Definitions

  • the emulsion composition comprises: (a) a first phase comprising:
  • the filterability test as described above is replaced by measuring the rheological properties of the metal base during dewatering.
  • the rheological properties are measured using a Bohlin Instuments GeminiTM Rheometer.
  • the methodology of the test is described in the Example section and the results obtained are the length of time required for the formation of a filter cake.
  • a filter cake forms when the metal base aggregates.
  • the methodology of the Bohlin Instuments GeminiTM Rheometer required the metal base to be suspended in water rather than in the emulsion composition.
  • the GeminiTM Rheometer is operated at ambient temperature.
  • the length of time required for the metal base to form of a filter cake is at least 60 seconds (s), or at least 65 s or at least 70 s.
  • the emulsion composition when employed in an internal combustion engine in several embodiments has a total base number (TBN) of at least 1 , at least
  • the liquid fuel is a gasoline, and in another embodiment, the liquid fuel is a gasohol (i.e., gasoline alcohol mixture), and in another embodiment the liquid fuel is a diesel fuel.
  • the hydrocarbon fuel includes a hydrocarbon prepared by a gas to liquid process, for example, Fischer-Tropsch.
  • the nonhydrocarbon fuel includes an oxygen containing composition, often referred to as an oxygenate.
  • the nonhydrocarbon fuel includes a monohydric alcohol, an ether, a ketone, an ester of a carboxylic acid, a nitroalkane, or a mixture thereof.
  • This first and/or second polyisobutene-substituted succinic anhydride may be characterized by at least 1.3, in another embodiment 1.3 to 2.5, and in another embodiment 1.7 to 2.1 succinic groups per equivalent weight of the polyisobutene substituent.
  • the first and/or second hydrocarbyl-substituted carboxylic acid acylating agent may be a polyisobutene-substituted succinic anhydride, the polyisobutene substituent having a number average molecular weight of 700 to 1300, and in another embodiment 800 to 1000.
  • a second phase comprises: (i) a metal base
  • the emulsion composition optionally further includes at least one other performance additive.
  • the other performance additive compounds include a metal deactivator, a detergent, a dispersant, an extreme pressure agent, an antiwear agent, an antioxidant, a friction modifier, a corrosion inhibitor, a foam inhibitor, a demulsifiers, a pour point depressant, a seal swelling agent or mixtures thereof.
  • the emulsion composition further contains a detergent, a dispersant or mixtures thereof.
  • wt % 0.01 wt % to 20 wt %, in another embodiment 0.1 wt % to 15 wt % and in yet another embodiment 0.5 wt % to 10 wt % of the emulsion composition.
  • the other performance additives may be present, it is common for the other performance additives to be present in different amounts relative to each other.
  • the invention further comprises at least one dispersant derived from polyisobutylene, an amine and zinc oxide to form a polyisobutylene succinimide complex with zinc.
  • the polyisobutylene succinimide complex with zinc may be used alone or in combination.
  • the dispersant is borated using a variety of agents selected from the group consisting of the various forms of boric acid (including metaboric acid, HBO 2 , orthoboric acid, H 3 BO 3 , and tetraboric acid, H 2 B 4 O 7 ), boric oxide, boron trioxide, and alkyl borates.
  • the borating agent is boric acid which may be used alone or in combination with other borating agents.
  • corrosion inhibitors including octylamine octanoate, condensation products of dodecenyl succinic acid or anhydride and a fatty acid such as oleic acid with a polyamine
  • metal deactivators including derivatives of benzotriazoles, 1 ,2,4-triazoles, benzimidazoles, 2- alkyldithiobenzimidazoles or 2-alkyldithiobenzothiazoles
  • foam inhibitors including copolymers of ethyl acrylate and 2-ethylhexylacrylate and optionally vinyl acetate
  • antioxidant include a diphenylamine, a hindered phenol, a molybdenum dithiocarbamates or a sulphurised olefin
