Definitions

  • the invention relates to a method for ignition monitoring of an ignition system with a storage choke, on which the electrical energy required to generate an ignition spark is stored, and an ignition coil, to which this energy is transmitted for generating the ignition spark, and a device for ignition monitoring of an ignition system with a Storage choke, on which the supply voltage is connected, and an ignition coil connected in parallel.
  • an ignition system for an internal combustion engine it is desirable to detect a misfire, that is to say the absence of an ignition spark, in order, for example, to prevent the fuel supplied to the engine from not being burned, which can lead to destruction of the catalyst, in particular in the case of an exhaust system with a catalyst .
  • the object underlying the invention is therefore to develop a method and an apparatus, i.e. to create a circuit arrangement of the type mentioned at the beginning with which a clear detection is possible as to whether an ignition spark is present between the electrodes of the spark plugs supplied by the ignition system or whether a short circuit or shunt has occurred or the ignition coil is not under load on the high voltage side, which is e.g. the case is when the ignition cable has fallen off.
  • This object is achieved in the method according to the invention in that the voltage difference between the voltage rise at the storage inductor and the supply voltage and the voltage difference across the storage inductor are detected and the absence of at least one of these voltage difference signals is evaluated as an indication of a fault in the ignition system.
  • the circuit arrangement according to the invention stands out by three voltage handles for the supply voltage and for the two voltages on the storage inductor, which supply corresponding voltage signals, and an evaluation circuit which, in the absence of at least one of these voltage signals, generates an error signal.
  • the design according to the invention also offers the possibility of measuring the spark life, the circuit arrangement according to the invention being able to be produced at low cost and requiring little space.
  • the ignition system shown in Fig. 1 consists of a storage inductor L0, to which the supply voltage + UB is located and in which energy is stored via a transistor T0, which is switched through by a control when a switch S0 is closed, between the storage inductor L0 and an ignition coil ZSP0 connected in parallel to it, the ignition coil ZSP0 is transmitted.
  • the secondary winding of the ignition coil ZSP0 is connected in the usual way to the spark gap of a spark plug.
  • voltage signals are tapped at the storage choke L0. These voltage signals are the voltages U20 and U21 on both sides of the storage inductor L0, and additionally the supply voltage UB, which are shown in FIGS. 3b and 4c.
  • the voltages U20 and U21 are the voltage increase at the connection of the storage inductor L0, at which the supply voltage + UB is located, and the voltage increase at the collector of the switching transistor T0.
  • a diode D0 which only allows a current in the direction of the storage inductor L0, and two capacitors C0, C1 are connected, the other connection of which is connected to ground.
  • the voltage taps for the voltage + U21, + U20 and the supply voltage + UB are direct or via resistors R1, R2 (+ U21, + UB) and a Zener diode ZD1 (+ UB ) connected to a circuit, preferably in the form of two optocouplers Opt0 and Opt1, connected in series, with a logic AND function, which logically combines the voltage differences U20-UB and U21-U20.
  • a transistor T1 which serves as a switch, is at its base due to the voltage drop controlled at the resistor R3 and is connected with its collector-emitter path, for example via a resistor R6, between the output of the optocoupler Opt0 and ground.
  • a resistor R5, which is connected upstream of the base of the transistor T1, serves to limit the current.
  • a voltage UA which is representative of the state of the spark gap of the ignition system, is tapped at the collector of transistor T1 via resistor R6. If this voltage UA has a high potential, then there is an error.
  • the circuit arrangement according to the invention with the structure shown in detail in FIG. 2 operates in the following way:
  • the diode D0 is provided which, when the storage inductor L0 is discharged, prevents this voltage surge + U20 from being short-circuited via the network.
  • the capacitors C0 and C1 integrate the pulse occurring when the storage choke L0 is discharged.
  • the voltage rise + U20 at capacitor C1 provides a direct statement about the load on the ignition coil ZSP0 (shunt of the ignition electrodes).
  • the voltage rise + U21 at the collector of transistor T0 is also used for the evaluation.
  • the corresponding voltage difference U21-U20 is present over a period of time that corresponds to the spark life at the electrodes.
  • the two voltage difference signals U21-U20 and U20-UB are linked via the outputs of the optocoupling Opt0, Opt1 according to the logical AND function.
  • the two optocouplers Opt0, Opt1 therefore form an AND gate.
  • Resistor R3 no voltage drop. As a result, the voltage UA tapped at the transistor T1 is at a high value. Since the voltage across resistor R3 is only present for as long as a spark is present between the ignition electrodes, this signal can be used to measure the burning duration, which also makes it possible to make a statement about the condition of the electrodes.
  • the integration element consisting of capacitor C2 and resistor R4 is provided. As long as periodic ignition takes place, the transistor T1 conducts, so that the output voltage UA is at a low value.
  • This output voltage UA of the transistor T1 can therefore provide a direct and unambiguous statement about the load on the ignition coil and whether the ignition coil is short-circuited or not.
  • the circuit arrangement according to the invention makes this possible with a simple, inexpensive construction of simple components with a simple connection (no high voltage), and in addition to the clear statement as to whether a spark is present between the electrodes, there is also the possibility of controlling the erosion of the electrodes, since a burn duration measurement is possible.
