    摘要: A particulate filter regeneration system is provided for regenerating a filter at low vehicular speeds. The power source is selectively coupled to a transmission unit so that the transmission unit can be at least partially decoupled from the power source. An exhaust passage having a particulate filtering device is configured to release exhaust from the power source into the atmosphere. In addition, a controller is configured to determine at least one power source parameter indicative of an exhaust temperature, at least partially decouple the power source from the transmission unit in response to the determination, and increase a power source speed in response to the determination.

    摘要: A system is provided for monitoring exhaust gas concentrations in an exhaust stream from an engine. The system may include the exhaust system configured to carry an exhaust stream generated by the engine. The system may further include at least one sensor in communication with the exhaust stream and configured to generate an output indicative of a concentration of NOx and a concentration of at least one sulfur-containing compound in the exhaust stream. The system may further include a controller configured to selectively produce one of a rich condition and a lean condition in the exhaust stream and to determine, during the rich condition, the concentration of the at least one sulfur-containing compound in the exhaust stream based on the output from the at least one sensor and to determine, during the lean condition, the concentration of NOx in the exhaust stream based on the output from the at least one sensor.

    摘要: A method is provided for operating a regeneration assembly to regenerate a filter assembly during a regeneration cycle, and for supplying fuel to at least one fuel injector unit associated with the regeneration assembly during the regeneration cycle. The method includes dispensing a cleaning substance into a fluid flow path associated with the regeneration assembly during a cleaning cycle. The method further includes directing the cleaning substance through the at least one fuel injector unit during the cleaning cycle.

    摘要: An exhaust treatment system is provided. 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 catalyst configured to chemically alter at least one component of the exhaust flow. Further, the system may include an exhaust conduit configured to direct the exhaust flow from the engine to the particulate trap and the catalyst. In addition, the exhaust treatment system may include a heating system configured to maintain the temperature of the catalyst above a first predetermined temperature. The heating system may also be configured to periodically raise the temperature of the particulate trap above a higher, second predetermined temperature to thereby effectuate a regeneration of the particulate trap by oxidizing particulate matter accumulated in the particulate trap.
