Improved emission control apparatus for use with a diesel engine which may include an enclosed cylindrical housing having an inlet and an outlet. A particulate trap is disposed in the housing between the inlet and outlet for collection and removal of particulates from the engine exhaust. The particulate trap includes an upstream section of reduced diameter and a downstream section of a diameter greater than the cylindrical housing to form an annular pocket therearound. The upstream section is provided with peripheral walls in which are provided uniformly spaced, longitudinally disposed, slotted apertures.
