    Abstract: The invention concerns a liquid detection system of an internal combustion engine (1) to detect undesired liquid in at least one cylinder of the engine. The system comprises an electric motor (4) to rotate a crank shaft (2) of the internal combustion engine (1), a frequency converter (6) to supply power to the electric motor, a measuring sensor (9) to measure current of the electric motor, and a control unit (8) to receive measurements of the measuring sensor (9). The control unit (8) is arranged to stop the electric motor (4) if the measurement value exceeds a threshold value.
