This invention, relates to a dose measuring device/mixer of fuel, air and water, for internal co bus- tion engines, which will fully replace the traditional carburators of petrol engines, without the need for altera tions in the remainder of the engine.

Its main function, therefore, consists on dosing and mixing the fuel and the water required by the combustion of the engine. The invention allows the use in the mixture with water of any of the traditional fuels em¬ ployed in internal combustion engines, as well as other kind of fuels, air present not e in commercial markets such as methanol among others. The principal object of the present invention is to provide a mixture rich in combustible elements con¬ tained in the air and in steam, envolving a minimum of fuel, exactly the sufficient to allow the explosion of in¬ flammable substance, which guarantees a substantial econ- omy in fuel, when compared with conventional systems, here, frequently, occurs the presence of excessive quantities of fuel in the mixture.

The invention provides the complete burning of the fuel inside the cylinders resulting thereby a total absence of combustion residues, contributting therefore decisively for the effective elimination of atmospheric pollution caused by internal combustion engines.

As shown in the accompanying drawings, the invention consists of a functional assemblage made up basically of four main elements, as follows: a) a small

reservoir 1, hermetically closed, whereto the fuel to be used in the mixture comes in? b) a small duly heated magnetized chamber 2 where the water passing therein is heated under pressure and turned into steam ^* ; c) a nar— -row chamber 3, preferably elongated and preferably ring- shapped in cross section, where evaporation, under pres¬ sure, of the fuel coming from reservoir 1 and optionally the mixture o said fuel with steam coming from magnetized chamber 2, take place? a hollowed body 4, preferably tu- bular, for the passage of at ospheric air, where the mix¬ ture of evaporated fuel, steam and air takes place.

The fuel (petrol, alcohol, etc.) in liquid state, passes through reservoir 1, being afterwards led to chamber 3 _t where it evaporates under heavy pressure , and upon wich it is discharged into the hollowed body 4 where mixture with passing air takes place.

At the same time, the water under pression is made- to pass through the duly heated magnetized chamber ^* 2, preferably elongated and preferably tubular, where evaporation takes place. The resulting steam is afterwards led to chamber 3 _» where it will mix with the fuel under evaporation, or may be led directly to said hollowed body 4- where the mixture with the passing air and with the evaporated fuel, which comes from chamber 3 _» takes place, forming the final inflammable substance.

The _Qose/___ixing Device, can be accomp-lished by means of a small arrangement able to replace with advantage, conventional carburators, particularly those of the bowl- and jet systems, in which the only mixing components are fuel and air.

Seferring now to the drawings, Pig. 1 is a : schematic representation of the invention, where it is shown the functional embodiment made up of the four above mentioned main elements, as follows: a reservoir 1, where the passing of the fuel coming into the system, in liquid state, takes place; a magnetized chamber 2, duly heated, for the evaporation of the water to be used in the mix¬ ture ^* ; a chamber 3 where the evaporation of the fuel co ing from reservoir 1, and optionally the mixture of such evap- orated fuel with the steam coming from the magnetized chamber 2, takes place; and finally a hollowed body 4-, preferably tubular, where the mixture of evaporated fuel and steam with the passing atmospheric air takes place.

Pig. 2, 3 and 4, represent a non-limitative feature of the invention, consisting of a- compact func¬ tional device made up of the fourmain elements referred abovet a reservoir 1, a magnetized chamber 2, a chamber 3 for fuel evaporation and a hollowed body 4.

According to this constructive example, the fuel comes into the system through duct 5, and reachs , through tube 6, the chamber 3 for evaporation. On the other hand, water comes, through duct 7, into magnetized chamber 2, where it is heated up till steam, upon which it is discharged through tube 8 into ehamber 3 or.into the hol- lowed body 4-. Chamber 3 is longitudinally disposed inside the hollowed body 4.

In one side of reservoir 1 there is a tube 9 to discharge the exceeding fuel, which returns to the system. In the upper portion of the hollowed body 4

operates a small, helix-shaped de lector which controls the fuel and/or steam flowing into chamber 3« This deflector is joined to an elongated, preferable cylinder-shaped rod 11, able to move angularly- and longitudinally. Said rod operates inside a tubular body 12, forming with this last one the evaporation chamber 3-

The assemblage made up by de lector 10 and rod- 11 is submitted, by one side, to a screwed pin 13 which controls the longitudinal position of the rod, and by the other side to and antagonistic spring 14, which forces said rod against pin 13.

Fig.2 is a perspective view of the function¬ al assemblage herein described, displaying all its compo¬ nent parts. Pig. 3 is an illustrative sectional view of the hollowed body 4 and of chamber 3* set into said hol¬ lowed body. The atmospheric air, passing through the hol¬ lowed body, in the direction pointed out by the arrows, bumps against deflector 10, forming circles inside the hollowed body 4, forcing the rod 11 to perform an angular movement.

Hod 11 shows lengtwise inclined grooves 15, 16, facing hollows 17 and 18 _. of fuel and/or steam access into chamber 3- The tubular body 12 is disposed in its ree end 19 with smalX exit orifices 20 for the passage of inflammable substance to operate the engine. In the end portion o_f the hollowed body 4 is disposed a butterfly valve 21, controlled by the engine acelerator. A. great¬ er or smaller opening of said valve determines the volume of air that comes into the hollowed body 4. On the other

hand, the current of air bumping against the deflector 10, determines the degree of angular movement of rod 11 inside tubular body 12, which controls the opening by which the fuel and steam enter into chamber _* Such opening depends on the groove's 15, 16 angular position on the movable rod 11, in re^Lation to ho-Hows 17, 18 disposed on the tubular body 12.

Jig. 4 represents an illustrative example of the magnetized chamber 2,where the. ater evaporation takes place. In accordance with such embodiement, a small tube 22, preferably of iron, is externally disposed with two wire windings, 23, 24, one of them operating as a resis¬ tance which heats, to a desired temperature, the water- passing through said tube, while the other is connected to an adequate energetical source, for example, the current of the battery, causing the magnetization of tube 22, A valve 25 is disposed at the entrance of the tube 22, to . control the passing water.

According to the invention, the fuel comes into the reservoir 1, and goes out through tube 6, where it undergoes SL compression on its way to chamber 3 _* Si¬ multaneously, water comes into tube 22 where it is heated until it turns into steam, upon which it is conducted, through tube 8, to chamber 3 where the mixture with the fuel in evaporation takes place, or it is discharged di¬ rectly into the hollowed body 4, where the mixture with the fuel coming from the evaporation chamber and with the atmospheric air passing through said hollowed body takes place. The volume of mixture discharged into the engine depends on the greater or smaller opening of the butter ly

21, disposed at the bottom of said hollowed body 4. hen the water passes through tube 22, to which are associated wire windings 23, 24, occurs, a chem¬ ical phenomenon in which water changes into steam and, together with the evaporated fuel, will give origin to a better combustion, drawing up, from the water, hydrogen and oxigen, creating a better combustion within the en¬ gine cylinders, demanding less petrol or other kind of fuel. Furthermore, the combustion of the fuel does not discharge polluting products and adds to the motor a greater output, once it enters the engine just the volume of inflammable substance demanded by acceleration, which guarantees the complete combustion of the mixture in the . cylinders. Beyond avoiding the discharge of polluting products, and in such way contributing decisively towards the effective elimination of atmospheric pollution caused by internal combustion engines, the invention not only brings substantial economy in fuel, in a percentage ef ec- tively considerable, bulr also allows a longer life for the engine, doing away with whalr happens in conventional systems,, where, as a result of the presence of excessive quantities of fuel in the mixture, the unburnt fuel "washes" the inside of the cylinders,, removing the lu- bricant oil from their walls, and creating, in such way, conditions for the reduction of the useful life of the engine ^* .
