内燃機関の燃料噴射装置。 In a fuel injection system for an internal combustion engine, the injection pump consists of an in-line injection pump that increases the pressure of fuel in synchronization with engine rotation, and an injection nozzle that injects high-pressure fuel supplied from this injection pump through an injection pipe. A return hole is formed in the plunger barrel that is opened and closed by a common lead at the same time as the feed port as the plunger moves up and down, and a fuel return passage is provided that communicates with the connection end of the injection pipe on the injection nozzle side. 1. A fuel injection device for an internal combustion engine, characterized in that a pressure regulating valve for maintaining residual pressure in an injection pipe at a predetermined value is interposed therebetween.
