ABSTRACT:
A particulate trap for use in a diesel engine which is inexpensive, and which is high in particulate trapping efficiency, regeneration properties and durability, and low in pressure loss due to particulates trapped. An even number of flat filters made from a non-woven fabric of heat-resistant metallic fiber are laminated alternately with the same number of corrugated sheets made of a heat-resistant metal. The laminate thus formed are rolled into a columnar shape. Each space between the adjacent flat filters in which every other corrugated sheet is inserted is closed at one end of the filter element by a closure member. The other spaces between the adjacent flat filters are closed at the other end of the filter element.
