Title:
燃料噴射制御装置
Document Type and Number:
Japanese Patent JP6945356
Kind Code:
B2
Abstract:
Combustion stability can be improved while HC and PN discharged from a combustion chamber are prevented. In an ECU that controls a fuel injection device installed in a combustion chamber of an internal-combustion engine so as to be able to inject fuel in a direction intersecting with a sliding direction of a piston, a pressure value of the fuel supplied to the fuel injection device is acquired, control is performed such that the fuel injection device injects the fuel at least twice in a compression stroke, and control is performed such that fuel injection timing of at least one time in the compression stroke is advanced earlier than fuel injection timing of a time corresponding to the high pressure value of the fuel when the acquired fuel pressure value is low.
