How can the catalytic converter burn out?

[ColtonDella]

The catalytic converter does not burn out. Here is the detailed analysis: Own failure: 1. If the catalytic converter is severely burned, it will lead to a decrease in power. Poor exhaust flow can easily cause a phenomenon called sintering. Severe sintering inside the catalytic converter can lead to blockage, but it cannot burn out completely. 2. It might be that during some repair at the workshop, due to the catalytic converter being blocked, it appeared as if the catalytic converter had burned out. 3. Using poor-quality fuel, having an overly rich air-fuel mixture, or poor engine ignition can cause the catalytic converter to break easily, leading to abnormal noises.
