Title:
FUEL INJECTION VALVE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2017133454
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To minutely control time change of a fuel injection amount when a solenoid valve (fuel injection valve) is shifted from a valve close state to a valve open state.SOLUTION: A fuel injection valve control device includes a pulse generation section (102) for generating a voltage pulse applied to a solenoid valve (150) as a fuel injection valve, a duty ratio setting section (132) for setting a duty ratio of the voltage pulse, and voltage amplitude control sections (120 and 134) for controlling a voltage amplitude of the voltage pulse applied to the solenoid valve. When the solenoid valve is shifted from a valve close state to a valve open state, the duty ratio and/or the voltage amplitude value of the voltage pulse applied to the solenoid valve is varied in a predetermined mode.SELECTED DRAWING: Figure 1
