Abstract

Système de régulation de température dans un moteur à combustion interne refroidi par liquide équipé d'un radiateur, qui commande l'état d'une soupape de régulation du débit servant à réguler le débit d'un fluide de régulation de température à travers un passage ménagé dans le moteur. Des sondes détectent une température de régime moteur, telle que la température de l'huile moteur. De préférence, lesdites sondes détectent également la température du fluide de régulation de température ainsi que la température de l'air ambiant. Un ordinateur moteur reçoit des signaux des sondes et compare ces signaux à une ou plusieurs valeurs prédéterminées. Dans un mode de réalisation, l'ordinateur moteur compare le signal de température de l'huile moteur à une valeur prédéterminée pour régler l'actionnement de la soupape. Dans un autre mode de réalisation, l'ordinateur corrige une valeur de température prédéterminée du fluide de régulation de température sur la base de la comparaison entre le signal de température de l'huile moteur et la valeur prédéterminée de température de l'huile moteur. L'ordinateur compare ensuite le signal de température du fluide de régulation de température à la température corrigée dudit fluide. Il actionne la soupape de régulation du débit sur la base de la comparaison entre le signal de température du fluide de régulation de température et la température corrigée dudit fluide. La valeur de température prédéterminée de l'huile moteur et la valeur de température prédéterminée du fluide de régulation de température varient de préférence avec la température de l'air ambiant.
