Definitions

  • the present invention relates to lead compound free high-octane fuel compositions for internal combustion engines with spark ignition, prepared by using hydrocarbon fuels and anti-knock additive.
  • US-A-2810737 describes alpha-hydroxyalkyl ferrocene derivatives and their use as anti-knock agents in spark ignition fuels.
  • m-nitrocinnamoylferrocene and o-chlorocinnamoylferocene are produced from ferrocene in a number of stages with a low yield and all characterized with a low solubility rate in the fuel composition.
  • the present invention provides a hydrocarbon based fuel composition suitable for spark ignition internal combustion engines, which comprises 0.001% - 0.02% by weight of
  • the hydrocarbon composition comprises: aromatic hydrocarbone 54 to 56 percent by weight. normal alkanes 12 to 13 percent by weight. isoalkanes 29 to 31 percent by weight. naphtheness 1 to 2 percent by weight.
  • Such a composition has fractions as follows: initial boiling point: 60 grad.C distillation fraction of 10 percent; 83 grad.C distillation fraction of 50 percent: 114 grad.C distillation fraction of 90 percent: 156 grad.C distillation fraction of 96 percent: 190 grad.C density p20/4 being 0.7687 g/cm 3 and motor octane number being 80.
  • the present invention further provides the use of as an anti-knock additive suitable for fuels.
  • the fuel composition octane number was determined on the plant UIT-85 by a motor method according to OMEA Standard 2243-80.
  • the plug operation-to-failure time was determined on the single cylinder compartment of the engine ZIL-130 at alternative modes covering a wide spectrum of changed parameters such as temperature of cooling liquid, load, ingredients of mixture and lead angle of ignition. The test was carried out by some five-hour cycles.
  • Iron oxide on the sparking plug A11 with an initial gap being 0.64 mm was appreciated by parameters as follows: change of sparking gap, change of the sparking plug weight, iron oxide deposit surface nature on the sparking plug electrodes.
  • the sparking gap was measured by using the projector type SVET with magnification X100 and the iron oxide deposit surface nature was estimated by means of an optical microscope type MIN-8 with magnification X50.
  • the fuel composition was tested by using, as anti-knock additive, a ferrocene derivative corresponding to the prior art (Nos 1. to 6 in the following Table) and a ferrocene derivative in different amounts according to the present invention (Nos. 7 to 10 in the following Table). No.
  • Examples 7 to 10 fuel composition according to the invention indicate that the accumulation of iron oxide deposits up to the equal weight state (50 to 55 mg) proceeds for 25 hours and remains at this level for a long period of the tests.
  • the known prior art fuel composition containing an equivalent amount of iron (458 x 10 -5 percent by weight) in the fuel mixture when the similar amount of iron oxide deposit (50 to 55 mg) for a more extended period of time (35 to 40 hours) leads to a stoppage of the engine (see Examples 1,4).
  • the step of decreasing the content of the anti-knock ferrocene additives by iron to 229 x 10 -5 percent by weight as for the fuel composition according to the invention increases the time to achieve the equal weight state of iron oxide deposit up to a level of 40 hours and to diminish the deposit value in the equal weight state down to 30 to 34 mg (see Example 9).
  • ⁇ -hydroxyisopropyl ferrocene as an anti-knock additive serves to increase the life of sparking plugs without worsening the performances of the engine.
  • ⁇ -hydroxyisopropyl ferrocene in the fuel composition increases by 15 to 20 percent the growth of octane number as compared to m-nitrocinnamoylferrocene and o-chlorocinnamoyl ferrocene at the equivalent content of iron.
  • the lower limit of the use of ⁇ -hydroxyisopropyl ferrocene is 0.001 percent (see Example 10), the upper limit is 0.02 percent (see Example 8) and corresponds to the maximum possible content at which a faultless operation of the engine is provided.
