Which Cars Have a Three-Way Catalytic Converter?

[Teagan]

Nowadays, virtually all cars are equipped with a three-way catalytic converter. The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. Below is some relevant information: 1. Composition: The three-way catalytic converter is primarily composed of asbestos fiber felt, purifying agents, a carrier, and metals such as platinum, rhodium, and palladium. Among these, platinum, rhodium, and palladium are the main catalysts in the three-way catalytic converter, effectively reducing the amount of nitrogen oxides and particulate matter in the exhaust. 2. Function: 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.
