Title:
FUEL INJECTION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2021156263
Kind Code:
A
Abstract:
To provide a fuel injection device for an internal combustion engine capable of suppressing environmental load in the internal combustion engine operated by selectively using liquid fuel and gas fuel.SOLUTION: A vehicle includes: an engine 2 that can be operated by switching liquid fuel and gas fuel; and an ECU 3 correcting fuel injection amount of the engine 2 through feedback control and switching fuel to be supplied to the engine 2 from the liquid fuel to the gas fuel when determining that correction amount through the feedback control has been stabilized after elapse of predetermined time from start of the engine 2. When fluctuation width of the correction amount of the fuel injection amount of the gas fuel through the feedback control is continued within a predetermined range for a predetermined time, the ECU 3 allows switching of the fuel to be supplied to the engine 2 from the liquid fuel to the gas fuel.SELECTED DRAWING: Figure 1
