Auto&Motorcycle Exhaust System Metal Honeycomb Substrate

We mainly produce Metal Catalytics and Ceramic Catalytics for Auto and Motorcycle exhaust system, like Honeycomb metal substrate catalytic converter. Metallic substrate is with the advantages of fast burning, small volume, high mechanical strength, prominent heat-resistance, etc. It is widely used in exhaust gas purification, especially for motorbike. High strength complex substrate plus big surface area and active element of noble metal could lower down pollutant value of motorcycle exhaust efficiently, such as CO, HC, NOX etc...And such kind of catalyst is of excellent catalytic activity and durability that could reach Euro emission standard IV, meet requirement as per customers' requests. Metallic substrate should be pretreated in order to generate a transition layer which is required to solve the mismatched heat expansion between metallic substrate itself and the active layer. On the transition layer, it is coated with rare earth catalyst, while in active layer is coated with noble metal like PT, Pd, Rh. When the engine exhaust passing through the three-way catalytic converter the elements of CO would be oxidized into CO2, the HC is turned into H2O and CO2, while the NOX is deoxidized into nitrogen. The catalytic converter substrate is made of metal honeycomb with stainless steel crust and Fe-Cr-Al honeycomb body. It is a critical part of motorcycles and off-road engines to make the exhaust emission meet government standard.



Features:
*Low thermal expansion
*High surface area
*Long-term durability performance
*Low pressure drop
*Good thermal shock resistance
*Combined with the EGR systems to help different vehicles to satisfy emission standard
*Low light-off temperature
*Excellent adhesion between wash-coat and susbstrate with netty structure

Usage:
For exhaust system of auto engine, like Honda, Suzuki, Toyato, BMW, etc. And Diesel engine, like farm machinery and construction machinery: Tiller, Harvester, Rice transplanter, Planter, Rice mill, Weeder, Thresher, hoisting machinery, excavator, Reinforced concrete machinery.






Durability:
Metal catalyst: 100, 000 KM. However, Ceramic catalyst: 80, 000 KM

Specification:
*cylinder/round shape, Size: Dia 110mm~155mm, Hight: 40mm~150mm, Cell: 100~600CPSI
