Does the Three-Way Catalytic Converter Need Cleaning?
1 Answers
The three-way catalytic converter does need cleaning. Due to high sulfur content in fuel, poor fuel quality, or stop-and-go traffic conditions where fuel does not burn completely, leading to excessive emissions, a large amount of chemical deposits can accumulate on the three-way catalytic converter after a period of driving. The three-way catalytic converter is an important external purification device installed in the vehicle's exhaust system, which converts harmful gases such as CO, HC, and NOx in vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. Theoretically, it is recommended to clean it every 10,000 kilometers, but the cleaning frequency can be adjusted flexibly based on the driving environment and habits. If power deficiency persists after cleaning carbon deposits, the three-way catalytic converter can be cleaned.
