The gasoline engine tail gas purifier carrier coated with catalyst is suitable for
and is currently one of the most
for gasoline engine discharge of tail gas in motorized vehicles. Our honeycomb
ceramics are characterized by unique honeycomb structure, low expansion coefficient,
good thermal stability, large specific area and low pressure loss, and reach
domestic advanced level.
