Abstract

The invention relates to a diesel locomotive oil composition and application thereof, and mainly solves the problems of insufficient high temperature detergency and the sludge dispersibility when the railway diesel locomotive oil composition is used in a railway internal combustion engine system in the prior art. The diesel locomotive oil composition solves the problem well by adopting the technical scheme, the oil composition is prepared from, by weight, a, 3-10 parts of metal detergent, wherein the metal detergent is composed of 0.5-3.5 parts of sulfonate, 0.5-3.5 parts of vulcanized alkylphenol and 2-9 parts of salicylate; b, 3-7 parts of low molecular weight polyisobutene succinimide ashless powder, the molecular weight range is 3000-3200; c, 0.5-3 parts of phosphorus-containing anti-wear preservative; d, 0.5-3 parts of complex antioxidant; e, 80-95 parts of base oil. The technical scheme can be used in the industrial production of railway internal combustion locomotive oil composition.

Description

technical field [0001] The invention relates to a diesel locomotive oil composition and its application. Background technique [0002] Railway diesel locomotive oil is mainly used in the internal combustion engine system of railway locomotives. The working conditions of railway internal combustion engine oil are very harsh. The oil will generate sludge, paint film, carbon deposit and other oxidized substances during use, which will lead to problems such as oil circuit blockage and piston ring wear. Improving the cleaning and dispersing ability of oil products can better disperse some precursors of sludge, varnish, and carbon deposits in oil products, thereby effectively inhibiting the formation of various oxidation products. [0003] The document CN200310104206 discloses a lubricating oil for a railway locomotive internal combustion engine, which has a good anti-wear and extreme pressure function. [0004] Document CN02131228 discloses a modified engine oil that can be use...
