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

Car Exhaust Catalyst

WEIFU has been engaged in the development and manufacturing of catalysts for a wide range of applications that protect the air we breathe. Catalyst expertise helps WEIFU become the leading catalyst supplier in China. Car Exhaust Catalyst is capable of destroying over 90% of Hydrocarbons (HC), Carbon Monoxide (CO) and Nitrogen Oxides (NOx) produced by gasoline engines.

This catalyst technology uses WEIFU's patented washcoat technology, which precisely places the precious metals within the washcoat, resulting in several important benefits:

Optimal use of precious metals

Lower cost and higher effectiveness

Higher conversions of CO, HC and NOx over a wide range of conditions
