Is It Necessary to Clean the Three-Way Catalytic Converter at 100,000 Kilometers?

[DeJasper]

The three-way catalytic converter typically needs to be cleaned every 30,000 kilometers. If you notice increased fuel consumption or reduced power, the three-way catalytic converter should be inspected and cleaned as needed. Additionally, it is advisable to clean the three-way catalytic converter whenever the fuel injectors, throttle body, and intake passages are serviced. Below are the symptoms of a clogged three-way catalytic converter: 1. Mild clogging stage: At this stage, chemical complexes adhere to the catalyst surface, only manifesting as reduced exhaust purification efficiency and excessive emissions. Early detection and cleaning are crucial, so regular inspections and maintenance are key. 2. Moderate clogging stage: Chemical complexes have accumulated significantly on the catalyst surface, leading to increased exhaust backpressure, higher fuel consumption, and reduced power. The engine warning light usually illuminates at this stage. 3. Severe clogging stage: Due to significant blockage, the operating temperature of the three-way catalytic converter rises. Symptoms include severe power loss, frequent stalling, and in extreme cases, a glowing red exhaust pipe, unusual noises, and foul-smelling exhaust emissions.
