Abstract
Present embodiments provide a throttle body which may be used with a variety of engines of different manufacturers. The throttle body may be used to replace mechanical or hydraulically controlled carburetors with electronic fuel injection. The throttle body may provide improved fuel pathways through and about the throttle body in order to move fuel to opposed side. The throttle bodies may have improved configuration of the fuel injectors. Further, the throttle body may have computer mounted on the throttle body and a notch formed in the throttle body to define a wire routing pathway from the computer to the injectors.
Claims19
An electronic fuel injection throttle body assembly, comprising:
- a throttle body having an upper inlet and a lower outlet configured to mount to an internal combustion engine;
- at least one bore extending through said throttle body;
- a first fuel injector disposed at least partially within said throttle body at a first position;
- a second fuel injector disposed at least partially within said throttle body at a second position, said second position substantially vertically aligned with said first position;
- said first fuel injector and said second fuel injector directing fuel into a channel of at least one fuel distribution ring, said at least one fuel distribution ring having a plurality of fuel apertures directing fuel into said at least one bore of said throttle body;
- a throttle valve disposed within said bore and at a lower elevation than said fuel injectors toward said outlet side of said throttle body;
- and,
- a throttle lever assembly disposed on a side of said throttle body, a shaft extending from said throttle lever assembly toward said bore to control a position of said throttle valve.
An electronic fuel injection throttle body assembly, comprising:
- a throttle body having an upper inlet side and a lower outlet side, said throttle body configured to mount to an internal combustion engine;
- at least one bore extending through said throttle body;
- a fuel component cover located on a first side of said throttle body having:
- a lower fuel inlet passage,
- a connecting fuel passage extending upwardly from said fuel inlet passage to an upper fuel passage, said upper fuel passage delivering fuel to an external fuel conduit extending from said fuel component cover to at least one of a second side of said throttle body or a pressure regulator;
- an electronic control unit mounted to said throttle body and a cover mounted over said electronic control unit, said cover and said electronic control unit positioned on a side of said throttle body other than said first side and said second side.
An electronic fuel injection throttle body assembly, comprising:
- a throttle body having an upper inlet side and a lower outlet side, said throttle body configured to mount to an internal combustion engine;
- at least one bore extending through said throttle body;
- a fuel inlet passage located on one side of said throttle body, an external fuel conduit which passes fuel from said first fuel inlet on said one side, to a second fuel inlet passage on a second side, and to a fuel outlet on said second side;
- an electronic control unit mounted to said throttle body and a cover mounted over said electronic control unit, said cover and said electronic control unit mounted on a side of said throttle body other than said first side and said second side;
- a notched area of said throttle body defining a wire pathway from said electronic control unit to within a covered area having at least one fuel injector.
