How a catalytic converter work
To address emissions of toxic gases such as CO, HC, and NO, it has been found that platinum group metals
palladium and platinum exhibit strong catalytic effects on CO and HC, while rhodium has a stronger catalytic effect on CO, HC, and NO.

Catalytic converter disassembly
Basically, a catalytic converter consists of a oxygen sensor plug, a honeycomb substrate, a steel wire mesh mat, stainless steel shells and flage plate. However，our pipeline are exclusive.CIRconvert catalytic converter boasts high-performance conversion status and advanced production technology. It uses high-quality base materials and high-tech coatings to ensure outstanding oxygen storage capacity and high-performance catalytic conversion. Engineered parts are provided by OE professional knowledge and made from high-strength stainless steel materials. It is rugged, durable, and made with high-temperature and durable catalytic materials. We only produce high-quality, high-performance, and high-end automotive components.
The catalyst is composed of a substrate, rare earth elements, and precious metals (palladium, platinum,rhodium).
The material of the inner lining pad is typically an expansion mat or steel wire mesh pad, serving the purpose of sealing, insulating, and securing the substrate to prevent damage caused by vibration, thermal deformation, and other factors.
T409 stainless steel sheets to prevent oxidation and the resulting shedding of material, which could lead to blockage of the substrate.
Ultra-high hole positioning perforation technology, leads the oxygen sensor to sending more precise electrical signal to the electrical control unit, so as to more accurately control the automobile injector nozzle fuel injection, which achieve the purpose of reducing fuel cost.
