The three-way catalytic converter in a car is a cylindrical canister made of double-layer stainless steel sheets, installed in a specially designed exhaust pipe. Below is detailed information about the three-way catalytic converter: Structure of the Three-Way Catalytic Converter: The double-layer sheet sandwich contains insulating material and asbestos fiber felt, with a catalyst housed between mesh partitions inside. The catalyst contains three precious metals: platinum, rhodium, and palladium, hence the name "three-way catalytic converter." Working Principle of the Three-Way Catalytic Converter: It oxidizes and reduces the main pollutants in car exhaust—carbon monoxide, hydrocarbons, and nitrogen oxides—converting them into harmless carbon dioxide, nitrogen, and water, thereby achieving purification.
