Abstract
A fuel injection pump for Diesel engines comprises a plunger unit in the pump body, a delivery valve, and an injection-quantity control mechanism in the pump body between the plunger unit and delivery valve. The control mechanism has a piston slidable in the pump body and communicated with the plunger unit and delivery valve and also has an injection-quantity control member coaxial with the piston and axially adjustable in position to press the piston against the pump body with the aid of a spring on the other end of the piston. The lift limit distance of the piston to be adjusted by the injection-quantity control member is preset to a range not less than that obtained by dividing the quantity of fuel to be injected at the engine start by the cross sectional area of the piston.
