel/air ratio band that surrounds stoichiometry, the three pollutants are nearly converted. However, outside the band, the conversion ratedrops very rapidly. This was a general understanding and working of catalytic convertors. To know more about scrap catalytic converters prices and selling information, visit Globalrefininggroup.com ABOUT THE AUTHOR
