What is Catalytic Converter? Definition of Catalytic Converter, Catalytic Converter Meaning and Concept

A catalytic converter is a device installed in automobiles that is designed to reduce the harmful emissions released by the vehicle's exhaust.

In the United States, all vehicles produced after 1975 must have one as part of an attempt to reduce air pollution.

Car emissions consist of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxide. When these gases are not treated, they are emitted by automobiles and become the largest source of ozone at ground level. Ozone at ground level is responsible for smog, respiratory problems, and damage to plant life. A catalytic converter uses metallic catalysts, usually platinum, rhodium, or palladium, which cause a chemical reaction with harmful gases, turning them into less harmful ones.

The catalytic converter was developed in the 1960s, and by the 1970s, most vehicles were equipped with one. In 1975, the Clean Air Act in the United States required an emission reduction of 75% in all new vehicles, which was achieved with the use of the device. It is constantly being improved and is now more efficient than ever. In the United States, these improvements are consistent with the stricter Environmental Protection Agency (EPA) amendments to the Clean Air Act.

Although the catalytic converter has been very successful in reducing dangerous pollutants released by automobiles, particularly ground-level ozone, it has been criticized.

It can help solve a serious environmental problem, but its use is a trade-off at the expense of increased global warming.

The converter creates and releases gases into the atmosphere responsible for global warming.

The system increases carbon dioxide, which is released along with harmful gases from the vehicle's exhaust system.

Carbon monoxide, which is transformed into carbon dioxide, is responsible for absorbing infrared waves from the sun and causing the planet to heat up.
