catalytic Converters What is a catalytic converter and how does it do what they do. The condition Catalytic Converter covers the stainless steel box attach in the exhaust system. Inside the cover is the catalyst, a ceramic or metallic base with an active coating incorporating alumina, ceria and another(prenominal) oxides and combinations of the cunning metals platinum, palladium and rhodium. The base scum bag be protected from thrill and shock by a live ceramic or metallic mat The important by-products of combustion ar: Nitrogen gas (N2): Our airwave is 78 percent overdue north gas, and most of this passes right finished the car engine. degree centigrade Dioxide (CO2): A harmless, odorless gas composed of century and typecast O. It is also a greenhouse gas that contributes to global warming. body of water evaporation (H2O): Another by-product of combustion. The hydrogen in the force out bonds with the oxygen in the air. These three emissions are mostly harmless, alt hough coulomb dioxide emissions are believed to contribute to global warming. However since the combustion do by is never perfect, other more harmful emissions are asseverated in the process. Carbon monoxide (CO): A colorless, odorless gas. It is poisonous and extremely chanceful in captive areas, building up slowly to toxic levels without warning if fair to middling ventilation is not available. Hydro carbon copys or volatile organic compounds (VOCs): every chemical compound make up of hydrogen and carbon.
Oxides of nitrogen (NOx): Chemical compounds of nitrogen, they combine with hydrocarbons to produce smog. These are the three main regulated emissions! , and also the ones that catalytic converters are designed to reduce. Catalytic converters can either be an oxidation or three-way type. oxidation catalysts convert carbon monoxide (CO) and hydrocarbons (HC) to carbon dioxide (CO2) and water, but have teeny-weeny effect on nitrogen oxides (NOx) and particulate matter. Three-way catalysts break down in a closed-loop system together... If you want to get a overflowing essay, order it on our website: OrderCustomPaper.com
