System to sense a marker on a rotating body

To accurately determine the position of a marker on a rotating disk, for example coupled to the crankshaft of an automotive engine to determine the angular position thereof, an inductive transducer picks up the field generated by a permanent magnet located on the disk and, to compensate for amplitude variations in the output due to speed changes of the disk, and eliminate the effects of spurious side lobes generated by reversely positioned magnets, the amplitude of the output signal is normalized in an amplifier which includes a non-linear input circuit. The non-linear input circuit, preferably, is a diode-resistor network, in which the diode is forwardly poled, and a controlled current is supplied to the diode, the control being effected by the output of the amplifier in a feedback circuit, so that the output obtained from the amplifier will be uniform regardless of change in speed of the rotating body, and hence change in amplitude of the voltage induced in the inductive pick-up.

Dwell control for an I.C. engine spark ignition system

An internal combustion engine ignition control includes a variable reluctance pick-up with a winding providing signals to an integrator the output of which controls an ignition switching circuit. The ignition switching circuit includes a current limiter circuit which operates to limit the coil current at a maximum level until the instant of ignition. A capacitor is charged and discharged under the control of the current limiter circuit so that the voltage on it depends on the ratio of the time for which the current limiter circuit is in operation to the ignition cycle duration. An active clamping circuit operates to override the integrator under the control of this capacitor so as to apply a variable preconditioning bias to the output of the integrator which has the effect of varying the instant at which the coil current is switched on. Closed loop dwell control is thus provided in a simple and convenient manner.

Ignition distributor for internal combustion engine

Device for recognition of valve timing phases

Изобретение относится к устройству для распознавания фаз газораспределения в двигателе внутреннего сгорания. Технический результат заключается в возможности создания устройства для распознавания фаз газораспределения, которое позволяло бы осуществлять синхронизацию без использования датчика положения распределительного вала и без использования дополнительных деталей и элементов. Устройство для распознавания фаз газораспределения предназначено для двигателя внутреннего сгорания, имеющего коленчатый вал, угловое положение которого непрерывно определяется путем обработки поступающих от датчика положения коленчатого вала сигналов в блоке управления, который в зависимости от углового положения вала выдает командные импульсы на впрыскивание топлива и на зажигание. Для распознавания фазы газораспределения после пуска двигателя блок управления воздействует на впрыскивание и анализирует устанавливающиеся в результате этого воздействия изменения частоты вращения вала двигателя. При этом для заданных цилиндров отключается впрыскивание, в результате чего в них не происходит впрыскивания топлива, и выходной сигнал датчика положения коленчатого вала контролируется на появление ожидаемой в ответ на такое отключение впрыскивания реакции. Впрыскивание топлива отключается после установления факта пуска двигателя в том диапазоне, в котором частота вращения снижается, причем этот диапазон соответствует нисходящей ветви характеристики пускового выброса при перерегулировании. 5 з.п. ф-лы, 9 ил.
