Title:
燃料噴射制御装置、及び燃料噴射制御システム
Document Type and Number:
Japanese Patent JP6950489
Kind Code:
B2
Abstract:
To provide a fuel injection control device or the like which can reduce an influence even if fuel injection is performed in an inclination of a rise of an injection rate which is different from a target.SOLUTION: A fuel injection control device 10 controlled by a control device 100 can switch an inclination of a rise of an injection rate at fuel injection from an injection hole 29 by drive energy inputted to a drive part 30. The control device 100 detects a lowering-start time of fuel pressure on the basis of a measurement result of the fuel pressure which is supplied to the injection hole 29, and determines an inclination of a rise of an actual injection rate of the fuel injection on the basis of an injection delay time from an on-time of the drive energy up to the lowering-start time. When the inclination of the actual injection rate is different from a target inclination of the rise of the injection rate, the control device 100 corrects a drive period in which the drive energy is inputted to the drive part 30 at the fuel injection in execution.SELECTED DRAWING: Figure 1
