摘要： A control circuit for a fuel-injected internal combustion engine provides a substitute program for generation of fuel injection control pulses during engine starts at low temperatures. The substitute injection control pulses are made dependent on the ambient or engine temperature in the sense that, the lower the temperature, the greater is the length of the injection pulses, i.e., the larger is the quantity of initially injected fuel. The length of the injection pulses also depends on the elapsed duration of the engine starting attempt in the sense of gradually reducing the injected fuel quantity as the unsuccessful engine cranking proceeds. A fully opened throttle during engine cranking signals a flooded engine condition and completely interrupts fuel injection.

摘要： A method of and a device for regulating air-fuel ratio of an internal combustion engine includes an oxygen or lambda probe and a signal processing unit connected to the lambda probe. The change-overs of the lambda signal at the output of the lambda probe are compared with a succession of adjustable first time intervals t.sub.1 and, when no change-over is detected during the first time interval, the output signal from the signal processing unit which controls the air-fuel ratio is abruptly changed in a jump. To avoid overshoot of the output control signal, there is provided a resetting unit by means of which the jump of the control signal is reversed when the change-over of the lambda signal occurs in an additional monitoring time interval t.sub.2 following the first monitoring time interval t.sub.1.

摘要： A method and an apparatus for generating fuel metering control pulse which may be used to control the operation of injection systems, carburetors, or any other controllable fuel metering mechanism. The system includes two signal generators one of which continually generates a signal related to engine conditions while the other is engaged in deriving therefrom a fuel metering control pulse of appropriate length. The duration of the pulses may be obtained by the charging and discharging constant of control capacitors or by a process of numerical countdown of digital data.

摘要： The maximum speed of an internal combustion engine is limited by a device which compares the period of rpm-synchronous pulses with the time constant of a reference multivibrator. If the engine rpm is so high that a pulse terminates prior to expiration of the reference time period, a gate is activated and acts through further multivibrator circuits to interrupt the fuel delivery to the engine, e.g., the fuel injection control pulses are suppressed. If the maximum rpm is exceeded only intermittently, the device restores normal fuel injection control pulses after a predetermined number of pulses has been suppressed. If the maximum rpm is exceeded continuously, the device restores normal fuel control somewhat later than the time at which the engine speed drops to below maximum rpm.

摘要： A regulating device is described for regulating or adjusting the composition of the operating mixture of an internal combustion engine. When the engine or exhaust gas probe is still cold, the composition of the fuel-air mixture is controlled in an open-loop manner, and upon the attainment of a minimum operating temperature, the closed-loop regulating device for influencing the fuel-air mixture is activated. The activation of the regulating device is effected, when the engine is being operated under a load, after the attainment of a first, low temperature value; during engine idling, this is effected after the attainment of a second, higher temperature value. Via the throttle valve, a switchover is effected between two threshold values of a threshold switch.

摘要： The cyclic control pulses for actuating the fuel injection valves of an internal combustion engine are extended during engine starting at low temperatures. The degree of pulse extension, i.e. of fuel enrichment, is made dependent on engine temperature and decreases as a function of cranking time. In addition, a repeated starting attempt will be accompanied by reduced pulse extension to prevent excessive enrichment of the mixture. The pulse extension may also be retained for a period of time after engine cranking to insure smooth running.
