How to Clean the Three-Way Catalytic Converter of a Sedan?
1 Answers
The cleaning methods for the three-way catalytic converter of a sedan are: 1. Use oxalic acid solution for cleaning, which has a very noticeable effect. However, this method requires disassembling the three-way catalytic converter, and there are certain requirements for the mixing ratio of the oxalic acid solution and the soaking time. Improper use may damage the internal structure. 2. No-disassembly cleaning, which involves using an IV drip or adding a cleaning agent to the fuel tank, but this method is not as effective as the first one and is suitable for minor blockages of the three-way catalytic converter. The three-way catalytic converter has a usage cycle, and the length of its service life is closely related to the quality of the fuel. If the fuel quality is poor and combustion is incomplete, many compounds will adhere to the surface of the three-way catalytic converter. Over time, this can cause the three-way catalytic converter to become poisoned and lose its purification function.
