Does the original three-way catalytic converter have a designated code?
1 Answers
Original three-way catalytic converters all have designated codes, as original vehicle parts are strictly selected, installed, and coded. Composition of the three-way catalytic converter: The three-way catalytic converter generally consists of four parts: the shell, vibration damping layer, carrier, and catalyst coating. Shell: Made of stainless steel to prevent oxide scale from falling off, which could cause blockage of the carrier. Vibration damping layer: Composed of gaskets or wire mesh pads, it serves to seal, insulate, and fix the carrier. To protect the carrier from damage due to vibration, thermal deformation, and other factors, the gasket is made of expanded mica and aluminum silicate fiber, bonded with adhesive. Carrier: Made of honeycomb-shaped ceramic material, though many also use metal (including stainless steel) materials. Catalyst: Composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the carrier to form the purifying agent. Lifespan of the three-way catalytic converter: The lifespan of a three-way catalytic converter is generally between 80,000 to 100,000 kilometers. The specific lifespan depends on the vehicle's usage conditions and is also related to the quality of fuel used and the driving environment.
