Abstract

The method involves incorporating or injecting stoichiometric mixture of gas that is obtained during electrolytic decomposition of water, in carburization air. An electrolytic cell of an electrolysis device is operated when a heat engine is running. A gas production cell of the electrolysis device is servo-controlled by electric impulsions generated by an electronic module, where the electrolytic cell of the electrolysis device is supplied with high purity water. Independent claims are also included for the following: (1) a method for improving carburization of a heat engine (2) a method for utilization of a carburization improving device.

Description

La carburation des moteurs thermiques est assurée par de l'air en provenance de l'atmosphère dont la composition est pratiquement constante. L'injection dans cet air des gaz en provenance de la décomposition électrolytique de l'eau, permet de constater contre toute attente des différences de fonctionnement desdits moteurs allant dans le sens positif. Dès la mise en route de la cellule électrolytique, suite au démarrage du moteur et à l'injection des gaz dans l'air d'aspiration de celui-ci, voire du turbo, on constate : 1. une modification immédiate du niveau sonore du moteur; 2. que la température du moteur se stabilise aux alentours de 75 degrés, élément prépondérant dans le résultat de l'application de l'adjuvant gazeux ; si l'on coupe l'arrivée des gaz de dissociation de l'eau, on retourne à la température habituelle de fonctionnement du moteur. Sur route, on constate que le nombre de kilomètres parcourus avec l'injection des gaz de dissociation de l'eau augmente, et le moteur accuse une consommation pouvant être inférieure de l'ordre de 30 % en fonction du type de moteur utilisé, de sa cylindrée et de son état de vétusté. Le dosage du CO2 dans les gaz d'échappement montre une diminution, qui est la conséquence de ces variations de consommation. On constate une diminution des NOx d'environ 60%, ceci étant dû à la température de 20 fonctionnement du moteur, indépendante de la variation de CO2, ceci étant lié à la consommation du moteur. On constate la diminution de l'opacité des fumées à plus de 60%. On constate moins de particules noires dans les huiles de lubrification et on note, dans les moteurs anciens, un décalaminage progressif des chambres de combustion.The carburetion of the thermal engines is ensured by air coming from the atmosphere whose composition is practically constant. The injection into this air of the gases from the electrolytic decomposition of the water makes it possible to observe, against all odds, differences in operation of said engines going in the positive direction. As soon as the electrolytic cell is switched on, after starting the engine and injecting the gases into the suction air of the latter, or even the turbo, there is: 1. an immediate change in the noise level of the engine; 2. that the engine temperature stabilizes at around 75 degrees, a predominant element in the result of the application of the gaseous adjuvant; if we cut off the water dissociation gas, we return to the normal operating temperature of the engine. On the road, it can be seen that the number of kilometers traveled with the injection of the water dissociation gases increases, and the engine shows a consumption that can be lower by around 30% depending on the type of engine used, its engine capacity and its state of obsolescence. The measurement of CO2 in the exhaust gas shows a decrease, which is the consequence of these consumption variations. There is a decrease in NOx of about 60%, this being due to the operating temperature of the engine, independent of the variation of CO2, this being related to the consumption of the engine. The smoke opacity decreases to more than 60%. There are fewer black particles in the lubricating oils and in older engines there is a gradual descaling of the combustion chambers.

25 L'utilisation de l'hydrogène comme carburant principal par apport sous forme de gaz comprimé, n'est pas nouveau : des exemples sont cités dans la littérature depuis 1912. L'hydrogène n'est pas cité comme carburant secondaire. En aucun cas l'utilisation d'un mélange des gaz de décomposition électrolytique de l'eau, non séparés, dans un rapport stoechiométrique, n'est cité ni comme adjuvant de carburation, ni comme carburant.The use of hydrogen as a main fuel in the form of a compressed gas is not new: examples have been cited in the literature since 1912. Hydrogen is not mentioned as a secondary fuel. In no case is the use of a mixture of electrolytic decomposition gases of water, not separated, in a stoichiometric ratio, is cited neither as a carburization adjuvant nor as a fuel.

30 La dilution dans l'air de carburation du mélange gazeux représente un apport de l'ordre de 0.2% dans les prototypes que nous utilisons, sans pour autant que ce pourcentage ne soit limitatif. Bien que ce pourcentage de dilution dans l'air primaire soit relativement faible, on montre l'importance très significative de l'effet de ce mélange stoechiométrique.The dilution in the carburizing air of the gaseous mixture represents a contribution of the order of 0.2% in the prototypes that we use, without this percentage being limiting. Although this percentage of dilution in the primary air is relatively low, the very significant importance of the effect of this stoichiometric mixture is shown.

35 Les cellules de production du mélange gazeux sont asservies au fonctionnement du moteur par l'intermédiaire d'un générateur d'impulsions électriques, lui-même piloté électroniquement en fonction de la puissance demandée par le moteur. L'appareil nécessaire à la production du mélange gazeux est un dispositif particulier, ne comprenant pas de membrane de séparation entre les gaz produits, ni même aucun 40 système de séparation de ceux-ci. Les électrodes utilisées sont constituées de métaux inoxydables traités spécialement pour éviter les phénomènes parasites. L'eau destinée à l'électrolyseur doit être d'une grande pureté et en aucun cas ne contenir des ions Chlore. La conductibilité de cette eau est gérée par l'apport d'un sel organique associé à une base choisie dans la série des métaux alcalins. Bien qu'il soit difficile de définir à ce jour d'une façon précise l'action de ce mélange gazeux, force est de constater la réalité de ses effets positifs sur le fonctionnement du moteur thermique. L'une des explications possibles est l'action du mélange dissocié sur le développement de la flamme à l'intérieur du cylindre de combustion. D'autre part, l'apport du gaz de dissociation de l'eau étant dans un rapport stoechiométrique, la totalité de l'énergie de liaison est reconstituée lors de l'explosion du mélange à l'intérieur de la chambre de combustion.10 The cells for producing the gaseous mixture are slaved to the operation of the engine by means of an electric pulse generator, itself electronically controlled according to the power demanded by the engine. The apparatus necessary for the production of the gaseous mixture is a particular device, comprising no separation membrane between the gases produced, nor even any system for separating them. The electrodes used consist of stainless metals specially treated to avoid parasitic phenomena. The water intended for the electrolyser must be of high purity and in no case contain chlorine ions. The conductivity of this water is managed by the addition of an organic salt associated with a base selected from the series of alkali metals. Although it is difficult to define so far the action of this gas mixture, the reality of its positive effects on the operation of the heat engine is noticeable. One of the possible explanations is the action of the dissociated mixture on the development of the flame inside the combustion cylinder. On the other hand, the supply of the dissociation gas of the water being in a stoichiometric ratio, the totality of the binding energy is reconstituted during the explosion of the mixture inside the combustion chamber.
