Title:
FUEL INJECTION DEVICE
Document Type and Number:
Japanese Patent JP2017075607
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To cause early fusion of wax in a fuel filter.SOLUTION: A fuel injection device includes a leak fuel return flow path 20 for returning leak fuel returned from fuel injection means 5 to a fuel tank 1, a surplus fuel return flow path 23 for returning surplus fuel from a fuel supply pump 3 to the fuel tank 1, control means 6 for controlling the fuel supply pump 3 and the fuel injection means 5, a speed detector 6 for detecting an engine speed, and a torque detector 6 for detecting engine torque. The control means 6 performs first control to idling-drive a solenoid valve 60 of the fuel injection means 5 when the engine speed and the engine torque are within a first region, and performs second control to increase the pressure of fuel to be forcibly fed by the fuel supply pump 3 or performs third control to perform both the first control and the second control when the engine speed and the engine toque are within a second region lower than the first region.SELECTED DRAWING: Figure 1
