About catalytic converters

Catalytic converters are common exhaust emission control devices that reduce harmful emissions from internal combustion engines. The device could also be described as a scrubber or catalyst. It assists in the conversion of toxic combustion products (coppers, lead etc. into harmless carbon dioxide, oxygen, nitrogen, and water. The catalytic converter helps reduce harmful emissions from the fuel exhaust system and enhances the performance of the engine.

Most cars have catalytic converters which reduce harmful emissions from the engine. These emissions are mainly sulfur oxide, hydrocarbons, carbon monoxide and particulates. These emissions can have a negative effect on the performance of the vehicle, and can even cause harm to the user. Diesel engines emit more carbon monoxide than the other engines.

Catalytic converters are typically available in two forms: direct air injection or an oxidizer based air injection system. Direct air injection is when a gas such argon is injected directly into the combustion chamber to create oxygen. The oxygen in the chamber triggers the catalyst. The catalyst activated particles mix with other emissions in the air stream and attach to them, leading to the production of nitrogen, carbon dioxide, and water as an byproduct.

The oxidizer-based system uses catalyst converters to produce an oxidation process in the exhaust system. Catalytic converters convert dangerous exhausts from internal combustion engines to harmless substances like water, nitrogen, or carbon dioxide. These converters can be utilized by a range of vehicles, both light and heavy, in order to increase gas mileage and reduce emissions. Catalytic converters are often required for heavy-duty cars such as mobile crane trucks or forklifts with exhaust systems. This is to ensure compliance with the emission standards established by state regulatory agencies.

Injection systems also utilize catalytic converters to ensure that the gases from combustion are not released from the engine compartment. Three-way catalytic converters use a stoichiometric point to determine the amount of time a particular chemical will remain active , without being destroyed by emissions from outside. Each three-way converter will differ in a small way, but all work in the same way.

The United States has regulations for catalytic converters. They must meet certain emission standards. Many manufacturers also sell vehicles with federal conformity kits, which include catalytic converters. To ensure compliance with DOT emission standards, these kits have to be approved and certified by the United States Environmental Protection Agency.

There are a variety of catalytic converters. One of the most popular types of automotive catalytic converters is an electrochemical catalyst washcoat that has two handles that incorporates a binder and an oxygen catalyst. The binder will bind to any contaminants and allow them to be removed from the exhaust before they reach the catalytic convertor. A core cleaner is employed to clean the catalyst of any remaining dust and other debris. A majority of these systems have a flow control valve that closes the unit when it is functional. However certain systems shut down the unit once the washcoat has been emptied or after a set time.

The x reduction catalyst is the final type of catalytic converter automobiles employ. This system uses one catalyst instead of two. Instead of allowing one kind of pollutant to harm the catalytic converter, it divides the gas molecules polluted by the pollutant into smaller, more easily combustable particles. Residential applications may also benefit from X reduction catalytic convertors. These converters are equipped with separate catalysts that allow for oxidation, and are environmentally friendly.
