摘要： 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.

摘要： To prevent generation of a spurious spark at the spark plug if the distributor braker control assembly should have commanded an ignition control transistor to be conductive and when the ignition switch is disconnected under those conditions, thus cutting off power to the ignition control transistor rendering it non-conductive and causing spurious voltage pulses which results in a spark at the ignition, a control path is provided connected to a control transistor for the actual ignition transistor and connected in circuit with the current flow due to the energy stored in the ignition coil to control the emitter-collector path of the ignition switching transistor to continue to remain conductive for a short period of time to drain off the stored energy in the coil, although the main ignition switch has been opened.

摘要： To prevent a spurious inductive spark when the master ignition switch of the vehicle is opened with the breaker terminals closed, so that current stored in the ignition coil might cause a spurious inductive voltage pulse, a protective circuit branch is connected in parallel across the primary of the ignition coil and includes an auxiliary semiconductor short-circuiting switch, preferably a thyristor, the conduction of which is controlled to close by an auxiliary control circuit which senses opening of the master ignition switch and permits application of a portion of the inductive current flow to the gate of the thyristor to render it conductive, thus short-circuiting the primary of the ignition coil and preventing an inductive voltage kick which might cause a spurious spark.

摘要： 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.

摘要： To provide for gradual turn-off of an ignition coil current control transistor, a control capacitor which provides turn-off current has its charge state changed gradually by means of an auxiliary transistor so connected to the capacitor that the conduction of the emitter-collector path of the auxiliary transistor is gradually changed, the main switching transistor being connected to and controlled by the auxiliary transistor and likewise changing gradually from conductive to blocking state in dependence on the gradual change in conduction of the emitter-collector path of the auxiliary transistor to prevent rapid turn-off of the main switching transistor and hence an undesired pulse at the secondary of the ignition coil which may induce continued operation of the internal combustion engine even though the ignition has been turned off.

摘要： A switching transistor (7, 9) is serially connected with the primary (5) of an ignition coil; current flow therethrough is controlled from an a-c signal generator (16) with respect to an ON threshold level (Ue) to store electromagnetic energy, and an OFF threshold level (Ua) to generate a spark; a variable conductivity circuit (26) controlled from a sensing resistor (8) modifies the response level of the threshold switch (13) with respect to the null or cross-over level of the applied signal. To prevent excessive current flow under idle-speed conditions, in accordance with the invention, the ON threshold level, at least, of the switch is shifted by introducing an auxiliary bias voltage derived from an auxiliary capacitor (36) and connected (37, 38) by the signal source through a diode (38) which prevents application of an auxiliary bias voltage to the threshold switch (13) under extremely low, e.g. starting conditions, permits application of the additional bias voltage providing for shift of the ON response level (Ue) under idling conditions, but again loses control as the speed continues to increase, and control by the variable conductivity circuit takes over.

摘要： A transistor switch connected in series with the primary winding of the ignition coil permits and blocks current flow through the coil when in a conductive and non-conductive state respectively. Normally, the switch is "on" and "off" respectively in the presence and absence of an ignition current pulse furnished in synchronism with the rotation of the crankshaft of the engine. For increasing speeds, the time the switch is "on" prior to the ignition time is increased by switching it to the conductive state when the charge on a control capacitor reaches a predetermined charge. The charge on the control capacitor is changed in a first direction following receipt of each ignition signal. The rate of change of charge depends upon the resistance of the emitter-collector circuit of a first control transistor. The latter is, in turn, determined by the charge on an integrator capacitor which varies with changes in engine speed. When the charge on the control capacitor reaches a predetermined charge, the output transistor switch to the conductive state allowing current flow in the ignition coil.

摘要： In a known ignition system, the emitter-collector circuit of the ignition transistor is connected in series with the primary winding of the ignition coil and with a precision resistor. When the voltage across the latter exceeds a predetermined value, an auxiliary transistor is switched to a conductive state. The emitter-collector circuit of the auxiliary transistor is connected to the base of the ignition transistor and, when conductive, prevents further increases of current through the primary winding of the ignition coil. To protect this circuit, a series circuit including two Zener diodes is connected between the base and collector of the ignition transistor. Further, a voltage divider is connected in parallel with the emitter-collector circuit of the ignition transistor and an additional resistor is connected between the base and the emitter thereof. When overvoltages across the primary winding cause breakdown of the Zener diodes, the current through the Zener diodes is blocked from the emitter-collector circuit of the auxiliary transistor either by a diode or by a blocking transistor having an emitter-collector circuit connected in parallel with the base-emitter circuit of the auxiliary transistor. The blocking transistor is maintained in the conductive state blocking the auxiliary transistor throughout the application time of an externally applied blocking signal which is adapted to maintain the ignition transistor in the blocked state.

摘要： A switch connected in series with the ignition coil is "on" and "off," respectively, in the presence and absence of a pulse furnished by a pulse generator operating in synchronism with the crankshaft of the engine. If the pulse width of the pulses is too small for the current in the ignition coil to reach the minimum value required for ignition, the closing time of the series switch is advanced, while if the pulse width is too long, causing excess heat dissipation in the coil, the closing time of the switch is retarded. To accomplish this, a first digital counter counts downwards for a predetermined time and upwards for a time period in which the current in the ignition coil exceeds a predetermined current. Upon interruption of the current in the coil, the then-present value in the first digital counter is transferred to a second digital counter. The second counter then counts down at a predetermined rate until a predetermined count is reached. At this time, the series switch is switched to the conductive state.

摘要： Oscillations which would normally occur when the current in the primary winding of an ignition coil is limited to a predetermined value prior to ignition are suppressed by use of a feedback resistor. Specifically, the basic circuit consists of the primary winding of the ignition coil connected in series with a Darlington transistor configuration which, in turn, is connected in series with a measuring resistor, at a common point. The input of the current control system is connected to the common point through an additional resistor, while the output of the control circuit is connected to the input base of the Darlington configuration. Oscillations which might otherwise occur are suppressed by the use of a feedback resistor connected between the input and output lines of the control circuit.
