An actuation time is determined based on each of the open time, the open delay time, and the close delay time. The actuation time relates to a time that the coil must be energized so as to cause the injector to inject the first quantity of reductant. A switching command signal is transmitted to the injector to energize the coil for the calculated actuation time so as to cause the injector to inject the first quantity of reductant into an exhaust gas stream.

  • Patent number: 10415453
    Abstract: An active regeneration method for a gasoline particulate filter includes determining if a particulate filter soot load level is greater than a predetermined soot load level threshold and, if so, determining if the particulate filter's temperature is greater than a predetermined burn off temperature threshold. A particulate filter heating phase is initiated when the particulate filter's temperature is not greater than a predetermined burn off temperature threshold and a soot burning phase is started when the particulate filter's temperature is greater than a predetermined burn off temperature threshold.

  • Patent number: 10415454
    Abstract: A control system is provided for thermal management of an aftertreatment device in an engine that is provided in an enclosure. The engine has a cooling fan that is operable in a first direction to cool said engine. The fan is also operable in a reverse direction opposite to the first direction. The control system includes a first temperature sensor that measures a temperature of the engine or the enclosure. The control system further includes a second temperature sensor that measures a temperature of the aftertreatment device. The control system also includes a processor that is coupled to the first and second temperature sensors. The processor is configured to issue control signals, based on whether regeneration is required by the aftertreatment device or not, for selectively controlling a direction of operation associated with the cooling fan.

  • Patent number: 10415457
    Abstract: Techniques for setting a boost target for a turbocharged engine comprise (i) operating the engine in a scavenging mode such that opening of intake and exhaust valves of cylinders of the engine overlap and (ii) while transitioning the engine in/out of the scavenging mode: determining an engine torque request, creating a torque reserve by setting independent targets for throttle inlet pressure (TIP) and intake manifold absolute pressure (MAP), determining a target TIP based on a target total air charge, engine speed, and a previously-determined target engine volumetric efficiency (VE), controlling a wastegate valve based on the target TIP, determining a target MAP based on the engine torque request, and controlling a throttle valve based on the target MAP. During steady-state scavenging operation, the controller calculates a conventional target TIP based on the engine torque request and controls the wastegate valve based on the conventionally calculated target TIP.

  • Patent number: 10415460
    Abstract: A control device for an internal combustion engine, in which vibration of a waste gate valve in a fully closed state and disadvantages caused due to the vibration thereof while the internal combustion engine is running are prevented, and valve opening responsiveness of the waste gate valve can be improved. In a control device for an internal combustion engine, an opening degree of a waste gate valve 14 is controlled by controlling an electrification duty ratio Iduty of the motor 31. In addition, a fully closed period duty ratio IdFC, which is an electrification duty ratio Iduty when the opening degree of the waste gate valve 14 is controlled to be in a fully closed state, is controlled such that the fully closed period duty ratio IdFC becomes smaller when a detected engine speed NE of an internal combustion engine (1) increases (Step 7 in FIG. 5, FIG. 7).
