摘要： To monitor the rotation of a disc with normal marks and a reference mark, respective pulses P are produced upon passage of the marks, a first stored value being increased at a steady rate during the spaces between pulses and decreased during the pulses themselves, and a second stored value being increased at a lower steady rate throughout a whole cycle, whereby a comparison of the two stored values at the end of the cycle depends upon the time between the pulses and thus serves to distinguish between the passage of a normal mark and the passage of a reference mark. The stored value may be the charge on a capacitor (C1, C2) or the content of a counter. The disc may be attached to the camshaft of the engine of a motor vehicle and the results of the comparison may be used to determine the point of ignition and the point of fuel injection.
摘要翻译：为了监视具有正常标记和参考标记的盘的旋转，在脉冲经过时产生相应的脉冲P.第一存储值在脉冲之间的间隔期间以稳定的速率增加并且在脉冲本身期间减小，并且第二存储值在整个循环中以较低的稳定速率增加，由此在循环结束时两个存储值的比较取决于脉冲之间的时间，并且因此用于区分正常标记的通过和通过参考标记。存储的值可以是电容器（C1，C2）上的电荷或计数器的内容。盘可以附接到机动车辆的发动机的凸轮轴，并且可以使用比较结果来确定点火点和燃料喷射点。

摘要： Disclosed are methods to determine the phase angle of a four stroke internal combustion engine with an odd number of cylinders and without a camshaft detector. According to said methods, recognition of phase angle occurs by emission of a first signal from a crankshaft angle sensor presenting a singularity whereby said signal is placed in relation to a second signal, which is for example a speed signal or an output signal of an inlet-manifold air-pressure sensor and the shape of the second signal is evaluated in the range of singularity of the first signal. As this signal shape is variable according to whether the crankshaft is in first or second revolution, the phase angle can be determined precisely.
摘要翻译：给出的方法用于确定用于四冲程内燃机的相位位置具有奇数个汽缸的，没有凸轮轴传感器，其中的相位位置是通过从曲柄角传感器的第一信号，其具有一个奇点输出的信号检测到第二信号，其中，例如，一个速度信号或进气歧管压力传感器的输出，被引用和所述第二信号的过程中，在第一信号的奇异性的区域评估。由于该波形是不同的，这取决于曲轴是否处于其第一或第二转速，相位位置可以明确地确定。
