ABSTRACT:
The present invention provides a device and a method for cylinder sensing in an internal combustion engine. The device according to the invention has a crankshaft sensor device for detecting a crank angle and a predetermined crankshaft position, and outputting corresponding crankshaft signals; an ignition device for igniting the respective cylinder of the internal combustion engine by generating corresponding high-voltage pulses for corresponding control signals, and a control device for receiving the crankshaft signals and outputting the control signals to the ignition device as a function of at least the crankshaft signals, with the control device being so designed that in a cylinder sensing phase, while receiving a crankshaft signal corresponding to a predetermined crankshaft position, it outputs a control signal to generate a high-voltage pulse with a predetermined amplitude that can be reached in at least one specific cylinder; an ignition detection device for determining whether and/or at what ignition voltage the specific cylinder was ignited by the high-voltage pulse and outputting a corresponding ignition detection signal; and a cylinder sensing device for determining whether the specific cylinder is in the predetermined crankshaft position in its power stroke, based on at least the ignition acquisition signal.
