1.Add cleaning agent
A more common way is to add a cleaning agent to the fuel tank, which is simple, convenient and low cost. You only need to add the corresponding cleaning agent directly to the fuel tank. However, the cleaning effect of this method is not very good, because the cleaning agent is burned out when it reaches the three-way catalyst after burning through the combustion chamber, so the effect is not good.
2. Hanging bottle cleaning
Hanging bottle cleaning is also called no-disassembly cleaning. This method is more popular now. The 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 ideal.
The hanging bottle is cleaned by the suction of vacuum and suction. After the cleaning agent is sucked into the combustion chamber and burned, a high-temperature oxidation environment is established inside the three-way catalyst. The unburned products of gasoline and gasoline are converted into carbon dioxide, sulfur dioxide and other gases and then discharged out of the exhaust pipe, and finally the purpose of recovering the activity of rare metals on the three-way catalyst is achieved.
3. Disassembly and cleaning
Disassembly and cleaning is the most thorough cleaning method, but it is time-consuming and laborious. It is necessary to completely remove the three-way catalyst from the vehicle, and then soak it with a cleaning agent for a period of time before cleaning it with water. But this operation is by far the most effective cleaning method.
4.SH2.0 HHO Cleaning Machine
Adopting the most advanced HHO technology, independent research and development design. Hydrogen and oxygen are produced by electrolyzing water, and the carbon deposits are cleaned using the characteristics of hydrogen and oxygen to achieve good results. At the same time, SH2.0 added DPF and three-way catalytic converter cleaning function on the basis of cleaning the engine. Three items for three charges.
