1. A fuel feeding apparatus comprising:
- (a) an intake passage feeding air to an internal combustion engine;
(b) fuel feeding means disposed midway of said intake passage;
(c) vibrating means disposed in said intake passage at a position of impingement of fuel fed from a fuel feeding part of said fuel feeding means;
(d) vibration generating means having said vibrating means fixed thereto and converting electrical oscillation into mechanical vibration; and
(e) electrical oscillation generating means for periodically changing the frequency of said electrical oscillation at a predetermined time interval and applying the same to said vibration generating means.

Abstract
In a fuel feeding apparatus of the type in which a vibrating element is vibrated by an electro-mechanical transducer converting electrical oscillation into mechanical vibration, and fuel injected from a fuel feeding part is directed to impinge against and atomized by the vibrating element, the frequency of the electrical oscillation applied to the transducer is changed at a predetermined period to promote atomization of fuel.
