These catalysts promote the conversion of toxic gases, such as carbon monoxide (CO), nitrogen oxides (NOx), and unburned hydrocarbons (HC), into less harmful substances.

Carbon monoxide is converted into carbon dioxide (CO2), nitrogen oxides are reduced to nitrogen (N2), and unburned hydrocarbons are oxidized into carbon dioxide and water vapor.

How Does a Catalytic Converter Work?

The functioning of a catalytic converter relies on two main processes: reduction and oxidation. These processes occur within the converter’s honeycomb-like structure, which is coated with the catalysts. As exhaust gases pass through the converter, the catalysts facilitate the desired chemical reactions.

During the reduction process, the catalysts enable the conversion of nitrogen oxides into nitrogen and oxygen.

This reaction occurs when the nitrogen oxides come into contact with the catalysts and react with carbon monoxide. As a result, the nitrogen oxides are broken down into nitrogen and oxygen, both of which are harmless gases.

On the other hand, the oxidation process involves the conversion of carbon monoxide and unburned hydrocarbons into carbon dioxide and water vapor.

This reaction occurs when the carbon monoxide and unburned hydrocarbons come into contact with the catalysts and react with oxygen in the exhaust gases. The catalysts facilitate the oxidation of these harmful gases, transforming them into less harmful substances.

The Importance of a Catalytic Converter in the 2010 Honda CRV

The catalytic converter plays a vital role in ensuring that the 2010 Honda CRV complies with emission regulations and standards.
