ABSTRACT:
The invention solves the problem of feeding spark ignition engines with fuel and obtaining high total efficiency of engines. The method is characterized by that for supply control the signals of pressures of the medium in determined sections of the suction pipe passage are used. The fuel medium is subject to ultrasonic vibration with the frequency of from 20 kHz up to 60 kHz. The atomized medium is treated with an air stream. The device is equipped with an ultrasonic unit /1/ provided with an ultrasonic transducer /21/ to atomize the medium, connected with the control system of the fuel medium supply before feeding the medium to cylinders. The ultrasonic unit /1/ is provided with at least one intermediate channel /16/ to feed the fuel medium, connected with at least two output channels /18/ leading to the radiant surface b /20/ of the waveguide /19/ The device provides for high production yield of the mixture.
