  • Patent number: 9273585
    Abstract: This disclosure relates to a method for controlling a system for regenerating a diesel particulate filter. The method includes monitoring an engine run time that has lapsed since a previous regeneration event. The method also includes monitoring backpressure behind the diesel particulate filter. The method further includes triggering a regeneration flag if the engine run time that lapsed since the previous regeneration event reaches a predetermined time limit and the backpressure exceeds a minimum value.
    Type: Grant
    Filed: June 24, 2014
    Date of Patent: March 1, 2016
    Assignee: Donaldson Company, Inc.

  • Patent number: 8061129
    Abstract: An exhaust system for use with a diesel engine includes a diesel particulate filter configured to capture particulate matter exhausted from the diesel engine, a first sensor operable to detect a particulate matter accumulation level within the diesel particulate filter, and a second sensor operable to detect an ambient temperature of an environment surrounding the diesel particulate filter. The exhaust system also includes a control module electrically coupled to the first sensor, the second sensor, and the diesel particulate filter. The control module is operable to adjust a first regeneration threshold based on the detected ambient temperature. The control module is also operable to initiate regeneration of the diesel particulate filter when the detected particulate matter accumulation level reaches the first regeneration threshold.

  • Publication number: 20070234713
    Abstract: The present disclosure relates to an diesel exhaust treatment device including a main body having a central longitudinal axis that extends between first and second ends of the main body. A catalyzed substrate is positioned within an interior of the main body. A side inlet is positioned at a side of the main body for directing exhaust gas into the interior of the main body. A flow distribution element is positioned within the interior of the main body at a location between the side inlet and an upstream face of the substrate. The flow distribution element extends across a direction of exhaust flow through the main body and is mounted at a side of the main body that is opposite the side inlet.

  • Publication number: 20060277900
    Abstract: The present disclosure relates to a vehicle exhaust system component including first and second conduits having double wall constructions. The first and second conduits are connected to one another at a service joint. An aftertreatment device is mounted within the first and second conduits. The aftertreatment device has a length. The aftertreatment device is positioned within the first and second conduits such that the service joint surrounds the aftertreatment device at an intermediate location along the length of the aftertreatment device.

  • Publication number: 20060067860
    Abstract: The present disclosure relates to a double-wall construction for an engine exhaust conduit. The construction includes an inner conduit and an outer conduit surrounding the inner conduit. An insulating annular gap is defined between the inner and outer conduits. A spacer structure maintains the gap between the inner and outer conduits. The spacer structure can be unitary with at one of the inner and outer conduits.
