What is the method for cleaning a three-way catalytic converter?

[SanVivienne]

Cleaning a three-way catalytic converter involves the following steps: 1. Start the engine and let it run until the water temperature is normal, then turn off the engine; 2. Pour the cleaning solution into a specialized device, and connect the device's output connector to the vacuum tube; 3. Start the engine again, maintaining the speed at around 2000 rpm, then open the flow control valve to slowly drip the cleaning solution into the intake manifold; 4. After cleaning, keep the engine running for 3 to 5 minutes. The reasons for cleaning a three-way catalytic converter are: 1. Sulfur and phosphorus in gasoline form chemical complexes on the surface of the converter; 2. Heavy urban traffic with frequent stops and starts leads to incomplete fuel combustion, which deposits on the converter's surface; 3. Carbon deposits and particles from cleaning the fuel injectors, throttle body, or intake manifold can contaminate the three-way catalytic converter.
