More Product Information

Honeycomb Ceramic Catalyst Substrates

The main harmful gases from the vehicle are carbon monoxide (CO), nitrogen oxides (NO), hydrocarbons (HC).coated with catalysts, honeycomb ceramic is applied in catalytic converter of gasoline vehicle to catalyze, convert and purify the exhaust to CO2,water,nitrogen to making vehicle exhaust reaching standards of Euro IV and Euro V.
