Definitions
- This invention relates to multigrade lubricating oil compositions that, in particular, give enhanced performance in diesel engine ring-sticking tests.
- Lubricating oil compositions for the crankcase of internal combustion engines are well-known and it is also well-known for them to contain additives (or additive components) to enhance their properties and performance.
- the invention is an SAE 0W-30 or 5W-30 or 5W-20 multigrade lubricating oil composition having a Noack volatility of less than 15, such as less than 13, preferably less than 11, preferably no lower than 4 or 5, % mass loss according to CEC L-40-A-93; said composition comprising, or being made by admixing, a major amount of
- the invention is a method of lubricating a compression-ignited internal combustion engine comprising operating the engine and lubricating the engine with a lubricating oil composition according to the first aspect of the invention.
- the invention is a method of reducing the ring-sticking tendencies of a compression-ignited internal combustion engine comprising adding to the engine a lubricating oil composition according to the first aspect of the invention.
- the invention is a combination comprising the crankcase of a compression-ignited engine and a lubricating oil composition according to the first aspect of the invention for lubricating the crankcase.
- the invention also provides the product obtained or obtainable as a result of any reaction between the various additive components of the composition or concentrates, essential as well as customary and optimal, under the conditions of formulation, storage or use:
- Multigrade lubricants perform over wide temperature ranges. Typically, they are identified by descriptors such as SAE 10W-30 or SAE 5W-30.
- the first number in the multigrade descriptor is associated with a safe cranking temperature (e.g., -20° C) viscosity requirement for that multigrade oil as measured by a cold cranking simulator (CCS) under high shear rates (ASTM D5293).
- CCS cold cranking simulator
- ASTM D5293 high shear rates
- lubricants that have low CCS viscosities allow the engine to crank more easily at lower temperatures and thus improve the ability of the engine to start at those ambient temperatures.
- Multiviscosity -grade oils are designed to operate over wide temperature ranges and are identified by descriptors such as SAE 10W-30 or SAE 5W-30,. Their properties are defined in the Society of Automotive Engineers document SAE J300. This publication defines multigrades in terms of two criteria: Maximum low temperature cranking and pumping viscosities and Maximum and minimum kinematic viscosities at 100°C and a minimum high-shear viscosity at 150°C and 10 8 s -1 . Low temperature properties define which "W” grade shall be assigned to a lubricant and high temperature properties define the "non W" part of the designation.
- SAE J300 defines a series of W grades with SAE 0W representing the requirements for operation at lowest temperatures.
- SAE 5W, 10W, 15W, 20W and 25W are also defined, these grades are suitable for progressively higher minimum temperature of operation.
- Non-W grades are also assigned a numerical designation, these define a scale of increasing high temperature viscosity. This scale starts with SAE 20 and goes through SAE 30, 40 and 50 to the most viscous grade, SAE 60.
- M-111 fuel economy is as measured in accordance with CEC-L-54-T-96.
- the basestock (sometimes referred to as “base oil”) is an oil of lubricating viscosity and is the primary liquid constituent of a lubricant into which additives and possibly other oils are blended to produce the final lubricant.
- Basestocks may be categorised in Groups I to V according to the API Engine Oil Licensing and Certification System (EOLCS) API 1509 definitions, which definitions are used to define the basestocks of this invention.
- EOLCS Engine Oil Licensing and Certification System
- the molybdenum may, for example, be used in oxidation states IV, and V, such as known in the art.
- the molybdenum may be present as a cation, but this is not essential.
- molybdenum-containing complexes may be used.
- molybdenum compounds examples include the molybdenum salts of inorganic and organic acids (see, for example, U.S. Patent No. 4 705 641 ), particularly molybdenum salts of monocarboxylic acids having from 1 to 50, preferably 8 to 18, carbon atoms, for example, molybdenum octanoate (preferably 2-ethylhexanoate), naphthenate or stearate; the reaction product of molybdenum trioxide, molybdic acid or an alkali metal salt thereof (or the reaction product of such a molybdenum compound and a reducing agent) and a secondary amine having hydrocarbon groups having 6 to 24 carbon atoms (see EP-A-205 165 ); overbased molybdenum-containing complexes as disclosed in EP-A-404 650 , molybdenum dithiocarbamates and, less preferred because of their phosphorus content, molybdenum dithiophosphates; oil
- Patent Nos 4,995,996 and 4,966,719 particularly the molybdenum xanthates and thioxanthates described in those specifications; and oil-soluble molybdenum and sulfur-containing complexes.
- Specific examples of molybdenum- and sulfur-containing complexes are those prepared by reacting an acidic molybdenum compound with a basic nitrogen-containing substance and then with a sulfur source (see, for example, GB-A-2 097 422 ), and those prepared by reacting a triglyceride with a basic nitrogen compound to form a reaction product, reacting the reaction product with an acidic molybdenum compound to form an intermediate reaction product, and reacting the intermediate reaction product with a sulfur-containing compound (see, for example, GB-A-2 220 954 ).
- molybdenum compounds are described in International Patent Application No. PCT/IB97/01656 and comprise a trinuclear molybdenum core, optionally containing non-metallic atoms consisting wholly or partly of sulfur, and bonded thereto ligands capable of rendering the compound oil-soluble or oil-dispersible.
- the compounds may be represented by the general formula Mo 3 S k L p . wherein
- a detergent is an additive that reduces formation of piston deposits, for example high temperature varnish and lacquer deposits, in engines; it normally has acid-neutralising properties and is capable of keeping finely-divided solids in suspension.
- Most detergents are based on metal "soaps", that is metal surfactants or salts of acidic organic compounds.
- Detergents generally comprise a polar head with a long hydrophobic tail, the polar head comprising a metal salt of an acidic organic compound.
- the salts may contain a substantially stoichiometric amount of the metal, in which case they are usually described as normal or neutral salts, and would typically have a total base number or TBN (as may be measured by ASTM D2896) of from 0 to 80.
- TBN total base number
- Large amounts of a metal base can be included by reacting an excess of a metal compound, such as an oxide or hydroxide, with an acidic gas such as carbon dioxide.
- the resulting overbased detergent comprises neutralised detergent as the outer layer of a metal base (e.g. carbonate) micelle.
- Such overbased detergents may have a TBN of 150 or greater, and typically of from 250 to 450 or more.
- the calcium detergents that may be used include oil-soluble neutral and overbased sulfonates, phenates, sulfurized phenates, thiophosphonates, salicylates, and naphthenates.
- Particularly convenient calcium detergents are neutral and overbased calcium sulfonates having a TBN of from 20 to 450 TBN, and neutral and overbased calcium phenates and sulfurized phenates having a TBN of from 50 to 450.
- Sulfonates may be prepared from sulfonic acids, which are typically obtained by the sulfonation of alkyl-substituted aromatic hydrocarbons such as those obtained from the fractionation of petroleum or by the alkylation of aromatic hydrocarbons. Examples included those obtained by alkylating benzene, toluene, xylene, naphthalene, diphenyl or their halogen derivatives such as chlorobenzene, chlorotoluene and chloronaphthalene.
- the alkylation may be carried out in the presence of a catalyst using alkylating agents having from 3 to more than 70 carbon atoms.
- Alkaryl sulfonates usually contain from 9 to 80 or more, preferably from 16 to 60, carbon atoms per alkyl-substituted aromatic moiety.
- Oil-soluble sulfonates or alkaryl sulfonic acids may be neutralised with oxides, hydroxides, alkoxides, carbonates, carboxylate, sulfides, hydrosulfides, nitrates, borates and ethers of the calcium.
- the amount of calcium compound is chosen having regard to the desired TBN of the final product but typically ranges from about 100 to 220, preferably at least 125, mass %.
- Calcium salts of phenols and sulfurised phenols are prepared by reaction of the phenol with an appropriate calcium compound such as an oxide or hydroxide, and neutral or overbased products may be obtained by methods known in the art.
- Sulfurised phenols may be prepared by reacting a phenol with sulfur or a sulfur - containing compound such as hydrogen sulfide, sulfur monohalide or sulfur dihalide to form products which are generally mixtures of compounds in which two or more phenols are bridged by sulfur-containing bridges.
- Viscosity modifiers impart high and low temperature operability to a lubricating oil.
- Viscosity modifiers that also function as dispersants are also known and may be prepared as described above for ashless dispersants.
- these so-called dispersant viscosity modifiers are functionalized polymers (e.g. interpolymers of ethylene-propylene post-grafted with an active monomer such as maleic anhydride) which are then derivatized with, for example, an alcohol or amine.
- Suitable compounds for use as viscosity modifiers are generally high molecular weight hydrocarbon polymers, including polyesters.
- Oil-soluble viscosity modifying polymers generally have weight average molecular weights of from 10,000 to 1,000,000, preferably 20,000 to 500,000, which may be determined by gel permeation chromatography or by light scattering.
- suitable viscosity modifiers are polyisobutylene, copolymers of ethylene and propylene and higher alpha-olefins, polymethacrylates, polyalkylmethacrylates, methacrylate copolymers, copolymers of an unsaturated dicarboxylic acid and a vinyl compound, interpolymers of styrene and acrylic esters, and partially hydrogenated copolymers of styrene, isoprene, styrene/butadiene, and isoprene/butadiene, as well as the partially hydrogenated homopolymers of butadiene and isoprene and isoprene/divinylbenzene.
- additives may be incorporated into the lubricating oil compositions of the invention, being different from those defined in the invention. They may, for example, include other detergents; rust inhibitors; corrosion inhibitors; pour point depressants; anti-foaming agents; and surfactants. They can be combined in proportions known in the art.
- additives can provide a multiplicity of effects; thus, for example, a single additive may act both as a dispersant and as an anti-oxidant.
- the additives provide less than 50 ppm by mass of chlorine to the composition.
- the use of chlorine-containing additives eg arising from their method of manufacture) must be eliminated or at least controlled.
- additive(s) therefor in the form of concentrates of the additive(s) in a suitable oleaginous, typically hydrocarbon, carrier fluid, e.g. mineral lubricating oil, or other suitable solvent.
- carrier fluid e.g. mineral lubricating oil, or other suitable solvent.
- Oils of lubricating viscosity such as described herein, as well as aliphatic, naphthenic, and aromatic hydrocarbons, are examples of suitable carrier fluids for concentrates.
- Concentrates constitute a convenient means of handling additives before their use, as well as facilitating solution or dispersion of additive in lubricating oil compositions.
- each additive When preparing a lubricating oil composition that contains more than one type of additive, each additive may be incorporated separately - each in the form of a concentrate. In many instances, however, it is convenient to provide a so-called additive "package" (also referred to as an "adpack") comprising two or more additives in a single concentrate.
- a concentrate may contain 1 to 90, such as 10 to 80, preferably 20 to 80, more preferably 20 to 70, mass % active ingredient of the additive or additives.
- Lubricating oil compositions may be prepared by adding to an oil of lubricating viscosity a mixture of an effective minor amount of at least one additive and, if necessary, one or more co-additives such as described hereinafter. This preparation may be accomplished by adding the additive directly to the oil or by adding it in the form of a concentrate thereof to disperse or dissolve the additive. Additives may be added to the oil by any method known to those skilled in the art, either prior to, contemporaneously with, or subsequent to addition of other additives.
- the lubricating oil compositions may be used to lubricate mechanical engine components, particularly an internal combustion, such as a compression-ignited engine, by adding the lubricating oil thereto.
- mechanical engine components particularly an internal combustion, such as a compression-ignited engine
- compression-ignited engine are those developed in recent years where the top ring groove temperature may exceed 150°C due to increases in specific power output to around 40 kW/litre or greater. These engines are more prone to suffer from ring-sticking problems in their operation.
- concentrates When concentrates are used to make the lubricating oil compositions, they may for example be diluted with 3 to 100, e.g. 5 to 40, parts by mass of oil of lubricating viscosity per part of the concentrate.
- each additive is typically blended into the base oil in an amount which enables the additive to provide its desired function.
- Representative effective amounts of such additives, when used in crankcase lubricants, are listed below. All the values listed herein are stated as mass per cent active ingredient, unless otherwise indicated.
- the final composition may contain from 5 to 25, preferably 5 to 18, typically 10 to 15, mass % of the concentrate, the remainder being oil of lubricating viscosity.
- Adpacks Four additive packages (or "adpacks") were prepared by methods known in the art and identified as Packages 1, A, 2 and B. The packages were identical except that Packages 1 and 2 contained molybdenum (in the same concentrations) and Packages A and B did not, and that Packages 1 and A contained less dispersant than Packages 2 and B, Packages 1 and A having identical dispersant-concentrations, and Packages 2 and B having identical dispersant-concentrations.
- SAE 0W-30 lubricating oil composition having the following characteristics, wherein each oil is identified by the same reference numeral or letter as the package from which it was blended.
- OIL 1 A 2 B Noack Volatility 10.7 10.6 11 10.6 Cl-content (ppm) 26 26 26 26 Mo-content (ppm) 100 0 100 0 Surfactant content (mmoles/Kg) 14.2 14.2 14.2 14.2 Dispersant content (mass %) 2.6 2.6 3.5 3.5
- OIL 1 A 2 B merits 1 65 46 68 56 ring stick 2 (average) 0 2.63 0 0.63 ring stick 3 (maximum) 0 5.0 0 2.5 Each test was run to its full duration, ie not terminated prematurely
- an SAE 5W-30 lubricating oil composition (Oil 3) was prepared that contained a trinuclear molybdenum/sulfur thiocarbamate additive providing 300 ppm by mass of elemental molybdenum, a diphenyl-amine anti-oxidant (0.35 mass %), and a hindered phenol antioxidant (1.1 mass %). Oil 3 possessed other properties falling within those of the compositions of the first aspect of the invention.
- Oil 3 was tested in the API Seq III test, but carried out for twice the stipulated length of time (128 hours as opposed to 64 hours).
- the stipulated test is concerned with piston cleanliness, cam and lifter wear, and viscosity growth in the oil. Doubling the duration of the tests increases its severity: under these conditions, the viscosity growth usually becomes the limiting factor and hence control of oil viscosity by use of additives becomes critical.
