The present invention relates to lubricating oil compositions, and more particularly to lubricating oil compositions having excellent performance for use in engines, gears, bearings, and especially internal combustion engines equipped with catalytic converters. Generally, when lubricating oils are made to have lower viscosity with the aim of improving the fuel economy of internal combustion engines, the lubricating oil enters the realm of so-called mixed lubrication, and energy loss due to friction becomes a problem. Therefore, it is necessary to use an excellent friction modifier, but to date no effective one has been developed. In particular, in actual machines such as engines, gears, bearings, etc., various lubrication conditions are always mixed in mixed lubrication, and there are no practically effective friction modifiers that can be widely applied to such various lubrication conditions. I can't find it at all. On the other hand, internal combustion engines equipped with catalytic converters, which have recently been widely used for purposes such as exhaust gas purification,
Due to the problem of catalyst poisoning, it is necessary to reduce the phosphorus content in lubricating oil as much as possible. Therefore, there is a problem in that phosphorus compounds, which have a large friction improving effect, are inappropriate for use in internal combustion engines such as those described above. Therefore, the present inventor has devised a method which can overcome the drawbacks of the above-mentioned prior art, can be suitably used in an internal combustion engine equipped with a catalytic converter, has an excellent lubrication effect, and can significantly improve fuel economy. We conducted extensive research to develop a lubricating oil composition. As a result, it has been found that a lubricating oil composition containing a specific amount of a fatty acid partial ester of glycerin, a fatty acid, and, if necessary, a specific organometallic compound can achieve the objective. The present invention is based on this knowledge. That is, the present invention provides (A) 0.1 to 3.0% by weight of fatty acid partial ester of glycerin and (B) 0.01 to 1.0% by weight of fatty acid.
% by weight. Furthermore, in addition to both components (A) and (B) above, (C) oxymolybdenum sulfide organophosphorodithioate (hereinafter referred to as MoDTP) and/or dithiocarbamate metal salt (hereinafter referred to as M-
It's called DTC. ) is also provided. The composition of the present invention includes the above-mentioned base lubricating oil.
It can be obtained by containing components (A), (B), or even component (C), but the lubricating oil that serves as the base of the composition is widely used as a lubricating base oil of ordinary mineral oil type or synthetic oil type. However, lubricating oils used as engine oil, gear oil, bearing oil, etc. can also be used. Next, (A), (B), and (C) should be included in the above lubricating oil.
The components will be explained one by one. First, regarding the fatty acid partial ester of glycerin, which is component (A), there are no particular restrictions on the type of fatty acid that forms the partial ester, but it usually has 8 to 8 carbon atoms.
24 is preferred. Those with a carbon number of 7 or less are difficult to dissolve in base oil and have poor storage stability. Furthermore, those having carbon numbers of 25 or more are difficult to obtain and are not sufficiently effective. In addition, this ester is obtained by esterifying a portion of the three hydroxyl groups of glycerin, that is, one or two. Particularly preferred are those containing monoester as a main component. Examples of preferred partial esters include oleic acid monoglyceride, stearic acid monoglyceride, palmitic acid monoglyceride, myristic acid monoglyceride, palmitoleic acid monoglyceride, linoleic acid monoglyceride, lauric acid monoglyceride, and linoleic acid monoglyceride. Instead of the above partial ester, 3 of glycerin
So-called triglycerides, in which all of the hydroxyl groups are esterified, do not have a sufficient friction-improving effect. The content of the partial ester, component (A), should be in the range of 0.1 to 3.0% by weight based on the intended lubricating oil composition. Here, if it is less than 0.1% by weight, the desired effect cannot be achieved, and if it exceeds 3.0% by weight, problems arise in storage stability, which is inappropriate. The type of fatty acid that is component (B) is not particularly limited, but those having 8 to 24 carbon atoms are usually preferred. If the number of carbon atoms is 7 or less, it will vaporize and disappear due to its low boiling point, while if it is more than 25 carbon atoms, storage stability will be impaired. Preferred fatty acids include caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, oleic acid, linoleic acid, and linoleic acid. The content of the fatty acid component (B) should be in the range of 0.01 to 1.0% by weight based on the intended lubricating oil composition. Here, if it is less than 0.01% by weight, the desired effect cannot be achieved, and if it exceeds 1.0% by weight, it lacks storage stability. Furthermore, in the present invention, MoDTP and/or M-DTC as component (C) can also be blended as required. Here, MoDTP is usually a compound represented by the general formula [(RO) 2 PS-S] 2 Mo 2 S x O y , and various compounds can be considered depending on the type of R in the formula. R in the above formula is an alkyl group, cycloalkyl group, aryl group, alkylaryl group or arylalkyl group having 1 to 30 carbon atoms. Furthermore, x and y are positive real numbers that satisfy x+y=4. On the other hand, M-DTC is a general formula

R 1 and R 2 are an alkyl group, a cycloalkyl group, an aryl group, an alkylaryl group, or an arylalkyl group having 1 to 18 carbon atoms. Moreover, M in the formula represents a metal, and is either Mo, Cd, Ni, Zz or Sb. Note that n is 2 or 3 depending on the valence of the metal. Further, x and y are positive real numbers satisfying x+y=4. This M-DTC can be produced by various methods, and commercially available products may also be used. In the present invention, the above-mentioned (C) component is optionally used.
Either or both of MoDTP and M-DTC can be added. This MoDTP and M-
The content of DTC is not particularly limited, as long as it is present in a so-called effective amount in the lubricating oil composition. Specifically, MoDTP and M-
Preferably, DTC is in the range of 0.1 to 3.0 parts by weight. The composition of the present invention has the above-mentioned properties in the base lubricating oil.
It is prepared by containing components (A), (B), and, if necessary, component (C). The lubricating oil composition of the present invention thus obtained greatly contributes to lowering the coefficient of friction, and is therefore extremely effective in improving fuel economy, that is, energy saving, in internal combustion engines and the like. Furthermore, since it contains almost no phosphorus, it can be suitably used as engine oil for automobiles equipped with catalytic converters. It is of course also effective as gear oil and bearing oil. Next, examples of the present invention will be shown. Examples 1 to 3 and Comparative Examples 1 to 7 Lubricating oil compositions were prepared by adding predetermined amounts of component (A) and component (B) to 100 neutral oil as a base. Using the obtained lubricating oil composition as a sample,
NACA friction tests were conducted at a sliding speed of 13.6 cm/sec, a load of 1 kg, and an oil temperature of 100°C. The results obtained are shown in Table 1.
