Definitions
- the present invention relates to a lubricating oil composition used in an internal combustion engine such as a diesel engine or a gasoline engine.
- An important problem in diesel engines has been how to reduce environment pollution caused by such emission gas components as particulate matters (PM) and NO x .
- An effective solution is to mount such an exhaust purifying device as a particulate filter or an exhaust purifying catalyst (oxidization or reduction catalyst) on an automobile.
- an exhaust purifying device as a particulate filter or an exhaust purifying catalyst (oxidization or reduction catalyst)
- soot adhered to the particulate filter can be eliminated by oxidation or combustion.
- the filter may be clogged by metal oxides, phosphoric salts, sulfate salts, carboxylate salts and the like that are generated by combustion.
- the used engine oil is partially combusted to be exhausted as exhaust gas. Accordingly, the less metal components and sulfur components are contained in the lubricating oil, the more preferable the lubricating oil becomes.
- phosphorus components and sulfur components in the lubricating oil are required to be reduced.
- the content of sulfate ash content is 1.0 weight% or less
- the content of sulfur content is 0.3 weight% or less
- the content of molybdenum is 100 ppm or more (see, for instance, document 1: JP-A-2002-060776 ).
- the lowering of the viscosity of the engine oil may cause portions of the engine to be more easily worn.
- additives such as friction modifiers and extreme pressure agents are added to the engine oil so as to reduce friction damages and wear of the engine entailed by lowered viscosity of the engine oil.
- the extreme pressure agents typically used are phosphorus-containing compounds.
- the phosphorus-containing compounds are known to degrade the catalysts for purifying exhaust gas, the content of the phosphorus-containing compounds in the engine oil is preferably reduced as much as possible. When this is applied, however, it may become difficult to maintain the wear prevention of the engines for a long time, so that a method of maintaining the wear prevention is required.
- engine oil compositions are formed by adding mineral oil or synthetic oil with boron compound derivatives of alkenylsuccinimide, organic molybdenum compounds, specific alkylthiadiazole and specific fatty acid ester (see, for instance, document 2: JP-A-11-269476 ).
- succinimide having a specific structure is used as ashless dispersants in place of or in combination with metal-based detergents (see, for instance, document 4: JP-A-2001-226381 , document 5: JP-A-2001-247623 ).
- Such ashless dispersants can finely disperse the diesel soots generated during the combustion and sludge generated by oxidation degradation of the engine oil and can prevent these diesel soots and sludge from adhering to the engine parts, thereby enhancing detergency for the pistons.
- An object of the invention is to provide a lubricating oil composition for use in internal combustion engines such as gasoline engines, diesel engines and gas engines, the lubricating oil composition capable of maintaining such a high level of friction modification as exhibited when the composition is new oil for a long time even when contents of metal contents and phosphorus contents are suppressed to lower levels, and also capable of maintaining such friction modification even when diesel soots are mixed in a diesel engine.
- lubricating oil compositions for internal combustion engines as follows are provided:
- composition contains: base oil; (A) a boronated product of a succinimide compound; (B) molybdenum dithiocarbamate (hereinafter may also be referred to as “MoDTC”); and (C) zinc dialkyldithiophosphate (hereinafter may also be referred to as "ZnDTP”).
- base oil a boronated product of a succinimide compound
- MoDTC molybdenum dithiocarbamate
- ZnDTP zinc dialkyldithiophosphate
- mineral oil and/or synthetic oil is used for the base oil of the composition.
- the mineral oil and synthetic oil are not particularly limited but may be suitably selected from any mineral oil and synthetic oil that have been conventionally used as base oil of the lubricating oil for internal combustion engines.
- Examples of the mineral oil are mineral oil refined by processing lubricating oil fractions by at least one of solvent-deasphalting, solvent-extracting, hydrocracking, solvent-dewaxing, catalytic-dewaxing and hydrorefining (the lubricating oil fractions are obtained by vacuum-distilling atmospheric residual oil obtained by atmospherically distilling crude oil) and mineral oil manufactured by isomerizing wax and GTL (gas-to-liquid) WAX.
- examples of the synthetic oil are polybutene, polyolefin ( ⁇ -olefin homopolymer or copolymer such as ethylene- ⁇ -olefin copolymer), various esters (such as polyol ester, diacid ester and phosphoric ester), various ethers (such as polyphenylether), polyglycol, alkylbenzene, alkyl naphthalene and the like.
- polyolefin and polyol ester are particularly preferable in perspective of viscosity characteristics, solubility of additives and compatibility with seal rubber.
- one of the above mineral oil may be singularly used or a combination of two or more thereof may be used as the base oil.
- one of the above synthetic oil may be singularly used or a combination of two or more thereof may be used.
- a combination of at least one of the above mineral oil and at least one of the above synthetic oil may be used.
- kinematic viscosity of base oil at 100 degrees C is preferably 2 to 30 mm 2 /s, more preferably 3 to 15 mm 2 /s, further more preferably 4 to 10 mm 2 /s.
- kinematic viscosity at 100 degrees C is 2 mm 2 /s or more, evaporation loss is small.
- the kinematic viscosity at 100 degrees C is 30 mm 2 /s or less, power loss due to viscosity resistance is not so large, thereby improving fuel efficiency.
- the base oil oil whose %CA measured by a ring analysis is 3.0 or less and whose sulfur content is 50 ppm by mass or less is preferably usable.
- the %CA measured by the ring analysis means a proportion (percentage) of aromatic content calculated by the n-d-M ring analysis method.
- the sulfur content is measured based on Japanese Industrial Standard (hereinafter referred to as JIS) K 2541.
- the base oil whose %CA is 3.0 or less and whose sulfur content is 50 ppm by mass or less exhibits favorable oxidation stability. Such base oil can restrict an increase of acid number and a generation of sludge, thereby providing a lubricating oil composition that is less corrosive to metal.
- the %CA is more preferably 1.0 or less, much more preferably 0.5 or less while the sulfur content is more preferably 30 ppm by mass or less.
- viscosity index of the base oil is preferably 70 or more, more preferably 100 or more, much more preferably 120 or more. In the base oil whose viscosity index is 120 or more, a viscosity change due to temperature change is small.
- the component (A) used in the aspect of the invention is a boronated product of a polyalkenyl succinimide compound represented by the following formula (1).
- the polyalkenyl succinimide compound is obtained by reacting (a) succinimide or its anhydride substituted by a polyalkenyl group having a number average molecular weight of 500 to 5000 with (b) polyalkylene polyamine of which mol% or more of the entirety contains a piperazinyl ring structure at its terminal.
- R 1 represents a polyalkenyl group having a number average molecular weight of 500 to 5000
- R 2 , R 3 , R 4 and R 5 each independently represent hydrogen or an alkyl group having 1 to 3 carbon atoms
- q represents an integer of 2 to 4
- n represents an integer of 0 to 3
- r represents an integer of 2 to 4
- A represents an amino group or a group having the same piperazinyl ring structure as the terminal of the polyalkylene polyamine.
- the number average molecular weight of the polyalkenyl group is less than 500 in the component (a)
- the boronated product of the succinimide compound represented by the formula (1) may not be sufficiently soluble in the base oil of the lubricating oil.
- the number average molecular weight of the polyalkenyl group is more than 5000, the polyalkenyl succinimide compound may have high viscosity, thereby deteriorating the handleability. Accordingly, the number average molecular weight of the polyalkenyl group is preferably 500 to 5000, more preferably 800 to 3000.
- the polyalkenyl group having such a molecular weight a polymer or a copolymer of monoolefin and diolefin having 2 to 16 carbon atoms is typically used.
- the monoolefin are ethylene, propylene, butene, butadiene, decene, dodecene, hexadecene and the like.
- butene is particularly preferable in the aspect of the invention because of its enhanced high-temperature detergency for the engine parts and its easy availability.
- a polybutenyl group (a polymer of the butene) are also preferable.
- the polyalkenyl-substituted succinic acid or its anhydride is obtainable by reacting a substance such as polybutene having the molecular weight equivalent to that of the polyalkenyl group with a substance such as maleic anhydride by a known method.
- the polyalkylene polyamine as the component (b) may be polyalkylene polyamine entirely having a piperazinyl ring structure at its terminal, or may alternatively be a mixture of polyalkylene polyamine having a piperazinyl ring structure at its terminal and polyalkylene polyamine having no ring structure at its terminal.
- the content of the polyalkylene polyamine having a piperazinyl ring structure at its terminal is less than 5 mol%, the high-temperature detergency and oxidation stability may become insufficient.
- the content is 10 mol% or more or 20 mol% or more, the high-temperature detergency and oxidation stability are enhanced.
- the upper limit on the content of the polyalkylene polyamine having a piperazinyl ring structure at its terminal is preferably 95 mol% or less, more preferably 90 mol% or less.
- the content of the polyalkylene polyamine having a ring structure at its terminal is preferably 5 to 95 mol%, more preferably 10 to 90 mol%.
- the terminal ring structure of the polyalkylene polyamine having a piperazinyl at its terminal is represented by a formula (1') where both p1 and p2 are 2.
- a representative example of the polyalkylene polyamine having this ring structure at its terminal is aminoalkyl piperazine having a piperazinyl structure at its terminal such as aminoethyl piperazine, aminopropyl piperazine, aminobutyl piperazine, amino(diethylenediamino) piperazine, amino(dipropyldiamino) piperazine and the like.
- aminoethyl piperazine is particularly preferable in view of its easy availability.
