Title:
ELECTRONIC CONTROL FUEL INJECTION DEVICE
Document Type and Number:
Japanese Patent JP2023004462
Kind Code:
A
Abstract:
To provide an electronic control fuel injection device capable of reducing the number of components and simplifying a structure to reduce costs, and capable of promoting discharge of vapor generated in a pressurization chamber.SOLUTION: A passage for fuel flowing from a fuel intake pipe 4 to a pressurization chamber 5 and a return passage 9, which is a passage for discharging vapor generated in the pressurization chamber 5, are used in common, and the position of a plunger 2, which makes a predetermined reciprocating motion from a standby position, is set to a position where fuel supply and vapor discharge are possible, to eliminate an inlet check valve, so that it is possible to promote the discharge of vapor generated when fuel is supplied from the fuel intake pipe 4 to the pressurization chamber 5.SELECTED DRAWING: Figure 1
