The reload will also be terminated if the respective Primary current has reached a certain value.
- the second-mentioned object, an apparatus for carrying out the inventive Specify method is characterized by the features of claim 2 solved.
- a leakage circuit branch is used to detect the ignition current proposed, consisting of a series circuit, a Semiconductor diode and a bleeder resistor is constructed.
- the at the bleeder resistor occurring voltage drop is as Zündstromsignal a Zündstromausutehimiser supplied.
- this Zündstromauseptussiiser preferably constructed as a threshold circuit, after the abort the ignition current generates a first Nachladesignal.
- a development of the invention relates to the detection of the primary current by means of a measuring resistor through which this primary current flows, its voltage drop of a primary current evaluation unit as a primary current signal is supplied.
- this primary current evaluation unit also exists from a threshold circuit that stops charging, if the value of the primary current exceeds a certain value and time-delayed generates a second recharge signal when the primary current has fallen below the certain value again.
- the first and second reload signals are supplied to an AND circuit which inputs Control signal for the output stage generated, so that thereby the charging processes terminated or reloading initiated.

- Each ignition output stage comprises an ignition coil Tr 1 ... Tr 4 with a primary and secondary winding P 1 ... P 4 or S 1 ... S 4 , and a spark plug Zk 1 ... Zk 4 and one with the primary winding connected output stage E 1 ... E 4 , constructed as a semiconductor power switch.
- Each primary winding P 1 ... P 4 is connected with its one connection to a vehicle electrical system voltage U B of, for example, 12 V supplied by the on-board battery and with its other connection to the semiconductor power switch E 1 ... E 4 , which is also referred to as a starting transistor , connected.
- the ignition pulses U E1 ... U E4 generated by a control circuit 2 and distributed to the output stages are each supplied via a control line to the control electrode of these ignition transistors.
- the on-state of the ignition transistors E 1 ... E 4 is guided primary current I prim derived via a measuring resistor R4 to ground potential.
- the low-potential sides of the secondary windings S 1 ... S 4 are routed to a common circuit node S, which is once connected to generate an ion current signal with an inverting amplifier consisting of a differential amplifier 4 with an ion current measuring resistor R 1 fed back to the inverting input and, on the other hand for deriving the ignition current I sek resulting after ignition at a spark plug via a Ableitscönszweig composed of a series circuit of a Zündstrommeßwiderstandes R 2, a semiconductor diode D 1 and the emitter-collector path of a pnp transistor T to ground potential.
- the base electrode of this transistor T is driven by the output of the differential amplifier 4.
- both an ignition current signal U I, ignition and an ion current signal U I, Ion are available at this output of the differential amplifier 4.
- a constant reference voltage U ref2 preferably 5 V, is applied to the non-inverting input of the differential amplifier 4 , this constant reference voltage U ref2 being generated by a constant voltage source.

- the actual ignition current is, as already mentioned above, derived from the Zündstrommeßwiderstand R 2 of the semiconductor diode D 1 and the transistor T series circuit, which can be constructed without this transistor T, which serves only to increase the current carrying capacity of the differential amplifier 4. If such a transistor T is omitted, the cathode of the semiconductor diode D 1 is connected directly to the output of the differential amplifier 4, so that the Ableitscenszweig is connected in parallel to the ion measuring resistor R 1 .
- FIG. 4 Another possibility for generating a Zündstromsignales is shown in Figure 4, where the Zündstrommeßwiderstand R 2 is not arranged in the emitter branch of the transistor T, but in the collector branch, so that the measurement signal U I, ignition can be tapped off ground potential, which is for further processing This measurement signal is advantageous.
- a resistor R 4 in the supply line to the base of the transistor T limits the measurement error resulting from a base current to small values.
- the primary current I pr of the already mentioned measuring resistor R 4 is provided, which is supplied as the primary current signal U i, pr the inverting input of a comparator 9, while at its non-inverting input a reference voltage U ref1 is applied.
- the value of this reference voltage U ref1 is chosen so that at the output of the comparator 9, a high signal is applied, as long as the value of the primary current I pr is less than 30 A.
- the voltage applied to the output of this comparator 9 signal U 30A is supplied to an AND circuit 3, whose output is connected to the control circuit 2.
- the ignition current signal U I, Zünd which is available at the output of the differential amplifier 4, is evaluated by a threshold circuit 5, which serves as an ignition current evaluation unit, and generates a first charging signal U I, sec as a high signal, if the value of the secondary current I sec is greater than - 10 mA, that is almost zero.
- This ignition current signal U I, Zünd is also supplied to the AND circuit 3.
- this Ionenstromrohsignal is also a high-pass filter 8 supplied with a cut-off frequency of 5 kHz, which also supplies the high-pass filtered ion current signal U ion, HP for knock detection of the control unit 1.
- This control unit 1 assumes the function of an engine management system by supplying ignition signals for the individual cylinders of the control circuit 2 via four lines 1a, which in turn together with the control signals U B / n L obtained via the AND circuit 3 and one of these downstream inverter circuits 10 E1 ... U E4 for controlling the output stages E 1 ... E 1 . derived.
- Corresponding actuators are controlled via outputs A.
- an OR circuit 12 connected to the lines 1a derives an ignition cycle signal U st , which determines the duration of each ignition cycle via the AND circuit 3.
- a sequence of a plurality of individual pulses is generated, each pulse of which leads to a spark.
- Such a sequence of charging and firing cycles during an ignition cycle is shown with the pulse-shaped curve 2 in the pie chart of Figure 3.
- This illustration corresponds to an operating point of the internal combustion engine with a speed of 2000 1 / min at an ignition timing of 30 ° before top dead center TDC.
- the small radius of this curve 2 corresponds to a charging cycle and the large radius of this curve 2 a burning phase.
- the charging and burning phase of a conventional transistor ignition is shown with the curve 1a and 1b, where the charging phase according to the curve 1a approximately at 90 ° before top dead center TDC and the burning phase according to the curve 1b at 30 ° before top dead center OT begins.
- the burning phase is already completed 20 ° before top dead center TDC, while in the inventive ignition to the top dead center OT, the charging and burning cycles are continued.
- an ignition cycle begins at time t, with a first charging process on the primary coil (cf. FIG. 2b).
- the further course is determined by the levels of the primary current signal U 30A and the first recharging signal U -10mA , that of the AND circuit and this downstream of the negative circuit 12 to a signal U B / nL . be processed, as shown in Figure 2f.
- a secondary current I sec is generated, which flows as ignition current from the circuit node S into the secondary coil. Since the value of this ignition current is less than -10 mA, the first charging signal U -10 mA is reset to the low level at the output of the threshold value circuit 5 (see FIG.
- the primary current signal U 30A again assumes its high level with a time delay of a few ⁇ s (see FIG. 2C).
- the ignition current decays, ie reaches a value that is above -10 mA.
- the second charge signal in turn assumes its high level so that all the input levels applied to the input of the AND circuit 3 are high, thus at time t 2 another charging begins (see Figure 2b), which in turn aborts is, if the primary current I pr has exceeded the value of 30 A.
- the time t 3 is exceeded, whereby the ignition cycle signal U st is reset to the low level, so that no further charging phase can be initiated.
- FIG. 2g shows the course of the ignition signal U E4 of the associated output stage E 4 , whose rising and falling edge is determined by the level of the output signal U B / nL at the inverter circuit 12.
- the rising edge is determined either by the rising edge of the ignition cycle signal U st or by the first charging signal U -10mA
- the falling edge is determined by the falling edge of the primary current signal U 30A .
- the duration of a Set ignition cycle whose duration between 0.2 ms and any Duration is adjustable, whereby the ignition to be supplied to the ignition energy not only with regard to the current operating parameters of the internal combustion engine, but also with regard to the present directly to the ignition coils Operating conditions are optimized. Because these operating parameters detect both the primary and secondary currents at the ignition coils, can be spoken of an energy-controlled ignition.
- the circuit used for ion current and secondary current measurement has the advantage that a measuring voltage of less than 40 V required is. Therefore, the Meßwoodser Wegung and ion current evaluation with low-cost low-voltage components in a simple way be performed. Due to the circuit topology, the Deriving the ignition currents normal semiconductor diodes are used, the significantly lower leakage currents than the commonly used Zener diodes respectively.
- dissipation resistor R 3 which is inserted between the circuit node S and the low-potential side of each secondary coil S 1 ... S 4 .
- Two anti-serially connected zener diodes Z 1 and Z 2 are connected in parallel with this dissipation resistor R 3 .
- These components serve, after the tearing of the spark, so at the end of the burning time to quickly reduce the residual energy still remaining in the secondary winding or in the secondary capacity.
- the value of this dissipation resistance R 3 will usually be in the range between 10 k ⁇ and 100 k ⁇ and thus causes a rapid dissipation of the energy.
- the two zener diodes Z 1 and Z 2 are necessary for limiting the voltage drop across the dissipation resistor R 3 , which would otherwise result in a considerable reduction of the ignition energy.
- an ignition current of, for example, 100 mA at a resistance of, for example, 50 k ⁇ would cause a voltage drop of 5000 V.
- the zener voltages of the Zener diodes Z 1 and Z 2 are therefore chosen so that only a small reduction of the ignition energy occurs, for example in the amount of 50 V.
- the inverting differential amplifier 4 converts this ion current into the already mentioned ion current signal U I, Ion , which is supplied as a measurement signal of the ion current of the already mentioned ion current evaluation unit 6.
- the secondary winding S 1 ... S 4 of the ignition coils Tr 1 ... Tr 4 supplied MeBlement U Meß which may be between 5 and 30 V, preferably at 20 V, is constant during the entire lonenstrommeßdauer. Since the ion current is in the ⁇ A range, a differential amplifier 4 is used with a low input current, which is currently available at low cost. Due to the low-impedance provision of this measuring voltage U Meß accounts for transhipment of stray capacitances, as in other systems with AC load, such. B. knocking combustion can occur. This advantage is particularly noticeable when several ion measuring sections are operated in parallel, as shown in FIG. 1, since effective stray capacitances can then multiply.
- control unit 1 The division of the functions between the control unit 1 and the adjacent circuit parts can also be realized differently. So it is also possible that the control unit 1 more functions, such. B. the integration of the ion current signal (instead of the integrator 7), the function of the comparators 5 and 9, the AND function of the AND circuit 3 or instead of the control circuit 2, the control of the output stages E 1 to E 4 takes over.
