Abstract
The ignition device of an internal combustion engine has at least one ignition coil in an ignition coil assembly and a secondary side device for ignition testing by detection of a secondary voltage signal from a secondary side from the ignition coils. The device for detecting the secondary voltage signals includes a standard measuring point device (13) at the outer periphery (P) of each ignition coil assembly, comprising advantageously a capacitive electrode, for capacitive read out of the secondary voltage signal from the secondary side of each of the ignition coils (1) in each of the ignition coil assemblies. A conductor (12) is connected electrically with the measuring point device (13) and capacitively to another conductor (8) connected to the secondary side of the ignition coil to transmit the secondary voltage signal from the secondary coil of each ignition coil (1) to the measuring point device (13). A capacitive signal receiver (14) is mounted on the outer periphery of the ignition coil assembly (11) in the vicinity of the measuring point device (13) of each of the ignition coil assemblies (11).
