Abstract
What follows is a description of a fuel injection system for spark plug-ignited internal combustion engines with compression of the air-fuel mixture and structure for controlling the system pressure. The system is one which includes a device for regulating a fuel injection quantity operating in dependence on the air quantity streaming through a suction tube of the engine, a pressure regulator for determining normal system pressure, injection nozzles which have an opening pressure lower than the system pressure, a continuously delivering fuel pump, and the structure identified above. This structure adjusts the device for regulating the fuel injection quantity so that the starting pressure in the system is retained below the opening pressure of the injection nozzles and above the vapor pressure of the fuel until a quantity of fuel sufficient to replace the quantity of fuel evaporated or leaked due to a temperature gradient in the system resulting from engine cut off has been restored.
