  • Publication number: 20210017929
    Abstract: A control device for controlling an engine provided with a fuel pump including a pressurizing chamber, a plunger inserted into the pressurizing chamber and which changes a volume of the pressurizing chamber, and an on-off valve configured to open and close a suction port, is provided. When a pressurizing cycle consists of a period of pressurizing stroke in which the volume of the pressurizing chamber is reduced to allow fuel to be pressurized and a period of suction stroke in which the volume of the pressurizing chamber is increased to allow fuel to be drawn into the pressurizing chamber, a closing cycle of the on-off valve is controlled so that a ratio of the closing cycle to the pressurizing cycle becomes smaller in a second combustion mode where a partial compression-ignition combustion is performed than in a first combustion mode where SI combustion is performed.

  • Patent number: 10876490
    Abstract: A controller for controlling a fuel injection valve and a fuel pressure adjustment mechanism sets an air-fuel ratio of a fuel-air mixture to be generated within a combustion chamber to be equal to or leaner than a theoretical air-fuel ratio, based on an operating condition of an engine; drives the fuel injection valve, based on the set air-fuel ratio; estimates a deposition amount of deposits on an injection hole of the fuel injection valve, based on an operating condition of the engine; causes the fuel pressure adjustment mechanism to increase the fuel pressure, when the estimated deposition amount of deposits exceeds a predetermined value; and restricts the fuel pressure from increasing, even when the estimated deposition amount of deposits exceeds the predetermined value, as long as the fuel-air ratio is set to an air-fuel ratio leaner than the theoretical fuel-air ratio.

  • Patent number: 10860890
    Abstract: A learning management device comprising an inference engine that is input with image data and acquires output for performing guidance display to a user using an inference model that has been specifically learned, and a processor that confirms if there is a specified relationship between a trial input image and trial guidance display for this trial input image under conditions that have been assumed at the time of use, and that determines whether or not it is necessary to relearn the inference model that has been learned based on the result of this confirmation.

  • Publication number: 20200370500
    Abstract: A controller for controlling a fuel injection valve and a fuel pressure adjustment mechanism integrates a deposition amount of deposits per unit time, and estimates a deposition amount of deposits on an injection hole of the fuel injection valve. The controller causes the fuel pressure adjustment mechanism to increase a fuel pressure, when the estimated deposition amount exceeds a predetermined value, and corrects the unit deposition amount acquired by the deposition amount estimation according to the set fuel injection timing of the fuel injection valve. The controller corrects such that as compared with the unit deposition amount when the fuel injection timing is set to a first timing away from a top dead center of the piston by a first period, the unit deposition amount decreases when the fuel injection timing is set to a second timing away by a second period longer than the first period.

  • Patent number: 10746254
    Abstract: An intermediate member includes first and second intermediate members. The first and the second intermediate members are provided with a spring supporting portion that extends along springs and supports the springs from an outer side. An expansion and contraction of the springs enables the intermediate member to be movable in a circumferential direction. Accordingly, sliding distances caused by the expansion and contraction of the first and the second springs become shorter, compared with a configuration where the first and the second spring are supported by the driven member or drive member from the outer side, thereby decreasing an energy loss (hysteresis) caused by the sliding. As a result, a vibration damping performance of the damper device can be improved.
