摘要： A fuel injection nozzle assembly for use in an externally ignited internal combustion engine of the air/fuel mixture-compressing type and with fuel injection into a tube through which air is suctioned into the engine, comprising a fuel injection nozzle and heat-insulating means surrounding a part of the nozzle is described. The heat-insulating means surround especially the nozzle part to be inserted into a bore in the wall of the air intake tube. Preferably, the heat-insulating means is a sleeve member made of heat-insulating rubber. The assembly is such that the fuel injection nozzle can be readily removed from the air intake tube. Moreover, both the fuel injection nozzle and the sleeve member can be assembled as a unit.

摘要： 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.

摘要： A fuel injection system for substantially continuous injection into a suction tube of a mixture-compressing, spark plug-ignited internal combustion engine includes a fuel line and a fuel pump. A measuring member and an arbitrarily actuatable throttle flap are disposed, one behind the other, in the suction tube. The measuring member is displaceable in proportion to air quantity and against a resetting force which is normally constant but which is changeable in dependence on engine parameters. A metering valve having a movable part is disposed in the fuel line and coupled to the measuring member. The measuring member actuates the movable part for metering fuel quantity in desired proportion with respect to air quantity. A regulating mechanism, which includes a piston, is actuated in dependence on fuel pressure prevailing downstream from the fuel pump. The piston acts against the force of a spring.
