Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018044513
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device capable of appropriately removing unburned materials accumulated in an injection hole of a fuel injection valve.SOLUTION: A control device 101 comprises an ECU 705 as a control part controlling a fuel injection valve 1. The fuel injection valve 1 has a housing, an outer needle, an inner needle, a driving part, a linking part, and an outer energization member. The ECU 705 has a normal injection mode (A pattern) for injecting fuel under a condition that the outer needle is isolated from an outer sheet part while the inner needle is in contact with an inner sheet part, and an isolation injection mode (B pattern) for injecting the fuel under a condition that the outer needle is in contact with the outer sheet part while the inner needle is isolated from the inner sheet part. It controls driving of the inner needle so that the normal injection mode and the isolation injection mode are switched on the basis of a correction coefficient (E0) indicating the amount of unburned materials accumulated in the injection hole.SELECTED DRAWING: Figure 1
