A multi-hole type fuel injection nozzle is disposed so as to be movable in the axial direction with its tip nozzle facing toward the combustion chamber of the engine, and the fuel injection nozzle includes a moving means for moving the nozzle in the axial direction. A variable protrusion device for a multi-hole fuel injection nozzle in a diesel engine equipped with a multi-hole fuel injection nozzle. (2) Utility model registration claim No. 1, wherein the moving means comprises a spring that biases the fuel injection nozzle in the forward direction, and an electromagnetic solenoid that moves the fuel injection nozzle backward against the elasticity of the spring when excited. A device for varying the protrusion amount of a multi-hole fuel injection nozzle in a diesel engine according to item 1). (3) The moving means comprises a spring that urges the fuel injection nozzle in the forward direction and a hydraulic circuit that uses hydraulic pressure to move the fuel injection nozzle backward against the elasticity of the spring.
A device for varying the protrusion amount of a multi-hole fuel injection nozzle in a diesel engine according to item (1).
