PCT No. PCT/SE97/01930 Sec. 371 Date Jul. 20, 1998 Sec. 102(e) Date Jul. 20, 1998 PCT Filed Nov. 17, 1997 PCT Pub. No. WO98/22708 PCT Pub. Date May 28, 1998An arrangement and a process for communication between an ignition module (ICM) mounted on an engine and a control unit (ECM). The ignition module includes detection circuits and signal processing stages in order to determine at least one combustion related parameter from detected ionization currents in the combustion chamber (22). The control unit (ECM) communicates with the ignition module via at least one bi-directional communication wire (KCQ or KKI). Via the communication wire the control unit activates the detection in the ignition module, and the ignition module sends a signal corresponding to the magnitude of the detected parameter to the control unit on the same communication wire. Activation and transfer of parameter data is conducted sequentially over the communication wire. |
