Abstract

L'invention concerne un procédé de protection contre l'engazage d'un fluide caloporteur dans un système de refroidissement d'un moteur comportant un radiateur et un élément de régulation ouvrant un passage du fluide vers le radiateur à partir d'une première température (T1) de consigne atteinte par le fluide, le passage effectuant un dégazage au moins partiel du fluide. Il est effectué un comptage de durée d'ouverture (CDO) du passage et un comptage de durée d'engazage (CDE) totale du fluide dès que le moteur thermique est tournant comptabilisée tant qu'un dégazage au moins partiel prédéterminé considéré comme étant suffisant n'a pas été effectué lors d'un ou de plusieurs roulages (R, R+1) du véhicule. Une première durée d'ouverture (D1) du passage est prédéterminée comme étant suffisante pour effectuer ledit dégazage, les comptages de durées d'ouverture (CDO) et d'engazage (CDO) étant remis à zéro (Ri) dès que la première durée d'ouverture (D1) est atteinte.The invention relates to a method of protection against the gassing of a heat transfer fluid in a cooling system of an engine comprising a radiator and a regulating element opening a passage of the fluid to the radiator from a first temperature ( T1) set point reached by the fluid, the passage effecting at least partial degassing of the fluid. A counting of the opening time (CDO) of the passage and a counting of the total gas-filling time (CDE) of the fluid as soon as the heat engine is running are counted as long as a predetermined at least partial degassing considered to be sufficient. has not been carried out during one or more runs (R, R + 1) of the vehicle. A first opening duration (D1) of the passage is predetermined as being sufficient to effect said degassing, the counting of opening times (CDO) and of gas-gassing (CDO) being reset to zero (Ri) as soon as the first duration opening (D1) is reached.
