摘要： A distributor for an internal combustion engine includes an ignition timing reluctor provided on a centrifugal spark advance member, ignition timing signal generating means for generating an ignition timing signal by detecting approach and passage of the ignition timing reluctor, a cylinder discriminating reluctor provided on the centrifugal spark advance member, and a cylinder discriminating sensor for generating a cylinder discriminating signal by detecting approach and passage of the cylinder discriminating reluctor. The distributor has a structure for compensating for any imbalance of its rotator. The cylinder discriminating signal is centrifugally advanced in the same way as the ignition timing signal, so that it is possible to reduce the width of the cylinder discriminating signal.

摘要： A method of and apparatus for generating a cylinder discriminating signal in a distributor for an internal combustion engine are disclosed. The cylinder discriminating signal is generated by a combination of a cylinder discriminating reluctor installed on a centrifugal spark advance member and a cylinder discriminating sensor attached to a vacuum spark advance plate to detect approach and passage of the cylinder discriminating reluctor. The width of the cylinder discriminating reluctor in the direction of rotation is set so as to correspond to an angle smaller than the entire range of spark advance of the ignition timing signal. The cylinder discriminating signal is advanced by both centrifugal spark advance and vacuum spark advance so as to overlap the ignition timing signal despite having a relatively narrow width. Since the width of the cylinder discriminating signal is reduced, it is possible to improve the control tolerances of the associated microcomputer.
摘要翻译：公开了一种用于在内燃机的分配器中产生气缸识别信号的方法和装置。气缸鉴别信号是通过安装在离心式火花提前部件上的圆筒鉴别反射器与安装在真空火花提前板上的气缸识别传感器的组合产生的，以检测气缸识别反射器的接近和通过。气缸判别偏振器在旋转方向上的宽度被设定为对应于小于点火正时信号的整个火花提前范围的角度。即使具有相对较窄的宽度，气缸识别信号也通过离心式火花提前和真空火花提前进行提升，从而与点火定时信号重叠。由于气缸识别信号的宽度减小，所以可以提高相关微型计算机的控制公差。
