The three-way catalytic converter, also called "catalytic converter", is the main component that purifies pollutants emitted by automobile engines. Its structure consists of shell, liner and carrier from outside to inside. The outer shell mainly plays the role of protecting the core. The pad mainly plays the functions of fixing the carrier, buffering and heat insulation. A good pad can effectively protect the carrier. The core of the three-way catalytic converter is the carrier, which is usually a honeycomb-shaped ceramic cylinder. The carrier is coated with precious metal catalysts (platinum, rhodium, palladium, etc.). The exhaust gas passes through these small holes to achieve catalytic conversion.
