EFI throttle body with side fuel injectors

摘要

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.
