How to Solve the Problem of Clogged Three-Way Catalytic Converter?
2 Answers
Solutions for clogged three-way catalytic converter: 1. Cleaning: During vehicle operation, exhaust gases from combustion can clog the three-way catalytic converter. Excessive clogging by impurities can reduce the converter's efficiency. Cleaning the converter to remove the clogged materials can restore its normal function. 2. Replacement: If cleaning does not restore normal function, replacement is necessary. The three-way catalytic converter is a device that converts harmful gases such as CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The core component of the three-way catalytic converter is a porous ceramic material installed in a specially designed exhaust pipe. The ceramic material itself does not participate in the catalytic reaction but is coated with precious metals such as platinum, rhodium, palladium, and rare earth coatings.
I remember last time when my catalytic converter got clogged, the car felt particularly sluggish, with no power when stepping on the gas pedal, accompanied by a whining noise from the engine. That day on the highway, I tried coasting in neutral and then revving the engine, hoping the hot exhaust would flush out the blockage, but the symptoms didn't improve. It got worse over time, leading to a sharp increase in fuel consumption. Eventually, I had to tow it to the repair shop, where the mechanic fixed it with professional cleaning fluid. Otherwise, it could have caused more problems like excessive emissions or engine damage. My advice is: if you encounter similar issues, don't tough it out. After trying simple fixes yourself, go to a professional mechanic immediately. Delaying will only make repairs more expensive. For prevention, regular oil changes and using high-quality gasoline can reduce the risk of clogging.
