Abstract
A simple low cost smoke filter. It is adapted for use in an internal combustion engine exhaust system. It has a tapered body with a mass of alumina coated wire supported therein. The filter medium is under some longitudinal force created by a pervious support that has an unstressed curved configuration which is flattened against the medium. This is done in order to cause radial compression because of the taper, as well as longitudinal compression thereof.
