Definitions

  • the present invention relates to a method and a device for supplying a combustion-promoting liquid medium into the suction line of an internal combustion engine. It is previously known that by supplying combustion-pro ⁇ moting liquid additives into the suction line of an in- ternal combustion engine, a more efficient combustion, a decreased fuel consumption, cleaner waste gases and a higher engine power may be achieved.
  • Known devices for this purpose include a closed container for the liquid having diffusor means disposed in the lower part of the container, said diffusor means being connected with the ambient air by means of a conduit for supplying air and discharging air bubbles into th ⁇ e liquid within the con ⁇ tainer.
  • the container is connected with the suction line of the internal combustion engine by means of a conduit opening into the upper part of the container.
  • the combustion-promoting medium should be supplied into the engine in a certain concentration and in a very finely divided state together with the oxygen required for the combustion.
  • O PI micro-droplets, suspended in the gas extracted from the container depends on the one hand on the quantity of micro-bubbles produced per unit of time within the liquid in the container, and on the other hand on the air volume above the liquid level in the container.
  • the result is that by using a diffusor unit which due the vacuum prevailing at the suction side of the engine dis ⁇ charges a certain quantity o-f bubbles per unit of time in the liquid, the concentration of micro-droplets in the extracted gas is highly dependent on the air volume above the liquid level in the container.
  • This air volume is subject to variations partly depending on changes in the liquid level in the container, partly to a high de ⁇ gree depending on the container size.
  • the containers are manufac ⁇ tured in varying size series, e.g. in volumeseries of e.g. 1 litre, 2 litres, 5 litres etc.
  • This involves un- desirable variations with respect to the concentration of the additive in the form of micro-droplets suspended in the extracted gas.
  • this problem can be solved by providing a complete unit for each -cylinder and thus achieving a largely unchanged concentration of additive in the extracted gas.
  • this solution is unacceptable and results in extensive piping and space problems in connection with installa ⁇ tion in the engine house, and also in maintenance prob ⁇ lems.
  • the container size is adapted to existing size intervals for the engines, resulting in said variations with respect to the concentration of additive in the extracted gases.
  • the object of the present invention is to provide a simple method and means for supplying the suction line of an internal combustion engine with a combustion- ⁇ promoting liquid medium, the concentration of micro- -droplets of the additive in the gas being sucked into the suction line of the engine being maintained essen ⁇ tially constant or within acceptable limits, regardless of the size of the container for the additive and using one and the same unit for the production of micro-bubb ⁇ les.
  • FIG 1 shows a section through a first-embodiment of an arrangement for carrying out the method in accordance with the invention
  • FIG 2 shows a section through a container having a bubble chamber. which may be detachably inserted into the container, said bubble chamber including a bubble production unit and an extraction arrange ⁇ ment.
  • the vacuum on the suction side of an internal combustion engine is utilized in a manner known per se for supply ⁇ ing a combustion-promoting liquid medium into the suc ⁇ tion line. Due to the vacuum ambient air is thus sucked into a container, which contains said liquid medium, and is distributed within the liquid by means of a diffusor, the air bubbles formed absorbing liquid drop ⁇ lets which, suspended in air, are sucked into the suc ⁇ tion line of the internal combustion engine and mixed with the fuel air or with the fuel/air mixture, and is supplied into the combustion chamber for promoting the combustion.
  • the combustion-promoting liquid is supplied into the suction line and into the combustion chamber in a condition as finely divided as possible in order to contribute to the greatest possible extent to efficient combustion. It is also desirable that the atomized liquid be supplied in a high concentration so that the total reaction sur ⁇ face of the combustion-promoting medium supplied becomes as large as possible and so that the concentration of additive in the form of micro-droplets suspended in the gas sucked from the container into the engine, is kept essentially constant at a desired value, suitable for the engine involved, regardless of the volume of the container for said additive.
  • this is achieved by making the diffusor discharging the air bubb ⁇ les within a volume of liquid in the container, which is separated from the remaining container liquid, the air suspension of said medium being sucked into the internal combustion engine from the space aboversaid separate liquid volume in the container.
  • this is brought about by arranging a single separating wall in the container, said wall separating a liquid volume wherein said dif ⁇ fusor is arranged and into which said suction conduit opens. The quantity of micro-bubbles- are thus discharged within a liquid volume being subject to very moderate variations regardless of the size of the container as such.
  • the separating wall is designed as a vertical cylinder, open at the bottom, and containing a bubble generating diffusor, the upper end of said cy ⁇ linder being fastened to the filling cover in which also the conduit for supplying ai -to the diffusor as well as the suction line for air/liquid sus-pension open.
  • the cylindrical separating wall thus form a complete bubble generating unit which, by means of the container filling cover is detachably fastened in the container and may be attached to an optional container.
  • FIG 1 illustrates, schematically an arrangement for carrying out the method according to the invention.
  • the arrangement consists of a closed liquid container 1' for the combustion-promoting liquid 2.

  • a filling connection 3 for filling the container with liquid to a predetermined level is provided in the upper wall above container section 1B, i.e. that section of the container which by means of a wall 12 is separated from chamber 1A in which the generation of micro-bubb ⁇ les takes place.

  • the restrictor washer 9 may be replaced by a restricting nozzle which is step- -wise or continuously adjustable thereby facilitating adjustment of the flow restriction to a suitable value in a simple manner.
  • the diffusor 5 used in the described arrangement according to the invention is, as mentioned, designed to finely dividing the air into a number of densely distri ⁇ ubbed fine air jets.

Abstract

Procede et dispositif permettant d'introduire un liquide (2) ameliorant la combustion dans la conduite d'alimentation d'un moteur a combustion interne sous l'influence de l'aspiration cree par le moteur. Dans un reservoir (1) destine au liquide (2) est disposee une cloison de separation (12) isolant une chambre (1A) dont la partie inferieure contient un diffuseur (5), ce diffuseur etant en communication avec l'environnement par l'intermediaire d'une connexion (6). Une conduite (7), dont l'autre extremite se termine dans la ligne d'alimentation (8) d'un moteur a combustion interne, debouche dans la partie superieure de la chambre (1A). Des micro-bulles se produisent dans le volume de liquide dans la chambre (1A), depuis laquelle la suspension air/liquide est aspiree vers le moteur a combustion interne. Ceci permet de maintenir la concentration en additif dans la suspension air/liquide extraite sensiblement constante ou dans des limites acceptables, quelles que soient les dimensions du reservoir contenant l'additif. Selon une variante du dispositif selon l'invention, la cloison de separation (12) est concue comme un cylindre sensiblement vertical (12A) qui est assujetti a sa partie superieure au couvercle de remplissage (4A) du reservoir et forme, avec ce couvercle, une 'unite de production de bulles' complete qui peut etre separee du reservoir et comprenant le diffuseur (5) avec les moyens de raccordement a l'aspiration du moteur.
