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 viscosity of the lubricant oil used has generally been related to the lubricity properties thereof. Therefore, a certain viscosity has been considered compulsory to achieve an adequate lubrication.
- 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 Al and US 5 713 965 as prior art. From said prior art it can be seen that such esters have been proposed primarily as fuels for diesel engines. However, although they are mentioned incidentally also in connection with lubricants, the specific use according to the present invention is neither disclosed nor suggested.
- the present invention is thus based on the finding that a specific group of fatty acid- alkyl esters can replace a considerable proportion of previously used lubricating base oils to give an outstanding new lubricant composition especially well suited for two-stroke cycle engines. Said esters may even represent the major ingredient of the base oils of such lubricant compositions, in spite of the fact that such proportions may give a lubricant composition having up to four or five times lower viscosity than lubricant compositions utilised today.
- 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 inexpensive and renewable vegetable sources.
- the new lubricant composition according to the invention is cheap as well as less harmful to the environment. Contrary thereto, natural or synthetic non- mineral oil-based lubricants available today are rather expensive, which has indeed delayed the use of more environmentally adapted products.
- Other advantages of the new lubricant composition should be obvious to a person skilled in the art after having read the more detailed description of the invention presented below. Description of the invention
- a novel lubricant composition comprising
- 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 ⁇ -C 4 ) alkyl ester.
- fatty acid- (C 3. -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 -Ci 8 -fatty acid(s).
- the fatty acid- (C 1 -C4) alkyl ester is derived from a vegetable oil.
- vegetable oils examples include olive, peanut, corn, cottonseed, rapeseed, soybean, linseed, castor, coconut, palm, peanut, safflower, sesame, sunflower and tallow oils.
- C 4 ) alkyl ester may be methyl, ethyl, propyl and butyl
- Methyl and ethyl are, however, preferable, methyl being especially preferable.
- rapeseed oil is common in for instance Sweden, this vegetable oil represents a cheap and easily available raw material for the ester referred to.
- the methyl ester of rapeseed oil is an easily available commercial product, that can be directly used in the lubricant composition according to the present invention. Apart from the fact that said methyl ester is cheap and easily available, it has also been found to impart outstanding properties (lubricity, combustibility, etc.) to the lubricant composition, as will be presented below in the experimental part of the description.
- Methods for the esterification of rapeseed oil are also known per se and can be utilized for the manufacture of said ester. Similar methods could be used for other alkyl esters and other vegetable oils. As prior art in this connection reference can be made to US 5,713,965.
- 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.
- 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 ;
- NPG neopentyl glycol
- TMP trimethylol propane
- PE pentaerythritol
- 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.
- esters are selected from the above-mentioned synthetic polyol and sugar polyalcohol fatty acid esters.
- the present invention it has become possible to replace a considerable proportion of such generally expensive esters with easily available and inexpensive fatty acid- alkylesters without any significant impairment of lubricity properties.
- 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.
- lubricity improvers When utilized, 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.
- 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) .
- 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.
- 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.
- 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, SI was prepared and tested at two different laboratories. At one laboratory said sample SI was also compared with a commercial mineral-oil based two-stroke engine oil, S2, and at the other laboratory sample SI was compared with a commercial, synthetic and biodegradable ester-based two stroke engine oil, S3.
- Another lubricant composition according to the present invention Sll 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 SI and S 11 according to the present invention were prepared by mixing the following components in the following percentages:
- Lubricating base oil 25.0 15.0
- the kinematic viscosities of SI and Sll were 10.40 cSt at 40°C and 3.15 cSt at 100°C (SI), and 7.74 cSt at 40°C and 2.65 cSt at 100°C, respectively (Sll) .
- Stroke Chainsaw Engine 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 SI 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) ,
- HVA 232 E-tech scrub cutter was developed to sort out the detergency for two-stroke oils at low engine temperatures.
- the test procedure is chosen to create a high rpm range at low load.
- the HVA 232 E- tech during these conditions has a rather high amount of backflow from the cylinder down into the transfer ducts, it creates tough conditions for the oil in the crankcase . More specifically the test includes the following: After a 15 min braking in phase the carburettor H- needle is set to give:
- the setting is done with a muffer without any catalytic converter.
- a Cat- muffler is used.
- the test cycle has the following sequence: 2s full throttle > 3s idle.
- the only load is the inertia from a 4 -egged grass-cutter.
- the L- needle is set to give max 12 000 (+/-500) r/min.
- the lowest speed normally lies around 6 OOOr/min.
- the novel lubricant composition according to the present invention works extremely well in two-stroke engines and matches currently used commercial two-stroke engine oils which are mineral oil-based or synthetic ester-based. Furthermore, as has been said above, the main components of the novel lubricant composition are readily biodegradable and derivable from renewable sources as well as much cheaper than currently used biodegradable synthetic ester products. In addition thereto, its low viscosity generally means advantages within this technical field.
