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 and fuel injector placement.
Claims12
A 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, wherein the at least one bore defines said upper inlet and said lower inlet of said throttle body assembly;
- a fuel component cover located on a first side of said throttle body and an electronic control unit cover located on a second side of said throttle body, wherein said first side is about 90 degrees from said second side;
- at least one fuel injector disposed at least partially within said throttle body, wherein said at least one fuel injector is parallel to a mounting base of said throttle body;
- at least one connecting fuel passage extending from a fuel inlet passage, comprising a cross-channel passageway and a vertical passageway at least partially disposed within said fuel component cover, wherein said vertical passageway is in fluid communication with said at least one fuel injector;
- a throttle shaft extending though the throttle body and at least one bore, wherein said throttle shaft is perpendicular to a horizontal direction between a first end and a second end of said at least one injector;
- and
- said at least one 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 a bore of said throttle body.
