The most correct way to clean the three-way catalytic converter, cleaning the three-way catalytic converter video

In gasoline cars, threeYuanAs the most important component in the exhaust gas purification system, catalysis is responsible for the catalytic reduction of harmful gases such as nitric oxide (CO), hydrocarbons (HC) and nitrogen oxides NOx in the exhaust gas: the three components of CO, HC and NOx The main harmful gases are catalytically reduced into non-toxic and harmless water (H₂O), carbon dioxide (CO₂), nitrogen (N₂) And oxygen (O₂)discharge.

In the long-term use process, carbon deposits and other substances may slowly adhere to the surface of the three-way catalyzed porous ceramic, and clogging is likely to occur in the long run. Then we will introduce to you how to clean the three-way catalyst yourself.

Slinging is currently the most mainstream, and it is also a cleaning method strongly promoted by 4S shops and repair shops. In this way, a hose is connected to the engine vacuum tube, and the cleaning agent in the bottle is sucked into the engine by the negative pressure in the hollow tube, and the three-way catalyst is cleaned when it is discharged with the exhaust pipe.

Precautions:

1,If the engine stalls during cleaning, immediately disconnect the hose connecting the engine and the equipment and close the flow valve. The engine can be restarted and the idling speed is stable before reconnecting and adjusting.

2,Check whether the mixed gas concentration is appropriate to ensure that the liquid can be sucked into the air inlet in a mist.

3,The cleaning of the three-way catalyst should be carried out after cleaning the throttle gas, fuel injection nozzle and combustion chamber.

4,In the process of cleaning the three-way catalyst, the idle speed should not be too high to avoid overheating.

5,Do not drip the cleaning liquid on the painted surface of the vehicle.

6,The site for cleaning the three-way catalysis should be far away from the fire source, and fire fighting should be done well.
