Title (EN) METHOD AND DEVICE FOR REGULATING THE TEMPERATURE OF AN INTERNAL COMBUSTION ENGINE
(FR) PROCEDE ET DISPOSITIF DE REGULATION DE LA TEMPERATURE D'UN MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) 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 (C1) 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.
(FR) Procédé et dispositif de régulation de la température moteur, le dispositif comportant un système de vannage (3) disposé sur une conduite (11) d'un circuit de refroidissement d'un moteur (1) à combustion interne reliant le moteur (1) à un radiateur (2), la conduite (11) comportant un capteur (101) de température disposé en sortie du moteur (1 ) et en amont du système de vannage (3) dont l'ouverture est activée automatiquement sous l'effet d'un réchauffement du liquide de refroidissement à une température consigne caractérisé en ce qu'il comporte des moyens (31) permettant de faire varier la température consigne selon un profil de consigne déterminé, compris entre une valeur consigne de température mémorisée minimum (C1) et une valeur consigne de température mémorisée maximum (C2), afin que la température du moteur atteigne progressivement la valeur de consigne minimum ou maximum par le maintient d'une ouverture plus ou moins grande du système de vannage, et des moyens de contrôle (45 ,TC) de première ouverture du système de vannage permettant de contrôler que la première ouverture du système de vannage a déjà eu lieu.
