How to Clean the Three-Way Catalytic Converter?
1 Answers
Methods for cleaning the three-way catalytic converter: 1. Use oxalic acid solution for cleaning, which is also very effective. However, this method requires disassembling the three-way catalytic device, and there are certain requirements for the mixing 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, but this method is not as effective as the first one and is suitable for minor blockages in the three-way catalytic converter. Below are the specific steps for "drip cleaning": 1. Start the engine and turn it off after the water temperature normalizes; 2. Pour the cleaning agent into a dedicated device and connect the device's output to the vacuum tube; 3. Start the engine, maintain the RPM at around 2000, open the flow control valve, and slowly drip the cleaning agent into the intake tract for about 30 minutes; 4. After cleaning, keep the engine running at the same RPM for 3-5 minutes to expel any residual liquid.
