Abstract

Una composicion lubricante para motor diesel que comprende un stock base, un dispersante y un antioxidante que comprende un compuesto de organomolibdenotrinuclear soluble en aceite de la formula genérica: Mo3Sx-(Q) donde x es de 4 a 10, preferiblemen te 7, y Q es un grupo inicial, que puede ser un ligando, ypor lo menos otro compuesto seleccionado de un compuesto fenolico y un compuesto amínico; y un método para controlar la viscosidad de una composicionlubricante. La composicion es capaz de cont rolar la viscosidad del lubricante en la presencia de hollín y mantener la dispersabilidad del dispersante. Lascomposiciones minimizan el desgaste en los motores y las emisiones indeseables de los escapes causadas por la combustion incompleta de vehí culos que usanmotores diesel y lubricantes para los mismos. La combinacion de antioxidante actua mejor al controlar el incremento de viscosidad inducido por hollín que loscompuestos individuales.A lubricating composition for diesel engine comprising a base stock, a dispersant and an antioxidant comprising an oil-soluble organomolibdenotrinuclear compound of the generic formula: Mo3Sx- (Q) where x is 4 to 10, preferably 7, and Q it is an initial group, which may be a ligand, and at least one other compound selected from a phenolic compound and an amino compound; and a method to control the viscosity of a lubricant composition. The composition is capable of checking the viscosity of the lubricant in the presence of soot and maintaining the dispersibility of the dispersant. The compositions minimize engine wear and undesirable emissions from leaks caused by incomplete combustion of vehicles using diesel engines and lubricants for them. The antioxidant combination acts better by controlling the increase in soot-induced viscosity than the individual compounds.
