    • To permit use of shaft position transducers which provide needle pulses at predetermined angular positions of the crankshaft of an engine, such as Wiegand-type, and still enable generation of a counted dwell time even under transient conditions, or under low-speed conditions, the output from the Wiegand transducer is connected to a logic circuit which, under normal operating conditions, by use of a counter counts a predetermined time interval after opening of a switch in series with the ignition coil to determine the dwell period or initiation of current flow for a subsequent ignition event by resetting the counter with a reverse polarity subsequent pulse, thereby passing, upon reset, a predetermined count state which, similar to the normal counting of the count state, initiates closing of the switch. Thus, even though the normal counting time has not yet been reached, the reset operation of the counter will trigger closing of the switch and hence sufficient current flow through the ignition coil to store the appropriate electromagnetic energy therein for a reliable spark at the spark plug.
    • 为了允许使用在诸如Wiegand型发动机的曲轴的预定角度位置处提供针脉冲的轴位置换能器,并且即使在瞬态条件下或者在低速条件下仍然能够产生计数停留时间, 来自韦根传感器的输出连接到逻辑电路,该逻辑电路在正常操作条件下通过使用计数器在与点火线圈串联的开关断开之后计数预定的时间间隔,以确定电流的停留时间或电流的开始 随后的点火事件通过用反极性后续脉冲复位计数器,从而在复位时通过预定的计数状态,其类似于计数状态的正常计数启动开关的闭合。 因此,即使尚未达到正常的计数时间,计数器的复位操作将触发开关的闭合,从而使足够的电流流过点火线圈以在其中存储适当的电磁能,以便在火花塞处产生可靠的火花 。

    • A monitoring resistor in series with the spark coil primary winding and the electronic interruptor switch provides a signal to an integrator for shifting the control thresholds of a threshold switch that controls the interruptor away from their quiescent values that are nearer the zero crossover of the timing voltage wave provided by an engine driven timing signal generator. The integrator output voltage remains constant during the time the interruptor switch is open. While current flows through the interruptor circuit, the integrator increases the control voltage until the primary winding current reaches a predetermined level and then decreases the control voltage until the timing wave recloses the interruptor. While the control voltage is being decreased, the coil current is allowed to rise to a limiting value and is then held constant by another circuit controlled by the monitoring resistor that slightly reduces the conductivity of the interruptor switch in its closed condition, but this occurs only while the engine is accelerating to the operating speed range. During this time the switch-on threshold for controlling the interruptor is raised towards the peak of the timing wave, but the switch-off threshold is clamped to its initial value. With further increase in engine speed, the net effect of the integrator operation changes sign and the switch-on threshold is lowered. As soon as the switch-on threshold goes below its initial value, the switch-off threshold is unclamped and is depressed along with the switch-on threshold towards the negative peak of the timing wave by the integrator action. The result is to keep the amount of energy stored in the spark coil at the time of primary circuit interruption constant over a wide range of speed.
    • 与火花线圈初级绕组和电子中断器开关串联的监测电阻器向积分器提供信号,以将控制该断路器的阈值开关的控制门限移离其偏离定时电压零交叉的静态值 由发动机驱动的定时信号发生器提供的波。 积分器输出电压在断路器开关断开期间保持恒定。 当电流流过中断电路时,积分器增加控制电压,直到初级绕组电流达到预定电平,然后减小控制电压,直到定时波重新闭合中断器。 当控制电压降低时,允许线圈电流上升到极限值,然后由监控电阻控制的另一个电路保持恒定,这样可以在闭合状态下稍微降低断路器开关的导通性,但这只会发生 而发动机正在加速到运行速度范围。 在此期间,用于控制中断器的接通阈值向着定时波的峰值升高,但关断阈值被钳位到其初始值。 随着发动机转速的进一步提高,积分器运行的净影响变化,降低了开启阈值。 一旦开启阈值低于其初始值,关闭阈值就被解除锁定,并且通过积分器动作将其与导通阈值一起压向定时波的负峰值。 结果是在主电路中断时保持在火花线圈中存储的能量的数量在宽的速度范围内是恒定的。

    • The voltage across a capacitor is changed in a first direction while the current in the primary winding of the ignition coil increases to a predetermined value less than the value required for ignition and is thereafter changed in a second direction until ignition takes place. The voltage across the capacitor is applied to the inverting input of a difference amplifier constituting a threshold stage controlling the initiation and termination of current flow through the ignition coil. The two changes are symmetrical when the engine speed remains constant. The residual voltage across the capacitor at the end of the second change is maintained until the start of the next subsequent first change, so that the time at which the threshold stage switches in, that is the time at which primary current starts to flow in the ignition coil changes as a function of the residual voltage in the capacitor.

    • Current flow to the ignition coil during low-speed operation of the engine, is controlled by an auxiliary control switch which is connected in shunt with the primary of the ignition coil. Serially connected with the primary is a main control switch which is controlled to close until current through the primary has reached a certain value, at which time the main switch opens and the shunt auxiliary switch is closed to permit continued inductive current flow through the coil and thus store ignition energy, the cycle repeating to maintain current flow through the primary at a level to store sufficient energy for the ignition spark which, at the ignition instant, effects opening of the shunt circuit by opening the auxiliary switch while also opening the circuit to the primary, thus providing a high-voltage pulse which provides for sparking of the spark plug. The sensor for current flow through the primary is preferably a resistor which, when the voltage drop thereacross exceeds a predetermined level, controls changeover of a transistor.

    • A dwell angle control has three counting devices for detecting acceleration. In a first UP/DOWN counter (17), the count in one direction takes place throughout the time the current in the primary circuit of an ignition coil (25) exceeds a current threshold value (I1). The count in the other direction is constant with respect to time. The counts on the first counter are taken over into a second UP/DOWN counter (11) in response to the input signal, the counting direction also being determined by the input signals. When the count in the second counter (11) reaches an adjustable trigger threshold value, the closure time is initiated, the actual ignition time being fixed by an edge of a sensed signal, or the edge of the signal from an ignition computer. The adjustable trigger threshold value is advantageously determined by a third UP/DOWN counter (12) which is set to a fixed value (X) by an edge of the sensed signal and whose counting direction is also determined by the sensed signals. A very good dynamic response is achieved by the detection of acceleration by three counters during different time periods. It is advantageous to switch from a decrease in closure angle to an increase in closure angle at an adjustable speed by switching the adjustable trigger threshold value to a very small value and switching the counter (11) to a continuous DOWN count. This allows a matching to variable ON/OFF ratios of the sensed signal.
    • 驻车角控制具有三个用于检测加速度的计数装置。 在第一UP / DOWN计数器(17)中,一个方向上的计数发生在点火线圈(25)的初级电路中的电流超过当前阈值(I1)的整个时间。 另一方向的计数在时间上是恒定的。 响应于输入信号,第一计数器的计数被接收到第二UP / DOWN计数器(11)中,计数方向也由输入信号确定。 当第二计数器(11)中的计数达到可调触发阈值时,启动关闭时间,实际点火时间由感测信号的边缘或来自点火计算机的信号的边缘固定。 可调触发阈值有利地由被检测信号的边缘设置为固定值(X)的第三UP / DOWN计数器(12)确定,并且其计数方向也由感测信号确定。 通过在不同时间段内通过三个计数器的加速度检测来实现非常好的动态响应。 通过将可调触发阈值切换到非常小的值并将计数器(11)切换到连续的下降计数,从而可以将闭合角度的减小切换到可调节速度下的关闭角度的增加。 这允许匹配感测信号的可变ON / OFF比。

    • An ingition system for internal combustion engines has dwell angle control apparatus for controlling the switching times of an electronic switch (21) in the primary circuit of an ignition coil (22) in dependence on the signals of a rotating sensor (10) or an ignition computer (11). Specifically, speed dependent counting values are periodically generated in a counting apparatus (13) each being counted down in a further counting apparatus (14) controlled by an edge of the sensed signal or a computed signal. Upon reaching a presettable triggering counting value, the electronic switch (21) is closed (start of dwell period). This triggering value is set by periodic up and down counting processes in a control counter (17) the upwards counting being constant with respect to time and the count-down process being determined by the length of time of current flow above a settable current value through the ignition coil (23). This allows the counting process of the speed dependent counting value to be triggered and the electronic switch to be opened (ignition time) by a single sensed signal edge per cycle.
