Title (EN) LOW ASH LUBRICANTS WITH IMPROVED SEAL AND CORROSION PERFORMANCE
(FR) LUBRIFIANTS À FAIBLE TENEUR EN CENDRES PRÉSENTANT DES PERFORMANCES D'ÉTANCHÉITÉ ET DE CORROSION AMÉLIORÉES
Abstract: front page image
(EN)A lubricant composition of (a) an oil of lubricating viscosity; (b) a dispersan comprising the condensation product of a carboxylic functionalized polymer with an aromatic amine having at least 3 aromatic rings and at least one primary or secondary amino group; and (c) an overbased metal detergent comprising an oil -soluble neutral metal salt component and a metal carbonate component, provides good seal and corrosion performance. The total amount of neutral metal salt component in the lubricant composition is at least about 0.75 percent by weight and the sulfated ash level of the lubricant composition is less than about 1.1 percent.
(FR)L'invention concerne une composition lubrifiante comprenant (a) une huile de viscosité lubrifiante ; (b) un dispersant comprenant le produit de condensation d'un polymère à fonctions carboxyliques avec une amine aromatique contenant au moins 3 cycles aromatiques et au moins un groupe amino primaire ou secondaire ; et (c) un détergent métallique surbasique comprenant un composant de sel de métal neutre soluble dans l'huile et un composant de carbonate de métal, qui confère de bonnes performances d'étanchéité et de corrosion. La quantité totale de composant de sel de métal neutre dans la composition lubrifiante est d'au moins environ 0,75 pour cent en poids et la teneur en cendres sulfatées de la composition lubrifiante est inférieure à environ 1,1 pour cent.
