Title:
FUEL INJECTION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019206943
Kind Code:
A
Abstract:
To suppress deterioration of fuel economy and emission, in a fuel injection system in which a plurality of fuel injection valves are provided to one cylinder.SOLUTION: A fuel injection system comprises: a plurality of fuel injection valves 20 which are provided while being made to correspond to respective intake ports 18, respectively, in an engine 10 in which a plurality of the intake ports 18 are provided to one cylinder; and an injector drive circuit for driving the respective fuel injection valves 20 by energization to the plurality of fuel injection valves 20. When fuel injection is performed by the respective fuel injection valves 20 in one combustion cycle of the engine 10, respectively, a microcomputer of an ECU 40 sets a power supply voltage of the injector drive circuit on the basis of injection times of the respective fuel injection valves 20, and makes the injector drive circuit drive the respective fuel injection valves 20 by the set power supply voltage.SELECTED DRAWING: Figure 1
