Abstract
Present embodiments provide a throttle body which may be used with a variety of engines of different manufacturers. The throttle body includes an inlet which expands to two or more bores, which extend downwardly through the throttle body. The throttle body may provide improved fuel pathways and fuel injector placement.
Claims16
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;
- said upper inlet having a single cavity which opens in an expanding direction into two bores extending through said throttle body;
- said bores together defining said lower outlet;
- 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;
- a first fuel injector and a second fuel injector disposed at least partially within said throttle body, wherein said first and second fuel injectors are parallel to a mounting base of said throttle body;
- said fuel component cover connected to said throttle body and having at least one fuel passage in fluid communication with said first and second fuel injectors;
- said fuel passage extending from a fuel inlet of said fuel component cover, said fuel passage extending parallel to said expanding direction;
- a throttle shaft extending through said first and second bores of said throttle body, wherein said throttle shaft is perpendicular to a horizontal direction between a first end and a second end of each of said first and second fuel injectors, said throttle shaft extending in said expanding direction;
- and
- said first and second fuel injectors directing fuel into a channel of respective fuel distribution rings, each of said fuel distribution rings having a plurality of fuel apertures directing fuel into each of said bores of said throttle body.
7 more elements
A method of delivering fuel and air to a combustion engine manifold, comprising:
- pumping fuel to an inlet of an electronic fuel injection throttle body, said inlet expanding into a first bore and a second bore that extend through said electronic fuel injection throttle body to an outlet;
- moving said fuel through a fuel component cover through a fuel passage in communication with first and second fuel injectors;
- injecting fuel through said first and second fuel injectors into respective first and second bores;
- directing airflow through a single inlet of the said throttle body, wherein said expands into said first bore and said second bore;
- directing airflow through said first and second bores in flow communication with said single inlet;
- and,
- mixing said airflow and said fuel within said first and second bores.
