Product overview:
　　Diesel particulate filler (DPF) is a kind of silicon carbide as raw material flow honeycomb ceramics, main componet containing diesel vehicle tail gas discharged by the engine is the carbon particles, particulate trap is installed in the system of diesel engine in automobile exhaust gas through the filter, reduce exhaust particulate matter(PM) device above, The DPF working principle: through the holes at both ends by altemating honeycomb porous ceramic filtration to remove PM, to use wall hole ceramics.
