How to clean the three-way catalytic converter?

Cleaning of three-way catalytic converter: the three-way catalytic converter is cleaned by hanging bottles. This method is to connect a plastic hose to the solenoid valve of the engine, suck the cleaning agent in the infusion bottle into the engine through the air pressure in the hollow tube, and clean the three-way catalytic converter when the cleaning agent is discharged from the exhaust pipe. Composition of three-way catalyst: Three-way catalyst generally consists of shell, damping layer, carrier and catalyst coating. Shell: stainless steel material, in order to prevent scale from falling off, thus causing carrier blockage. Damping layer: composed of gasket or steel wire mesh gasket, it plays the role of sealing, heat preservation and fixing the carrier. In order to prevent the carrier from being damaged by vibration, thermal deformation and other factors, the gasket is composed of expanded mica and aluminum silicate fiber, and finally bonded with adhesive. Carrier: made of honeycomb ceramic materials, many of which are made of metal (including stainless steel). Catalyst: composed of precious metals such as platinum, rhodium and palladium, sprayed on the carrier to form a purifying agent. Service life of three-way catalytic converter: The service life of three-way catalytic converter is generally 8-65438+ 10,000 kilometers. The specific service life of a car depends on the purpose of the car, and it is also related to the fuel quality and driving environment used by the car.
