    In an ignition system with glow plugs (11) the filament thereof is supplied with power from a generator (10) via a switch device (12). The power is controlled so that the constant glow temperature level is obtained, i.e. a predetermined resistance in the filament. This one is associated with a measure bridge (13) which during a short interval at the beginning of every heat current cycle is switched on when generator power is not yet supplied to the plug. The balance of the bridge, saying that the glow plug is too hot or too cold, is registered for the present cycle by a comparator (18) in which the balance is converted into a logical signal to be a basis for the on/off regulation by the switch device in the heating circuit of the plug.

    The invention relates to electrical equipment for internal combustion engines, in particular, to ignition systems for the fuel mixture of internal combustion engines.
    The purpose of the invention is to increase the reliability and efficiency of the ignition system with a glow plug by maintaining the set glow plug temperature with a high accuracy.
    Fig. 1 is a circuit diagram of an ignition system with a spark-plug; figure 2 - diagram of the system.
    The ignition system consists of an alternating current generator 1 with the first 2 and second 3 power buses, between the first bus 2 and the first vertex 4 of the measuring diagonal of the Wheatstone bridge 5, which is the glow plug filament temperature sensor 6, the glow filament current regulator 7 is turned on candles. The three shoulders of the Wheatstone bridge 5 are formed by the first 8, second 9 and third 10 resistors, respectively. The fourth shoulder is formed by a filament 6 of the glow of a spark-plug. The first top of the diagonal of the power supply of the Wheatstone bridge is connected to the second bus 3 of the alternator 1 alternator. To the busbars 2 and 3 of the generator are connected the inputs of the pulse driver 12, the output of which is connected to the inputs of the first 13 and second 14 single vibrators. The output of the first one-shot 13 is connected to the first input of the trigger 15 and with the control input of the transistor switch

    The ignition system works as follows.
    An alternator 1, driven by an internal combustion engine (not shown), provides power to the ignition power circuits (Fig. 2a), including block 7 and filament 6 of the ignition lamp. The remaining blocks are fed from rectifier. The current (temperature) of the filament 6 of the plug is measured by a temperature sensor made in the form of a Wheatstone bridge 5, the three arms of the Wheatstone bridge are formed by resistors
    8-10, with resistor 9 being variable. With the help of a resistor
    9, the balancing of the bridge 5 is controlled. The test pulses are applied to the vertices 11 and 17 of the diagonal of the power bridge 5 through a transistor switch 16. These pulses generate voltage pulses on the vertices 4 and 18 of the measuring diagonal of the bridge 5,
    the inputs of the comparator 19 are connected. The comparator 19 operates in the mode of a switch that implements the operation mode, for example, a differential relay. Consequently, either a logical 1 or a logical O is removed from the output of the comparator, depending on which vertex of the measuring diagonal has a higher potential with respect to the second vertex.
    The signal of comparator 19 is detected by trigger 15 for at least one generator period.

    The test pulses are provided by the first one-shot 13, the output of which at the beginning of each positive period of the voltage of the generator 1 is applied to the control of the input of the transistor switch 16 (Fig. 2b).
    Thus, the measurement of the temperature of the filament 6 of the candle filament occurs at the moment when the generator current 1 is not supplied to the candle, which is a characteristic feature of the test pulse. The current of the generator 1 is controlled by the block 7 for controlling the filament of the filament 6 of the candle, which is in; | In this case, it is made on two parallel-counter-connected thyristors controlled by pulses from the output of the element 20.
    The pulses controlling the unit 7 are somewhat delayed relative to the pulses from the output of the first one-oscillator 13. As a result, the unit 7 begins to conduct current from the generator 1 after the test pulses (Fig. 2b) have already passed. However, the test pulse may not be missed by the AND 20 element if there is no pulse from trigger 15 due to the unbalance of the bridge, for example, if the temperature of the glow plug is above a certain minimum. The control pulses are transmitted by the AND element 20, if the trigger 15 during the trial period determines that the candle filament 6 is too cold. Then the thyristors of the block 7 begin to conduct — one during the positive half period, and the other during the negative half period. power is supplied from generator 1 during the entire period. The need for energy supply for A fallen candle is also determined during the next period by a breakdown in bridge 5, which thus begins this period. Blocks 13-16, 19, and 20 are designed to maintain a constant temperature of the glow plug regardless of the speed of the generator 1 and the ambient temperature. The temperature level of the glow plug can be varied by adjusting the tiled resistor 9 in bridge 5.
    Figure 2 shows some of the voltages used in the proposed system. The only source of current for supplying power to the components of the circuit is the alternator I, the voltage of which is represented by a sinusoid. A voltage pulse shaper 12, supplemented by zener diodes (not shown), generates, as a result of this curve, a rectangular voltage (Fig. 26) with a phase delay (hysteresis). This voltage is applied to single-oscillators 13 and 14, which feed control pulses (Figure 2b) for the bridge test and trigger pulses (Figure 2d), respectively. The single-oscillator 14 is triggered from the driver 12, as well as from the single-oscillator 13 (not shown) and, therefore, the number of pulses (FIG. 2d) is doubled compared to the number of pulses (FIG. 2b)
