摘要： A current regulator is proposed for use in an electronically controlled, continuously operating gasoline injection system, with the aid of which a control element can be supplied with different current values depending upon the operating states of the engine. In addition to a current regulating phase during active operation, it is possible with the proposed current regulator to reverse the direction of current flow in the control element for the sake of blocking the supply of fuel during overrunning. Towards this end a circuit apparatus links signals relating to rpm, throttle valve position and temperature. Furthermore two safety circuit arrangements are proposed for the current regulator, so that in case of a failure of important components there is no impairment of safety, and emergency operation is assured.

摘要： It is proposed for a fuel metering system that a final control element be triggered with a regulated direct-current signal having clock components dependent on operating characteristics of an internal combustion engine in order to influence a fuel metering means. A further proposal is that the acceleration enrichment be triggered during starting. In this manner the desired starting enrichment is obtained by way of the sum of the post-starting, warm-up and acceleration enrichment. The acceleration enrichment per se begins beyond a predetermined air flow gradient and then has a steady course up to a maximum value. This subject is disclosed in combination with a continuously operating injection system, in which a corresponding overall control signal is prepared in a control unit and delivered to an electrohydraulic final control element. This final control element, in the specialized example, influences the working pressure of the differential pressure valves associated directly with the continuously functioning injection valves.

摘要： An apparatus is proposed for regulating the idling rpm in an internal combustion engine. The apparatus has a PI regulator which has an insensitivity control circuit associated with it. Minimum and maximum value limiting circuits are furthermore provided, their thresholds being dependent on operating characteristics. Finally, a D element circuit cooperates with the PI regulator. The D element is subject to a threshold, and it comes into effect only when the rpm is dropping, its function being such as to steepen the I component of the PI regulator.
