ABSTRACT:
In a fuel injection pump for use in an internal combustion engine, an injection timing control system actuatable in response to a pressure varying in dependence on engine r.p.m., which is designed to convert acceleration of a fuel injection quantity setting movable operating member into an electrical signal to obtain a control signal based upon said electrical signal for driving a magnet valve for controlling said pressure, thereby varying the injection timing by a proper amount in immediate response to an engine accelerating operation.
