Title:
FUEL INJECTION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/221157
Kind Code:
A1
Abstract:
In order to improve combustion stability while suppressing HC and PN discharged from a combustion chamber, an ECU 150 which controls a fuel injection device 101 which is installed in a fuel chamber 107 of an internal combustion engine so as to be able to inject fuel in a direction that intersects the sliding direction of a piston obtains the pressure value of the fuel to be supplied to the fuel injection device 101, and performs a control for causing the fuel injection device 101 to inject the fuel at least two times during a compression stroke, and when the obtained pressure value of the fuel is low, controls the timing of at least any one of the fuel injections during the compression stroke so that the timing is faster than the timing of a fuel injection corresponding to when the pressure value of the fuel is high.
