How long does the three-way catalytic converter need to be cleaned?

The three-way catalytic converter of Pacific Auto Network is cleaned every 20,000 kilometers. The carrier component of the three-way catalytic converter is a porous ceramic material, which is installed in the special exhaust pipe. It is said that it does not participate in the catalytic reaction itself, and its surface is covered with a layer of precious metals such as platinum, rhodium and palladium and rare earth coatings. It is the most important external purification device installed in the automobile exhaust system.

Generally, it is cleaned once every 20,000 kilometers, and the three-way catalyst is mainly used. The carrier component of the three-way catalyst is porous ceramic material, which is installed in the special exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself, but is covered by a layer of precious metals and rare earths such as platinum, rhodium and palladium. It is the most important external purification device installed in the automobile exhaust system.

The three-way catalytic converter is cleaned every 40,000 kilometers;

1. Under normal circumstances, the three-way catalytic converter needs to be cleaned every 30,000 kilometers; When you feel that the vehicle is running out of oil and electricity, you need to test the three-way catalytic converter and clean it as needed;

2. Clean the fuel injector, throttle and air inlet during maintenance. It is best to clean the three-way catalytic converter by the way.

3. It is best to clean the three-way catalytic converter before the annual inspection last year to ensure that the vehicle passes the exhaust gas inspection smoothly. Three-way catalytic converter is very easy to block because of its honeycomb structure. Due to the poor quality of fuel in China, the use of manganese-containing antiknock agent in fuel, sulfur-containing antioxidant in lubricating oil and road congestion, the three-way catalytic converter is prone to poisoning failure and blockage.
