Summary:FIELD: mechanical engineering; fuel systems of internal combustion engines. SUBSTANCE: proposed nozzle has spray tip needle 2 loaded by locking spring 12, additional adjusting member made in form of hydraulic piston 9 placed in guide housing 8 and acting through spindle 11 onto spray tip needle as and when it exceeds preset value preliminary travel hp. End of spray tip needle is made in one plane with end of housing of spray tip 1. Values of preliminary travel ha and additional travel ha of spray tip needle are defined by relationship of dimensions of nozzle parts. EFFECT: facilitated operation of internal combustion engine, reduced specific fuel consumption, improved manufacturability of nozzle. 2 cl, 3 dwg
