    Abstract: A fuel-metering unit adapted for use in an internal combustion engine having an exhaust pipe is described which unit comprises an air-intake suction tube, a randomly adjustable throttle valve therein, an air-measuring device mounted in the suction tube upstream of the throttle valve, by-pass means connected with the suction tube and bypassing the air-measuring device and means for metering fuel in amounts substantially proportional to the amount of air flowing through the suction tube. This unit is improved by providing control valve means associated with the by-pass means and adapted for controlling the by-pass means and thereby varying the proportionality of fuel and air in dependence on characteristic engine data, and by providing an exhaust gasmeasuring probe adapted for mounting in the exhaust pipe of the engine and adapted for controlling the control valve means.

    Abstract: In a fuel distributor - in which the fuel to be delivered to a cylinder of an internal combustion engine is dosed by a metering valve - in order to maintain at a constant value the difference between the fuel pressure upstream of and downstream of the metering valve, there is provided a plurality of control valves (one for each cylinder) having a flat seat whose flow passage section is directly variable by a movable membrane. One side of said membrane is exposed to the downstream fuel pressure urging said membrane into a control valve opening direction, the other side of said membrane is exposed to the upstream fuel pressure urging said membrane into a control valve closing direction.

    Abstract: An improved fuel injection system in an internal combustion engine is described, wherein the system has a discharge outlet for fuel to be injected and brought to a combustion space of the engine, an electrical heating element for heating the fuel directly upstream of the discharge outlet, a fuel entry structure for feeding fuel to the heating element and temperature control structure for controlling the heating by the heating element, at engine temperatures below the optimal operational engine temperature and as a function of engine temperatures influencing the formation of the fuel-air mixture in the combustion space, the fuel being heated to such a degree that the preponderant portion of the amount of fuel to be injected is converted to the gaseous phase not later than immediately after leaving the discharge outlet, and wherein the improvement comprises an internal space in the system, adapted for the flow of fuel therethrough and extending from the fuel entry structure to the discharge outlet, which space is laid out for the smallest fuel volume possible, but in any event has a volume smaller than the volume of fuel injectable during about eight work cycles of the engine while the latter is idling.

    Abstract: An apparatus for interruption of fuel supply in an internal combustion engine, during non-operation of the engine, includes a battery-operated fuel supply mechanism. The fuel supply mechanism operates independently of the engine. An ignition switch is operatively arranged to separate the fuel supply mechanism from the engine. An air-quantity measuring device is disposed within the suction tube of the internal combustion engine. The measuring device is operatively arranged to close an electrical contact when in its rest position. In that position and whenever the ignition switch is also closed, a current path is completed between the battery and a relay which is biased mechanically by a spring. Whenever the relay is not energized and the ignition switch is also closed, a current circuit is completed between the battery and the fuel supply mechanism to effect delivery of the fuel to the engine.

    Abstract: A fuel supply system for mixture-compressing, externally ignited internal combustion engines is disclosed in which the influence of variable atmospheric pressure on the fuel-air mixture is compensated for by providing a secondary spring having pretension which is changeable in dependence on atmospheric pressure, this spring being fixed to a bellows which responds to atmospheric pressure. A primary control spring, together with the secondary spring, acts on a membrane which is part of a second pressure control valve.
