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.
