Abstract
An electronic fuel injection throttle body unit has a core body with two side components. The two side components each including a fuel delivery passage. Four air intake passages extending vertically through the throttle body. Valves are rotatable within the air intake passages. The valves being connected to valve shafts that rotate about respective valve shaft axes. The valve shaft axes and the fuel delivery passages are perpendicular to each other.
Claims20
A bolt-on electronic fuel injection throttle body unit designed to fit single and dual carburetor manifolds, the throttle body unit comprising a core body, the core body comprising a left side and a right side,
- a left fuel delivery component being connected to the left side of the core body and a right fuel delivery component being connected to the right side of the core body, a left integrated fuel passage formed in the left fuel delivery component, a right integrated fuel passage formed in the right fuel delivery component, at least one axial end of the left integrated fuel passage receiving a plug or a port, at least one axial end of the right integrated fuel passage receiving a plug or a port,
- at least one left fuel injector in fluid communication with the left integrated fuel passage, the at least one left fuel injector being positioned at least partially vertically lower than the left integrated fuel passage, at least one right fuel injector in fluid communication with the right integrated fuel passage, the at least one right fuel injector being positioned at least partially vertically lower than the right integrated fuel passage,
- an electronic control unit being mounted to a side of the core body other than the left side and the right side, and
- a throttle linkage connected to the core body, the throttle linkage being positioned on one of the left side and the right side, the throttle linkage comprising a primary linkage crank, the primary linkage crank being coupled for rotation with a primary shaft, the primary shaft being supported for rotation relative to a passage in the core body, at least one valve being secured to the primary shaft such that the at least one valve rotates with the primary shaft.
An electronic fuel injection throttle body unit, the throttle body unit comprising:
- a core body having at least a first side and a second side;
- a first fuel delivery component connected to the first side of the core body and having a first integrated fuel passage formed therein;
- a second fuel delivery component connected to the second side of the core body and having a second integrated fuel passage formed therein;
- a first fuel injector in fluid communication with the first integrated fuel passage;
- second fuel injector in fluid communication with the second integrated fuel passage;
- an electronic control unit being mounted to a side of the core body other than the first side and the second side,
- a primary shaft supported for rotation about a first axis and secured to at least one valve disposed within a passage in the core body;
- and
- a throttle linkage positioned on one of the first side and the second side of the core body and coupled for rotation with the primary shaft.
An electronic fuel injection throttle body unit, the throttle body unit comprising:
- a core body having at least first side, a second side;
- a first passage including a first fuel delivery pathway;
- a second passage including a second fuel delivery pathway;
- a first fuel delivery component on the first side of the core body and comprising a first integrated fuel passage;
- a second fuel delivery component on the second side of the core body and comprising a second integrated fuel passage;
- a first fuel injector in fluid communication with the first integrated fuel passage and the first fuel delivery pathway;
- second fuel injector in fluid communication with the second integrated fuel passage and the second fuel delivery pathway;
- a primary shaft extending along a first axis and coupled to at least a first valve disposed within the first passage and a second valve disposed within the second passage;
- and
- a throttle linkage positioned on one of the first side and the second side of the core body and coupled for rotation with the primary shaft.
