Definitions

  • the present invention relates to a fuel composition containing a special low-alkanol-containing gasoline fuel in a larger amount and selected gasoline fuel additives in a smaller amount.

  • valve seat wear-resistant additives based on alkali or alkaline earth metal compounds have been developed.
  • Modern gasoline engines require fuels with a complex property profile for trouble-free use, which can only be guaranteed in combination with appropriate gasoline additives.
  • Such gasoline fuels generally consist of a complex mixture of chemical compounds and are characterized by physical quantities.
