Fuel injection nozzle, supersonic - -.

摘要

An ultrasonic fuel injection nozzle comprises a generator for generating ultrasonic vibrations, a vibrator secured to the ultrasonic vibration generator and a valve for supplying fuel to the vibrator. The vibrator is secured to the ultrasonic vibration generator at one end and is formed with a cavity in its other end portion for atomizing fuel therein. The vibrator has a fuel passage communicating with the interior of the cavity. A valve is provided for normally closing the passage and for opening the passage to discharge an amount of fuel depending upon the passage opening duration. A fuel atomizing portion serves to reduce the discharged fuel to minute particles through the effect of ultrasonic vibrations.
