The method is useful for controlling corrosion.

Description

PROCEDE DE PROTECTION DES MOTEURS A COMBUSTION INTERNE ET
APPLICATION DE COMPOSE A BASE DE CERIUM A LA PROTECTION DES
MOTEURS CONTRE L'USURE ET L'OXYDATION.METHOD FOR PROTECTING INTERNAL COMBUSTION ENGINES AND
APPLICATION OF CERIUM-BASED COMPOUND TO THE PROTECTION OF
ENGINES AGAINST WEAR AND OXIDATION.

La présente invention a pour objet un procédé de protection des moteun à combustion interne. The present invention relates to a method for protecting moteun internal combustion.

EUe a plus particulièrement pour objet l'application d'un additif À base de
Cérium 9 h protection des moteurs contre rusure et roxydation.More particularly, it relates to the application of an additive based on
Cerium 9 h engine protection against rusure and roxidation.

Parmi les problèmes à résoudre pour augmenter la longévité des moteurs il convient de faire une place particulière à rarrachement progressif des matériaux constituts des pièces en mouvement du moteur. Among the problems to be solved in order to increase the longevity of the engines, it is advisable to make a special place for the gradual removal of the materials constituting the moving parts of the engine.

En particulier, cette élimination des couches superficielles des matéaaux est particulièrement aiguë pour les parties qui sont en contact avec les gaz de combustion interne avant ou après la phase de combustion. In particular, this removal of the surface layers of the materials is particularly acute for the parts that are in contact with the internal combustion gases before or after the combustion phase.

Ces gaz sont en effet très agressifs visffivis des alliages constitutifs des chambres d'explosion, ce qui conduit À utiliser des matériaux de plus en plus sophistiqués1 très couteux et ce sans que cela permette de résoudre les problèmes. These gases are indeed very visifivis visions of the constituent alloys of the explosion chambers, which leads to the use of increasingly sophisticated materials1 very expensive and this without it solves the problems.

Parmi les agressions que subit le moteur, on peut citer d'une part celle purement mécanique occasionnée par le frottement de deux pièces en mouvement de dureté similaire et celle liée aux variations de dimension en raison de la différence de température considérable entre un moteur au repos et un moteur en marche. Among the aggressions that the engine undergoes, we can cite on the one hand purely mechanical caused by the friction of two moving parts of similar hardness and that related to dimensional variations due to the considerable temperature difference between a motor at rest and a motor running.

Cest pourquoi un des buts de la présente invention est de foumir des additifs qui permettent de supprimer ou de réduire l'abrasion réciproque des pièces en mouvement
Une autre cause de dégradation des surfaces du moteur est due à l'oxydation, parfois sélective, des métaux constitutifs des alliages utilisés, dest pourquoi un autre but de la présente invention est de fournir un additif qui permette de réduire les phénomènes d'oxydation À la surface des pièces mises en contact avec les gaz de combustion d'un combustible hydrocarboné.Therefore, one of the aims of the present invention is to provide additives that eliminate or reduce the mutual abrasion of moving parts.
Another cause of degradation of the engine surfaces is due to the oxidation, sometimes selective, of the constituent metals of the alloys used, for which purpose another object of the present invention is to provide an additive which makes it possible to reduce the oxidation phenomena the surface of the parts brought into contact with the combustion gases of a hydrocarbon fuel.

Un autre but de la présente invention est de fournir un additif du type précédent qui permette d'alléger le cahier des charges pesant sur les alliages constitutifs des pièces en mouvement des moteurs. Another object of the present invention is to provide an additive of the above type which allows to lighten the specifications on the constituent alloys of the moving parts of the engines.

Ces buts, et d'autres qui apparaîtront par la suite sont atteints par l'utilisation dun additif contenant au moins un composé de Cérium pour la protection des moteurs conte rusure et oxydation lequel composé est choisi de manière qu'il soit soluble ou pseudo-soluble dans les hydrocarbures liquides et introduit dans le carburant alimentant le moteur à combustion interne à une concentration de manière À former une solution, un sol, une suspension ou une émulsion d'un composé du Cérium et ce à une concentration telle que le cérium soit présent dans le dit carburant À une concentration au moins égale à 5 de préférence à 10 P.P.M.(en masse). These and other objects which will become apparent are attained by the use of an additive containing at least one cerium compound for the protection of the engine against oxidation and oxidation which compound is chosen so that it is soluble or pseudo soluble in liquid hydrocarbons and introduced into the fuel supplying the internal combustion engine at a concentration so as to form a solution, a sol, a suspension or an emulsion of a cerium compound and at a concentration such that cerium is present in said fuel at a concentration of at least 5, preferably 10 PPM (by mass).

L'expression de "pseudo-soluble" vise les suspensions ou les émulsions qui, bien que ne constituant pas des solutions au sens strict du terme, ont une stabilité dans les hydrocarbures suffisante pour que pendant l'utilisation d'un plein dans des conditions normales, aucune modification significative de l'émulsion ou de la suspension n'ait lieu. The term "pseudo-soluble" refers to suspensions or emulsions which, although not constituting solutions in the strict sense of the term, have sufficient stability in hydrocarbons that during use of a solid under conditions normal, no significant change in the emulsion or suspension takes place.

Avantageusement, la concentration en Cérium du combustible est comprise entre 10 et 500, de préférence de 50 à 200 parties par million (en masse). Advantageously, the concentration of cerium of the fuel is between 10 and 500, preferably from 50 to 200 parts per million (by mass).

U est envisageable d'obtenir des bonnes protections à partir de solutions de sels de cérium III à condition que ces dernières soient stables dans les carburants usuels et notamment les gazoles usuels. Si l'on ne maitrise pas la forme sous laquelle ils sont peu de temps après leur introduction dans le combustible en général le gazole, il estpréférable d'ajouter le composé du cérium au deeeer moment ou de manière extemporanée. It is conceivable to obtain good protections from solutions of cerium III salts provided that they are stable in the usual fuels and in particular the usual gas oils. If one does not control the form in which they are shortly after their introduction into the fuel in general the diesel fuel, it is better to add the cerium compound at the moment or extemporaneously.

Lorsque ledit composé du cérium est choisi parmi les composés de cérium
IV, il présente en outre ravantage d'être accessible à des niveaux de forte concentration ce qui réduit la taille du réservoir, nécessaire en cas d'intrtion extemporanée Ainsi il est possible d'obtenir de concentration pouvant atteindre 15% en cérium fréquemment 20%, voire 30%.When said cerium compound is selected from cerium compounds
IV, it also has the advantage of being accessible at high concentration levels which reduces the size of the tank, necessary in case of extemporaneous intrtion Thus it is possible to obtain a concentration of up to 15% cerium frequently 20% or 30%.

Un autre avantage des composés tétravalents est une la stabilité supérieure à celle des trivalents. Another advantage of the tetravalent compounds is a higher stability than trivalents.

Les bonnes protections préférées sont celles obtenues par combustion d'un combustible, ou carburant, (contenant ou non des additifs, comme le gazole) contenant au moins un composé du cérium W (sous forme de sol ou de solution) tel que par exemple ceux décrits dans la demande de brevet européen déposée au nom de la demanderesse sous le N- 83 401 152.0. Preferred good protections are those obtained by combustion of a fuel, or fuel, (whether or not containing additives, such as gas oil) containing at least one cerium compound W (in the form of sol or of solution) such as for example those described in the European patent application filed in the name of the applicant under N-83 401 152.0.

U a été montré au cours de l'étude qui a mené à la présente invention qu'avantageusement ledit composé du cérium W est choisi parmi les sols. It has been shown in the course of the study which led to the present invention that advantageously said cerium W compound is selected from soils.

Pour obtenir une bonne protection, on préfère brûler les sols obtenus par dilution, de préférence extemporanée, dans un combustible, ou carburant, d'un sol concentré (au moins 15 à 20% d' oxyde de cérium (CeO2)) dans une fraction pétrolière telle que celle vendue sous la marque Solvesso # 150 et stabilisé par des acides gras de C15 À C25 de préférence linéaires tels que les acides oléiques, linoléiques et linoléniques ou stéarique, la taille hydrodynamique des particules formant le sol étant avantageusement comprise entre 1 et 20 millimicron. To obtain good protection, it is preferred to burn the soils obtained by dilution, preferably extemporaneously, in a fuel, or fuel, of a concentrated sol (at least 15 to 20% of cerium oxide (CeO 2)) in a fraction. oil such as that sold under the trademark Solvesso # 150 and stabilized with C15 to C25 fatty acids, preferably linear such as oleic, linoleic and linolenic or stearic acids, the hydrodynamic size of the particles forming the sol being advantageously between 1 and 20 millimicron.

La concentration en cérium dans le combustible, et notamment b gazole, est avantageusement comprise entre 10 et 200 ppm de préférence entre 50 et 150 ppm. The concentration of cerium in the fuel, and especially gas oil, is advantageously between 10 and 200 ppm, preferably between 50 and 150 ppm.

Cette technique de mise en contact du Cérium avec la surface à protéger d'un alliage est transposable À d'autres applications qu'à celle des moteurs, elle permet notamment de protéger toute surface mise en contact avec une flamme formée par un hydrocarbure liquide contenant des composés du Cérium, qui eux sont solubles ou pseudo-solubles. This technique of bringing Cerium into contact with the surface to be protected from an alloy is transferable to other applications than to that of the engines, it notably makes it possible to protect any surface brought into contact with a flame formed by a liquid hydrocarbon containing cerium compounds, which are soluble or pseudo-soluble.

Lorsqu'U n'y a pas abrasion cette protection peut être acquise une fois pour toute ou être renouvelée de temps à autre. When there is no abrasion this protection can be acquired once and for all or be renewed from time to time.

Cette protection est particulièrement sensible et efficace lorsqu'elle est appliquée à des alliages contenant un métal trivalent soit de la famille du chrome, soit de la famille de raluminium, de préférence le chrome et l'aluminium. This protection is particularly sensitive and effective when applied to trivalent metal-containing alloys of either the chromium family or the aluminum family, preferably chromium and aluminum.

Un autre but de la présente invention est de fournir un precdé de protection des motews. Another object of the present invention is to provide a precede protection of motews.

Ce but est atteint par un procédé qui comporte les étapes successives ou simultanées suivantes:
-introduction dans le combustible du moteur à combustion interne d'un
composé organo-soluble ou pseudo-organo-soluble du Cérium;
-conditionnement du moteur par mise en marche de ce dernier;
-alimentation par la suite du moteur par des carburants dont la teneur en
Cérium est au moins égales à 10 P.P.M.This goal is achieved by a method which comprises the following successive or simultaneous steps:
-Introduction into the fuel of the internal combustion engine of a
organo-soluble or pseudo-organo-soluble cerium compound;
-conditioning the engine by turning on the latter;
-feeding thereafter of the engine with fuels whose content in
Cerium is at least equal to 10 PPM

Pour obtenir de bons résultats et que l'effet soit détectable, b durée du préconditionnement du moteur doit être telle que la quantité de Céuum réputée avoir transité dans le moteur soit au moins égale à 1 avantageusement À 10 grammes de préférence À 20 g par litre de cylindrée. To obtain good results and the effect to be detectable, the duration of the preconditioning of the engine must be such that the quantity of Ceeprum deemed to have passed through the engine is at least equal to 1 advantageously to 10 grams, preferably to 20 g per liter. of displacement.

Ainsi selon la présente invention on peut moduler la durée dudit condiüonnement en jouant sur la concentration du cérium dans le carburant du moteur à combustion interne. Toutefois il est souhaitable que la concentration en cérium n'excbde pas 10 gramme par litre de préférence 1g par litre de carburart
Si Fon désire conditionner le moteur en utilisant le carburant usuel il faut atteinre au moins une cinquantaine d'heures. de préférence une certaine d'heure mais le préconditionnemment ne constitue en fait qu'une marche nom pendant laquelle la protection du moteur par le cérium n'est que peu ou pas assurée. Thus, according to the present invention, it is possible to modulate the duration of said conditioning by varying the concentration of cerium in the fuel of the internal combustion engine. However, it is desirable that the concentration of cerium not exceed 10 gram per liter, preferably 1 gram per liter of carburate.
If you wish to condition the engine using the usual fuel, you must reach at least 50 hours. preferably a certain time, but preconditioning is in fact only one name during which the protection of the engine with cerium is only little or not assured.

L' exemple non limitatif suivant illustre l'invention. The following nonlimiting example illustrates the invention.

EXEMPLE
