Is it necessary to clean the three-way catalytic converter?
1 Answers
The three-way catalytic converter needs cleaning. Here are the relevant details: 1. As a crucial component for vehicle exhaust treatment, the three-way catalytic converter significantly reduces pollutants in the exhaust gases. Since all exhaust gases must pass through it, it plays a vital role. If the catalytic converter is damaged or clogged, it's akin to blocking the car's exhaust pipe—resulting in noticeable power loss, increased fuel consumption, and severe exhaust pollution. 2. The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases like CO, HC, and NOx from the exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 3. When high-temperature exhaust gases pass through the purification device, the catalyst in the three-way catalytic converter enhances the activity of CO, HC, and NOx, promoting specific oxidation-reduction chemical reactions. CO oxidizes into colorless, non-toxic carbon dioxide gas at high temperatures; HC compounds oxidize into water (H2O) and carbon dioxide; and NOx reduces into nitrogen and oxygen. These three harmful gases are thus transformed into harmless substances, purifying the vehicle's exhaust. 4. The three-way catalytic converter, installed as the most critical external purification device in the exhaust system, converts harmful gases emitted from the vehicle—such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx)—into harmless carbon dioxide, water, and nitrogen via oxidation and reduction processes.
