Abstract (en)

[origin: EP2602477A2] The ignition circuit has ignition coil (34) that generates ignition spark at spark plug (20) arranged in combustion chamber. A control unit (32) controls the ignition coil. A sensor circuit (37) is configured to supply a voltage to sensor. The sensor circuit is connected to ignition module on the one hand and to reference potential (40) on the other hand. The sensor circuit and power circuit (35) are configured to use the line segment (33) as a common connection to reference potential. The control unit and ignition coil being consolidated in a common component as an ignition module (31) to which generator (12) is connected. The spark plug is located outside of the ignition module. The power circuit is formed by connecting spark plug and ignition coil. A sensor is configured to detect operating parameters of engine and to transmit an output signal to ignition module.
