Device for atomizing the fuel for an internal-combustion engine

A device for atomizing the fuel for an internal combustion engine comprising:

• a fuel pump,
• an electromagnetic fuel-injection valve connected to said fuel pump,
• an air-injection port adjoining the injection port of said electro-magnetic fuel-injection valve,
• an electromagnetic air flow-controlling valve connected to said air-injection port, and
• an air pump for feeding air to said air flow-controlling valve,
• wherein said air flow-controlling valve is controlled in such a manner that the injection of air form said air-injection port takes place simultaneously with the injection of fuel from said fuel-injection valve,
• means for detecting the amount of air taken in,
• a pressure-accumulating vessel located between said air pump and said air flow-controlling valve,
• a computer circuit for producing a signal corresponding to the amount of air taken in, and
• an electric motor control circuit responsive to the signal produced in said computer circuit for producing the signal for controlling the motor for driving said air pump, whereby the driving power of said air pump is controlled in accordance with the amount of air taken in, and
• wherein said internal-combustion engine further comprises a means for detecting the ratio of the time during which said electro-magnetic air flow-controlling valve is open to one revolution of the crank shaft of said internal-combustion engine, whereby the driving power of said air pump is controlled in accordance with said detected ratio.
