Honeycomb Ceramic for gasoline engine exhaust
1.Function
The main harmful gases from the vehicle are carbon monoxide (CO), nitrogen oxides (NO), hydrocarbons (HC). When coated with catalysts, honeycomb ceramic is applied in the 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.
