Catalytic converters are popular exhaust emission control devices that help reduce harmful emissions from internal combustion engines. This device is also referred to as a catalyst, or a scrubber. It aids in the conversion of toxic combustion products (coppers, lead etc. into harmless carbon dioxide, nitrogen, oxygen and water. The engine’s performance is improved through the catalytic converter which reduces harmful emissions from the fuel exhaust system.
Majority of vehicles come with catalytic converters to help them meet the current standards by reducing 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 can even be harmful to the person driving it. For example the exhausts of diesel engines contain more hydrocarbons than regular engines, and diesel engines generally generate more carbon monoxide than regular engines.
There are two kinds of catalytic converters that are direct air injection and an oxygenizer-based system. Direct air injection is where gases like argon are injected directly into the combustion chamber to create oxygen. The oxygen in the chamber triggers the catalyst. The catalyst activated particles mingle with other pollutants in the air stream and adhere to them, leading to the production of carbon dioxide, nitrogen, and water as the byproduct.
The oxidizer-based system uses catalyst converters to produce an oxidation reaction 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 wide range of vehicles, both light and heavy, to increase gas mileage and reduce emissions. Catalytic converters might be required for heavy-duty vehicles , such as mobile crane trucks and forklifts equipped with exhaust systems. This is to ensure that the vehicle is in compliance with emission standards set forth by state regulatory agencies.
Injection systems also utilize catalytic converters to ensure that the gases from combustion do not escape from the engine compartment. Three-way catalytic converters use a Stoichiometric point to determine how long a chemical will remain active and not be destroyed by emissions from outside. Each three-way converter will differ slightly, however, they all work according to the same basic principle.
The United States has regulations for catalytic converters. They must comply with certain emission standards. Additionally, many manufacturers sell their vehicles with federal conformity kits that include catalytic converters. To ensure conformity to DOT emissions standards, these kits must be certified and approved by the United States Environmental Protection Agency.
There are many kinds of catalytic converters. One of the most popular kinds of automotive catalytic converters is an electrochemical catalyst washcoat with two handles which includes a binder as well as an oxygen catalyst. The binder will bind to any pollutants and let them be removed from the emissions stream before they reach the catalytic converter. An electrochemical catalyst washcoat typically comes with a rinsecoat which eliminates small particles, and an aqueous cleaner that removes the catalyst of any remaining dust and debris. Many of these systems include a flow control valve that shuts off the unit when it is functional. However, some systems will shut down the unit once the washcoat has been emptied or after a set time.
The last type of catalytic converter used in automobiles is the x reduction catalyst. This type of converter uses only one catalyst instead two. Instead of letting a single kind of pollutant to attack the catalytic convertor, it splits the polluted gases molecules into less easily combustable parts. Residential applications can also use catalytic converters that reduce X. These converters come with separate catalysts that allow for oxidation and are eco green.
