Abstract

A throttle body fuel injection system including a throttle body with at least one air intake, a fuel injector coupled to the throttle body at a fuel port and an annular ring coupled to the cylindrical inner wall of the air intake. The annular ring includes a primary fuel discharge orifice adjacent to the fuel port and a plurality of secondary fuel discharge orifices arranged radially around the annular ring for spraying atomized fuel into the air intake.

Claims (27)

1. A fuel injection throttle body for a non-carbureted internal combustion engine, comprising:

an air intake extending through said fuel injection throttle body in a vertical orientation;

said air intake capable of allowing an airflow to move from an upper end to a lower end of said air intake;

a fuel port in said fuel injection throttle body and capable of receiving fuel from an electronic fuel injector;

a fuel channel in fluid communication with said fuel port to receive said fuel;

a plurality of orifices disposed annularly about said air intake allowing said fuel to pass from said fuel channel into said air intake;

a throttle plate disposed in said air intake and rotatable on a shaft, said throttle plate movable to vary the airflow moving through the air intake; and,

an electronic controller which controls said electronic fuel injector.

2. The fuel injection throttle body of claim 1 , said air intake comprising at least two air intakes.

3. The fuel injection throttle body of claim 1 , said air intake comprising four air intakes.

4. The fuel injection throttle body of claim 1 , said electronic controller disposed on a side of said fuel injection throttle body.

5. The fuel injection throttle body of claim 1 , said plurality of orifices comprising one or more sizes.

6. The fuel injection throttle body of claim 1 , further comprising a fuel ring disposed within said air intake, wherein said fuel channel is formed in said fuel injection throttle body, or said fuel ring, or both.

7. A fuel injection throttle body for a non-carbureted internal combustion engine, comprising:

a plurality of air intakes that extend between an upper end of said fuel injection throttle body and a lower end wherein airflow moves through from said upper end to said lower end;

each air intake of said plurality of air intakes having a fuel port disposed in said fuel injection throttle body, and capable of receiving fuel from an electronic fuel injector;

each said electronic fuel injector configured to be in fluid communication with a fuel supply;

a fuel channel disposed within each said air intake, said fuel channel receiving fuel from said electronic fuel injector;

a plurality of orifices disposed in an annular ring allowing said fuel to flow from said fuel channel into said air intake;

wherein said fuel passes through said plurality of orifices and mixes with said airflow moving between said upper end and said lower end;

a throttle shaft having a throttle plate thereon, said throttle plate rotatably disposed within said air intake; and,

an electronic control unit to control said fuel from each said electronic fuel injector.

8. The fuel injection throttle body of claim 7 , said plurality of air intakes comprising two air intakes.

9. The fuel injection throttle body of claim 7 , said plurality of air intakes comprising four air intakes.

10. The fuel injection throttle body of claim 7 , said plurality of orifices being one or more sizes.

11. The fuel injection throttle body of claim 7 further comprising each said annular ring disposed in one said air intake of said plurality of air intakes.

12. The fuel injection throttle body of claim 11 , said fuel channel formed in said fuel injection throttle body, or said annular ring, or both.
