ENGINE DEVICE
Document Type and Number:
Japanese Patent JP2022089479
Kind Code:
A
Abstract:
To discharge vaporized fuel even if a fuel pump sucks the vaporized fuel when fuel in a fuel tank is boiling, and suppress generation of vaporized fuel in the fuel pump caused by heat generation amount of the fuel pump.SOLUTION: In an engine device including an engine and a fuel supply device having a fuel pump supplying fuel in a fuel tank to a fuel flow passage connected to a fuel injection valve of the engine, when boiling of the fuel in the fuel tank is detected, target rotational frequency of the fuel pump is set within a range between lower limit rotational frequency enabling discharge of vaporized fuel when the fuel pump sucks the vaporized fuel and upper limit rotational frequency enabling suppression of generation of vaporized fuel in the fuel pump caused by heat generation amount of the fuel pump, to control the fuel pump.SELECTED DRAWING: Figure 6
