PARTICULATE FILTERS FOR USE WITH DIESEL ENGINES |
摘要 |
A diesel particulate filter for removing particulates from the exhaust gases of smaller displacement light duty vehicle diesel engines (about 3.0 liters or less cylinder displacement or more refined larger engines) which typically generate particulates at an average rate of about 0.45 gm./mile or less in a normal driving cycle comprising a honeycomb structure formed by a matrix of thin interconnected porous walls defining a multiplicity of cells extending, in preferred embodiments, in a substantially longitudinal and mutually parallel fashion through the filter. An inlet group of the cells is open at and define an inlet open end face of the filter. An outlet group of the cells is open at and define an outlet end face of the filter. The inlet cells are closed adjacent to the outlet end face and the outlet cells are closed adjacent to inlet end face. The volume of the thin wall internal open porosity and the mean diameter of the pores forming the thin wall internal open porosity lie within the area defined by the boundary lines connecting the points A-B-C-D in FIG. 5. |
