FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: invention relates to nozzles delivering fuel into cylinder of internal combustion engine. Proposed electrohydraulically controlled nozzle contains spray tip with seat, body with fuel feed channels. One of channels is connected with spray tip space. Other channel is connected through jet with space accommodating plunger with fuel drain channel loading needle through spindle together with spring. Nozzle contains also electromagnet with armature in drain space, also loaded by spring. Spindle and plunger are made separate. Spindle is provided with travel limiter, and spring is installed under plunger. ^ EFFECT: reduced cyclic irregularity of fuel delivery into cylinder. ^ 1 dwg |
