Abstract
A fuel injection device adapted to control the amount of injection by the opening time and opening area of a gate which is disposed in a fuel feed passage and which is controlled in connection with the engine rpm and the amount of suction air. The fuel injection device is characterized in that a choke is disposed between the fuel distributing port of a fuel measuring and distributing mechanism and the valve of an automatic valve type fuel injector, whereby the rate of flow and hence the rise time of pressure pulses applied to the injection valve are controlled to provide an accurate amount of injection.
