Publication number: 20230213433Abstract: Apparatus and methods are disclosed which are capable of being used to determine filtration efficiency of a filter body even in a clean state. Methods of determining a filtration efficiency of a filter including forcing an inlet flow comprised of a gas (such as air) flow into the inlet end of the filter at a set flow rate, introducing particles such as smoke particles into the inlet flow, and optically counting the number of particles entering and exiting the filter during a sampling event, such as with diffraction based optical particle counters positioned upstream and downstream of the filter. Preferably the gas flow is a soot-free flow stream which does not load the honeycomb filter body with contaminants that need to be removed or burned out. The filter body can thus remain in an essentially clean state even after testing its filtration efficiency.Type: ApplicationFiled: July 8, 2020Publication date: July 6, 2023Inventors: Joseph Henry Citriniti, Curtis Robert Fekety, Christopher Lane Kerr, Stefan Wolfgang Kramel, Huiqing Wu, Xinfeng Xing
