What are the causes of catalytic damage leading to single or multiple cylinder misfires?

[BradyMarie]

Catalytic damage causing single or multiple cylinder misfires may be due to excessive carbon deposits, broken ceramic inner core, melted ceramic inner core, etc. Below is a detailed introduction about the automotive three-way catalytic converter: 1. Overview: The three-way catalytic converter is the most important external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Others: When high-temperature vehicle exhaust passes through the purification device, the purifying agents in the three-way catalytic converter enhance the activity of CO, HC, and NOx gases, promoting their oxidation-reduction chemical reactions. Since this catalytic converter can simultaneously convert the three main harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter.
