The catalytic converter is coated with rare earth element and noble metals of 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. Along with the Europe III, IV emissions implementation, our factory has carried on the optimized design in the original formula foundation, developed a series of combustion initiation temperature to be lower, the transformed efficiency was higher.
We can supply both metal Honeycomb Substrate coated with noble metals of Pt, Pd, Rh and without noble metals. We produce catalysts which are suitable for car or motorcycles in all types and can meet the emission standard Euro II, Euro III, Euro IV and Euro V.
Metallic substrate can withstand temperatures of up to 1300 ºC. Metallic substrates have honeycomb-like structures with thousands of parallel channels. The walls of these channels provide the surface to convert harmful emissions into carbon dioxide, nitrogen and water vapor.
