Abstract
A device that filters particulate matter from the exhaust stream of an engine includes a supporting structure with an elongate support, and a filter sleeve disposed within an exterior sleeve; a filter sleeve comprising a tubular shaft of filter material, the shaft having an open first end, and a closed second end; an exterior sleeve comprising a tubular shaft that defines an internal cavity that is sized and proportioned to receive the filter sleeve, the tubular shaft having an open first end, and a substantially closed second end, the substantially closed second end having a hole for filtered exhaust gases to pass through; and an attachment member that mounts the exterior sleeve to the supporting structure.
Claims16
A device for filtering particulate matter from exhaust gases, the device comprising:
- a supporting structure comprising an elongate support;
- a filter sleeve comprising a tubular shaft of filter material, the tubular shaft having an open first end, and a closed second end;
- an exterior sleeve that defines an internal cavity that is sized and proportioned to receive the filter sleeve, the exterior sleeve having an open first end, a side wall that surrounds the internal cavity, and a second end, wherein the side wall is air permeable, and the second end comprises an end wall that defines a hole for filtered exhaust gases to pass through;
- and
- an attachment that mounts the exterior sleeve to the supporting structure.
A method of removing particulate matter from exhaust gases of an engine, the method comprising:
- providing a filter sleeve received within an exterior sleeve, wherein:
- the filter sleeve comprises a tubular shaft of filter material, the tubular shaft having an open first end, and a closed second end;
- and
- the exterior sleeve defines an internal cavity that is sized to receive the filter sleeve, the exterior sleeve having an open first end, and a second end, the second end comprising an end wall that defines a hole for filtered exhaust gases to pass through;
- positioning the exterior sleeve in line with an exhaust pipe of the engine emitting the exhaust gases;
- and
- using an elongate support, supporting the exterior sleeve on a ground surface such that the exterior sleeve and filter sleeve are supported by the elongate support separately from the exhaust pipe.
