How to clean the automobile three-way catalytic converter?

1, start the engine, and turn it off after the water temperature is normal;

2. Pour this product into special equipment and connect the output connector of the equipment with the vacuum tube;

3. Start the engine, control the speed at about 2000 rpm, open the flow control valve, and slowly drip this product into the air inlet for about 30 minutes;

4. After cleaning, keep the engine speed for 3-5 minutes to discharge the residual liquid.

Regarding the cleaning of three-way catalysis, there are many kinds of cleaning agents on the market, but it is generally recognized by car owners or repair shops that oxalic acid solution is used for cleaning, and the effect is also obvious. However, this method needs to dismantle the three-way catalytic device, which has certain requirements on the conversion rate and soaking time of oxalic acid solution. Improper use will destroy the internal structure.

The second method is disassembly-free cleaning, that is, by "hanging bottles" or adding cleaning agents to the fuel tank, but this method is not as effective as the first one and is suitable for the case of slight blockage of three-way catalysis.

How often should the three-way catalytic converter be cleaned:

1, usually need to clean the three-way catalyst once every 30,000 kilometers;

2. When the waste oil and power of the vehicle are reduced, it is necessary to check the three-way catalyst and clean it as needed;

3. Every time you clean the vehicle, you need to clean the three-way catalytic converter to maintain the throttle, throttle and air intake;

4. It is best to clean the vehicle before the exhaust condition detection every year. I'm sure you want to do it once, too
