摘要:
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.
摘要:
A fuel quantity distributor for use in conjunction with multicylinder combustion engines, in which two concentric, radially adjacent metering elements have metering inlet channels. The metering elements are rotatable relative to one another, and the edges of the metering inlet channels intersect each other and open a variable cross-section. The ratio of wetted perimeter to the diameter of the inscribed circle from the idling position to at least the partial load position, is substantially constant when one-third of the maximum cross-section is opened. The ratio does not exceed 6.0 and is measured in the plane of the cross-section.
