Definitions

  • This invention concerns a lubricant composition, in particular, a marine diesel cylinder lubricant (MDCL) composition.
  • Marine diesel cylinder lubricant compositions are total loss lubricants and their purpose is to provide a strong oil film between the cylinder liner and the piston rings and to neutralise acids formed by combustion of sulphur compounds in the fuel.
  • Fuels used for diesel engines generally have a high sulphur content (such as, for example, at least 3.5% sulphur), which results in exhaust gases from diesel engines containing large amounts of sulphur oxides (SO x ).
  • SO x sulphur oxides
  • the sulphur oxides react with moisture also present in the exhaust gases to form sulphuric acid which corrodes the engine.
  • Marine diesel cylinder lubricant compositions therefore include overbased metallic detergents to neutralise the sulphuric acid.
  • Commercial marine diesel cylinder lubricant compositions generally have a total base number ('TBN') of at least 70 (as determined using ASTM D2896).
  • Environmental concerns have prompted many areas, such as coastal areas, to require the use of low sulphur fuels, i.e. fuels including less than 1.00% by weight of sulphur, which allows the use of marine diesel cylinder lubricant compositions having lower total base numbers such as, for example, 40. This therefore creates
  • US 4,842,755 discloses a marine diesel cylinder lubricant having a base number of at least 60.
  • the composition includes a borated ashless dispersant, one or more overbased metal compounds and a zinc dialkyl dithiophosphate providing 0.02 to 0.023 wt% (200-230 ppm) of zinc (see claim 1).
  • the specific examples show that increasing the amount of zinc above 230 ppm results in a loss in performance benefits in ring and liner wear.
  • EP1 298 189 discloses lubricating composition
  • a Mo-compound a detergent derived from sulfonate and phenate surfactants and a boron containing dispersant.
  • An aim of the present invention is to provide a marine diesel cylinder lubricant composition having a total base number of at least 35 or more (ASTM D 2896-01), that is suitable for use with both high and low sulphur fuels.
  • a further aim of the present invention is to provide a marine diesel cylinder lubricant composition having a total base number of at least 35 or more (ASTM D 2896-01) that is suitable for use with both high and low sulphur fuels, whilst still providing the required level of protection against corrosive wear when used with a high sulphur fuel.
  • a marine diesel cylinder lubricant composition having a total base number, as determined according to ASTM D2896, of at least 35 or more, and comprising:

  • hydrocracked oils Another class of lubricating oils is hydrocracked oils, where the refining process further breaks down the middle and heavy distillate fractions in the presence of hydrogen at high temperatures and moderate pressures.
  • Hydrocracked oils typically have a kinematic viscosity at 100°C of from 2 to 40, for example from 3 to 15, mm 2 s -1 and a viscosity index typically in the range of from 100 to 110, for example from 105 to 108.
  • the oil may include 'brightstock' which refers to base oils which are solvent-extracted, de-asphalted products from vacuum residuum generally having a kinematic viscosity at 100°C of from 28 to 36 mm 2 s -1 and are typically used in a proportion of less than 40, preferably less than 30, more preferably less than 20, mass %, based on the mass of the composition.
  • 'brightstock' refers to base oils which are solvent-extracted, de-asphalted products from vacuum residuum generally having a kinematic viscosity at 100°C of from 28 to 36 mm 2 s -1 and are typically used in a proportion of less than 40, preferably less than 30, more preferably less than 20, mass %, based on the mass of the composition.

  • a dithiophosphoric acid may be made by reacting mixtures of primary and secondary alcohols.
  • multiple dithiophosphoric acids can be prepared comprising both hydrocarbyl groups that are entirely secondary and hydrocarbyl groups that are entirely primary.
  • any basic or neutral zinc compound may be used but the oxides, hydroxides and carbonates are most generally employed. Commercial additives frequently contain an excess of zinc due to use of an excess of the basic zinc compound in the neutralisation reaction.

  • additives such as pour point depressants, anti-foamants, and/or demulsifiers may be provided, if necessary.
  • 'oil-soluble' or ⁇ oil-dispersable' do not necessarily indicate that the compounds or additives are soluble, dissolvable, miscible or capable of being suspended in the oil in all proportions. These do mean, however, that they are, for instance, soluble or stably dispersible in oil to an extent sufficient to exert their intended effect in the environment in which the oil is employed.
