摘要：
The aim of the invention is to detect the hydrostatic lock before in a more reliable way (1). The starting event system is equipped with a speed measurement arrangement (8, 9) and a control unit (7). The control unit has an acceleration calculation unit (10) to calculate acceleration of the crankshaft (6) by using the received speed measurement data. The system is further provided with an air compression device (11) and an air delivery arrangement (14, 15, 16) to deliver the compressed air into cylinders (2) of the engine in order to rotate the crankshaft slowly. The control unit (10) is further provided with a detector unit (19) that is in connection with the acceleration unit in order to detect a hydrostatic lock in at least one cylinder of the engine.
