Definitions

  • the invention relates to the use of an unleaded liquid fuel containing 1 to 100 ppm by weight of ferrocene for operating an Otto engine.
  • the object of the present invention is to reduce the fuel consumption and the exhaust gas emissions when operating an Otto engine with an exhaust gas catalytic converter system for exhaust gas afterburning.
  • gasoline engines equipped with exhaust gas catalytic converter systems for exhaust gas afterburning can be operated with ferrocene-additive fuel with an improved effect of the catalytic converter system.
  • This is preferably a regulated catalyst system, built up on a bulk or monolithic carrier with a coating of a noble metal, an oxidic metal compound or a combination of both.
  • the positive effects of adding ferrocene are achieved by adding ferrocene to the fuel in amounts of 1 to 100, preferably 5 to 20, ppm by weight of ferrocene. Ferrocene is given to the fuel in the amounts required according to the recommended concentration due to its good Solubility added directly with mixing. It is expedient to prepare a concentrate of ferrocene dissolved in liquid fuel (petrol), an alcohol, an ether, an aromatic solvent or mixtures thereof or the like and then to mix the required volume with the fuel to adjust the desired ferrocene concentration.
  • liquid fuel petrol
  • an alcohol an alcohol
  • an ether an aromatic solvent or mixtures thereof or the like
  • Figure 1 documents the increase in OZ demand in the engines of the two test vehicles in comparison. The results are expressed as a pre-adjustment ° crank angle depending on the mileage in km and were measured with the same reference fuel. The results show no significant differences in both engines, but the increase in OZ demand from the 50,000 km mileage for the engine operated with ferrocene is slightly improved.
  • Figure 2 shows the fuel consumption values in the comparison of the two test vehicles, from which a significantly lower consumption of the vehicle operated with ferrocene can be demonstrated.
  • FIG. 8 and FIG. 9 show the pressure curve on a pressure-indicated 1-cylinder engine as a test engine, the family of curves shown in FIG. 8 representing approximately 30 combustion processes with ferrocene-additive fuel and the family of curves shown in FIG. 9 showing the corresponding courses without the addition of ferrocene under otherwise identical operating conditions. It can be seen that ferrocene brings about a clear equalization of the cycle variations and thus favorable conditions for engine running and fuel utilization.
