Definitions
- the invention relates to an ignition system according to the type of the main claim, as is known for example from DE-OS 37 31 393.
- high-voltage switches are used, which are preferably arranged on the secondary side in the spark plug connector.
- Tilting diode cascades are used as high-voltage switching elements, 10 to 50 tipping diode elements being stacked on top of one another according to the dielectric strength of a single tipping diode and depending on the desired tipping voltage.
- Such a high-voltage semiconductor switch which suddenly changes from the blocking to the conducting state, makes it possible to practically eliminate the effects of shunts on the spark plug. Because of their inherent capacitance, long ignition lines behind the breakover diode cascade have a disadvantageous effect on the division effect of the breakover diode cascade, which is why the high-voltage semiconductor switch is preferably arranged in the plug connector.
- the arrangement according to the invention with the characterizing features of the main claim has the advantage that, regardless of the installation location of the high-voltage semiconductor switch in the form of a tilting diode cascade, an additional capacitor between the ignition coil and high-voltage semiconductor switch is arranged on the secondary side in parallel with the secondary winding, so that even with a low system capacity ⁇ a sufficiently high voltage jump at the spark plug is achieved.
- the measures listed in the subclaims enable advantageous further developments and improvements of the ignition system specified in the main claim. It is particularly advantageous to use a ceramic capacitor which is temperature-dependent in such a way that the amplification of the splitting effect is only effective when cold starting, and the capacitance of the capacitor decreases sharply during operation due to heating. As a result, the increased energy requirement of the ignition system and thus the increased load on the ignition coil by the capacitor is limited to the very short cold start phase.
- FIG. 1 shows the basic structure of an ignition system
- FIG. 2 shows an ignition system with double spark coils
- FIGS. 3a and 3b show possibilities for the installation location of the high-voltage semiconductor switch
- FIG. 4 shows an ignition system with a capacitor that can be switched off on the secondary side.
- FIG. 1 shows the basic structure of an ignition system with an ignition coil 1, the primary winding 2 of which is connected via an ignition transistor 3 to a voltage supply U, for example to the battery, not shown, of a motor vehicle.
- the ignition transistor 3 is controlled in a known manner via a control terminal 4.
- the secondary winding 5 is connected to ground potential on the one hand and on the other hand via a breakover diode cascade 6, which acts as a high-voltage semiconductor switch, and an interference suppressor 7 to the spark plug 8.
- the ignition system shown in Figure 1 works as follows.
- FIG. 2 shows a structure similar to that of FIG. 1, but a double spark coil is used here.
- a trigger diode cascade 6 is assigned to each end of the ignition coil, the distinction being made here by corresponding indices a and b.
- These breakover diode cascade are assigned to the coil ends with different polarity.
- the capacitor 9 for amplifying the steepening effect is connected in parallel with the secondary winding 5 in front of the breakover diode cascades 6a and 6b. Similar to FIG. 1, the breakover cascades and the capacitor are arranged in the ignition coil housing 10 in this embodiment.
- FIGS. 3a and 3b show a structure similar to that in FIG. 1, the capacitor 9 being arranged in the ignition coil housing in both cases.
- the Kippdioden- * cascade in the plug cap 11 and ange ⁇ in Figure 3b in the candle 12 assigns. This has the advantage that the self-capacitance of the ignition line can also be used for the division effect.
- FIG. 4 also shows a construction similar to that of FIG. 1, but here a high-voltage switch 13 is arranged in series with the capacitor 9, parallel to the secondary winding 5.
- This high-voltage switch can be a light-triggerable high-voltage switch, for example.
- the capacitor 9 in the ignition coil housing and the high-voltage breakover diode, for example in the distributor rotor, the distributor middle plug, in the ignition line between the ignition coil and distributor or directly in the ignition coil.
