するアルコール燃料噴射ポンプの注油機構。 In an alcohol fuel injection pump that discharges fuel by reciprocating a plunger within a barrel and controls the amount of fuel discharged by changing the rotational position of the plunger around its axis, the plunger has an opening on the surface of the lead part. An oil hole that opens on the outer periphery on the proximal side of the lead part, and an oil passage that communicates the oil hole with the oil hole are provided on the barrel side. an oil supply hole extending through the fuel supply hole, and the relative positions of the opening of the oil hole and the inner opening of the oil supply hole are arranged such that the two can communicate only when the plunger is located at a position where fuel can be discharged. A lubrication mechanism for an alcohol fuel injection pump, characterized in that an outer opening of the lubrication hole is connected to a supply source of lubricant or the like.
