Abstract: An after-treatment device that includes a diesel particulate filter (DPF) requiring periodic regeneration includes a sensor providing a signal indicative of a soot accumulation and at least one device providing an operating parameter indicative of a work mode of the machine. A controller determines a soot level and a readiness level based on the work mode of the machine, and further classifies the soot level relative to a desired range for initiating a regeneration event and initiates the regeneration event when the soot level falls within the desired range.

Abstract: In one aspect, the present disclosure is directed to a particulate trap regeneration temperature control system. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow of an engine. The system may also include a heating system configured to increase the temperature of the particulate trap. The system may further include a controller configured to control operation of the heating system during execution of a thermal regeneration event of the particulate trap. The controller may control operation of the heating system by effectuating a first temperature increase of the particulate trap at a predetermined rate up to a first predetermined temperature. The controller may also be configured to effectuate a first temperature hold by maintaining the temperature of the particulate trap at the first predetermined temperature for a predetermined amount of time.

Abstract: A system for ventilating a crankcase of an internal combustion engine includes an exhaust system having a treatment element, and the treatment element includes a catalyst configured to assist in passively regenerating a filter of the exhaust system. The system for ventilating the crankcase also includes first flow path configured to transmit a first flow from the crankcase to a port upstream of the filter, and a second flow path configured to transmit a second flow from a combustion chamber of the internal combustion engine to the exhaust system. The catalyst is configured to treat a combined flow comprising the first flow and the second flow.
