Definitions
- the invention is based on an ignition system according to the preamble of the main claim.
- Ignition systems with the suppression of a faulty ignition signal after starting up the ignition system are already known from DE-PS 39 17 808.
- the ignition signal supplied by the control unit is combined with the output signal of a delay circuit which, for example, delays the crankshaft angle signal for a predetermined time after the power supply has been switched on, as a result of which the control signal for the ignition output stage is also delayed.
- the delay takes place, for example, by means of an RC element.
- the implementation of a switch-on spark suppression is relatively complex due to the use of a timing element. Ultimately, there is none
- each control output of the control unit is immediately pulled to an active low level. Another advantage is that the low level at the output is maintained until the supply voltage required for the control unit is established.
- control device output is switched to ground via a voltage-controlled switch, as a result of which no additional control current is necessary for this switch.
- a voltage-controlled switch for example a MOS-FET
- the outputs of the control unit are each connected to a common line, and thus via an in the common line MOS-FET are connected to ground.
- the individual MOS-FETs are controlled as a function of the supply voltage. For example, the GATE can be sent to the
- FIG. 1 shows the basic structure of an ignition system, each control output for an ignition output stage being connected to ground via a voltage-dependent switch
- FIG. 2 shows the ignition system from FIG. 1, the outputs of the control unit being connected to a voltage-dependent switch via a bus line.
- a terminal 10 for example the ignition lock outlet of the internal combustion engine, is connected via a resistor 11 to a DRAIN input of a MOS-FET 12, which is connected to ground 13 via SOURCE.
- a supply voltage VCC is conducted to the control input GATE 14 of the MOS-FET 12, two diodes 15 and 16 being connected between the supply voltage VCC and the GATE.
- a connection 17 leads from the DRAIN input of the MOS-FET 12 to GATE connections of further MOS-FETs 18 to 18, where n corresponds to the number of ignition output stages to be controlled.
- a Zener diode 22 is connected in parallel with the MOS-FET 12 to intercept voltage peaks against ground 13.
- MOS-FETs 18 to 18 are each led with their DRAIN connection to the outputs A1 to An of an integrated driver module 19.
- This driver module 19 is connected at its terminal 20 to the supply voltage VCC.
- the driver module 19 is also connected via its outputs A1 to An on the one hand at Z1 to Zn to the ignition output stages (not shown), it does not matter whether it is a rotating or static high-voltage distribution, and on the other hand they are via the MOS-FET 18 up to 18 n to ground 13.
- the circuit just described has the following mode of operation.
- the ignition lock 10 When the ignition lock 10 is switched on, there is a high level at each GATE of the MOS-FET 18 to 18 via the resistor 11, as a result of which they are in the conductive state, ie all outputs AI to An are connected to ground 13 so that the ignition output stages are blocked and no current flows in any of the associated ignition coils.
- the current at the outputs A1 to An is in each case limited by a resistor 21 located in the main circuit of the MOS-FETs 18 1 and 18 n .
- the supply voltage VCC After switching on the ignition, the supply voltage VCC will not be immediately available due to delay or switching times and capacitive charging.
- the further MOS-FET 12 is turned on via the supply voltage VCC connected to its GATE 14, the value at which the GATE 14 is connected to VCC being determined via the dimensioning of the diodes 15 and 16 .
- the drive voltage of the MOS-FET 18 to 18 is pulled towards ground potential, ie towards zero, as a result of which the MOS-FETs 18 block 1 to 18 n and the triggering of the ignition output stages Z1 to Zn can take place via outputs A1 to An.
- FIG. 2 also shows a circuit for switch-on spark suppression, which is constructed similarly to the circuit in FIG. 1. Therefore, the same reference numerals have been used for the same components.
- a tap is led from each control output A1 to A6 to a collecting line 22, a diode 23 is connected in the forward direction from the tap at the output of the control device to the collecting line 22.
- This bus 22 is connected to the DRAIN connection of a MOS-FET 24 connected to ground via the resistor 21, so that all outputs A1 to A6 are connected to ground 13 when the supply voltage VCC is not fully built up.
- This circuit is thus reduced compared to the circuit from FIG. 1, so that a MOS-FET does not have to be provided for each output of the control device for controlling an ignition output stage, but rather the outputs can be connected to ground via a bus and a single MOS-FET.
- the circuit described here was constructed with an n-channel MOS-FET, although other types of switches are also conceivable.
- the output stage locking shown in FIGS. 1 and 2 at the terminals ZI to Zn can either take place externally at the individual outputs of the control device or can already be implemented internally in the ignition control device 25, which then has the outputs Z1 to Zn.
- a realization in the ignition control device 25 would have the advantage that no additional components would be necessary.
- a voltage-controlled switch for example a MOS-FET of an enhancement type, can also be used.
