1. Cleaning methods: At present, there are two main cleaning methods on the market, namely, disassembly cleaning and disassembly-free cleaning. Disassembly and cleaning requires removing the ternary catalyst and ultrasonic cleaning with professional equipment; disassembly-free cleaning is to pour the cleaning agent into the oil tank or add fuel additives, and use the high temperature generated by the idle operation of the engine to burn off the carbon and impurities on the surface of the ternary catalyst to achieve the cleaning effect.

2. Replacement method: To replace the ternary catalyst, you need to remove the old ternary catalyst and install a new ternary catalyst. It should be noted that during the replacement process, it is necessary to ensure that the new ternary catalyst is matched with the original vehicle to avoid affecting the vehicle performance and emission control effect.

Precautions

1. When cleaning or replacing the ternary catalyst, you must choose a formal repair shop or 4S store to operate to ensure construction quality and safety.

2. If the vehicle has problems such as weak acceleration and increased fuel consumption, in addition to cleaning or replacing the ternary catalyst, it is also necessary to check whether other emission control system components, such as oxygen sensors, air flow meters, etc., are working properly.

3. In daily use, it is necessary to maintain good driving habits and maintain the vehicle regularly to extend the service life of the ternary catalyst and reduce the replacement frequency.
