This product is a wall-flow type honeycomb ceramic filter in special structure and material. It is applied in exhaust purifier of diesel engine. This product screens and catches soot particles in diesel vehicle exhaust by aperture gap on the aperture wall of wall-flow type filter, so as to purify diesel vehicle exhaust. The product is made of two materials: cordierite and silicon carbide.
