How to Clean a Car's Three-Way Catalytic Converter?
1 Answers
Methods for cleaning a car's three-way catalytic converter: 1. Use oxalic acid solution for cleaning, which is highly effective. However, this method requires disassembling the three-way catalytic device, and there are specific requirements for the dilution ratio of the oxalic acid solution and soaking time. Improper use may damage the internal structure. 2. Non-disassembly cleaning, which involves "drip cleaning" or adding cleaning agents to the fuel tank. This method is less effective than the first one and is suitable for mild blockages in the three-way catalytic converter. The three-way catalytic converter refers to a catalytic device that converts harmful gases such as CO, HC, and NOx emitted from car exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The core component of the three-way catalytic converter is a porous ceramic material installed in a specially designed exhaust pipe.
