Used as catalytic converters of gasoline engines, the honeycomb ceramic catalyst
substrates are coated by catalyst; at the same time , we improve the specific surface
areas and cut down the heat capacity to increase the catalytic function. When the
noxious emissions pass through, HC, CO and NOX will be converted into harmless
components.

Diesel particular filter bases on honeycomb ceramic substrate, whose materials are
cordierite or carborundum. It could trap the particulate matter from diesel exhaust
emissions, so they are applied on cars, buses, trucks and so on.
cordierite or carborundum. It could trap the particulate matter from diesel exhaust
emissions, so they are applied on cars, buses, trucks and so on.
The necessary property of honeycomb ceramic catalyst substrate used in cars as follows:
1).High specific surface area: ensure exhaust gas could contact weigh catalyst enough.
2).Stable water absorption: guarantee catalyst could be firmly and evenly coated on the
surface of substrate, so it's no waste for too thick coating.

3).Warm-up characters:after starting up engine,the temperature of substrate could
reach the active temperature of catalyst in the shortest time.

4).Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it
won’t affect the performance of engine.

5).high intensity: substrates work in bumpy cars, so the intensity of substrates must be
too high to be destroyed.

6).perfect assembly: substrates are parts of exhaust; perfect appearance and exact
dimension could ensure assembly perfect.
