Abstract: An ignition timing control apparatus for a spark ignition internal combustion engine for a vehicle having a manually operated transmission system. The apparatus includes an ignition control system for controlling ignition timing in such a manner that the timing is advanced when the engine speed drops due to engagement of the clutch of the transmission apparatus to begin the initial movement of the vehicle. The drop in the engine speed is sensed by detecting whether a second order difference value of the engine speed is lower than a reference value. This realizes quick control of the engine speed.

Abstract: The invention constitutes a supplement to patent application No. P 31 34 883 and to patent application No. P 32 08 088. It relates to the electronic switching-off of the correction circuitry in the event of a large dwell angle and simultaneously maximum correction value. This object is attained by comparing the speed-dependent output voltage of an induction sensor at a comparator to a reference voltage which is chosen so as to be exceeded by the output voltage of the induction sensor from a certain rotor speed on with an output pulse being released at the comparator. The capacitor at which the sawtooth-shaped signal is generated is discharged by means of this output pulse such that there will not be any further correction of the control signal.

Abstract: 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.

Abstract: A spark timing control apparatus controls the spark timing to retard or advance in accordance with the output signal from a knock sensor. An accelerating condition of the engine is determined depending on a particular knock occurence patterns including; whether the interval of knock occurences is larger or small, the total amount of retard angles is larger or small, or the frequency of knock occurences. When the accelerating condition is determined, the advancing rate of the spark timing is increased until a steady state of the engine operation is determined based on the output signal of the knock sensor.

Abstract: A magnet ignition device is provided with an angular position detecting device for producing a first angular signal with one polarity corresponding to an angular position of a given crankshaft of an engine and a second angular signal with the other polarity corresponding to an angular position of the crankshaft retarded by a given angle relative to the angular position where the first angular signal is generated. An ignition timing operation circuit is driven by the first angular signal. A signal representing advance angle information of the result of the operation by the operation circuit and the second angular signal are both applied to a switching element. In the circuit arrangement, only the second angular signal is used as an ignition signal in low rotational frequencies suffering from a great variation of the rotational frequency of the engine and, in high rotational frequencies higher than a given rotational frequency, only the advance angle signal is used as the ignition signal. With such an arrangement, an instability of the ignition timing due to a great variation of the rotational frequency in low rotational frequencies is prevented thereby to secure an accurate and stable ignition timing.

Abstract: A closed loop timing optimization control for an internal combustion engine closed about the instantaneous rotational velocity of the engine's crankshaft is disclosed herein. The optimization control computes from the instantaneous rotational velocity of the engine's crankshaft, a signal indicative of the angle at which the crankshaft has a maximum rotational velocity for the torque impulses imparted to the engine's crankshaft by the burning of an air/fuel mixture in each of the engine's combustion chambers and generates a timing correction signal for each of the engine's combustion chambers. The timing correction signals, applied to the engine timing control, modifies the time at which the ignition signal, injection signals or both are generated such that the rotational velocity of the engine's crankshaft has a maximum value at a predetermined angle for each torque impulse generated optimizing the conversion of the combustion energy to rotational torque.

Abstract: An ignition timing control system for retarding the spark of a spark plug wherein the ignition timing is regulated to be practically constant while the engine speed is within a low range, but wherein the ignition timing is retarded in proportion to an increase in engine speed as the engine speed increases over a given speed. The system is applicable to capacitive discharge ignition systems and includes a control circuit for triggering the capacitive discharge system as a function of engine speed. The control circuit includes a pick-up coil for generating a voltage having an amplitude proportional to engine speed, and for providing a trigger signal at the peak of the voltage waveform when the voltage waveform is below a preset value. When the voltage waveform exceeds this value, as determined by a limit circuit, the trigger signal is generated as the voltage waveform falls from its peak and reaches the preset value. A zener diode may be used to set the limit or preset value, and several embodiments of suitable control circuits are illustrated.
