    摘要: Various embodiments of an apparatus, system, and method are disclosed for managing regeneration event characteristics. For example, according to one embodiment, an apparatus for controlling the temperature of the output exhaust of an internal combustion engine for a regeneration event on a particulate matter filter includes a regeneration module, a turbocharger thermal management module, a fuel injection thermal management module, and an air intake thermal management module. The regeneration module determines a desired particulate matter filter inlet exhaust gas temperature for a regeneration event. The turbocharger thermal management module determines a variable geometry turbine (VGT) device position strategy. The fuel injection thermal management module determines a fuel injection strategy. The air intake thermal management module determines an intake throttle position strategy. The VGT device position strategy, the post-injection fuel injection strategy, and the intake throttle position strategy cooperatively achieve the desired particulate matter filter inlet exhaust gas temperature and maintain a fuel dilution level of the engine below a maximum fuel dilution level.

    摘要: Various embodiments of an apparatus, system, and method are disclosed for managing regeneration event characteristics. For example, according to one embodiment, an apparatus for controlling the temperature of the outlet exhaust of an internal combustion engine for a regeneration event on a particulate matter filter includes a regeneration module and a fuel injection strategy module. The regeneration module is configured to determine a desired engine outlet exhaust gas temperature for a regeneration event. The fuel injection strategy module is configured to determine a regeneration fuel injection strategy for achieving the desired engine outlet exhaust gas temperature. The regeneration fuel injection strategy includes a main fuel injection, a first heat post-injection, and a second heat post-injection. In certain implementations, the fuel injection strategy also includes at least one or two non-heat post-injections for achieving a desired particulate filter inlet exhaust gas temperature.

    摘要: A method is disclosed for thermal management of an engine comprising a continuously variable transmission. The method includes an engine capability module storing a torque-speed map comprising a first region where the engine inefficiently regenerates an aftertreatment device, a second region where the engine efficiently regenerates the aftertreatment device, and a third region where the engine is not capable of regenerating the aftertreatment device. The method further includes an aftertreatment determination module determining a regeneration index, an operating conditions module determining an engine speed and an engine load, and a speed-load adjustment module adjusting a speed-load target. The method further includes the speed-load adjustment module adjusting the speed-load target to a preferred region along equal power curves of the torque-speed map based on the regeneration index.
