How to prolong the service life of three-way catalytic converter

Abstract: Three-way catalytic purifier plays an important role in the safe emission of automobile exhaust. The three-way catalytic converter also has a life, but there is no definite time limit for the specific life, which depends on the condition of burning engine oil, and also has a certain relationship with the fuel quality and driving environment used by the car. The three-way catalytic converter is so important that we can take some measures to extend the service life of the three-way catalytic converter in daily use. Let's have a look. 1. How long is the service life of the three-way catalytic purifier?

The service life of three-way catalytic converter is determined according to the combustion engine oil. Under normal circumstances, the minimum service life of the three-way catalytic converter is about 6.5438+0.3 million kilometers. Normal means there is no blockage.

In fact, the three-way catalytic converter will be blocked for many reasons, such as high carbon deposition, poor engine oil quality, serious engine oil combustion, long-term driving on congested roads and so on. Therefore, the service life of the three-way catalyst should be judged according to the specific situation. Cleaning the three-way catalytic converter regularly is not only helpful to improve the performance of the vehicle engine, but also can reduce the frequent alarm of the oxygen sensor in the exhaust system.

Second, how to prolong the service life of three-way catalytic converter

1. It is suggested that car owners choose some regular and reputable gas stations to refuel, because the catalytic converter is very sensitive to leaded gasoline. If the refueling is not clean, it will easily lead to three-way failure and other failures, and it will also lead to the blockage of the catalytic converter.

2. It is necessary to clean the three-way catalytic converter regularly. Many car owners think it's just washing the throttle, air intake, fiddling with the nozzle, etc. If they know more, they may pay attention to spark plugs, but this will only play a palliative role. Because the position of the throttle is at the end, it is impossible to clean the throttle and other positions. It is recommended to clean the throttle and other positions together with Sanyuan, even if it is to save costs. Theoretically, it is recommended to clean every 30,000 kilometers. The owner can flexibly grasp the cleaning rhythm according to the environment and habits. For example, after cleaning up the carbon deposit, it is found that the power is still insufficient, so at this time, the three yuan can be cleaned up.

3. Prevent bottoming out and try not to bottom out in daily driving. The core components of three-way catalytic converters of most vehicles are made of ceramic technology, so they are very fragile. If serious bottoming occurs, it may cause internal injuries, so you need to pay attention to safety in daily driving.
