  "Procédé et dispositif pour éviter la pollution de l'atmosphère par des gaz nocifs tels que les oxydes d'azote et le monoxyde

  
de carbone" L'invention concerne essentiellement des perfectionnements au procédé et au dispositif décrits dans le brevet principal, et concerne notamment les corps chimiques susceptibles d'être utilisas en combinaison avec la vapeur d'eau pour détruire les composés polluants des gaz rejetés à l'atmosphère, tels que les hydrocarbu-

  
 <EMI ID=1.1> 

  
l'anhydride sulfureux.

  
Dans le brevet principal, on a décrit un procédé qui permet d'éviter la pollution de lf,atmosphère par de tels gaz nocifs, ce procédé consistant à empêcher la formation et/ou à provoquer la

  
 <EMI ID=2.1> 

  
de formation des gaz nocifs et que l'on fait passer sur du cérium ou sur un composé contenant du cérium.

  
Selon les perfectionnements de la présente invention, le procédé pour éviter la pollution de l'atmosphère par des gaz nocifs, et notamment par ceux contenus dans les gaz d'échappement d'un moteur à combustion interne, consistant à empêcher la formation et/ou à provoquer la décomposition, au moyen de vapeur d'eau, de ces gaz nocifs, est caractérisé en ce qu'on fait passer la vapeur d'eau sur un élément contenant du cérium ou du germanium, et qu'on élimine totalement, dans les gaz d'échappement, les gaz nocifs tels que les oxydes d'azote, les hydrocarbures imbrûlés l'anhydride sulfureux, et le monoxyde de carbone.

  
Selon une autre caractéristique de la présente invention, l'élément précité est un alliage ou un composé de cérium ou de germanium avec un métal tel que par exemple le fer.

  
Selon encore une autre caractéristique de l'invention, cet

  
 <EMI ID=3.1> 

  
36 à 40% de cérium, ou bien de 45 à 80% de germanium.

  
C'est en effet avec ces pourcentages de cérium et de germanium que les meilleurs résultats sont obtenus, les pourcentages des gaz nocifs précités (hydrocarbures imbrûlés. , monoxyde ' de carbone, . oxydes d' azote et anhydride sulfureux) dans les gaz d'échappement d'un moteur à combustion interne étant alors sensiblement nuls.

  
. 

  
L'invention sera mieux comprise et d'autres buts, détails, caractéristiques et avantages de celle-ci apparaîtront mieux au cours de la description explicative qui va suivre, en se reportant aux dessins schématiques annexés donnés uniquement à titre d'exemple, et dans lesquels :
- la figure 1 est un graphe illustrant l'influence du procédé selon l'invention sur la puissance d'un moteur à combustion interne ;
- la figure 2 est un graphe illustrant l'influence du procédé selon l'invention sur la consommation spécifique d'un moteur à combustion interne ; et
- la figure 3 est un graphe illustrant l'influence du procédé selon l'invention sur les pourcentages de composés nocifs contenus dans les gaz d'échappement d'un moteur à combustion interne.

  
Comme cela est décrit au brevet principal, le procédé selon l'invention consiste à amener, dans le système d'admission d'un moteur à combustion interne, par exemple de véhicule automobile , de la vapeur d'eau que l'on fait ensuite passer sur un élément, tel qu'un composé ou un alliage, contenant du cérium ou du germanium.

  
La vapeur d'eau peut être amenée, comme décrit au brevet principal, directement dans le Venturi d'un carburateur du moteur à combustion interne, l'élément contenant du cérium ou du germanium, par exemple une grille, étant alors placé en aval du Venturi du carburateur.

  
Ou bien, selon les perfectionnements de la présente invention, l'amenée de vapeur d'eau peut se: faire directement dans le filtre à air du moteur à combustion interne, et dans ce cas l'élément contenant le cérium ou le germanium peut être placé dans la canalisation d'amenée de vapeur d'eau dans le fil à air. Avantageusement, les dimensions de cette canalisation, et notamment sa section, sont déterminées en fonction du moteur à combustion interne considéré, c'est-à-dire du nombre de cylindres, de la puissance développée, etc. Cette canalisation peut également être pourvue d'une vanne de réglage de sa section, permettant ainsi d'effectuer un réglage fin du débit de vapeur d'eau amenée au moteur.

  
L'élément contenant le cérium ou le germanium peut être, comme on l'a dit plus haut, un alliage ou un composé de cérium ou de germanium avec un métal. tel que le fer. Cet élément peut se présenter sous la forme d'un fil torsadé, que l'on dispose dans la canalisation d'amenée de vapeur d'eau, en permettant ainsi son remplacement . aisé - au bout d'un certain temps. Le cérium ou le germanium disparaissant durant le fonctionnement du moteur, on peut

On peut également doubler la première canalisation citée  d'amenée de vapeur d'eau par une autre canalisation en parallèle,  ayant une section inférieure, et destinée à l'amenée de vapeur 

  
d'eau dans le filtre à air ou dans le système d'admission du moteur, 

  
 <EMI ID=5.1> 

  
seconde canalisation comprendra également un élément contenant du  cérium ou du germanium, par exemple un fil torsadé. 

  
On a également constaté que les meilleurs résultats, du point  de vue de l'épuration des gaz d'échappement d'un moteur à combus-  tion interne, étaient obtenus lorsque le pourcentage de cérium dans 

  
 <EMI ID=6.1> 

  
préférence entre 36 et 40%. Pour le germanium, ces pourcentages 

  
sont compris entre 45 et 80%. 

  
Dans les figures 1, 2 et 3, on a représenté les résultats ob-  tenus avec un moteur à combustion interne équipé du dispositif se-  lon l'invention, du point de vue de la puissance délivrée, de la  consommation spécifique, et des pourcentages de composés polluants.  Dans ces trois figures, les courbes obtenues pour un moteur équipé du dispositif selon l'invention sont représentés en traits pleins, tandis que les courbes obtenues pour un moteur selon l'art antérieur non équipé du dispositif selon l'invention, sont représentées en traits pointillés.

  
La figure 1 représente la variation de puissance en chavaux vapeur délivrée par le moteur, en fonction du régime de fonction- <EMI ID=7.1>  La figure 2 représente les variations de consommation spécifique ( en grammes) de ce moteur, en fonction de son régime de fonctionnement, en tours par minutes.

  
Enfin, la figure 3 représente le pourcentage de monoxyde

  
de carbone présent dans les gaz d'échappement du moteur, en fonction de son régime de fonctionnement, en tours par minutes. Ce

  
 <EMI ID=8.1> 

  
d'échappement par chromatographie en phase gazeuse. On constate que, dans un moteur à combustion interne non équipé du dispositif selon l'invention, le pourcentage de monoxyde de carbone varie entre 4 et 5,5% en fonction du régime du moteur, tandis que ce pourcentage est complètement nul pour un moteur équipé du dispositif selon l'invention. De même, on a constaté que les pourcentages

  
 <EMI ID=9.1> 

  
fureux, qui sont généralement compris entre 1 et 3%, sont sensiblement nuls dans le cas d'un moteur à combustion interne équpé du dispositif selon l'invention.

  
On voit donc, sur ces trois figures, que l'application de

point de vue de la puissance, de la consommation spécifique que de

  
la propreté des gaz d'échappement rejetés à l'atmosphère.

  
On a également constaté, dans le cas d'un moteur à combustion  interne, que les meilleurs résultais sont obtenus lorsque le  pointeau de ralenti du carburateur est réglé pourra formation d'un  mélange combustible pauvre, le réglage du gicleur de puissance res-  tant normal ou inchangé.

La présente invention se traduit donc, non par un appauvrissement du mélange. combustible , mais par son enrichissement ce qui provoque une meilleure carburation et une meilleur combustion, non seulement au régime normal du moteur, mais également au ralenti.

  
Enfin, il est important de noter que l'invention s'applique à des moteurs à combustion interne, à carburateur ou à injectinn directe ou du type Disuel, à des moteurs à turbines, à des turboréacteurs, à des chauffages domestiques, à des cheminées industrielles, en procurant les mêmes résultats avantageux du point de vue de la lutte contre la pollution par les gaz ou fumées

  
 <EMI ID=12.1> 

  
Il est donc bien entendu, que l'invention n'est nullement limitée aux modes de réalisation décrits qui dont été donnés qu'à titre d'exemple. En particulier, l'invention comprend tous les équivalents techniques des moyens décrits, ainsi que leurs combinaisons, si celles-ci sont réalisées suivant son esprit et mises en oeuvre dans le cadre des revendications qui suivent.

In the main patent, a method has been described which makes it possible to avoid the pollution of the atmosphere by such harmful gases, this method comprising preventing the formation and / or causing the formation.

  
 <EMI ID = 2.1>

  
formation of noxious gases and passed over cerium or a compound containing cerium.

  
According to the improvements of the present invention, the method for avoiding pollution of the atmosphere by harmful gases, and in particular by those contained in the exhaust gases of an internal combustion engine, consisting in preventing the formation and / or to cause the decomposition, by means of water vapor, of these noxious gases, is characterized in that the water vapor is passed over an element containing cerium or germanium, and that it is completely eliminated, in exhaust gases, noxious gases such as nitrogen oxides, unburnt hydrocarbons sulfur dioxide, and carbon monoxide.

  
According to another characteristic of the present invention, the aforementioned element is an alloy or a compound of cerium or germanium with a metal such as for example iron.

  
According to yet another characteristic of the invention, this

  
 <EMI ID = 3.1>

  
36 to 40% cerium, or 45 to 80% germanium.

  
It is in fact with these percentages of cerium and germanium that the best results are obtained, the percentages of the aforementioned noxious gases (unburnt hydrocarbons, carbon monoxide, nitrogen oxides and sulfur dioxide) in the gases. exhaust from an internal combustion engine then being substantially zero.

  
.

  
The invention will be better understood and other objects, details, characteristics and advantages thereof will become more apparent in the course of the explanatory description which follows, with reference to the appended schematic drawings given solely by way of example, and in which :
- Figure 1 is a graph illustrating the influence of the method according to the invention on the power of an internal combustion engine;
FIG. 2 is a graph illustrating the influence of the method according to the invention on the specific consumption of an internal combustion engine; and
- Figure 3 is a graph illustrating the influence of the process according to the invention on the percentages of harmful compounds contained in the exhaust gases of an internal combustion engine.

  
As described in the main patent, the method according to the invention consists in bringing, into the intake system of an internal combustion engine, for example of a motor vehicle, water vapor which is then made pass over an element, such as a compound or an alloy, containing cerium or germanium.

  
The water vapor can be brought, as described in the main patent, directly into the Venturi of a carburetor of the internal combustion engine, the element containing cerium or germanium, for example a grid, then being placed downstream of the Carburetor venturi.

  
Or, according to the improvements of the present invention, the supply of water vapor can be: done directly in the air filter of the internal combustion engine, and in this case the element containing cerium or germanium can be placed in the water vapor supply pipe in the air wire. Advantageously, the dimensions of this pipe, and in particular its section, are determined as a function of the internal combustion engine considered, that is to say the number of cylinders, the power developed, etc. This pipe can also be provided with a valve for adjusting its section, thus making it possible to fine-tune the flow of water vapor supplied to the engine.

  
The element containing cerium or germanium can be, as mentioned above, an alloy or a compound of cerium or germanium with a metal. such as iron. This element can be in the form of a twisted wire, which is placed in the water vapor supply pipe, thus allowing its replacement. easy - after a while. As cerium or germanium disappears during engine operation, it is possible to

  
 <EMI ID = 4.1>

  
nium so that it has a duration corresponding to a certain number of hours of operation of the engine, or else to a certain number of thousands of kilometers traveled by the vehicle equipped with this internal combustion engine.

  
It is also possible to double the first mentioned pipe for supplying water vapor by another pipe in parallel, having a lower section, and intended for supplying steam.

  
water in the air filter or in the engine intake system,

  
 <EMI ID = 5.1>

  
second pipe will also include an element containing cerium or germanium, for example a twisted wire.

  
It has also been found that the best results, from the point of view of cleaning the exhaust gases of an internal combustion engine, are obtained when the percentage of cerium in

  
 <EMI ID = 6.1>

  
preferably between 36 and 40%. For germanium, these percentages

  
are between 45 and 80%.

  
In FIGS. 1, 2 and 3, the results obtained with an internal combustion engine equipped with the device according to the invention have been shown, from the point of view of the power delivered, of the specific consumption, and of the percentages. polluting compounds. In these three figures, the curves obtained for an engine equipped with the device according to the invention are shown in solid lines, while the curves obtained for an engine according to the prior art not equipped with the device according to the invention are shown in lines. dotted lines.

  
Figure 1 shows the variation in steam power delivered by the engine, depending on the operating speed - <EMI ID = 7.1> Figure 2 shows the variations in specific consumption (in grams) of this engine, depending on its operating speed, in revolutions per minute.

  
Finally, figure 3 represents the percentage of monoxide

  
of carbon present in the exhaust gases of the engine, according to its operating speed, in revolutions per minute. This

exhaust by gas chromatography. It can be seen that, in an internal combustion engine not equipped with the device according to the invention, the percentage of carbon monoxide varies between 4 and 5.5% depending on the engine speed, while this percentage is completely zero for an engine. equipped with the device according to the invention. Likewise, it has been observed that the percentages

  
 <EMI ID = 9.1>

  
furious, which are generally between 1 and 3%, are substantially zero in the case of an internal combustion engine equipped with the device according to the invention.

  
We can therefore see, in these three figures, that the application of

  
 <EMI ID = 10.1>

  
significant improvement in engine performance, both

  
power point of view, specific consumption as well as

  
the cleanliness of the exhaust gases discharged into the atmosphere.

  
It has also been observed, in the case of an internal combustion engine, that the best results are obtained when the idle speed needle of the carburettor is adjusted may form a lean fuel mixture, the setting of the power nozzle remaining normal. or unchanged. Despite the lean, idle setting, the engine runs perfectly at idle, thanks to. the admission of va-
