- the addition amount thereof must be 800 ppm or less in terms of a phosphorus content. As long as the addition amount is 800 ppm or less, the amount of high-temperature deposits generated is nearly immune to the phosphorus concentration . However, when the phosphorus concentration exceeds 800 ppm, the amount of high-temperature deposits generated abruptly increases.

- high-temperature deposit refers to insoluble matter resulting from the lubricating oil composition for an internal combustion engine, the insoluble matter being produced at high temperatures of 300°C or 400 °C or more.
- the adhesion and deposition of such high-temperature deposits to, for example, the inside of an engine or the bearings of a supercharger may induce a reduction in performance of the engine or the supercharger, or trouble in the engine or the supercharger.
- the major feature of the lubricating oil composition for an internal combustion engine of the present invention is that the amount of high-temperature deposits generated is small.
- the composition may be evaluated by any one of the known tests for observing high-temperature deposits, the composition is preferably evaluated by a TEOST33C test (ASTM D6335) adopted by the International Lubricant Standardization and Approval Committee (ILSAC) because an additionally strict evaluation can be performed.

Description
- The present invention relates to a lubricating oil composition for an internal combustion engine, and more specifically, to a lubricating oil composition for an internal combustion engine having excellent fuel-saving property and high-temperature deposit-preventing performance.
- A lubricating oil for internal combustion engines of automobiles or the like plays roles such as the lubrication and cooling of the inside of the engine, and the cleaning and dispersion of combustion products . In recent years, to prevent global warming, there has been a growing demand for the suppression of carbon dioxide emissions through improvements in the fuel efficiency of automobiles or the like. Accordingly, a fuel-saving-type lubricating oil for an internal combustion engine obtained by providing a lubricating oil for an internal combustion engine with a function of improving fuel efficiency has been studied and used.
- Fuel-saving-type lubricating oils for internal combustion engines reduce friction occurring in an internal combustion engine to improve the fuel efficiency of the engine. Specifically, an organic molybdenum-based friction modifier such as a molybdenum dithiocarbamate is generally blended as an additive (friction modifier) for reducing the friction. However, lubricants for internal combustion engines blended with organic molybdenum-based friction modifiers are apt to generate high-temperature deposits because of poor oxidation stability under high temperatures. In particular, recent lean-burn engines, direct-injection engines, or the like have higher efficiency than conventional engines, and their combustion temperatures tend to increase. Accordingly, problems due to generation of high-temperature deposits have become serious.
- In view of the foregoing, various methods have been proposed for reducing the high-temperature deposits. For example,
Patent Document 1 discloses a multigrade engine oil composition for an engine with a turbocharger, the composition being characterized by using a mineral oil and/or a synthetic oil having a kinematic viscosity of 1.5 to 13 cSt (100°C) as a base oil, and containing, as essential components, 3 to 40 mass% of (A) a mineral oil and/or a synthetic oil having a kinematic viscosity of 16 to 45 cSt (100°C) and 0.5 to 15 mass% of (B) a viscosity index improver. In addition,Patent Document 2 discloses a lubricating oil composition for an internal combustion engine characterized by using, as a base oil, a lubricating oil component that has a kinematic viscosity at 100°C of 2 cSt to 13 cSt and contains 1 mass% or more of a heavy component having a boiling point of 480°C or more in a boiling point range measured by gas chromatograph distillation with reference to the total mass of the lubricating oil base oil. In addition, the paragraphs [0021] to [0026] ofPatent Document 2 disclose that an organic molybdenum-based compound can be used as a friction modifier. -

- where R1 to R4 each represent a linear or branched alkyl group or alkenyl group having 4 to 18 carbon atoms, and X1 to X4 each represent an oxygen atom or a sulfur atom.
- R1 to R4 of the general formula (1) represent a linear or branched alkyl group or alkenyl group having 4 to 18 carbon atoms. Examples of such group include: alkyl groups such as a butyl group, an isobutyl group, a tertiarybutyl group, a pentyl group, an isopentyl group, a neopentyl group, a tertiary pentyl group, a hexyl group, an isohexyl group, a heptyl group, an isoheptyl group, an octyl group, a 2-ethylhexyl group, an isooctyl group, a nonyl group, an isononyl group, a decyl group, an isodecyl group, an undecyl group, an isoundecyl group, a dodecyl group, an isododecyl group, a tridecyl group, an isotridecyl group, a tetradecyl group, an isotetradecyl group, a hexadecyl group, an isohexadecyl group, a stearyl group, a 2-butyloctyl group, a 2-butyldecyl group, a 2-hexyloctyl group, a 2-hexyldecyl group, a 2-octyldecyl group, a 2-hexyldodecyl group, and a monomethyl branched-isostearyl group; and alkenyl groups such as a butenyl group, an isobutenyl group, a pentenyl group, an isopentenyl group, a hexenyl group, a heptenyl group, an octenyl group, a nonenyl group, a decenyl group, an undecenyl group, a dodecenyl group, a tetradecenyl group, and an oleyl group. Among them, an alkyl group is preferred because of its high friction-reducing effect, an alkyl group having 6 to 16 carbon atoms is more preferred, and an alkyl group having 8 to 13 carbon atoms is still more preferred. It should be noted that R1 to R4 may be identical to or different from one another.
- X1 to X4 each represent an oxygen atom or a sulfur atom, all of X1 to X4 may be oxygen atoms or sulfur atoms, and X1 to X4 may be a mixture of oxygen atoms and sulfur atoms. However, the ratio of oxygen atom/sulfur atom (molar ratio) preferably falls within the range of 1/3 to 3/1 because a high friction-reducing effect and low corrosiveness are obtained.
- The organic molybdenum compound may be one kind or a mixture of two or more kinds. The amount of the compound to be added to the lubricating oil composition for an internal combustion engine of the present invention is as indicated in appended
claim 1. When the addition amount is small, there are cases where a friction-reducing effect is not obtained. In addition, when the addition amount is excessively large, high-temperature deposits outstripping the effect of the high-temperature deposit-preventing performance of the lubricating oil composition for an internal combustion engine of the present invention may be generated. Accordingly, the compound is added at a molybdenum content of 200 to 2,000 ppm, more preferably 200 to 1,500 ppm, still more preferably 300 to 1,000 ppm with respect to the total amount of the lubricating oil composition for an internal combustion engine of the present invention. - The component (B) used in the present invention is a base oil having a kinematic viscosity at 100°C of 25 mm2/s or more, and a mineral oil-based base oil, a synthetic base oils, or a mixed oil thereof can be used as such base oil. A paraffin-based mineral oil and a naphthene-based mineral oil can be given as examples of the mineral oil-based base oil, and a solvent-refined oil, oil obtained by a hydrogenation treatment, wax-isomerized oil, or the like of any such oil may be used. For example, a poly-α-olefin, a polyisobutylene (polybutene), a diester, a polyol ester, or a polyphenyl ether can be used as the synthetic base oil. Among them, a paraffin-based mineral oil such as a bright stock and a high-viscosity poly-α-olefin are preferred.
- One kind of these base oils can be used alone, or a mixture of two or more kinds thereof can be used, as the component (B). However, the kinematic viscosity at 100°C of the component must be 25 mm2/s or more, and is preferably 25 to 100 mm2/s, more preferably 25 to 80 mm2/s, still more preferably 30 to 60 mm2/s. When the kinematic viscosity at 100°C is less than 25 mm2/s, the high-temperature deposit-preventing performance is not sufficiently exerted. In addition, when the viscosity is excessively high, there are problems such as cases where it may be difficult to handle the component or it takes a long time to uniformly blend the component. Accordingly, the kinematic viscosity is preferably 100 mm2/s or less.
- The blending amount of the component (B) is s indicated in appended
claim 1. When the blending amount is excessively small, there are cases where the effect of the high-temperature deposit-preventing performance may not be exerted. In addition, when the blending amount is excessively large, it may be difficult to set the kinematic viscosity at 100°C of the lubricating oil composition for an internal combustion engine of the present invention to 12.5 mm2/s or less, or its low-temperature viscosity may increase to reduce its fuel-saving effect. In view of the foregoing, the blending amount of the component (B) is 1 to 30 mass%, more preferably 3 to 25 mass%, still more preferably 5 to 20 mass% with respect to the total amount of the lubricating oil composition for an internal combustion engine of the present invention. - The component (C) used in the present invention is a base oil having a kinematic viscosity at 100°C of less than 12.5 mm2/s. A mineral oil-based base oil, a synthetic base oil, or a mixed oil thereof can be used as such base oil, and examples of such base oil include: mineral oil-based base oils such as a paraffin-based mineral oil and a naphthene-based mineral oil, oils obtained by subjecting these mineral oils to a solvent refining treatment, a hydrogenation treatment, and a wax isomerization treatment, and a mineral oil obtained by combining two or more of these treatments; and synthetic oils such as poly-α-olefins and polyisobutylenes.
- When the kinematic viscosity of the component (C) is 12. 5 mm2/s or more, a lubricating oil composition having a kinematic viscosity in the range specified in the present invention cannot be produced. In addition, even when the kinematic viscosity of the component (C) is less than 12.5 mm2/s, in the case where the component is a base oil having an excessively high viscosity, the amount of the high-viscosity base oil that can be added is reduced, and hence it may be unable to efficiently alleviate the generation of high-temperature deposits or the low-temperature viscosity of the lubricating oil composition for an internal combustion engine of the present invention may increase to reduce its fuel-saving effect. Accordingly, the kinematic viscosity at 100°C of the component (C) is preferably 1 to 11 mm2/s, more preferably 2 to 8 mm2/s, still more preferably 2 to 5 mm2/s.
- Further, the viscosity index of the component (C) is preferably 100 or more, more preferably 110 or more, still more preferably 120 or more from the viewpoint of improving fuel-saving properties. When the viscosity index of the low-viscosity base oil is less than 100, the low-temperature viscosity of the lubricating oil composition for an internal combustion engine as the end product increases, with the result that the fuel-saving effect is not obtained in some cases.
- The component (C) has to be blended in such an amount that the lubricating oil composition for an internal combustion engine of the present invention blended with any other additive or the like has a kinematic viscosity at 100°C of 5 mm2/s to 12.5 mm2/s. Specifically, the component has only to be blended in an amount of 50 to 95 mass%, preferably 60 to 85 mass% with respect to the total amount of the lubricating oil composition of the present invention.
- In addition, the lubricating oil composition for an internal combustion engine of the present invention containing the components (A) to (C) must have a phosphorus content of 800 ppm to 500 ppm.
- Although trace amounts of phosphorus may be present in a base oil, most of phosphorus is derived from a phosphorus-based additive to be added to the lubricating oil composition for an internal combustion engine. Examples of the phosphorus-based additive include metal-containing additives such as molybdenum dithiophosphate and zinc dithiophosphate; extreme-pressure agents such as monooctyl phosphate, dioctyl phosphate, monooleyl phosphate, dioleyl phosphate, tributyl phosphate, triphenyl phosphate, tricresyl phosphate, triphenyl phosphite, tributyl phosphite, tricresyl phosphite, and a thiophosphoric acid ester; and detergents such as calcium phosphate, magnesium phosphate, and barium phosphate.
- Although one or more kinds of those phosphorus-based additives may be added, the addition amount thereof must be 800 ppm or less in terms of a phosphorus content. As long as the addition amount is 800 ppm or less, the amount of high-temperature deposits generated is nearly immune to the phosphorus concentration . However, when the phosphorus concentration exceeds 800 ppm, the amount of high-temperature deposits generated abruptly increases. However, when the phosphorus concentration is excessively low, the lubricating oil for an internal combustion engine may be poor in wear resistance or oxidation-preventing property. Accordingly, phosphorus is present in a certain amount or more. The phosphorus content may be 300 to 800 ppm. According to the invention is 500 to 800 ppm. Further, the phosphorus compound most suitable for the addition is a zinc dithiophosphate excellent in wear resistance and oxidation-preventing property.
- The lubricating oil composition for an internal combustion engine of the present invention has a kinematic viscosity at 100°C of 5 mm2/s to 12.5 mm2/s. When the kinematic viscosity is less than 5 mm2/s, there is a possibility that oil film does not sufficiently form and hence wear occurs at sliding surfaces. When the kinematic viscosity is more than 12.5 mm2/s, the following problem arises. The oil film becomes so thick that friction loss increases to impair fuel-saving performance.
- The term "high-temperature deposit" as used in the present invention refers to insoluble matter resulting from the lubricating oil composition for an internal combustion engine, the insoluble matter being produced at high temperatures of 300°C or 400 °C or more. The adhesion and deposition of such high-temperature deposits to, for example, the inside of an engine or the bearings of a supercharger may induce a reduction in performance of the engine or the supercharger, or trouble in the engine or the supercharger.
- The major feature of the lubricating oil composition for an internal combustion engine of the present invention is that the amount of high-temperature deposits generated is small. Although the composition may be evaluated by any one of the known tests for observing high-temperature deposits, the composition is preferably evaluated by a TEOST33C test (ASTM D6335) adopted by the International Lubricant Standardization and Approval Committee (ILSAC) because an additionally strict evaluation can be performed. The smaller the amount of high-temperature deposits, the better. Specifically, the amount is preferably 40 mg or less, more preferably 30 mg or less in the TEOST33C test because nearly no reduction in performance of an engine or in performance of a supercharger is observed at the time of practical use.
- One or more kinds of additives such as viscosity index improvers, pour point depressants, extreme-pressure agents, oiliness improvers, antioxidants, metal-based detergents, ashless dispersants, metal deactivators, rust inhibitors, and anti-foaming agents are preferably added to the lubricating oil composition for an internal combustion engine of the present invention as long as the effects of the present invention are not impaired. Further, when any such additive is blended, particular attention needs to be paid so that the phosphorus content with respect to the total amount of the lubricating oil composition for an internal combustion engine will be 800 ppm to 500 ppm.
- Examples of viscosity index improvers include poly(C1 to C18)alkyl methacrylates, (C1 to C18)alkyl crylate/(C1 to C18)alkyl methacrylate copolymers, diethylaminoethyl methacrylate/(C1 to C18)alkyl methacrylate copolymers, ethylene/(C1 to C18)alkyl methacrylate copolymers, polyisobutylenes, polyalkylstyrenes, ethylene/propylene copolymers, styrene/maleic acid ester copolymers, and styrene/isoprene hydrogenated copolymers. Alternatively, a dispersion-type or multi-functional viscosity index improver to which dispersing performance has been imparted may be used. Its weight-average molecular weight is about 10,000 to 1,500,000, preferably about 30,000 to 1,000, 000. Such viscosity index improver is blended in an amount of preferably 0.1 to 20 mass%, more preferably 0.3 to 15 mass% with respect to the lubricating oil composition for an internal combustion engine.
- Examples of pour point depressants include polyalkyl methacrylates, polyalkyl acrylates, polyalkylstyrenes, and polyvinyl acetates. Its weight-average molecular weight is about 1,000 to 100,000, preferably about 3,000 to 80,000. Such pour point depressant is blended in an amount of preferably 0.005 to 3 mass%, more preferably 0.01 to 2 mass%, with respect to the lubricating oil composition for an internal combustion engine.
- Examples of extreme-pressure agents include: sulfur-based additives such as sulfurized oils and fats, olefin polysulfides, and dibenzyl sulfides; phosphorus-based compounds such as monooctyl phosphate, tributylphosphate, triphenylphosphite, tributyl phosphite, and thiophosphoric acid esters; and organic metal compounds such as metal salts of thiophosphoric acid, metal salts of thiocarbamic acid, and metal salts of an acidic phosphoric acid ester.

- Examples of oiliness improvers include: higher alcohols such as oleyl alcohol and stearyl alcohol; fatty acids such as oleic acid and stearic acid; esters such as oleyl glycerine ester, stearyl glycerine ester, and lauryl glycerine ester; amides such as lauryl amide, oleyl amide, and stearyl amide; amines such as laurylamine, oleylamine, and stearylamine; and ethers such as lauryl glycerine ether and oleyl glycerine ether.

- Hereinafter, the present invention is specifically described by way of examples. It should be noted that the term "%" in the following examples and the like refers to "mass%" unless otherwise stated.
- Lubricating oil compositions for internal combustion engines (test oils) used in tests were produced in accordance with the recipes shown in Table 1 and Table 2 below, and were then subjected to the TEOST33C test and a fuel-saving property test by the following methods. Table 1 and Table 2 show the results. It should be noted that Table 3 shows a base oil used in blending and its properties.
- A test was performed in conformity with the test method of ASTM D6335 with a TEOST33C tester (manufactured by Tannas Co.).
FIG. 1 is a schematic view of the TEOST33C tester. The specific test method is as described below. While a rod (metal rod) (2) in a case (1) of the apparatus illustrated inFIG. 1 was heated and cooled so that its temperature was as shown inFIG. 2 , a certain amount of a test oil was made to flow from a reaction chamber (4) storing the test oil into the rod (2) in the case (1) by a pump (3). The step is defined as 1 cycle and the cycle was repeated 12 times. After that, the rod was taken out, and then the mass of deposits adhering thereto and the mass of deposits in the test oil obtained by filtering the total amount of the test oil through a filter were measured. The total of the masses was defined as a high-temperature deposit amount. Further, certain amounts of air containing moisture and a nitrogen monoxide gas were blown into the test oil in the reaction chamber (4). Further, air bubbled in 30 ml of water in a 50-ml flask was used as the air containing moisture. - Detailed test conditions are described below.
