Definitions

  • the present invention relates to new uses of corrosion inhibitors in fuels and lubricants.
  • Corrosion inhibitors are common additives in fuels and lubricants, often based on acid-containing structures, e.g. Dimer fatty acids.
  • a disadvantage of these corrosion inhibitors is that they tend to precipitate, especially in the presence of calcium ions, and as a result their corrosion-inhibiting action is reduced.
  • the deposits formed by these precipitates may also affect the operation of engines, engine components or parts of the fuel system.
  • EP 235868 describes corrosion-inhibiting mixtures of hydrocarbon-substituted succinic acid derivatives, which are connected to one another via ring structures, and long-chain substituted polyamines.
