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
An electronic fuel injection throttle body comprising a plurality of air intake passages, each of the plurality of air intake passages comprising a valve, the valve rotating about an axis defined by a shaft, a sleeve disposed within the air intake passage and comprising an inner surface that defines at least a portion of the air intake passage, a plurality of orifices extending through a wall of the sleeve, each of the plurality of orifices being angled downward and at an angle to a radial direction, a passage being defined at least in part by the sleeve and the plurality of orifices being fluidly connected to the passage, at least one fuel injector positioned to inject fuel into the passage, the at least one fuel injector being connected to a fuel rail, the fuel rail comprising a passage that extends in a first direction, and the first direction being normal to the axis of the valve shaft.
An electronic fuel injection throttle body comprising a top surface and a bottom surface, four intake passages extending between the top surface and the bottom surface, the four intake passages extending through a core body, a first fuel delivery component being mounted to a first side surface of the core body and a second fuel delivery component being mounted to a second side surface of the core body, at least two fuel injectors mounted between the core body and the first fuel delivery component and at least two fuel injectors mounted between the core body and the second fuel delivery component, the first fuel delivery component comprising a first passage and the first passage comprising a first axis, the second fuel delivery component comprising a second passage and the second passage comprising a second axis, the first axis and the second axis being parallel with each other, the first passage and the second passage being interconnected by a transfer passage that is defined within the core body.
