Abstract: A locking spacer assembly for mounting on an elongated member and a method of use thereof are disclosed. A first element with a first end and a second end fits over the elongated member with the first end, which may be beveled, facing outwards. A second element with a beveled end fits over the elongated member with the beveled end facing inwards toward the beveled end of the first element. Finally, a flexible member fits over the elongated member between the first element and the second element. The flexible member has a cross-section selected to be compressed and fit within a space formed when the first element and second element are compressed together on the elongated member so that the compression of the flexible member secures the locking spacer assembly to the elongated member so long as the compression is maintained.

Abstract: A filter regeneration system for an internal combustion engine operable at an engine speed and having: a gas exhaust system for fluidly expelling exhaust gas at an exhaust gas temperature; and at least one filter arrangement in fluid communication with the gas exhaust system and configured to capture particulate in the exhaust gas. The regeneration system includes: a load generating arrangement in operable communication with the internal combustion engine and configured to modify the mechanical load on the internal combustion engine, thereby changing the exhaust gas temperature; and at least one controller in electrical communication with at least a portion of the load generating arrangement and configured to control at least one operating parameter of the load generating arrangement. A method of regenerating a filter arrangement is also disclosed.
