Abstract (en)
The invention is related to a pressurization system (10) of a cooling circuit of an internal combustion engine installed in an engine driven unit, comprising a coolant tank (14) integrated into the cooling circuit, a pressure source (12) comprising a pump (13), a pressurization line (16) connecting the pressure source (12) and the coolant tank (14) for pressurizing the coolant tank (14), and a control unit (20) for controlling the operation of the pump (13). The invention is characterized in that the pressurization system (10) further comprises at least one pressure sensor (24) disposed to detect a pressure within the cooling circuit, wherein the pressure sensor (24) is connected to the control unit (20) to communicate pressure data representing the detected pressure to the control unit (20), and the control unit (20) comprises a data interface (30) for receiving status data representing an operation state of the engine driven unit unit, and the control unit (20) is provided to control the operation of the pump (13) so as to regulate the pressure within the cooling circuit to a pressure level that is determined on the present status data received via the data interface (30).
