A catalytic converter is a common exhaust emission control device, which is used to reduce harmful emissions from an internal combustion engine. This device is also referred to as a catalyst or scrubber. It helps in the conversion of harmful combustion byproducts (coppers lead, coppers and so on.) It converts toxic byproducts of combustion (coppers lead, coppers, etc.) into harmless carbon dioxide and nitrogen, oxygen, and water. The engine’s performance is enhanced through the catalytic converter which reduces harmful emissions from its fuel exhaust system.
Most vehicles come with catalytic converters that reduce harmful emissions from the engine. These harmful emissions include hydrocarbons, sulfur oxide and carbon monoxide. All these emissions affect the performance of the vehicle, and could even be harmful to the operator. 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 the gas argon is introduced into the combustion chamber to produce oxygen. The oxygen in the chamber activates the catalyst. The catalyst activated particles react with other emissions in an air stream , and become attached to them, resulting in the production of carbon dioxide or nitrogen, or water as a byproduct.
The oxidizer-based system employs catalytic converters for an oxidation system in the exhaust system. catalytic converters are designed to convert harmful exhausts from internal combustion engines into harmless substances such as nitrogen, water, and carbon dioxide. A wide range of vehicles, both heavy duty and light duty, make use of these converters to improve fuel efficiency and lower emissions. Certain heavy duty vehicles such as forklifts or mobile crane trucks, that have exhaust systems, might also require catalytic converters in order to meet emissions standards that are set by state regulatory agencies.
Catalytic converters are utilized in injection systems to stop combustion gases from entering the engine compartment. Three-way catalytic converters employ a Stoichiometric point to determine the length of time a chemical can remain active without being destroyed from external emissions. Although each three-way system is distinct however, they all adhere to the same basic principle.
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. These kits require approval from the United States Environmental Protection Agency (EPA) in order to ensure compliance with DOT emission standards.
There are many types of catalytic converters. One of the most popular kinds of automotive catalytic converters is an electrochemical catalyst washcoat that has two handles that includes a binder and an oxygen catalyst. The binder will bind any pollutants and permit them to be removed from the exhaust stream before they get to the catalytic convertor. A core cleaner is used to clean the catalyst of any remaining dust and dirt. Many of these systems include a flow control valve that shuts down the unit once it is operational. However certain systems close the unit after the washcoat has been discharged or after a predetermined time.
The final type of catalytic converter used in automobiles is the x reduction catalyst. This system employs one catalyst instead of two. Instead of allowing one kind of pollutant to enter the catalytic convertor, it breaks the polluted gases molecules into less easily combustable components. Residential applications can also use X reduction catalytic convertors. These converters come with an additional catalyst that allows for oxidation and are eco green.
