| 摘要 |
The invention relates to an evaluation circuit for detecting the cylinder assignment of an internal combustion engine using a signal which is capacitively output at the ignition coil (1) with respect to a particular first potential for cylinder assignment, having a window formation unit which forms an evaluation window for the signal capacitively output at the ignition coil with respect to the particular first potential or a signal (A4, A5) derived therefrom by detecting that time range in which the secondary voltage of the ignition coil (1) is above a primary voltage determined by a spark burning voltage. |
