China Car Purifer Metallic Honeycomb Substrate

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.
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 3, meet customers' requirements.
metal-based monolith substrate offers many advantages in comparison with a ceramic one, for instance:
1) Shorter light off time
2) Less risk of overheating
3) Less back pressure
4) Larger effective area
5) Greater catalytic capacity
6) Smaller and more flexible design
7) Thinner walls
8) Higher mechanical strength
9) Better resistance to thermal shock
