Motorcycle Exhaust Catalyst Metal Honeycomb Substrate

The metallic honeycomb substrate 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. It is a critical part of motorcycles and off-road engines to make the exhaust emission meet government standard.

On the surface of the metallic substrate, coated with high surface area and good thermal stability washcoat with less precious metals such as platinum, palladium and rhodium, which are used for purifying of unburned hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOX) form the internal combustion engine. The cells of honeycomb density can be 100, 200, 300, 400 or 600 cpsi and more. The shape will be round, oval, racetrack or other special.
