Definitions

  • the present invention is within the field of lubricants. More specifically, it relates to a new lubricant composition which has been found to possess outstanding properties, especially in connection with two-stroke cycle engines. Accordingly, the invention also relates to the use of said lubricant composition as a lubricant for a two-stroke cycle engine. Furthermore, the invention relates to a two-stroke cycle engine fuel comprising said novel lubricant composition.
  • the present invention is based on a completely different approach to solve the problems referred to.
  • a specific group of fatty acid-alkyl esters can replace the lubricating base oil up to a considerable proportion thereof to give an outstanding lubricant composition for two-stroke cycle engines, in spite of the fact that said lubricant composition can be imparted a much lower viscosity than that hitherto considered necessary or proper for engines of the type referred to.
  • said alkyl esters may be derived from vegetable oils, e.g. rapeseed oil, and concerning such esters per se reference can be made to for instance EP 626 442 A1 and U.S. Pat. No.
  • Another great advantage in connection with the present invention is related to the fact that the fatty acid-alkyl esters referred to can be obtained from in-expensive and renewable vegetable sources.
  • the new lubricant composition according to the invention is cheap as well as less harmful to the environment.
  • natural or synthetic non-mineral oil-based lubricants available today are rather expensive, which has indeed delayed the use of more environmentally adapted products.
  • the lubricant composition also further contains 0.1-20% by weight of C) conventional lubricating oil additive(s), said percentage being based on the total weight of the lubricant composition, i.e. of A)+B)+C).
  • the lubricant composition comprises 50-80, e.g. 60-80 or 60-75, % by weight of said fatty acid-(C 1 -C 4 )alkyl ester.
  • fatty acid-(C 1 -C 4 )alkyl ester a preferable embodiment thereof is represented by the case where the fatty acid portion of said ester comprises at least 60% by weight, preferably at least 70% by weight, of C 16 -C 18 -fatty acid(s).
  • the fatty acid-(C 1 -C 4 )alkyl ester is derived from a vegetable oil.
  • vegetable oils in this connection are olive, peanut, corn, cottonseed, rapeseed, soybean, linseed, castor, coconut, palm, peanut, safflower, sesame, sunflower and tallow oils.
  • the (C 1 -C 4 )alkyl portion of said fatty acid-(C 1 -C 4 )alkyl ester may be methyl, ethyl, propyl and butyl (with straight or branched chains where applicable). Methyl and ethyl are, however, preferable, methyl being especially preferable.
  • the lubricating base oil used in the composition can be any one or any mixture of conventional base oils used in lubricant, preferably two-stroke, compositions. In other words, it is generally selected from lubricating natural, e.g. mineral, and synthetic oils.
  • oils are hydrocarbon oils alkylene oxide polymers, esters of mono- or polyfunctional carboxylic acids and polyfunctional alcohols, poly(alkylene)glycols, etc.
  • esters can be found within the following groups:
  • Natural triglyceride esters for instance from the following sources: castor, coconut, corn, cottonseed, linseed, olive, palm, palm kernel, peanut, rapeseed, safflower, sesame, soybean, sunflower and tallow oils;
  • Synthetic polyol esters based on polyols such as neopentyl glycol (NPG), trimethylol propane (TMP) and pentaerythritol (PE), esterified with fatty acid(s), e.g. from the following sources: castor, coconut, corn, cottonseed, linseed, olive, palm, palm kernel, peanut, rapeseed, safflower, sesame, soy, sunflower and tallow oils;
  • Dimerate esters such as esters based on dimerized fatty acids (e.g. C 36 dimer acid esters) and alcohols (e.g. monofunctional alcohols).
  • the lubricating base oil is selected from environmentally friendly natural or synthetic esters, such as those types disclosed above, Most preferably such esters are selected from the above-mentioned synthetic polyol and sugar polyalcohol fatty acid esters.
  • esters are selected from the above-mentioned synthetic polyol and sugar polyalcohol fatty acid esters.
  • additive(s) C) a preferred range thereof is 0.1-10% by weight, for instance 0.1-5% by weight, based on the weight of A)+B)+C).
  • additive(s) can be chosen completely along the lines of the prior art, for instance in connection with two-stroke cycle engines and for purposes similar to those of the prior art.
  • lubricity base ingredients A) and B) of the lubricant composition impart such good properties to the lubricant composition that some or many conventional additives may be reduced or even omitted in the composition.
  • they are, however, preferably selected among lubricity improvers, viscosity improvers, combustion improvers, corrosion and/or oxidation inhibiting agents, pour point depressing agents, extreme pressure agents, antiwear agents, antifoam agents, detergents, dispersants, antioxidants and metal passivators completely along the lines of the prior art.
  • One preferable additive to be used in the lubricant composition claimed is, however, polyisobutylene and derivates thereof, for instance in an amount of 2-10, such as 3-8, % by weight, based on the weight of A)+B)+C).
  • Examples of derivates of polyisobutylene are amine and succinic acid derivates thereof.
  • the viscosity of the lubricant composition is generally much lower than that of previously known lubricants for similar purposes. Generally this means that the (kinematic) viscosity thereof, at 100° C., is within the range of 1-10 cSt. Preferably said viscosity is within the range of 1-6 cSt and more preferably within the range of 2-5 cSt.
  • the lubricant composition according to the present invention is presented especially in connection with lubrication of two-stroke cycle engines, it is not per se restricted to such use only. Thus, it may well be useful as a lubricant for other engines or in industrial applications. However, since the lubrication of two-stroke cycle engines is especially interesting, another aspect of the present invention is represented by the use of the lubricant composition as defined above for the lubrication of, or as a lubricant for, a two-stroke cycle engine.
  • the lubricant composition is of a relatively low viscosity
  • one preferable embodiment of said use is in connection with an engine where the lubricant composition is supplied to said engine separately from the fuel for the same. That is, a separate lubrication of a two-stroke cycle engine is more easily achieved by means of a low viscosity lubricant composition, the pumpability at low temperature being a great advantage as compared to today's high viscosity lubricants.
  • the lubricant composition may well be combined or mixed directly into the fuel for a two-stroke cycle engine, as is common practice today. Therefore, still another aspect of the present invention is represented by a fuel composition for a two-stroke cycle engine, which comprises a fuel for said engine together with a lubricant composition as defined above.
  • a preferable embodiment of such a fuel composition is a composition wherein said lubricant composition constitutes 0.5-4, more preferably 1-3, such as 1-2, % by weight, based on the weight of said fuel.
  • a sample thereof, S1 was prepared and tested at two different laboratories. At one laboratory said sample S1 was also compared with a commercial mineral-oil based two-stroke engine oil, S2, and at the other laboratory sample S1 was compared with a commercial, synthetic and biodegradable ester-based two stroke engine oil, S3.
  • Another lubricant composition according to the present invention, S11 was also prepared and tested at an independent laboratory, where it was also compared with said commercial mineral-oil based two-stroke engine oil S2.
  • Samples S1 and S11 according to the present invention were prepared by mixing the following components in the following percentages: Amount (% by weight) Component S1 S11 Lubricating base oil: 25.0 15.0 (Sugar-C 4 -C 18 -fatty acid ester) Fatty acid-(C 1 -C 4 ) alkyl ester: 62.3 77.7 (Rapeseed-methyl ester) Additives: Paraffinic solvent 5.0 0.8 Calcium alkyl phenate 0.3 0.3 Calcium sulfonate 0.3 0.3 Polyisobutylene 4.0 3.0 Derivative of polyisobutylene 0.4 0.4 and succinic acid Polyisobutylene amine 2.5 2.5 Poly alkyl methacrylate 0.2 —
  • the kinematic viscosities of S1 and S11 were 10.40 cSt at 40° C. and 3.15 cSt at 100° C. (S1), and 7.74 cSt at 40° C. and 2.65 cSt at 100° C., respectively (S11).
  • This test on a Husqvarna 346 two stroke chainsaw engine is a high temperature detergency test with resistance against ringsticking as the main result information.
  • Samples S1 and S2 were tested under identical conditions and the test results are presented below. The tests were carried out with an oil-gasoline mixture containing 2% by volume of oil.
  • the kinematic viscosity of S2 (ASTM D 445) was 58 cSt at 40° C. and 9.2 cSt at 100° C.
  • the test consists of a breaking in phase and a high temperature load phase.
  • the engine is held at full throttle at 8400 r/min, except for 5 idle phases (5 min).
  • This test on a HVA 242 chainsaw engine is similar to the test disclosed in Example 1 performed on a HVA 346 chainsaw engine and reference can thus be made to said Example 1 concerning test details.
  • test includes the following;
  • test cycle has the following sequence:
