An open end diesel particulate trap for removing particulates from the exhaust gas stream of the diesel engine includes a housing having an inlet opening, an outlet opening and a gas outlet and an exhaust gas path extending from the inlet opening to the gas outlet. A first portion of the exhaust gas path leads from the inlet and extends at an angle to a second portion of the exhaust gas path leading to the gas outlet. A filter element is disposed in the housing and includes a central aperture defining the first path portion. The filter element has a wall of filter material surrounding the central aperture through which the second path portion extends. A particulate reservoir is in communication with the outlet opening. When exhaust gas flows from the inlet opening to the gas outlet, particulates in the exhaust gas flowing along the first path portion can fall into the reservoir and particulates in the exhaust gas flowing along the second path portion can be trapped in the filter element wall.
