Title:
FUEL INJECTION VALVE DRIVING SYSTEM
Document Type and Number:
Japanese Patent JP2015007371
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel injection valve driving system for enabling the injection of fuel in appropriate amount for a required injection amount by setting the length of an energizing time for a fuel injection valve to be as appropriate as possible for the actual voltage of a capacitor at the time of starting energization.SOLUTION: A fuel injection valve driving system 10 includes a driving circuit 13 using a battery 30 and a capacitor 12 separately as power supplies for controlling power supply from the battery 30 or the capacitor 12 to a fuel injection valve 20 to give opening/closing operation to the fuel injection valve 20, and an ECU 14 for setting an energizing time for the fuel injection valve 20. The ECU 14 sets the energizing time for the fuel injection valve 20 on the basis of an interval between the time of starting energization of another fuel injection valve of which energization is started right before and the time of starting energization of the fuel injection valve 20.
