Abstract (en)
An apparatus, including a diesel particulate filter, at least one sensor for sensing information associated with operation of an engine, an engine brake configured to brake the engine, and a controller electrically coupled to the at least one sensor and the engine brake, to determine if the engine is operating in a manner that does not generate enough engine heat to activate the diesel particulate filter, and if the engine is so operating, operate the engine brake so as to brake the engine to cause the engine to generate enough engine heat to activate the diesel particulate filter. An associated method is disclosed.
