How to Clean the Three-Way Catalytic Converter in a Car?

[VanAmara]

Methods for cleaning the three-way catalytic converter in a car: Add cleaning agent to the fuel tank via an "IV drip" method. Specific steps: 1. Start the engine and wait until the water temperature is normal before turning off the engine; 2. Pour the cleaning agent 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, open the flow control valve, and slowly drip the cleaning agent into the intake manifold for about 30 minutes; 4. After cleaning, keep the engine running at the same RPM for 3 to 5 minutes to expel residual liquid. This method uses the intake vacuum suction to draw the cleaning agent into the combustion chamber. After combustion, it creates a high-temperature oxidation environment inside the three-way catalytic converter. Through redox reactions, it converts sulfur, phosphorus compounds, and unburned gasoline residues on the three-way catalytic converter into gases like carbon dioxide and sulfur dioxide, which are then expelled through the exhaust pipe. This helps restore the activity of the rare metals on the three-way catalytic converter.
