ABSTRACT:
A new filter structure is provided for removing particles from the exhaust gas of a large, single piston engine of low RPM, before passing the exhaust gas through a turbine for the purpose of driving a supercharger. The filter is so constructed as to be able to efficiently and reliably perform its filtering function over long periods of time in the high temperature environment of the piston engine exhaust. It comprises a cylindrical shaped housing having at one end longitudinally extending slits distributed around its circumference and at the other end an annular flange for mounting the filter in the exhaust line. The housing encloses a filter element comprising a hexagonal stacked array of cylindrical tubes and said filter element is retained in said housing by means of multiple resilient brackets, each formed in the shape of an open elongated loop so as to conform generally to the contour of the filter element on one hand and the inside of the housing on the other. Some of the slits in the housing align with the open ends of the brackets and the remaining slits are positioned between the brackets. The flexibility inherent in the shape of the brackets, combined with the flexibility provided by the cooperation of the slits in the housing with the open portions of the brackets, results in excellent capability for expansion, due to high temperatures, in the plane of the filter element. The entire assembly is preferably furnace brazed.
