China Euro2-Euro5 Motorcycle Car Exhaust System Honeycomb Metal Catalytic Converter

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.
Major technical parameters:
Substrate: metal honeycomb substrate (Fe-Cr-Al alloy);
Light-off temperature: CO≤ 200° C, HC≤ 200° C, NOX≤ 200° C;
Coating losing rate ≤ 3%;
Conversion rate: CO≥ 90%, HC≥ 90%, NOX≥ 80%
The Features of metal honeycomb substrate:
*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
*Excellent quality and competitive price.
