Abstract
An ultrasonic wave type fuel atomizing apparatus for an internal combustion engine provided in an intake passage of the internal combustion engine and atomizing the fuel injected from a fuel injection pump by the ultrasonic wave vibration includes an ultrasonic wave vibrator, an oscillation circuit for generating ultrasonic waves for driving the ultrasonic wave vibrator, and a high voltage generating coil for boosting the output of the oscillation circuit and for applying the driving output to the ultrasonic wave vibrator, and furthermore, a feedback circuit is included to detect a current flowing through the high voltage generating coil and to control an oscillation frequency of the oscillation circuit thereby to make the driving frequency follow the resonance point of the ultrasonic wave vibrator.
