Beschreibung
Zusammenfassung:	A locomotive diesel engine nozzle comprises a nozzle body and a spraying hole, a hole opening of the spraying hole inlet end of the nozzle is a gradual-shrinking hole, a hole opening of the spraying hole outlet end is a gradual-expanding hole, the round hole cross section of the juncture of the gradual-shrinking hole and the gradual-expanding hole is the juncture section with the minimum spraying hole diameter, the gradual-shrinking hole and the juncture section are in circular-arc transition, the gradual-expanding hole and the juncture section are in circular-arc transition, and therefore the spraying hole with the inlet end and the outlet end in trumpet shapes is formed; the hole opening diameter of the gradual-shrinking hole and the hole opening diameter of the gradual-expanding hole are the same, and the position of the spraying hole juncture section is located on the center point of the middle axis of the spraying hole or the position between the center point of the middle axis of the spraying hole and t
