Abstract
Present embodiments provide an electronic fuel injection 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 bores or barrels of the throttle body may comprise one or more stackable fuel injectors. The fuel component cover may include a regulator with a housing for integrally with the fuel component cover or alternatively, a regulator may be located remotely.
Claims18
A throttle body assembly, comprising:
- a body having a first bore and a second bore extending downwardly on a side of a body centerline;
- a fuel component cover having an inlet, said inlet disposed at an angle to a horizontal;
- said body having at least a first fuel injector port formed at each of said bores;
- said body having at least a second fuel injector port cast at each of said bores and configured for machining to render a retaining area usable;
- said fuel component cover disposed over said first fuel injector port and said second fuel injector port;
- a valve plate disposed within each of said bores, said valve plates disposed on a throttle shaft;
- and,
- said first and second fuel injectors having an alignment direction which is substantially perpendicular to said throttle shaft.
A throttle body assembly, comprising:
- a body having a first bore and a second bore extending downwardly on a side of a body centerline;
- at least one first fuel injector port formed in each of said bores;
- at least one second fuel injector port formed in each of said bores;
- a fuel component cover having an inlet passage in flow communication;
- a vertical passage allowing flow communication to a second passage, said second passage capable of providing fuel flow to said second fuel injector port when configured for use;
- a valve plate disposed in each bore;
- and,
- a throttle shaft extending through said body and engaging said valve plates, said throttle shaft extending in a direction which is substantially perpendicular to a fuel injector horizontal direction.
