Definitions

  • the invention relates to derivatives of dicarboxylic acids as additives in low-leaded or unleaded automobile gasoline that minimize wear of exhaust valve seats in automobile engines that are not designed for internal combustion of unleaded automobile gasoline.
  • leaded gasoline for as long as such automobile engines will be in operation. However, in this case production of leaded gasoline cannot be terminated with resulting consequences to the environment.
  • the derivatives of dicarboxylic acids as additives to automobile gasolines according to this invention can contain also an auxiliary component, such as an organic solvent, preferably of aromatic type.
  • Suitable solvents are toluene, xylene, aromatic hydrocarbons with 9 to 13 carbon atoms in molecule or their technical blends, eg reformate of heavy gasoline, fractions from reformate having boiling point in the range from 75 °C to 250 °C, fractions from pyrolysis gasoline with a similar distillation range.
  • Aromatic hydrocarbons content in such blends is usually above 25 % wt.
  • additives based on dicarboxylic acids according to the invention are added to automobile gasoline in concentration from 0.025 wt. to 1.1 % wt. If the additive according to the invention contains an auxiliary component which is the above specified organic solvent, the amount of this blend is so selected that the concentration of the effective component is in the above specified range.
  • the additive according to this invention can be added to gasoline either directly at the stage of automobile gasoline preparation in a refinery (primary addition) or it is possible to add this additive to the finalized gasoline at the stage of its consumption or distribution, e.g. in filling stations (secondary addition).
  • the secondary addition of this additive according to this invention is preferable especially in such cases when automobile gasoline is produced without its content.
  • the additive of this composition was dissolved in an aromatic solvent having boiling point between 140 and 190°C to make its handling easier so that the resulting solution contained 10 % of the effective component.
  • the evaluation has shown that the additive according to the invention provides perfect protection to exhaust valve seats in all automobiles tested to their wear during combustion of unleaded gasoline.
  • the additive has negative influence on any function of a spark-ignition engine and on its life expectancy.
  • This additive is harmless to catalytic systems for exhaust gas purification and does not deteriorate emissions of spark-ignited engine.
