FIELD: electrohydraulic spraying of liquid; injection of fuel in internal combustion engines. SUBSTANCE: spark discharge is created in flow of liquid flowing constantly in direction perpendicular to axis of nozzle orifice. Spark discharge is created under action of high-voltage electric field whose intensity vector is directed in parallel with nozzle orifice. Spark discharge is created in flow of liquid flowing at a rate of no less than 5 m/s. Device for realization of this method has coaxial liquid supply passage 6 inside central electrode 5. Housing 1 is provided with additional branch pipe 4 for discharge of liquid. Central electrode is mounted in insulator 7 for axial motion. Nozzle orifice 2 is provided with cut-off valve 9. EFFECT: enhanced efficiency. 6 cl, 1 dwg
