PURPOSE:To obtain a fuel gauge mechanism to be easily manufactured with high accuracy by constructing a gauging shaft to be turned according to the amount of sucked air out of the combination of two half parts for forming a variable orifice. CONSTITUTION:When the amount of sucked air running through a suction passage Im of an internal combustion engine is increased, a turning plate 14 is turned clockwise in the figure to turn a gauging shaft 13 to the increasing side. Subsequently, a slit 29 is shifted to accord with a fixed hole 31, and the opening area of a variable orifice Or is increased for increasing the amount of fuel supply to a fuel injection nozzle. Meanwhile, when the amount of sucked air running through the suction passage Im is reduced, the turning plate 14 is reversely turned to turn the gauging shaft 13 to the reducing side, and the slit 29 is separated from the fixed hole 31. Thus, the opening area of the variable orifice Or is reduced, and the amount of fuel to be injected into each cylinder can be reduced. |
