Fuel supply system for fuel injection type engine

Abstract

Abstract PURPOSE: To promote atomization of the fuel by providing and opposing a fuel injection nozzle and an ultrasonic vibrating plate within a venturi of an intake manifold and further forming the venturi in a slit shape. CONSTITUTION: There are arranged a venturi portion 5 and a throttle valve 4 within an intake manifold 3 downstream of an air flow meter 9. The venturi portion 5 is provided with a fuel injection nozzle 6 which is controlled by a computer 8 based on a signal from the air flow meter 9. The venturi portion 5 further includes an ultrasonic vibrating plate 7 opposed to the nozzle 6, the plate 7 formed integrally with a seramic vibrater 10 driven by a high frequency oscillator 11. The venturi portion 5 is shaped in a slit form and the vibrating plate 7 is positioned in the longitudinal direction of the slit like venturi portion 5, thereby atomizing effectively all the fuel injected from the nozzle 6.
