The economical reasons limited resources of platinum group noble metal and some operating limitations of platinum group metal based catalytic converters. A catalytic converter is a device used to reduce the emissions from an internal combustion engine automobiles and vehicles.

Thus toxic by-products are produced.

Catalytic converter in automobiles is used to control. A catalytic converter which is placed inside the tailpipe due to which deadly exhaust gases containing un-burnt Hydrocarbon CO gas etc. Enough oxygen is not available to oxidize the carbon fuel in these engines completely into carbon dioxide and water. When the exhaust passes through catalytic convertor unburnt hydrocarbons get converted into carbon dioxide and water carbon monoxide is converted to carbon dioxide and nitric oxide is converted to nitrogen gas.

Out of these two types the three-way catalytic converters are now commonly used in automobiles. In the catalytic converter there are two different types of catalyst at work a reduction catalyst and an oxidation catalystBoth types consist of a ceramic structure coated with a metal catalyst usually platinum rhodium andor palladiumThe idea is to create a structure that exposes the maximum surface area of catalyst to the exhaust stream while also minimizing the amount of catalyst. The first engine exhaust gas treatment devices were introduced in 1975.

Cholakov Encyclopedia of Life Support Systems EOLSS The need to control engine emissions was recognized as early as 1909. There are different types of catalysts used in the automobile vehicles exhaust gas emissions controls like noble metal. Catalytic convertors consist of expensive metals like platinum- palladium and rhodium as catalysts which are fitted in the automobiles to reduce the emission of poisonous gases.

A catalytic converter is a device used to reduce the emissions from an internal combustion engine used in most modern day automobiles and vehicles. A catalytic converter is an emissions control device that converts toxic gases and pollutants in exhaust gas to less toxic pollutants. The use of TWCs in conjunction with an oxygen sensor-based closed-loop fuel delivery system allows for simultaneous conversion of the three criteria.

Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide. Many types of catalysts have been investigated for CO oxidation purposes ie noble metal base metal rare earth. The event handler performs the vehicle lookup in the database.

The only control on the page is a TextBox control for entering the VIN. You define an event handler for the change event of the TextBox control. To control this automobile exhaust pollution the catalytic converters are used.

As a point of reference the. It has an additional ability to reduce the NOx emission if compared to the two-way catalytic converters. A catalytic converter is an emissions control device that converts more toxic exhaust gas pollutants into less toxic pollutants.

Environmental ecological and health concern result in increasingly stringent emissions regulations of pollutant emissions from vehicle engines. POLLUTION CONTROL TECHNOLOGIES Vol. III - Catalytic Converters and Other Emission Control Devices - G.

Among all the types of technologies developed so far use of catalytic converters is the best way to control auto exhaust emission. The catalytic converter was invented by Eugene Houdry a French mechanical engineer and expert in catalytic oil refining. Catalytic Converters - Three-Way Catalytic Converter.

The page provides manufacturing information on the identified vehicle and that information is used in rating the vehicle for insurance. Catalytic converters have been used in vehicle emissions control for many years eg three-way catalytic TWC converters in spark-ignition engines during the past several decades and DOCs in diesel engines since the 1990s. The three-way converter TWC has been the primary emission control technology on light-duty gasoline vehicles since the early 1980s.

The substrate of the DOC is usually ceramic or metallic mesh and its washcoat contains a catalyst PdPt combination. The function of the catalytic converter is to convert these gases into CO 2 water N 2 and O 2 gas and currently it is enforced for all autos. A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction an oxidation and a reduction reaction.
