How to Use Automotive Three-Way Catalytic Converter Cleaner?
4 Answers
Automotive three-way catalytic converter cleaner adopts the method of intravenous drip cleaning. This method involves connecting a plastic hose to the engine's vacuum solenoid valve, and relying on the air pressure in the hollow tube to draw the cleaning agent from the infusion bottle into the engine. As the cleaning agent is expelled through the exhaust pipe, it cleans the three-way catalytic converter. The three-way catalytic converter is the most important external purification device installed in the automotive 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. The service life of a three-way catalytic converter ranges between 80,000 to 100,000 kilometers. The specific lifespan depends on the vehicle's usage conditions, and it is also related to the quality of fuel used and the driving environment.
With over 20 years of driving experience, I frequently use catalytic converter cleaners. My routine is to add one standard bottle when the fuel tank is at 1/4 capacity, shaking the bottle thoroughly to ensure proper mixing. Then I drive on highways maintaining engine RPM above 2000 for 30-50 kilometers, allowing the engine temperature to rise and help the cleaner dissolve carbon deposits and contaminants. After cleaning, the converter becomes cleaner, reducing exhaust emission risks while improving throttle response and fuel efficiency. Important notes: Never use during cold starts, choose reputable brands, once annually is sufficient to avoid costly repairs from clogging. Best combined with regular maintenance checks for preventive care.
I bought my car less than two years ago and find using a ternary catalytic cleaner super easy: choose a cleaner with good reviews, pour it into the fuel tank when it's about a quarter full, and shake the bottle before adding to avoid sediment. Avoid short trips when driving; it's best to plan a long-distance journey on the highway for about 40-50 kilometers, keeping the RPM high to let the cleaner work thoroughly. After removing pollutants, emissions become cleaner, and there's a slight improvement in acceleration performance. Be careful not to add too much for convenience; once every six months to a year is appropriate. If the car is often driven in traffic jams, cleaning can extend the catalytic converter's lifespan, preventing early failure. Overall, it's hassle-free and safe.
Using a three-way catalytic converter cleaner is beneficial for the environment: Add one bottle to the fuel tank when there is little fuel left according to the instructions, and drive the vehicle at high engine speeds for over 30 kilometers to raise the temperature and dissolve pollutants, thereby reducing exhaust emissions. After cleaning, the catalytic converter operates more efficiently, lowering emissions and improving air quality, while also extending the lifespan of automotive components and preventing clogging. Note that the operation should be performed when the engine is warm, and avoid frequent use to prevent system damage. Additional benefits include a slight reduction in fuel consumption and maintaining overall vehicle health.
