A method for generation of a low test voltage is used for the purpose of detecting an ionization current in the spark gap of an internal combustion engine. The voltage is generated by a controllable ignition magneto (5) arranged in order to charge (2) an ignition capacitor (4). The voltage is applied (3) to the primary side of the ignition device after generation of a spark and after the decay of the spark, after which the ionization current is detected (11) on the secondary side of the ignition device.
[ We claim:] [1.] A method for the generation of a voltage for detecting an ionization current in a spark gap of an internal combustion engine, comprising the steps of:(a) providing a controllable ignition magneto on a primary side of an ignition device in order to charge an ignition capacitor;(b) igniting a spark in the spark gap;(c) after decay of the spark, connecting the ignition magneto to a special primary winding on the primary side, as a low-tension source, so as to generate an ionization measuring voltage; and(d) detecting an ionization current ...
