摘要： The primary of the ignition coil is tapped to provide two partial primary portions which are serially connected; during an initial current flow, only one partial portion has current flowing therethrough, the other partial portion being short-circuited. When the current through the coil has risen to a predetermined level, as sensed by current flow through a sensing resistor, the short circuit across the second partial portion is removed so that current can continue to flow through the entire primary, causing a substantial drop in current level but maintaining the stored inductive energy. Current can thus rise rapidly initially, so that the coil will store sufficient energy to initiate sparking at high speeds of the connected internal combustion engine while, at low speeds thereof, the overall current flow through the coil is decreased.

摘要： A capacitor which is charged by recurring square waves of a normally functioning microprocessor discharges at a steady rate, so that if the square waves do not continue, an operational amplifier will switch over and produce a reset pulse for the microprocessor. Repeated transitions of one polarity of the square wave recharge the capacitor during a short interval terminated by a second operational amplifier when the capacitor reaches a fixed level of charge. This second amplifier, which has feedback coupling, also initiates the timing discharge of the capacitor. A diode network at its output prevents charging the capacitor in the static state. This arrangement makes it unnecessary to provide another capacitor for quickly recharging the capacitor to prevent its discharge from switching over the first-mentioned operational amplifier.

摘要： In order to increase the closure angle of an interrupter switch connected in series with the primary winding of an ignition coil with increasing engine speeds, a capacitor is connected to the input of a trigger circuit whose output controls this closure angle. The capacitor is charged through a diode while the trigger circuit is switched out. The voltage across the capacitor shifts the threshold of the trigger circuit in a direction increasing the time that the interrupter switch is conductive. The charge on the capacitor is controlled by a signal generator which furnishes an output signal having an amplitude increasing with increasing engine speeds. The closure angle of the interrupter switch therefore also varies as a function of engine speed.

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： A power output stage has a Darlington-pair circuit (11, 12) for switching an inductive load, especially the ignition coil of an internalcombustion engine. In order to predetermine the operating mode of the power output stage, a switch (24) is provided which bridges the base-emitter junction of the Darlington-pair circuit (11, 12), is closed in the event of a quick disconnection of the output stage, and is opened in the event of a voltage-limited disconnection of the output stage. A voltage divider, which consists of at least two resistors (16, 18) and bridges the switching junction of the Darlington-pair circuit (11, 12), is connected by means of its pick-off to the junction point between the switch (24) and the base of the Darlington-pair circuit (11, 12), the switch (24) being connected in parallel with a part (18) of the voltage divider. When the switch (24) is open, the Darlington-pair circuit is consequently raised again upon reaching a lower limiting voltage of, for example, 35 volts over the resistor (16), so that, in the case of driving an ignition coil, a spark-free disconnection is achieved. Only a very few, simple and cheap components are required for this purpose.

摘要： A timing wave generator 26 provides the same input to two threshold switches that switch on at approximately the same time but have different switching hysteresis. The switch with the smaller hysteresis can affect ignition timing only through a delay circuit while the other can do so directly. If the engine stalls the delay circuit will assure that the primary current is shut off in a short time. In normal operation the large hysteresis of one of the threshold switches is in control and provides insensitivity to disturbance, but during startup the characteristics of the delay circuit can provide the appropriate ignition timing.

摘要： When the engine accelerates, the angle over which the ignition switch is closed prior to initiating the spark is automatically increased. Acceleration of the engine is detected by a comparator which compares the value of a speed-dependent signal in sequential cycles and initiate closure of the ignition switch if a predetermined difference is exceeded between the so-compared signals at a predetermined time in the cycle. Under static or decelerating conditions, the speed-dependent signal is compared, in each cycle, to the output of an integrator circuit. The integrator circuit integrates in a first direction at a first rate up to the above-mentioned predetermined time in the cycle and in the opposite direction at a second predetermined rate for the remainder of the cycle. The average value of the integrator output signal corresponds to the engine speed. When the so-compared signals are equal, the second comparator furnishes an output signal which closes the ignition switch. The integrating rates may be varied as a function of operating parameters of the engine.
