Abstract: In an external-ignition combustion engine operating with compression of the fuel mixture and continuous injection into the suction duct fuel is measured off by a valve by means of a slider actuated by a suction-responsive plate against a return force provided by fuel pressure and subject to control in dependence on operating characteristics of the engine. A pressure-control valve may be subject to a spring bias which is varied by a surface cam in response to throttle position and to pressure downstream of the throttle in the suction duct. A further control in response to engine temperature may be provided.

Abstract: In a fuel injection nozzle, for varying the fuel quantities injected thereby, there is provided a movable throttle member which determines the flow passage section of a bypass or return channel provided in the fuel injection nozzle. The position and thus the throttling effect of the throttle member is determined by the axial distance between two threadedly interengaging components of the fuel injection nozzle.
