Abstract (en)
[origin: EP2112347A1] The circuit (1) has a cooling liquid outlet case (3) receiving a cooling liquid from an engine i.e. internal combustion engine (2). A cooling radiator (7) receives the liquid from the case. A thermostatic valve (5) closes the flow of the liquid between the case and the radiator. The valve is opened, when the temperature of the liquid in the case exceeds a threshold. A valve opening control controls intermittent opening of the valve, even when the temperature of the liquid in the case is lower than the threshold. An independent claim is also included for a method for controlling a cooling circuit.
