Can the Three-Way Catalytic Converter Be Washed with Water?

[AmyRose]

Yes, the three-way catalytic converter can be washed with water. The cleaning method is as follows: 1. Start the engine and turn it off after the water temperature normalizes; 2. Pour the cleaning solution into a specialized device, and connect the device's output connector to the vacuum tube; 3. Start the engine, maintain the RPM at around 2000 rpm, open the flow control valve, and slowly drip the cleaning solution into the intake manifold; 4. After cleaning, keep the engine running for 3 to 5 minutes. The three-way catalytic converter is an external purification device installed in the vehicle's exhaust system. It converts harmful carbon monoxide, hydrocarbons, and nitrogen oxides from vehicle emissions into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.
