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.
