Abstract
A fuel injection fuel supply system for a combustion engine has a fuel injector valve effective for metering and injecting all of the required fuel to the engine induction system; in one version a single valve functions to supply the required fuel in equal amounts to each of the combustion cylinders of the engine through chamber means exposed to superatmospheric air; an electromagnetic assembly having a magnetic open loop is used for cyclically opening and closing the injector valve.
