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.
Claims12
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.
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.
