During car maintenance, most car owners know that the three oil filters need to be replaced regularly. If they are a little aware of car maintenance, they will also clean the throttle, air inlet and fuel injection nozzle on the car engine, which can ensure that the car can drive more quickly and save fuel. The three-way catalyst closely related to the power and fuel consumption of the engine, Many car owners often forget to maintain, so as to bring many adverse effects to the vehicle.

 

The blockage of the three-way catalyst is the most common problem causing poor engine operation. When the three-way catalyst is blocked, it will lead to poor engine exhaust, weak acceleration, stuffy and sharp increase in vehicle fuel consumption. In order to avoid the blockage of the three-way catalyst, which method should be used for cleaning at ordinary times? Now let Xiaobian explain to you what is the most effective way to clean the three-way catalyst in reality?

 

The first method: add cleaning agent to the oil tank

 

This method is very common in the market. The biggest advantage is that it is cheap and easy to operate. You only need to add this type of cleaning agent directly to the oil tank, but the cleaning effect of this product on the three-way catalyst is very small; Because this product has been burned out when it reaches the three-way catalyst after burning in the combustion chamber, there is almost no cleaning effect.

 

The second method: hanging bottle cleaning

 

Hanging bottle cleaning is also called disassembly free cleaning. At present, this method of cleaning three-way catalyst is the most popular in the market. The biggest advantage is that there is no need to disassemble the three-way catalyst. The disadvantage is that the cost of purchasing cleaning equipment is expensive and the cleaning effect is not good.

 

This kind of hanging bottle cleaning is to suck the cleaning agent into the combustion chamber through the intake vacuum suction. After combustion, a high-temperature oxidation environment is established in the three-way catalyst, and then the sulfur and phosphorus chemicals on the three-way catalyst and the unburned residual products of gasoline are transformed into carbon dioxide, sulfur dioxide and other gases and discharged out of the exhaust pipe through redox reaction, So as to restore the activity of rare metals on the three-way catalyst.

 

The third method: disassembly and cleaning

 

Disassembly and cleaning is a very laborious method. It is necessary to completely disassemble the three-way catalyst from the vehicle, soak it in cleaning agent (oxalic acid and toilet cleaning spirit) for a period of time, and then rinse it with clean water. In fact, this method of cleaning the three-way catalyst is the most effective.

 

But now many auto repair shops are very profitable. They can make money quickly by putting a hanging bottle with cleaning agent. No one is willing to disassemble the three-way catalyst for cleaning. Unless the three-way catalyst is completely blocked or broken, they will disassemble the three-way catalyst only driven by great profits.

 

Based on the above three methods of cleaning the three-way catalyst, disassembly and cleaning is undoubtedly the best cleaning effect, but due to time-consuming and laborious, the charging price is also very high. Although the method of adding cleaning agent to the oil tank and hanging bottle cleaning is simple and cheap, it is ultimately a palliative action, and the three-way catalyst will still have problems.
