​Automobile Exhaust Emission Catalyst EU4/5/6 Honeycomb Ceramic/Metal Substrate

Car Exhaust Catalyst

Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic substrate body able to withstand high temperatures.

The preferred catalyst support structure is a honeycomb configuration which includes a variety of unobstructed parallel channels sized to through gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. The ceramic substrate is made of cordierite, The cells density can be 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi. The shape of ceramic substrate is round, racetrack, ellipse and other special shape according to the customer’s requirement.

Car exhaust catalysts can efficiently convert harmful hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) in the exhaust gas of gasoline vehicles into harmless water (H2O), carbon dioxide (CO2) and nitrogen (N2) through oxidation-reduction reactions.

WFEC has developed a series of Catalysts to meet Euro V/VI regulations, non-road mobile machinery Tier IV and beyond emission regulations. WFEC dedicates to developing advanced wash-coating technologies to effectively convert HC, CO, NOx and PM to H₂O, CO₂ and N₂. WFEC has been commercialized automobile exhaust emission catalysts for more than 15 years.
