What is the purpose of a car's three-way catalytic converter?

[StBrooklyn]

It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Below is an introduction to the three-way catalytic converter: Introduction: The three-way catalytic converter refers to the process of transforming harmful gases like CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Three-way catalytic converter: It primarily uses a three-way catalytic converter, whose core component is a porous ceramic material installed in a specially designed exhaust pipe. It is called a "carrier" because it does not participate in the catalytic reaction itself but is coated with precious metals such as platinum, rhodium, palladium, and rare earth coatings. It is the most important external purification device installed in a vehicle's exhaust system.
