As the exhaust gases pass through the converter, these metals act as catalysts, facilitating chemical reactions that transform harmful gases into less harmful ones.
The Purpose of a Catalytic Converter
The primary purpose of the catalytic converter is to reduce three main pollutants: carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC).
Carbon monoxide is a colorless and odorless gas that is highly toxic. Nitrogen oxides contribute to smog formation and respiratory issues. Hydrocarbons are unburned fuel molecules that can also contribute to smog and have adverse health effects.
The Role of the Oxygen Sensor
In order for the catalytic converter to function optimally, it relies on the feedback from the oxygen sensor. The oxygen sensor measures the amount of oxygen in the exhaust gases and sends this information to the engine control unit (ECU).
Based on this feedback, the ECU adjusts the air-fuel mixture to ensure efficient combustion and proper functioning of the catalytic converter.
