In order to meet the requirements of future emission regulations, we will focus on the catalytic materials used in the key technology of gasoline vehicle particle trapping (GPF), carry out the engineering technology development of high-temperature and low-temperature dense-type catalysts for low-precious metals, and focus on the key technologies of catalytic converters for gasoline vehicles. Catalytic materials, research on high performance composite rare earth coating materials, research on high oxygen storage capacity and thermal stability synthesis methods, etc.; research on TWC+GPF system integration and matching calibration technology; Developed integrated technologies for activated carbon products, key materials, and fuel evaporation control systems.
