Abstract
A dodge plunger, a nozzle spring, and a needle valve are received in a main body of a fuel injection nozzle in this order forwardly. The first fuel passage and the second fuel passage are formed in the main body. A distal end of the first fuel passage faces the needle valve, and a basal end thereof is open to a basal end face of the main body. A distal end of the second fuel passage faces the dodge plunger, and a basal end thereof is open to the basal end face of the main body. The basal ends of the first and second fuel passages are away from and independent of each other on the basal end face of the main body. A plug is attached to the basal end of the main body. A third fuel passage is formed in this plug. A distal end of the third fuel passage is in communication with the basal ends of the first and second fuel passages. The basal ends of the first and second fuel passages are in communication with each other only through the distal end of the third fuel passage.
