(57) Abstract :
The invention concerns a method and a device for regulating engine temperature, the device comprising a valve control system (3)
arranged on a pipe (3) of a cooling circuit of an internal combustion engine (1) connecting the engine (1) to a radiator (2), the pipe
(11) including a temperature sensor (101) arranged at the engine output (1) and upstream of the valve control system (3) which is
automatically opened under the effect of a cooling liquid being heated to a set temperature in accordance with a predetermined
setpoint profile, ranging between a minimum stored temperature setpoint (CI) and a maximum stored temperature setpoint (C2), so
that the temperature of the engine gradually reaches the minimum or maximum setpoint by maintaining the control valve system more
or less wide open, and means for controlling (45, TC) the initial opening of the control valve system enabling the opening of the
control valve system to be controlled when the control valve system has already been initially opened.
