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 separat ⁇ ing wall. 12 a chamber 1A is formed within the container, the generation of micro-bubbles taking place within said chamber and the air/liquid suspension also being extracted to the engine from said chamber.
- the separating wall 12 is provided with ap ⁇ e.rt-u es 13, 14 so that the portions 1A and 1B of the container 1,which are separated by wall 12 communicate for permitting free flow of liquid between the portions.
- 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 filling pipe is closed by a cover 4.
- a diffusor 5 Disposed close to the bottom of chamber 1A, which is defined by means of separating wall 12, is a diffusor 5 having a pipe connection 6 extending within the chamber 1A, through the upper wall thereof and being there in connection with the air surrounding the con ⁇ tainer.
- the diffusor 5 consists of a diffusor body of a porous material, the pores of which forming a great number of small ⁇ ir channels densely distributed over the diffusor body, so that air being sucked in via con ⁇ duit 6 are distributed within the diffusor and are dis ⁇ charged within the liquid in the chamber 1A in the form of fine air jets.which on emerging into the liquid form a large quantity of micro-bubbles.
- a conduit 7 opens in the upper wall of the chamber 1A of the container, the opposite end of said conduit opening into the suction line 8 of an internal combustion engine, not shown.
- the conduit 7 which may be a fixed conduit or a hose-, has a uniform cross section or shape along its entire length without any restrictions or obstructions to the free flow of the air/liquid suspension through the conduit.
- the suction conduit 6 of the diffusor 5, which opens above the upper wall of the container chamber 1A is at its free end provided with a restriction in the form of a washer 9 having a hole 10 drilled therein. Further provided at the free end of conduit 6 is an air filter 11 having a low flow resistance.
- the container as well as the conduits and other equipment components are made from a material which is resistent to the liquid which is to be stored in the container, e.g. stainless steel.
- the container 1 is also provided with a level indicator, not shown in the figures, and with the necessary attach- ment means for attaching the container at a suitable location in the vicinity of the internal combustion en ⁇ gine.
- the restrictor washer 9 is preferab- ly made replaceable in order to render possible the insertion of restrictor washer with various degrees of restriction depending on the requirement in each indi ⁇ vidual case.
- 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.
- the diffusor should preferably be made from a porous material, e.g. sintered metallic particles or ceramic sintered material.
- Metal- lie or ceramic icrofilters of the type used in cleaning filters or e.g. flue gas cleaners may thus be used as th *.e* material in the diffusor 5_..
- the embodiment according to the invention differs from the embodiment according to FIG 1 essentially in that the partition wall 12A has been designed as a cylindrical tube which by means of a threaded connection at the top is attached to the under ⁇ side of the container cover 4A, extending downwards to the bottom of the container 1. At its lower portion the tube 12A is provided with apertures 13A through which the chamber 1A, separated by the tubular partition 12A, is connected to the surrounding liquid volume 1B in the container 1.
- a diffusor unit 5 is dis ⁇ posed within the cylinder 12A, near its lower end, and the supply conduit 6A through which air is supplied from the atmosphere to the diffusor -5 is attached to the cover 4A projecting upwards from the top face of the cover 4A, where the projecting tube end 6A is provided with an air filter 11 and a restrictor washer 9 having a hole 10 drilled therein in a manner corresponding to that in the
- the cover 4A is provided with an upwardly projecting connection piece 16 which by means of a hose 7A or some other kind of duct connection is connected to the suction conduit 8 of the engine.
- micro- -bubbles according to the invention takes place in a separate liquid volume within the container partitioned off by the partition wall 12A, a relatively constant concentration of micro-bubbles per unit of volume is ob ⁇ tained, as previously described, regardless of container. size, and also a relatively constant concentration of additive in the air/liquid suspension sucked from cham ⁇ ber 1A into the engine.
- the partition wall 12A having the form of a cy- lindrical tube fastened in the cover 4A, together with the diffusor unit disposed therein, air supply conduit 6A, filter arrangement 11 and connection piece 16, forms a unit which in a simple manner may be transferred from one container to another, and which also may be installed in containers of different size.
- This facilitates the use of containers for the additive, which are designed as non-returnable packages which may be offered for sale in various sizes and which may b suspended in the engine chamber by means of a simple holder.
- said non-returnable package forms such an arrangement for supplying a combustion-promoting liquid medium into the suction line of an internal combustion engine as is intended according to the present invention.
- the cham- ber in which the micro-bubbles are produced may of course include more than one diffusor unit.
- the "bubble production unit" described in connection with FIG 2 may naturally be installed permanently within a container of the type described in connection with FIG 1.
