摘要： An exhaust gas filter for passing exhaust gas of a diesel engine or the like therethrough, thereby removing particulate matter from the exhaust gas. By suitably controlling physical properties of the exhaust gas filter such as a thermal expansion coefficient, the durability of the exhaust gas filter can be enhanced. When a constituent material for the exhaust gas filter includes aluminum titanate as a primary component, the durability can be further enhanced.

摘要： An exhaust gas filter having a ceramic filter body is configured such that a specific heat h (cal/g.degree. C.) of ceramic powder constituting the body, and a bulk specific gravity d (g/cm.sup.3) of the filter, satisfy the relation 0.12 (cal/cm.sup.3 .degree. C.).ltoreq.h.times.d.ltoreq.0.19 (cal/cm.sup.3 .degree. C.). The ceramic filter body includes a plurality of cells which extend axially to open at opposite ends of the body. One of the opposite axial ends of each of the cells is closed by a filler in such a manner that the closed ends of the cells and the open ends of the cells are arranged in an alternating configuration. The filter traps particulates in the exhaust gas, and the trapped particulates are removed by regeneration combustion of the filter. The filter exhibits excellent durability, thus preventing the formation of cracks in the surface and interior of the filter. When the filter is mounted on a diesel engine, the diesel engine advantageously does not discharge black smoke.
