    • An ignition timing control apparatus for an internal combustion engine comprises a pick-up incorporated in a distributor for detecting a crank angle, a circuit for producing a basic ignition timing indicating signal on the basis of the output signal from the pick-up, a knocking detection circuit for generating a knocking detection signal, a circuit responding to the knocking detection signal and the basic ignition timing indicating signal to generate an actual ignition command signal delayed by a predetermined crank angle from the basic ignition timing, and the control apparatus further includes a circuit responding to these three signals to inhibit the operation of the knocking detection circuit during a period beginning at a time point which precedes to the operation of an inlet valve and an exhaust valve of a cylinder another than the cylinder in concern and terminating at a time point at which a predetermined time has elapsed since the ignition of the cylinder in concern.

    • In response to a predetermined engine crankshaft position a reference pulse is generated having a leading edge advanced with respect to that predetermined position as a function of the rotational speed of the crankshaft. At low engine speeds the reference pulse is directly used as the ignition current. A start-of-dwell-time data word is derived in response to the trailing edge of the reference pulse and an end-of-dwell-time data word is derived in response to the leading edge of a subsequent reference pulse. These data words are used for engine operations at constant high speeds to advance the beginning and end of the dwell time of ignition current by an amount commensurate with an increase in engine speed. When the engine is rapidly accelerated the dwell time is started in response to the leading edge of the reference pulse and terminated when the end-of-dwell-time data word is decremented to zero.
    • 响应于预定的发动机曲轴位置,产生参考脉冲,其具有作为曲轴的转速的函数的相对于该预定位置前进的前缘。 在低发动机转速下,参考脉冲直接用作点火电流。 响应于参考脉冲的后沿导出停留起始时间数据字,并且响应于后续参考脉冲的前沿导出停留时间数据字。 这些数据字用于以恒定的高速度进行发动机操作,以使起动电流的停留时间的开始和结束以与发动机转速的增加相称的量来推动。 当发动机快速加速时,响应于参考脉冲的前沿开始停留时间,并且当停留时间数据字减小到零时终止。
