A catalytic converter is a common exhaust emission control device that is used to limit harmful emissions from an internal combustion engine. This device is also known as a catalyst or scrubber. It aids in the conversion of toxic combustion byproducts (coppers lead, coppers and lead, etc.) into harmless carbon dioxide, oxygen, nitrogen, and water. The catalytic converter helps reduce harmful emissions from the fuel exhaust system and boosts the performance of the engine.
A majority of vehicles have catalytic converters that help them meet the current standards by decreasing harmful emissions from the engine. These harmful emissions include hydrocarbons, sulfur oxide, and carbon monoxide. These emissions can have a negative effect on the vehicle’s performance and even cause harm to the operator. For example, diesel engine exhausts contain more hydrocarbons than regular engines, and diesel engines are known to generate more carbon monoxide than standard engines.
There are two types of catalytic converters that are direct air injection and an oxidizer-based system. Direct air injection is when an argon-like gas 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 carbon dioxide, nitrogen, and water as the byproduct.
The oxidizer-based system uses catalyst converters that produce oxidation in exhaust system. Catalytic converters convert dangerous exhausts from internal combustion engines to harmless substances such as water, nitrogen carbon dioxide. A variety of vehicles, both heavy duty and light duty, use these catalytic converters to increase the gas mileage and improved emissions. Catalytic converters are often required for heavy-duty vehicles such as mobile crane trucks or forklifts that have exhaust systems. This is to ensure compliance with emission standards as set by state regulatory agencies.
Catalytic converters are employed in injection systems to block combustion gases from exiting the engine compartment. Three-way catalytic converters use a stoichiometric point to determine the amount of time that a chemical will remain active , without being destroyed by the external emissions. Each three-way system differs in a small way, but all work on the same general principle.
The United States has regulations for catalytic converters. They must comply with certain emission standards. In addition, many companies sell their vehicles with federal conformity kits that contain catalytic converters. To ensure conformity with DOT emission standards, these kits have to be certified and approved by the United States Environmental Protection Agency.
There are many different types of catalytic converters. One of the most popular kinds of automotive catalytic converters is an electrochemical catalyst washcoat that has two handles which includes a binder as well as an oxygen catalyst. The binder will bind to any pollutants and allow them be eliminated from the exhaust stream prior to they can reach the catalytic converter. A core cleaner is used to clean the catalyst of any remaining dust and other debris. Many of these systems include an automatic flow control valve that shuts down the unit once it is fully functional. However certain systems close the unit after the washcoat is discharged or after a certain time.
The x reduction catalyst is the most recent type of catalytic converter that automobiles use. This type of catalyst uses one catalyst instead of two. Instead of allowing one kind of pollutant to attack the catalytic converter, it breaks the gas molecules that are polluted into smaller, more easily combustable particles. Residential applications can also make use of catalytic converters that reduce X. These converters have an additional catalyst that allows for oxidation and are eco green.
