catalyst

The catalytic converter is a key component of the exhaust system in modern vehicles and ensures that harmful exhaust gases are reduced. It converts pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and unburned hydrocarbons (HC) into less harmful substances such as carbon dioxide, nitrogen, and water.

Inside the catalyst is a ceramic or metallic honeycomb structure with a large surface area. This structure is coated with precious metals such as platinum, palladium, or rhodium, which act as catalysts for the chemical reactions. As the hot exhaust gases flow through the catalyst, the pollutants are transformed by these reactions.

The catalytic converter works closely with other components of the exhaust system, especially the lambda sensor. The lambda sensor measures the oxygen content in the exhaust gas and enables the engine control unit to precisely regulate the air-fuel mixture so that the catalytic converter can function optimally.

A damaged or clogged catalytic converter can lead to a loss of power, increased fuel consumption, or the activation of the engine warning light. Furthermore, emissions levels can rise, which can cause problems during vehicle inspections.
