The three-way catalytic converter needs to be cleaned, and the cleaning method for the three-way catalytic converter is to use a hanging bottle. This method connects a plastic hose to the engine vacuum solenoid valve and relies on the air pressure in the hollow tube to suck the cleaning agent from the infusion bottle into the engine. When the cleaning agent is discharged from the exhaust pipe, it cleans the three-way catalytic converter.[/prisna-wp-translate-show-hide
Composition of three-way catalytic converter:
A three-way catalytic converter generally consists of four parts: a shell, a damping layer, a carrier, and a catalyst coating.
The shell is made of stainless steel to prevent oxide skin from falling off and causing blockage of the carrier.
The vibration damping layer is composed of a cushion or a steel wire mesh cushion, which plays a role in sealing, insulation, and fixing the carrier. In order to prevent damage to the carrier caused by vibration, thermal deformation, and other factors, the cushion is composed of expanded mica and aluminum silicate fibers, and finally bonded with adhesive.
The carrier is made of honeycomb shaped ceramic materials, and many also use metal (including stainless steel) materials.
The catalyst is composed of precious metals such as platinum, rhodium, and palladium, which are sprayed onto the carrier to form a purifying agent
