three on the vehicleYuanThe catalytic converter needs to be cleaned regularly. If it is not cleaned for a long time, it is easy to be blocked or some failures occur. The exhaust emission does not meet the emission standards, and the annual inspection of the vehicle will be difficult to pass. How to clean the three-way catalytic converter of the car? ?
1. First remove the three-way catalytic converter, and then soak the three-way catalytic converter with oxalic acid, and it can be cleaned after soaking for a while. This method is the most effective method, but it requires a lot of manpower and time. Most 4S shops will not help you to remove and clean the three-way catalytic converter.
2. There is no need to remove the three-way catalytic converter, and use the method of hanging a bottle to clean it. The cleaning effect will be worse than the previous method, but the cost is still high. This is a more commonly used cleaning method in 4S stores.
3. We need to buy a special three-way catalyst cleaning agent, and put the cleaning agent in the fuel tank of the car. When the vehicle is ignited and started, the engine will enter the working state, so that the cleaning agent will pass through the position of the three-way catalytic converter, and the three-way catalytic converter will be cleaned when passing, and finally the cleaning agent will be discharged from the exhaust pipe. This method is relatively simple, we can operate it ourselves without going to the 4s store, which is very affordable.
The cleaning cycle of the three-way catalytic converter is almost the same as drivingmileageReached 30,000 kilometers for cleaning, but it still depends on the specific conditions of the vehicle. If the vehicle is very laborious when going uphill, the vehicle will consume more fuel than usual, then we may need to check the three-way catalytic converter and clean it.
