    摘要: 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.

    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: 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: 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: 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.
