Definitions

  • the invention relates to an ignition device for internal combustion engines according to the preamble of claim 1 (DE-PS 27 59 154).
  • connection from the second secondary connection or, in the case of a plurality of ignition coils, from the common point via the sensor to the negative pole of the supply voltage can occasionally be interrupted, although experience has shown that ignition still occurs, but this cannot be optimal. This adversely affects the combustion process in the cylinders.
  • the measurement input of the subsequent ignition control circuit can be damaged due to the increased voltage and the control electronics of the engine control can be disturbed in its regular operation.
  • Figure 1 shows a circuit diagram of the ignition device according to the invention.
  • the primary winding 1 of an ignition coil SP is controlled via a switching transistor 3.
  • the first secondary connection of the secondary winding 2 leads to one or more spark plugs ZK and the second secondary connection is connected via a sensor 4 to the negative pole of a supply voltage source, not shown.
  • a further secondary coil of possible further ignition coils, the second secondary connections of which lead to the common point P, is indicated by dashed lines.
  • a measuring line 8 leads to a connection pin 10 of a microprocessor 16 contained in the ignition control device via a signal shaping circuit 17, which converts the measuring signals into square-wave signals with a harmless voltage amplitude.
  • the voltage limiter 6 is designed as a Zener diode.
  • a diagnosis line 9 leads from the connection point between the Zener diode 6 and the resistor 7 to a connection pin 11 of the microprocessor 16.
  • the measuring line 8 is optionally connected in addition to or instead of the connection to the connecting pin 10 via a peak rectifier 14 to a connecting pin 12 of the microprocessor 16, wherein a signal shaping circuit (not shown here) can also be provided between the peak rectifier 14 and the connecting pin 12, and the diagnostic line 9 is also optional additionally or instead of the connection to connection pin 11 via a peak rectifier 15 connected to a connection pin 13 of the microprocessor 16.
  • An indicator lamp L and an arrow A symbolically denote the signals activated by the microprocessor 16, which will be discussed in more detail later.
  • FIG. 2 shows a diagram of the measurement and diagnostic signals a) in the case of faultless operation and b) in the case of faulty operation.
  • the measuring and diagnostic signals are identified in FIG. 2 by numbers 8 to 13, which correspond to those lines or connecting pins from FIG. 1 on which these signals appear.
  • Roman numerals denote the cylinders of the internal combustion engine, the ignition pulses of which are assigned to the measurement and diagnostic signals. This cylinder assignment takes place in a known manner via cam and crankshaft pulses. In this way, the measurement and diagnostic signals can be evaluated separately for each cylinder.
  • the duration of the measurement signals from the microprocessor 16 is counted in real time in a known manner.
  • the pulses on the measuring line 8 reach a voltage amplitude which does not reach the pass threshold of the zener diode 6, so that a zero signal appears at the connecting pins 11 and 13 (dashed lines 11, 13 in FIG. 2a).
  • This diagnostic signal is evaluated by the microprocessor 16.
  • an indicator lamp L is switched on and / or an error is displayed or stored in the microprocessor 16 and, indicated by the arrow A in FIG. 1, is output as an error signal for further processing.
  • the measurement signal and / or the diagnostic signal are led via tip rectifiers 14 and 15 to connection pins 12 and 13 of the microprocessor 16 and can be evaluated there at a later point in time during the cycle time of the respective cylinder (until the ignition pulse of the next cylinder) when the microprocessor is no longer concerned with real-time measurement, see dotted lines 12 in FIGS. 2a) and 2b) and dash-dotted line 13 in FIG. 2b).
  • the peak value rectifier capacitors are discharged by a reset pulse.
