Definitions

  • This invention relates to lubricating oil compositions which exhibit marked reduction in engine carbon deposits. More particularly, this invention is directed to ashless lubricating oil compositions which are adapted for use in diesel engines and which contain high molecular weight ashless dispersants, oil soluble antioxidants and organo-sulfur anti-corrosion agents.
  • zinc dihydrocarbyl dithiophosphates perform multiple functions in the motor oil, namely, oxidation inhibition, bearing corrosion inhibition, and extreme pressure/antiwear protection for the valve train.
  • U.S. Patent 4,147,640 relates to lubricating oils having improved antioxidant and antiwear properties which are obtained by reacting an olefinic hydrocarbon having from 6 to 8 carbon atoms and about 1 to 3 olefinic double bonds concurrently with sulfur and hydrogen sulfide and thereafter reacting the resulting reaction intermediate with additional olefin hydrocarbon.
  • These additives are disclosed to be generally used in conjunction with other conventional oil additives such as overbased metal detergents, polyisobutenylsuccinimide dispersants, and phenolic antioxidants. While it is disclosed that the amount of the zinc additive can be greatly reduced, giving a "low ash” or "no ash” lubricant formulation, it is apparent the patentee was referring to Zn-derived ash, and not total SASH levels.
  • U.S. Patent 4,330,420 relates to low ash, low phosphorus motor oils having improved oxidation stability as a result of the inclusion of synergistic amounts of dialkyldiphenylamine antioxidant and sulfurized polyolefin. It is disclosed that the synergism between these two additives compensates for the decreased amounts of phosphorus in the form of zinc dithiophosphate.
  • the fully formulated motor oils are said to comprise 2 to 10 wt.% of ashless dispersant, 0.5 to 5 wt.% of recited magnesium or calcium detergent salts (to provide at least 0.1% of magnesium or calcium), from 0.5 to 2.0 wt.% of zinc dialkyldithiophosphate; from 0.2 to 2.0 wt.% of a dialkyldiphenolamine antioxidant; from 0.2 to 4 wt.% of a sulfurized polyolefin antioxidant; from 2 to 10 wt.% of a first ethylene propylene VI improver; from 2 to 10 wt.% of a second VI improver consisting of methacrylate terpolymer, and the balance baseoil.
  • U.S. Patent 4,639,324 discloses that metal dithiophosphate salts, while useful as antioxidants, are a source of ash, and discloses an ashless antioxidant comprising a reaction product made by reacting at least one aliphatic olefinically unsaturated hydrocarbon having from 8 to 36 carbons concurrently with sulfur and at least one fatty acid ester to obtain a reaction intermediate which is then reacted with additional sulfur and a dimer of cyclopentadiene or lower C1 to C4 alkyl substituted cyclopentadiene dimers.
  • additives in lubricating compositions are generally used in conjunction with other conventional oil additives such as neutral and overbased calcium or magnesium alkaryl sulfonates, dispersants and phenolic antioxidants. It is disclosed that when using the additives of this invention, the amount of the zinc additive can be greatly reduced giving a "low ash” or "no ash” lubricant formulation. Again, it is apparent that the patentee was referring to Zn-derived ash, and not to total SASH.
  • Metal detergents have been heretofore employed in motor oils to assist in controlling varnish formation and corrosion, and to thereby minimize the adverse impact which varnish and corrosion have upon the efficiency of an internal combustion engine by minimizing the clogging of restricted openings and the reduction in the clearance of moving parts.
  • U.S. Patent 4,089,791 relates to low ash mineral lubricating oil compositions comprising a mineral oil base and minor amounts of an overbased alkaline earth metal compound, a zinc dihydrocarbyl dithiphosphate (ZDDP) and a substituted trialkanolamine compound, wherein at least 50% of the ZDDP compounds consists of zinc dialkaryl dithiophosphates, in order to provide a formulated motor oil which will pass the MS IIC Rust Test and the L-38 Bearing Weight Loss Test.
  • ZDDP zinc dihydrocarbyl dithiphosphate
  • the patent illustrates three oil formulations, containing overbased calcium detergent, ZDDP, trialkanolamine and unspecified conventional lubricating oil additives to provide viscosity index improvement, antioxidant, dispersant and anti-foaming properties.
  • the illustrated formulations each had about 0.66 wt.% SASH levels, based on the reported Ca and Zn concentrations. No diesel motor oil formulations are illustrated.
  • U.S. Patent 4,153,562 relates to antioxidants, which are disclosed to be particularly useful for compounded lubricating oils that are intended for heavy duty use in automotive crankcase formulations of relatively low ash content, wherein the antioxidants are prepared by the condensation of phosphorodithioates of alkylphenol sulfides with unsaturated compounds such as styrene.
  • the antioxidants are exemplified at levels of from 0.3 to 1.25 wt.% in lube oil compositions (Example 3) which also contain about 2.65 wt.% (a.i.) borated polyisobutenylsuccinimide dispersant, about 0.06 wt.% Mg as overbased magnesium sulfonate detergent inhibitor, and about 0.10 wt.% Zn as zinc dialkyldithiophosphate antiwear agent (containing mixed C4/C5 alkyl groups).
  • lube oil compositions Example 3 which also contain about 2.65 wt.% (a.i.) borated polyisobutenylsuccinimide dispersant, about 0.06 wt.% Mg as overbased magnesium sulfonate detergent inhibitor, and about 0.10 wt.% Zn as zinc dialkyldithiophosphate antiwear agent (containing mixed C4/C5 alkyl groups).
  • U.S. Patent 4,165,292 discloses that overbased metal compounds provide effective rust inhibition in automotive crankcase lubricants and that in the absence of overbased additives, as in ashless oils, or when such additives are present in reduced amounts, as in "low ash” oils, rusting becomes a serious problem. Such rust requirements are evaluated by ASTM Sequence IIC engine-tests.
  • the Patent discloses a non-ash forming corrosion or rust inhibitor comprising a combination of an oil-soluble basic organic nitrogen compound (having a recited basicity value) and an alkenyl or alkyl substituted succinic acid having from 12 to 50 carbon atoms.
  • the basic organic nitrogen compound and the carboxylic acid compound are required to be used together to achieve the desired rust-inhibiting properties. It is disclosed that best results are achieved by use of an excess of amine over that required to form the neutral salts of the substituted succinic acid present.
  • U.S. Patent 4,502,970 relates to improved crankcase lubricating oil compositions containing lubricating oil dispersant, overbased metal detergent, zinc dialkyldithiophosphate antiwear additive and polyisobutenylsuccinic anhydride, in recited amounts.
  • Exemplary lubricating oil formulations are disclosed containing 3 wt.% polyisobutenylsuccinimide dispersant, polyisobutenylsuccinic anhydride, overbased metal sulfonate or overbased sulfurized phenate detergents and zinc dialkyldithiophosphate antiwear agents, in base oil, in amounts of 3.0, 3.0, 2.0, 1.0 and 91.0 wt.%, respectively.
  • European Patent 24,146 relates to lubricating oil compositions containing copper antioxidants, and exemplifies copper antioxidants in lubricating oil compositions also containing 1.0 wt. % of a 400 TBN magnesium sulphonate (containing 9.2 wt. % magnesium), 0.3 wt. % of a 250 TBN calcium phenate (containing 9.3 wt. % of calcium) and a zinc dialkyldithiophosphate in which the alkyl groups or a mixture of such groups having between 4 and 5 carbon atoms and made by reacting phosphorous P2S5 with a mixture of about 65% isobutyl alcohol and 35% of amyl alcohol, to give a phosphorous level of 1.0 wt. % in lubricating oil composition.
  • top land deposits which are believed to contribute to increased oil consumption due to two phenomena: (1) these deposits decrease the amount of blow-by flowing downwardly past the top land, which results in a decreased gas loading behind the top ring of the piston, which in turn leads to higher oil consumption; and (2) increased bore polishing of the piston cylinder liner by the top land deposits which in turn contributes to higher oil consumption by migration of the oil into the firing chamber of the cylinder along the polished bore paths. Therefore, the Paper concluded that reduced ash in the oil should be sought to reduce top land deposits, and hence oil consumption.
  • This 1983 Schetelich paper reports formulation of 2 test oils, each containing about 1% SASH and having TBN levels of 10 and 9, respectively, wherein each formulated oil contained overbased metal detergent together with a zinc-source.

  • the top land clearance can be less than the dimensions given above (e.g., less than 0.005 inch), if such lesser distances do not result in undesired contact of the top land portion of the piston with the cylinder wall liner during operation of the engine, which is undesirable due to the resultant damage to the liner.
  • the height of the top land (that is, the vertical distance, as measured along the cylinder wall liner, from the bottom of the top land to the top of the top land) is from 0.1 to about 1.2 inch, which is generally from 0.8 to 1.2 inch for 4-cycle diesel engines and from 0.1 to 0.5 inch for 2-cycle diesel engines.
  • the design of diesel engines and such pistons having such tight top lands is within the skill of the skilled artisan and need not be further described herein.
  • oil soluble is intended to mean that the additive or material identified is soluble, dissolvable in oil with the aid of a suitable solvent, or stably dispersible.
  • oil soluble does not necessarily indicate that the additive or material is soluble (or dissolvable, miscible or capable of being suspended) in oil in all proportions. It does mean, however, that the additives, for instance, are soluble (or stably dispersible) in oil to an extent sufficient to exert their intended effect in the environment in which the oil is employed.
  • the additional incorporation of other additives may also permit incorporation of higher levels of a particular polymer adduct hereof, if desired.
