  • Patent number: 9441524
    Abstract: Various systems and methods are described for an engine system with an exhaust gas treatment system including a particulate filter. In one example method, accumulated hydrocarbons are removed from the exhaust gas treatment system by increasing an exhaust gas temperature to a first temperature responsive to a particulate filter regeneration request during extended cold idle operation. After a predetermined duration, the exhaust gas temperature is increased to a second, higher temperature to regenerate the particulate filter.

  • Patent number: 8607549
    Abstract: In one approach a method for operating an engine including a DPF is provided. The method includes adjusting a post fuel injection amount based on a rate of change of engine torque during DPF regeneration. As one example, the adjusting includes reducing the amount when the rate of change is positive, and increasing the amount when the rate of change is negative. Furthermore, the method may also include delivering exhaust gas to a turbocharger turbine, to an oxidation catalyst, and then a DPF, the adjusting of the post fuel injection further based on thermal inertia of the turbocharger.

  • Patent number: 8539824
    Abstract: Methods for monitoring and detecting undesired exotherms which may occur in an exhaust aftertreatment system coupled to a lean burning combustion engine are described. In one particular approach, an undesired exotherm may be indicated based on an expected oxygen depletion along a length of an exhaust aftertreatment system in the direction of exhaust gas flow of exhaust gas. For example, during DPF regeneration, a certain amount of oxygen is expected to be utilized for removing soot. If less oxygen is actually found in the exhaust downstream of the exhaust system, then an undesired exotherm may be present, as unintended reductant may be present in the exhaust and reacting exothermically with oxygen. Various mitigation actions may then be initiated in response to the indication of an undesired exotherm.

  • Publication number: 20130076007
    Abstract: A pick-up truck comprises a chassis, a rear axle attached to the chassis, a passenger cabin, a cargo bed, a trailer hitching structure, and a first image capturing device. The passenger cabin is attached to the chassis forward of the rear axle. The cargo bed is attached to the chassis over the rear axle. The trailer hitching structure is attached to the chassis at a position rearward of the vehicle occupant structure and has a trailer engaging portion accessible within the cargo bed. The first image capturing device is attached to the passenger cabin. The first image capturing device is mounted in a manner allowing the first image capturing device to capture an image of the trailer engaging portion of the trailer hitching structure.

  • Publication number: 20120023910
    Abstract: Systems and methods for controlling regeneration of a diesel particulate filter in a vehicle engine exhaust include detecting a distance of an object from the exhaust and controlling a regeneration event if the distance is less than a threshold value. The system and method may include a particulate filter disposed in the exhaust of the vehicle and a proximity sensor disposed adjacent an exhaust opening and positioned to detect presence of an object near the opening. A controller in communication with the proximity sensor is adapted for controlling regeneration of the particulate filter in response to the proximity sensor detecting the object near the opening.
