Abstract: An exhaust control system for use with a combustion engine is disclosed. The exhaust control system may have an exhaust passage configured to receive a flow of exhaust from the combustion engine, a particulate filter located within the exhaust passage, and an oxidation catalyst located upstream of the filter. The oxidation catalyst may be configured to promote regeneration of the particulate filter and may have an activation temperature range. The exhaust control system may also have a heating device located to selectively warm the oxidation catalyst to within the activation temperature range, and a controller in communication with the combustion engine and the heating device. The controller may be configured to detect a loading of the particulate filter exceeding a first loaded threshold amount, and to detect a low temperature condition of the combustion engine.

Abstract: An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passage configured to receive a flow of exhaust from the combustion engine, a particulate filter located within the exhaust passage, and a heating device located to selectively warm the flow of exhaust passing through the particulate filter. The exhaust system may also have a controller in communication with the combustion engine and the heating device. The controller may be configured to continuously determine an amount of particulate matter within the particulate filter, continuously determine a desired regeneration temperature based on the amount of particulate matter, and continuously determine an error value as a function of the desired regeneration temperature and an actual regeneration temperature. The controller may be further configured to determine an amount of particulate matter within the particulate filter, and adjust an amount of warming provided by the heating device based on the error value.

Abstract: A regeneration system for a work machine may include a power source configured to provide a variable power output. The regeneration system may also include at least one regeneration device operably connected to the power source and adapted to use at least a portion of the variable power output to regenerate the exhaust element. A controller may be configured to determine an amount of power required to regenerate the exhaust element. The controller may also be configured to adjust operation of the power source based on the amount of power required to regenerate the exhaust element.

Abstract: An electrical connection element for providing an electrical connection to a porous material may include a first electrically conductive plate disposed on at least a portion of a first side of the porous material. A second electrically conductive plate may be disposed on at least a portion of a second side of the porous material, opposite to the first side. An electrically conductive material may impregnate the porous material in a region between the first and second electrically conductive plates, and an electrical connector may be attached to at least one of the first and second electrically conductive plates.
