Definitions

  • the present invention relates to a fuel composition containing a special gasoline fuel in a larger amount and selected gasoline additives in a smaller amount.
  • Carburetors and intake systems of gasoline engines are increasingly contaminated with contaminants caused by dust particles from the air, unburned hydrocarbon residues from the combustion chamber and the crankcase ventilation gases that are led into the carburetor.
  • valve seat wear-inhibiting 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 petrol generally consist of a complex mixture of chemical compounds and are characterized by physical quantities.
  • the interaction between gasoline fuels and the corresponding additives is, however, in need of improvement in the known fuel compositions with regard to the cleaning or keeping-clean effect and the valve seat wear-inhibiting effect.
  • the object of the present invention was therefore to find a more effective gasoline / gasoline / gasoline additive composition.
