Title:
FUEL INJECTION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/029314
Kind Code:
A1
Abstract:
This fuel injection control device controls the supply amount of fuel to an internal combustion engine, and comprises: an intake air amount detection unit that is provided to an intake air passage of the internal combustion engine and acquires a detection value relating to an intake air amount of the internal combustion engine; a fuel injection valve that is provided to a supply path for fuel and injects fuel in a gaseous state; a pre-injection pressure acquisition unit that acquires pre-injection pressure, which is the pressure on the upstream side of the fuel injection valve of the supply path; a post-injection pressure acquisition unit that acquires post-injection pressure, which is the pressure in a space in which fuel is injected by the fuel injection valve; and a fuel control unit that, when the fuel injection valve is to inject fuel at sub-sonic speed, causes the fuel injection valve to inject fuel in an injection time that is longer than when the fuel injection valve injects fuel at sonic speed, on the basis of the detection value from the intake air detection unit, the pre-injection pressure, and the post injection-pressure.
