Catalytic converters are common exhaust emission control devices that can reduce harmful emissions from internal combustion engines. This device is also known as a catalyst or scrubber. It aids in the conversion of harmful combustion products (coppers, lead etc. into harmless carbon dioxide, nitrogen, oxygen and water. The catalytic converter decreases harmful emissions from the fuel exhaust system and improves the performance of the engine.
Most cars have catalytic converters , which help to reduce 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 can even cause harm to the user. Diesel engines emit more carbon monoxide than other engines.
There are two types of catalytic converters: direct air injection and an oxygenizer-based system. In direct air injection, the gas argon is in the combustion chamber to create oxygen. The oxygen in the chamber activates the catalyst. The catalyst activated particles react with other emission in an air stream , and connect to them, resulting in the production carbon dioxide, nitrogen, or water as an byproduct.
The oxidizer-based system uses catalytic converters to provide oxidation in the exhaust system. Catalytic converters convert dangerous exhausts from internal combustion engines to harmless substances such as water, nitrogen carbon dioxide. They can be utilized by a wide range of vehicles, both light and heavy, to improve gas mileage and reduce emissions. Some heavy duty vehicles, like forklifts and mobile crane trucks, that have exhaust systems, might also require catalytic converters in order to comply with emission standards set by state regulatory agencies.
Catalytic converters are employed in injection systems to stop combustion gases from escaping the engine compartment. Three-way catalytic convertors use 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 general principles.
The United States has regulations for catalytic converters. They must meet certain emission standards. Additionally, many manufacturers offer their vehicles with federal conformity kits that include catalytic converters. These kits must be approved by the United States Environmental Protection Agency (EPA) in order to ensure compliance with DOT emission standards.
There are many kinds of catalytic converters. One of the most sought-after types of catalytic converters for cars is a two-handle electrochemical catalyst washcoat which includes a binder as well as an oxygen catalyst. The binder will bind any pollutants and permit them to be removed from the exhaust stream prior to they can reach the catalytic converter. A core cleaner is employed to clean the catalyst of any remaining dust and debris. Most of these systems have a flow control valve that can shut down the unit once it is fully functional; however there are a few systems that will shut off the unit upon discharge of the washcoat or after a predetermined period of time.
The final type of catalytic converter found in automobiles is the x reduction catalyst. This system uses a single catalyst instead of two. Instead of allowing one kind of pollutant to enter the catalytic converter, it splits the polluted gases molecules into more easily combusted parts. Residential applications can also make use of X reduction catalytic convertors. These converters come with separate catalysts that allow for oxidation and are eco sustainable.
