    • An input-output unit carries out some of the operations previously carried out in the microcomputer controlling the ignition, injection, etc. processes so that the number of bits in the microprocessor can be reduced. The input-output unit includes a counter which furnishes speed-dependent or angle-dependent signals. During a predetermined angle of rotation or while a particular speed-dependent value is counted and down, a frequency proportional to the quantity of air in the air inlet is counted, the resultant air number transferred to the microprocessor where it is modified. The modified air number can be counted down in the same counter which was used to count down the speed-dependent signals. The time required for counting down the modified air number determines the injection time and/or the closing time for an electronic switch in the primary circuit of the ignition coil. When the angle-dependent signal is used, a further counter counts down the air number several times, each time generating an interrupt signal. The latter count is in the microprocessor and when a predetermined number has been received, the microprocessor furnishes a terminate signal ending the controlled process.
    • 输入输出单元执行先前在微型计算机中进行的一些控制点火,喷射等处理的操作,使得可以减少微处理器中的位数。 输入 - 输出单元包括提供速度相关或取决于角度的信号的计数器。 在预定的旋转角度或者在特定的速度相关值被计数和下降时,计数与空气入口中的空气量成比例的频率,将合成的空气编号转移到微处理器进行修改。 修改后的空气数量可以在用于对速度依赖信号进行倒计数的同一个计数器中倒计时。 倒数改变的空气数量所需的时间决定点火线圈的初级回路中的电子开关的注入时间和/或关闭时间。 当使用与角度相关的信号时,每当产生中断信号时,另外一个计数器会对空气数进行多次倒数。 后一个计数在微处理器中,并且当已经接收到预定数量时,微处理器提供结束被控制过程的终止信号。

    • The destination of commands provided by a microcomputer to an input-output unit over a data bus is provided without an address bus, while a control circuit in the input-output unit is connected with the microcomputer by connections for only three binary signals in one direction, "clear", chip-select and data strobe and one in the other, namely interrupt. The control circuit has a decoder connected to the data bus that sorts out the commands, feeding the outputs through a gate array that are enabled by the chip-select and data strobe signals for timing. Commands for switching, such as beginning and ending counts, and so on are one-byte commands directly transmitted to the appropriate circuits of the input-output. Read and write commands are two-byte commands sequenced by a sequencing and lockout circuit, the circuit selected in first byte being activated to read or write to or from the data bus in the second byte while the decoder is blocked. The direction of transmission of the data bus is controlled over a single connection from the control circuit in accordance with whether a write command is or is not present.

    • A central digital memory contains data relating values of operational variables of an installation to values of a stored parameter. The central memory is addressed in parallel via input lines carrying the address of the stored data. The address is generated by selecting one of several discrete input lines leading to an address selector memory which contains preliminary addresses related to the various operational states of the installation. A portion of the preliminary address is delivered directly to the central memory whereas another portion is used to preset a counter. If the particular operational state is dependent on another parameter, for example temperature, a temperature-dependent clocking frequency is admitted to the counter and alters its contents which are then used to supplement the first portion of the address already delivered to the central memory. If no temperature dependency exists, the second portion of the address is passed on without change.
    • 中央数字存储器包含将安装的操作变量的值与存储的参数的值相关联的数据。 中央存储器通过承载存储数据地址的输入线路并行寻址。 通过选择通向地址选择器存储器的几个离散输入线之一来产生地址,该地址选择器存储器包含与安装的各种操作状态相关的初步地址。 初步地址的一部分直接传送到中央存储器,而另一部分用于预设计数器。 如果特定操作状态取决于另一参数(例如温度),则温度相关的时钟频率被允许进入计数器并改变其内容,然后将其内容用于补充已经传送到中央存储器的地址的第一部分。 如果不存在温度依赖性,则地址​​的第二部分被传递而不改变。

    • A distributorless ignition system using a dual-spark ignition coil generates a signal indicative of which of the two cylinders associated with the dual-spark coil is operating in its power stroke by means of a single detector connected to a predetermined one of the cylinders. The output of the detector is fed to a sample and hold circuit which supplies the peak value from the detector to the control unit of the ignition system where the peak value is evaluated and identified by comparison to a previously obtained peak value. The control unit indicates that the predetermined cylinder is in its power stroke when the detected peak value signal is at its higher level. Conversely, when the peak value signal is at its lower level the control unit determines that it is the other of the two cylinders which is in its lower stroke and signals this accordingly.
