Catalysis device adopts the metal honeycomb substrate as the carrier, use metal as the main composition of the stabilizer, which coating the active oxide of rare-earth complex cover, and make rare-earth and little noble metal as catalyst, by burned and drying out to complete. Catalysis devices outer shell adopts corrosion resistant plate presure forming, encapsulation welding to complete. It is using the imported cushion to be apart and fix between the carrier and shell, for heat insulation and shock absorption, and it also has good capability in prevent from thermal shock.
Due to the catalysts proporting is fitting, so the conversion rate of dusty gas is high. Meanwhile, the three effect type catalysis device is applicable to the closed loop electricity-gushed system(EFI), new vehicle and replacing vihicle, the unleaded gas that catalysis device was requested to use, the leaf of content is below 5MG/L, otherwise would affect the service life of the catalysis device.
