Abstract

Running water installation for internal combustion engines in accordance with claim 1, in which the operation of water intake into the air-fuel mixture is determined by the depression generated by the engine itself during the intake phases.

Description

Dispositif d'admission d'eau pour moteurs à combustion interne. Water intake device for internal combustion engines.
Cette invention prévoit l'installation d'un réservoir auxiliaire d'eau courante alimentant électriquement un distributeur d'eau courante placé à côté du moteur. Du distributeur l'eau passe par un micro-pulvérisateur et/ou par un jet diffuseur; elle est donc aspirée dans les chambres d'explosion du moteur en améliorant la combustion.This invention provides for the installation of an auxiliary running water tank electrically supplying a running water distributor placed next to the engine. From the distributor, the water passes through a micro-sprayer and / or through a diffusing jet; it is therefore sucked into the engine's explosion chambers by improving combustion.
Précédemment l'eau qui arrivait dans les chambres d'explosion des moteurs était envoyée par injection sous pression et pour de très brefs moments.Previously the water which arrived in the explosion chambers of the engines was sent by injection under pressure and for very brief moments.
Le mélange air-carburant ne s'enflamme pas entièrement dans les chambres d'explosion, d'où une plus grande consommation de carburant et une plus grande émission d'hydrocarbures non brûlés. Cette invention a pour but d'améliorer la combustion du mélange air-carburant en l'enrichissant avec de l'eau micro-pulverisée.The air-fuel mixture does not fully ignite in the explosion chambers, resulting in greater fuel consumption and greater emission of unburned hydrocarbons. The object of this invention is to improve the combustion of the air-fuel mixture by enriching it with micro-sprayed water.
Cette invention prévoit un réservoir auxiliaire d'eau courante muni d'un flotteur qui signale, à l'aide d'un voyant le niveau minimal d'eau. Le réservoir comprend en outre un moteur électrique mis en marche à chaque fois qu' il reçoit l'impulsion du flotteur placé dans le distributeur qui se trouve du côté du moteur. Quand il y a une baisse de niveau dans le distributeur d'eau, le flotteur du distributeur donne une impulsion au moteur électrique du réservoir auxiliaire qui envoie de l'eau et rétablit le niveau; pendant cette phase de remplissage un voyant relié au flotteur signale que le distributeur d'eau est en train de se remplir. En plus d'une arrivée d'eau, le distributeur comprend une ou deux soupapes de sortie réglablés qui portent l'eau à une petite embase ayant la même forme que le soubassement du carburateur et qui se trouve sous ce dernier.This invention provides an auxiliary running water tank provided with a float which indicates, by means of an indicator light the minimum water level. The reservoir further comprises an electric motor which is started each time it receives the pulse from the float placed in the distributor which is located on the side of the motor. When there is a drop in level in the water distributor, the distributor float gives a boost to the electric motor of the auxiliary tank which sends water and restores the level; during this filling phase, an indicator light connected to the float signals that the water dispenser is filling. In addition to a water supply, the distributor includes one or two adjustable outlet valves which carry the water to a small base having the same shape as the base of the carburetor and which is under the latter.
La petite embase a une rainure interne qui s'allonge sur un quart de sa longueur totale. Elle a un bec d'accrochement sur le bord extérieur pour le tuyau qui porte l'eau dans le distributeur, à travers la soupape et un trou de sortie sur le bord intérieur. Sur cette petite embase est montée une hélice tripale, ayant un pivot d'acier comme axe. L'hélice tour ne librement dans des logements, creusés dans les deux embouts, un supérieur fixé à la petite embase et l'autre intérieur extractible d'arrêt.The small base has an internal groove which extends over a quarter of its total length. It has a hooking spout on the outside edge for the hose that carries water into the dispenser, through the valve and an outlet hole on the inside edge. On this small base is mounted a three-bladed propeller, having a steel pivot as an axis. The propeller turns freely in housings, dug in the two end pieces, an upper fixed to the small base and the other extractable interior stop.
L'ensemble, petite embase et hélice constituent le groupe micro-pulvérisateur. Le mouvement rotatif et tourbillonnaire de l'hélice est causé par la dépression que le moteur provoque pendant la phase d'aspiration. L'eau, dont la sortie est réglée par la soupape du distributeur, est aspirée, bien entendu pendant la phase d'aspiration du moteur, dans le groupe micro-pulvérisateur, où, par effet du mouvement tourbillonnaire de l'hélice, elle est homogénéisée avec les parties d'air et de carburant. Ainsi les parties d'eau, d'air et de carburant entrent-ils en étroit contact entre elles et passent dans les chambres d'explosion. Après la compression, pendant la phase d'explosion, ce nouveau mélange s'enflammera presque entièrement tout en an portant un meilleur rendement calorifique et en modifiant la composition des gaz d'échappement qui seront expulsés. Quand la soupape à papillon du carburateur est au maximum de sa course et se trouve en position verticale, l'eau ne est plus aspirée en quantités suffi santes , par le trou de la rainure placée sur la petite embase du groupe micro-pulvérisateur. Il est alors nécessaire de mettre en marche le jet diffuseur en le positionnant en amont du carburateur sur la bouche d'aspiration d'air, là où il y a une plus grande dépression.The assembly, small base and propeller constitute the micro-sprayer group. The rotary and vortex movement of the propeller is caused by the vacuum that the motor causes during the aspiration phase. The water, the outlet of which is regulated by the valve of the distributor, is sucked, of course during the suction phase of the engine, into the micro-sprayer group, where, by the effect of the vortex movement of the propeller, it is homogenized with the air and fuel parts. Thus the parts of water, air and fuel come into close contact with each other and pass into the explosion chambers. After compression, during the explosion phase, this new mixture will ignite almost entirely during the year carrying a better calorific output and by modifying the composition of the exhaust gases which will be expelled. When the butterfly valve of the carburetor is at its maximum stroke and is in the vertical position, the water is no longer sucked in sufficient quantities, through the hole in the groove placed on the small base of the micro-sprayer group. It is then necessary to start the diffuser jet by positioning it upstream of the carburetor on the air intake mouth, where there is a greater vacuum.
Le jet diffuseur se compose de trois éléments orientables selon le cas; la partie terminale du jet diffuseur est munie d'une attache pour le petit tuyau provenant de l'autre soupape placée dans le diffuseur et elle est creuse à l'intérieur pour permettre le passage de l'eau. La partie centrale du jet diffuseur comprend à l'intérieur un double cône Venturi, à travers lequel passe l'eau. La fonction du double cône Venturi est de créer un tourbillon et donc une pulvérisation. Le jet diffuseur pour certains types de moteurs, peut être en lui-même suffisant à enrichir d'eau le mélange air-carburant aspiré.The diffuser jet is made up of three orientable elements as appropriate; the terminal part of the diffuser jet is provided with a clip for the small pipe coming from the other valve placed in the diffuser and it is hollow inside to allow the passage of water. The central part of the diffuser jet includes a double Venturi cone inside, through which the water passes. The function of the Venturi double cone is to create a vortex and therefore a spray. The diffuser jet for certain types of engines, may in itself be sufficient to enrich the air-fuel mixture aspirated with water.
L'usage des systèmes eau-moteur soit du groupe micro-pulvérisateur, soit du jet diffuseur permet d'obtenir les avantages suivants: une sortie mineure des gaz d'échappement nocifs due à une diminuition remarquable d'oxyde de carbon et à une augmentation d'oxygène, enfin un meilleur rendement calorifique des moteurs. L'action et la présence de l'eau, sous forme de vapeur dans le processus de combustion, modifient la combustion elle-même en produisant un nombre remarquable de kilocalories. Ces dernières sont entièrement transformées en énergie mécanique, nécessitant à égalité de puissance une moindre quantité de carburant. Le processus de combustion avec le mélange eau-air-carburant laisse une mineure quantité d'hydrocarbures non- brûlés apportant des avantages au moteur, au niveau des chambres d'explosion et des soupapes, comme aux injecteurs et aux bougies, au niveau des gicleurs et des électrodes ainsi qu'au lubrifiant du moteur qui a moins de résidus de combustion à englober et à disperser, et à l'appareil d'expulsion des gaz d'échappement.The use of engine-water systems either from the micro-sprayer group or from the diffuser jet allows the following advantages to be obtained: a minor output of harmful exhaust gases due to a remarkable reduction in carbon monoxide and an increase oxygen, finally a better calorific efficiency of the engines. The action and presence of water, in the form of vapor in the combustion process, modify the combustion itself by producing a remarkable number of kilocalories. These are entirely transformed into mechanical energy, requiring less power for equal power. The combustion process with the water-air-fuel mixture leaves a minor amount of unburned hydrocarbons bringing benefits to the engine, at the level of the explosion chambers and the valves, as at the injectors and the spark plugs, at the level of the nozzles. and electrodes as well as the engine lubricant which has less combustion residues to encompass and disperse, and the exhaust gas expeller.
Cet appareil, par effet outre que de la mineure quantité d'hydrocarbures de passage non brûlés, que de la vapeur d'eau passant à une certaine tmpérature, s'incruste moins avec, par conséquent une mineure usure.This device, by effect besides that of the minor quantity of hydrocarbons of passage not burnt, that of the steam passing at a certain temperature, becomes less encrusted with, consequently a minor wear.
Cette invention trouve une heureuse application dans l'industrie comme installation auxiliaire à tout type de moteur à combustion interne. Elle restreint la pollution et les dépenses de carburant et permet d'allonger une plus longue durée des pièces mécaniques et d'allumage, à injection et d'explosion. This invention finds a happy application in industry as an auxiliary installation to any type of internal combustion engine. It restricts pollution and fuel costs and allows longer mechanical and ignition, injection and explosion parts to be extended.

Claims

Revendications claims
1. Installation à eau courante pour moteurs à combustion interne (endothermiques) apte à distribuer l'eau provenant d'un réservoir auxiliaire envoyée par un moteur à travers un petit tuyau qui, pour cette opération, reçoit l'impulsion d'un flotteur placé dans un diffuseur à coté du moteur.1. Running water installation for internal combustion engines (endothermic) capable of distributing the water coming from an auxiliary tank sent by an engine through a small pipe which, for this operation, receives the impulse from a float placed in a diffuser next to the engine.
A travers la soupape réglable (fig. 1) l'eau est aspirée par la dépression provoquée par le piston pendant la phase d'aspi ration. Elle entre dans le groupe micro-pulvérisateur (fig.2) à travers le petit tuyau. Par effet de la dépression provoquée par l'aspiration du moteur, l'hélice (fig. 2 n. 2) en tourbillonant, homogénéise l'eau, l'air et le carburant qui sont ainsi aspirés dans les chambres d'explosion.Through the adjustable valve (fig. 1) the water is sucked in by the vacuum caused by the piston during the suction phase. It enters the micro-sprayer group (fig. 2) through the small pipe. By effect of the depression caused by the aspiration of the engine, the propeller (fig. 2 n. 2) by whirling, homogenizes the water, the air and the fuel which are thus sucked in the explosion chambers.
Quand ia soupape à papillon est complètement ouverte en positionverticale, part le jet diffuseur placé sous l'orifice d'admission du carburateur. L'eau provenant de l'autre soupape est donc aspirée à travers le double cône Venturi du jet diffuseur et avec l'air et le carburant elle est pompée dans les chambres d'explosion, après avoir été micro-pulvérisée par l'hélice du jet micro-pulvérisateur.When the butterfly valve is fully open in the vertical position, the diffuser jet leaves under the intake port of the carburetor. The water coming from the other valve is therefore sucked through the Venturi double cone of the diffuser jet and with air and fuel it is pumped into the explosion chambers, after being micro-sprayed by the propeller of the micro-sprayer jet.
Le jet diffuseur (fig. 3) peut être placé face à la bouche d'aspiration d'air des collecteurs d'aspiration des moteurs diesel, ainsi qu'en avant des turbos pour les moteurs turboalimentés. The diffuser jet (fig. 3) can be placed in front of the air intake mouth of the suction manifolds of diesel engines, as well as in front of the turbos for turbo-powered engines.
