Definitions
- the invention relates to synergistic gasoline fuel additive compositions with synergistic performance in keeping the intake system clean and with them additized fuels for gasoline engines.
- Carburetors and intake systems of gasoline engines are increasingly contaminated by contaminants caused by dust particles from the air, unburned hydrocarbon residues from the combustion chamber and the crankcase ventilation gases passed into the carburetor.
- the first additive generation could only prevent the formation of deposits in the intake system, but not remove existing deposits, whereas the modern additives of the second generation can do both (keep-clean and clean-up effect), in particular also because of their excellent thermal stability in zones of higher temperature, namely on the inlet valves.
- Such detergents which can originate from a large number of chemical substance classes, such as, for example, polyalkenamines, polyetheramines, polybutene-Mannich bases or Polybutene sucinimides are generally used in combination with carrier oils and some other additive components, such as corrosion inhibitors and demulsifiers.
- the carrier oils have a solvent or washing function in combination with the detergents.
- Carrier oils are usually high-boiling, viscous, thermostable liquids that coat the hot metal surface and thereby prevent the formation or deposition of contaminants on the metal surface.
