How much does it cost to wash three-way catalyst, and the price of one-time cleaning of three-way catalyst

threeYuanThe catalytic converter filters the harmful gases such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) in the exhaust gas, and converts them into non-toxic and harmless water (H₂O), carbon dioxide (CO2), and nitrogen. (N2) and oxygen (O2). No matter how brave the steed is, there will be a day of fall. If you want to use it longer, you must take care of it. So how much does it cost to wash the three-way catalytic converter once?

How much does the three-way catalytic cleaning cost?

The price of cleaning three-way catalytic converters on the market varies greatly, and is probably in the price range of 200-1000 yuan. At present, there are three types of three-way catalytic cleaning: additive cleaning, bottle cleaning and disassembly cleaning.The most mainstream, but also 4S shops and repair shops, is the bottle cleaning. Bottle cleaning has a relatively good cleaning effect, and at the same time it is easy to operate and easy to use.

Explore three cleaning methods

①Additive cleaning:Additive cleaning is to add cleaning agent to the fuel tank. After the vehicle is started, the cleaning agent will enter the combustion chamber along with the gasoline to burn and finally be discharged in the exhaust pipe. Catalyze for cleaning. This method is affordable and easy to operate, but the effect is worrying.

② Disassembly and cleaning:Disassembly and cleaning need to completely disassemble the three-way catalyst and soak and clean with oxalic acid. This method has the best cleaning effect, but the operation is troublesome, time-consuming and laborious, and many 4S shops and repair shops are unwilling to provide disassembly and washing services.

③ Bottle cleaning:The three-way catalyst is cleaned by slinging, which is currently the most mainstream cleaning method, and it is also a cleaning project strongly promoted by 4S shops and repair shops. This method does not need to disassemble the three-way catalyst and is easy to operate; the disadvantage is that the material cost is relatively expensive, and the cleaning effect is better than the former, but compared to the material cost, the cleaning effect is not ideal.
