In modern vehicles, three-way catalysts are a crucial90sarcadeIts main function is to reduce harmful gases such as carbon monoxide, nitrogen oxides and hydrocarbons in engine emissions into less harmful carbon dioxide, nitrogen and water vapor. However, over time and different usage conditions, the three-way catalyst may become clogged, which not only affects the performance of the vehicle, but may also lead to excessive emissions. This article will introduce in detail the causes and solutions of three-way catalytic converter clogging.

Causes of clogging of three-way catalytic converter:

190sarcade. Poor fuel quality: Using fuels high in lead or sulfur can damage the activity of the catalyst and lead to clogging.

2. Incomplete engine combustion: If the engine burns incompletely, unburned oil will enter the catalyst, deposit and eventually block.

3. Oil pollution: Additives and impurities in the oil may also enter the catalyst through combustion, causing clogging.

4. Long-term low-speed driving or frequent short-distance driving: This will cause the catalyst to be too hot to effectively burn deposits.

Methods to solve the blockage of three-way catalytic converter:

1. Use high-quality fuels: Ensure that clean fuels that meet standards are used to reduce the deposition of harmful substances.

2. Regular engine maintenance: including replacing air filters, spark plugs and oil to ensure engine combustion efficiency.

3. Avoid long-term low-speed driving: Moderate high-speed driving can help the catalytic converter reach its operating temperature and remove some deposits.

4. Use catalyst cleaners: There are special catalyst cleaners on the market that can be used regularly to help remove deposits.

5. Inspection and replacement of the catalyst: If none of the above methods can solve the problem, it may be necessary to check the actual condition of the catalyst and replace it if necessary.

Through the above method, the problem of clogging of the three-way catalyst can be effectively solved and the emission performance and power performance of the vehicle can be restored. Car owners should choose appropriate solution strategies based on actual conditions and carry out regular vehicle maintenance to extend the service life of the catalytic converter.
