| description | A coolant composition containing (1) an alkylene glycol such as propylene glycol, (2) a corrosion inhibitor combination of an azole such as tolyltriazole, a molybdate salt and phosphoric acid and (3) less than 10 weight percent of water exhibits high temperature stability and corrosion inhibition for metals used in internal combustion engine cooling systems, particularly such metals as aluminum and magnesium and a process of cooling such an engine.
Composition de réfrigérant contenant (1) un alkylène glycol tel que du propylène glycol, (2) une combinaison d'inhibition de la corrosion comprenant un azole tel que le tolyltriazole, un sel de molybdate et de l'acide phosphorique et (3) moins de 10 % d'eau. Cette composition présente une stabilité aux températures élevées et une résistance à la corrosion pour des métaux utilisés dans des systèmes de refroidissement de moteurs à combustion interne, en particulier des métaux tels que l'aluminium et le magnésium. L'invention concerne également un procédé de refroidissement d'un tel moteur. |
