Abstract
A fuel injection system for internal combustion engine of the spark ignition type is provided with a fuel metering apparatus including a fuel flow control orifice having an opening area or flow section which is varied in dependence upon a flow rate of intake air inducted into the engine. A fuel metered through the fuel metering apparatus is distributed by a distributing plate driven synchronously with the rate of revolutions of the engine at a predetermined rate and supplied intermittently and sequentially to individual cylinders of the engine through associated fuel injection valves by means of a pressure feeding apparatus such as plungers which are provided in number equal to that of the cylinder and driven synchronously with the revolution of the internal combustion engine.
