    • A device for electronically controlling adjusting devices in an internal combustion engine in which the adjusting devices can be controlled, by comparing differentiated engine speed signals with predetermined threshold values in such a way that shuddering oscillations of the internal combustion engine are counteracted. The engine speed variable (n) is derived by means of a sensor (10) which provides a plurality of pulses per revolution of the engine crankshaft or camshaft. A first devider (14) devides the pulses from the sensor (10) by a fixed ratio. The output of the divider (14) is further divided in a divider arrangement which provides different divider ratios in dependence upon engine speed, the divider ratios being chosen so that measurement at engine speed is made over a complete combustion period of the engine, or a multiple thereof.
    • 一种用于电子控制内燃机中的调节装置的装置,其中通过将差动的发动机转速信号与预定的阈值进行比较,使内燃机的颤抖的振荡得到抵消。 发动机速度变量(n)通过传感器(10)得到,传感器(10)每转发动机曲轴或凸轮轴提供多个脉冲。 第一偏移器(14)将来自传感器(10)的脉冲以固定的比率偏移。 分压器(14)的输出进一步被划分成按照发动机转速提供不同的分压比的分压装置,选择分压比使发动机转速的测量是在发动机的完整燃烧时段进行的,或 的倍数。
