Description

The invention relates to engine building, in particular to electrically controlled injectors and can be used to inject fuel into an internal combustion engine (ICE).

The aim of the invention is to improve the dispersion of fuel, as it occurs under the influence of ultrasonic vibrations of the transducer and an increase in the accuracy of dosing, since the magnitude of the cyclic supply is proportional to the number of ultrasonic pulses.

The drawing shows the proposed nozzle.

The nozzle contains: an ultrasonic transducer 1, at the ends of which electrodes 2 and 3 are applied. To the lower end

The ultrasonic transducer 1 is attached (for example, glued) to a quarter-wave cup 4, with which the ultrasonic transducer 1 is mounted to the R housing 5 using a nut 6 and sealed with gaskets 7 and 8. A hub 9 is attached to the bottom of the glass 4 from the bottom (for example, glued), the lower part of which the spool is located Yu. The lower part of the housing 5 is attached to a sprayer 11 having spray holes 12, a channel 13, and a pre-nozzle cavity 14 connected by a channel 13 with an intermediate cavity 15. The fitting 16 is designed for the fuel inlet into the intermediate cavity 15. The control unit 17 is connected to its control output by the electrodes 18 and 19c
