FUEL SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/209148
Kind Code:
A1
Abstract:
A fuel supply device comprising: a fuel pump; fuel piping; a check valve; a first fuel supply mechanism which is connected to the fuel piping on the downstream side of the check valve and which supplies fuel to an internal combustion engine; a second fuel supply mechanism which is connected to the fuel piping on the downstream side of the check valve and which supplies fuel to the internal combustion engine with a higher pressure than the first fuel supply mechanism; a pressure regulating mechanism which adjusts the pressure of the fuel in the fuel piping; and a control device. The control device is configured to be switchable between a first mode of using the first fuel supply mechanism to supply the fuel and a second mode of using the second fuel supply mechanism to supply the fuel. In a case where switching information indicating that the second mode is to be switched to the first mode to supply the fuel has been detected, the control device switches the second mode to the first mode after a waiting time set in advance has elapsed since the detection of the switching information.
