Definitions

  • piston engines both ignition and diesel
  • combustion Under the broad term of combustion there are actually many chemical reactions that occur and overlap, discharging energy in a way that is apparently chaotic but in fact conditioned by temperature, pressure, the state of the matter, type of fuel, quantity of comburent and, last but not least, the possible presence of positive and negative catalysts.
  • Combustion is not always perfect, however, and engines tend to detonate and to discharge unburnt gases. Many improvements have been achieved in recent years in engine studies as well as in chemistry, additives, fuels and afterburning catalysis in order to solve these shortcomings.
  • metallorganic compounds lead, manganese, etc.
  • these compounds reduce the combustion speed in the combustion chamber.
  • the present state of technical knowledge includes a catalysed chemical process for use in reciprocating internal combustion engines to improve fuel quality, filed as an Italian Patent Application by the applicant for the present Patent on July 4th 1994 with Report No. TS94A000007.
  • the aforementioned Patent application describes a catalysed chemical process consisting in a particular fixed-bed hydrogenating catalytic cracking process by means of solid-gas surface catalysis taking place within the combustion chamber during the normal running of the engine.
  • This process transforms high-boiiing hydrocarbons into low-boiling hydrocarbons with a consequent increase in the octane number.
  • the pressure increase caused by the combustion itself is exploited to split the hydrocarbon molecules. Without the catalysts described in the Patent Application the combustion would cause a detonation.
  • This cracking process uses as a support for the catalysts the carbon deposits usually found in the combustion chamber and on the inner walls of exhaust pipes.
  • the catalysts used consist of spinel structured double or mixed metal oxides derived from the thermic decomposition of metallorganic compounds added to fuel. These oxides perform the dual function of promoting low- temperature hydrogenating catalytic cracking and acting as combustion catalysts at high temperature. Both these conditions occur in the combustion chamber at every explosion - low temperature at the beginning of mixture ignition, high temperature as combustion progresses. A part of the oxides, leaving the cylinder together with the exhaust gases, permeates the deposits covering the inner walls of the exhaust pipes, transforming the deposits into a catalytic discharge which further reduces the quantity of unburnt gases.
  • the precursors of "process catalysts” are metallorganic compounds which on thermic decomposition form spinel-structured double and mixed oxides of iron, cobalt and nickel. Disclosure of Invention
  • the purpose of the present invention is to make available to consumers a further series of catalyzers able to exploit the chemical process described in the aforementioned Patent Application No. TS94A000007.
  • Another purpose is to improve fuel at the moment of combustion, reducing detonation and catalyzing the complete combustion to CO2 and H2O.
  • additives are made up of metal salts in solution or metallorganic compounds that, with the high pressures and temperatures developed in the combustion chamber while the engine is running, through pyrolysis form ionic solids with the hexahoctahedric spinel structure, inverted spinel or disordered spinel structures formed by the double or mixed oxides of the various metals.
  • metals are introduced into the combustion chamber in the form of fuel-soluble metallorganic compounds or salts of the various metals in aqueous solution, in the latter case introduced together with the induction air by means of a nebulizer.
  • Metallorganic compounds are preferable, however.
  • Each group of metals in the list has its own catalytic properties, but it is possible to mix groups together to obtain compromises between the various reactions.
  • the quantities of metals contained in the fuel additives vary from 0.5 to 10 grammes per 1 ,000 litres of fuel.
  • the attributes of the catalyzers used are:
  • the catalyzers in question have the characteristic of not being poisoned by the presence of water vapour, nitrogen, sulphur, calcium, sodium, potassium, etc. Indeed, these substances seem to facilitate the reactions of the process.
  • the catalyzers are also able to promote the cracking of the hydrocarbons inside the combustion chamber, catalyze the hydrogenation of the olefines (alkenes) produced by the cracking at the expense of the humidity of the comburent air, which is used as H-OH ions, and facilitate the complete combustion of fuel and comburent to CO2 and H2O.
  • TS94A000007 exploits the coked carbon deposits covering the inside of the combustion chamber (piston head and crown) and the inside of the exhaust pipes. These deposits have a micropore structure with a high specific surface, which makes them an ideal support for "process catalysts".
  • the metal oxides derived from the additives in question are thrown and pressed on to the deposits, penetrate the pores and, since the deposits are almost incandescent, some oxides form a chemical bond with the carbon in the deposits, settling there permanently. The result is a catalytic bed able to promote heterogenous-phase solid/gas reactions.
  • the engine is more responsive and flexible if the temperature in the cooling system is 10-15 degrees lower than the running temperature;
  • the stoichiometric fuel-air ratio is modified, the mixture is richer, especially when the engine is cold (only for engines with carburettors); 9) in petrol engines the average running temperature is lower, which allows the fitting of hotter sparking plugs;

Abstract

Additifs trouvant application dans le domaine des carburants et des moteurs à explosion à piston. Ces additifs sont constitués de composés organométalliques ou de solutions de sels métalliques, lesquels se transforment, par décomposition thermique au cours du fonctionnement normal du moteur, en solides ioniques ayant la structure hexaoctaédrique du spinelle, celle du spinelle inversé ou les structures désordonnées du spinelle ou du grenat. Lesdits additifs facilitent un type particulier de craquage catalytique à hydrogénation par catalyse de surface solide-gaz à l'intérieur de la chambre de combustion au cours du fonctionnement normal du moteur. Ces solides ioniques ont la fonction double de favoriser le craquage catalytique à hydrogénation aux basses températures, et de faire office de catalyseurs de combustion aux températures élevées, ces deux conditions prévalant dans la chambre de combustion à chaque explosion.
