Definitions
- the invention relates to the supply of internal combustion engines with liquid fuels.
- the invention also relates to a method for producing such a system.
- Liquid additive reservoirs having a small volume in comparison with that of the fuel reservoir, have been designed for mounting on, in or close to the fuel reservoir of diesel motor vehicles.
- patent application DE 10112361 discloses a fuel reservoir in the form of a saddle including within it an additive reservoir that is situated close to the pump serving to balance the fuel level in different parts of the reservoir.
- Such a system is compact but has the disadvantage that the reservoir for the additives has to be produced separately and then fixed inside the fuel reservoir. Moreover, such a system is limited to additives that have to be metered into the fuel reservoir itself.
- the object of the invention is to provide a compact but all-purpose fuel system that is equally suited to the production of supply systems for engines operating with light, volatile hydrocarbons and to the manufacture of supply systems for engines operating with heavy hydrocarbons, and which makes it possible to meter an additive not only into the fuel reservoir itself but also into any other part of the fuel system, the engine or the ⁇ exhaust system, etc.
- the invention relates to a fuel system for an internal combustion engine operating with a liquid fuel and comprising a fuel reservoir intended for the said fuel as well as an additive reservoir comprising a chamber that is formed in a concave recess of the wall of the fuel reservoir.
- the fuel system is an assembly of compartments that are intended to be incorporated in a motor vehicle or a stationary power installation and -that have the main function of storing, purifying, measuring or transporting a fuel intended for supplying a heat engine .
- the automotive vehicle can be a motor vehicle (car, lorry, motorcycle, river boat, sea-going vessel or an aeroplane, for example) or a vehicle dedicated to a track (for example a railway locomotive) .
- the stationary power installation can for example comprise the motor of an electricity-generating unit or a machine-tool motor.
- a fuel is understood to denote a hydrocarbon that is suitable for supplying internal combustion engines.
- liquid hydrocarbon denotes a hydrocarbon that, under normal conditions of use for the engine, exists in a liquid state in the fuel reservoir of the fuel system.
- volatile liquid hydrocarbon denotes a liquid hydrocarbon (according to the definition stated above) that has a saturated vapour pressure greater than 1 bar at 293 K (20°C) .
- Volatile liquid hydrocarbons commonly used for supplying heat engines of motor vehicles are those sold commercially under the name “petrol” and intended for so-called “explosion” spark-ignition heat engines.
- heavy liquid hydrocarbon denotes a liquid hydrocarbon that has a saturated vapour pressure below 1 bar at 293 K (20 °C) .
- Heavy liquid hydrocarbons commonly used for supplying heat engines of motor vehicles are those sold commercially under the names “gasoil” or “gazole” and intended for compression- ignition heat engines operating with the diesel cycle.
- the additive reservoir is produced in one piece with the fuel reservoir and the assembly is denoted by the general term "reservoir” in the following paragraphs .
- This reservoir can be made of any material compatible with each of the liquid hydrocarbons that it is likely to contain. This material must be chemically inert at the same time to volatile liquid hydrocarbons and to heavy liquid hydrocarbons at normal pressures and temperatures of use. It can be made of plastic or metal. Plastics give good results within the context of the invention.
- the reservoir can be manufactured by any suitable means.
- the reservoir is manufactured by a moulding operation.
- the material of the reservoir must be chosen from those permitting manufacture by moulding.
- Thermoplastic materials are well suited to this end.
- a thermoplastic material denotes any thermoplastic polymer, including thermoplastic elastomers, as well as their mixtures.
- the term "polymer” denotes homopolymers as well as copolymers (in particular binary or tertiary) . Examples of such copolymers are, in a non-limiting manner: random distribution copolymers, sequenced copolymers, block copolymers and grafted copolymers.
- thermoplastic polymer or copolymer Any type of thermoplastic polymer or copolymer is suitable of which the melting point is below the decomposition temperature.
- Synthetic thermoplastic materials that have a melting range extending over at least ten degrees Celsius are particularly well suited.
- such materials there exist those that have a polydispersion of their molecular mass.
- a mixture of polymers or copolymers can also be used, as well as a mixture of polymeric materials with inorganic, organic and/or natural fillers such as, for example, but not in a limiting way: carbon, inorganic salts or other derivatives, natural fibres, glass fibres and polymeric fibres. It is also possible to use multi-layer structures consisting of stacked integral layers comprising at least one of the polymers or copolymers described above. Vinyl polyhalides and polyolefins are generally preferred.
- a polymer that is often employed is polyethylene. Excellent results have been obtained with high-density polyethylene (HDPE) .
- HDPE high-density polyethylene
- the reservoir of the system according to the invention is generally connected to a filling tube intended for the introduction of liquid fuel into the fuel reservoir.
- This tube can be manufactured separately and then added to the reservoir to which it is attached by any suitable means, for example by welding or gluing.
- the filling tube is moulded in one piece with the reservoir.
- the reservoir includes a recess in its wall, this recess being concave on its face directed towards the outside of the reservoir.
- the shape of the recess is not critical for defining the invention. It can equally well have a curved shape (for example the shape of a portion of a sphere or an ovoid shape) , a conical or frustoconical shape or a polyhedral shape. It is preferred to give it a curved shape, this being regular or irregular.
- a chamber is formed in this concave recess that forms an integral part of the additive reservoir.
- This chamber is advantageously provided with a metering system that preferably comprises an injector that is connected to an injection pump and that emerges at the place provided for dosing the additive (reservoir, engine, exhaust etc) .
- the injector and the injection pump can each be located inside the recess or outside this.
- the metering system preferably includes a syringe pump s ch as described in application FR 0320880.8 in the name of the Applicant.
- the chamber of the additive reservoir communicates with the fuel reservoir by means of an opening provided through it.
- the chamber preferably includes a system for metering the additive from the chamber into the reservoir, via the aforementioned opening, the said metering system advantageously comprising a pump and an injector passing through the aforementioned opening.
- the metering system has the function of distributing the additive into the fuel reservoir, it does this for example in a quantity that is a mathematical function (normally, but not necessarily, a proportional function) of the instantaneous consumption of fuel by the engine.
- This quantity is generally calculated by an on-board computer or a specific calculator.
- metering can be carried out once, just after filling, according to the quantity of fuel introduced during filling.
- the computer or calculator is advantageously connected to a device for detecting the opening and closing of the fuel filling system.
- a device can comprise an electromagnet which is connected to a moveable component (a stopper strictly speaking or any other manual or automatic closing system) and which changes polarity between its open and closed position.
- This difference of the polarity state is detected by the on- board computer which memorizes the contents of the reservoir at the moment it is informed of this. If the position of the stopper when closed corresponds to a rest situation for the computer, it is able to calculate a difference of fuel volume introduced between the moment when the system is activated and the moment when it becomes stable again. This volume serves as a basis for calculating metering (performed after closing the stopper) necessary to maintain a constant additive concentration.
- the aforementioned chamber is intended to serve as a reservoir with any additive, preferably a pasty or liquid additive, that can be intended to be added directly to the fuel as previously stated, but can also be intended to be introduced into the engine or the exhaust gases, etc.
- any additive preferably a pasty or liquid additive
- the system according to the invention is intended for a diesel engine, it advantageously comprises a composition, dissolved in a hydrocarbon solvent, of a catalyst for the low-temperature combustion of carbonaceous solid particulates produced by the incomplete combustion of the heavy hydrocarbon in a compression-ignition engine.
- liquid additives that are suitable for this variant are iron and cerium salts in a hydrocarbon solution.
- the chamber of the additive reservoir is advantageously closed by a lid of any shape.
- the latter consists of a plate intended to be fixed to the periphery of the recess.
- the material of which the lid is made it not critical for the definition of the invention.
- the lid should be made of a material that enables it to withstand the chemical and mechanical stresses to which fuel systems of internal combustion engines are normally subjected during normal use. It can for example be made of metal or of a synthetic resin. In the case of a synthetic resin, this is advantageously the same as that of the fuel reservoir.
- a device for metering the additive injection pump for example
- the object of this conductor is to supply the device with electricity. If it is a multi-channel conductor, it can optionally also connect the metering device to an engine management calculator or any other control component.
- the lid must be hermetically sealed to the chamber. This can be achieved by any suitable means and can be of the removable or non-removable type. Means of attachment that can be used in the system according to the invention comprise welding, gluing and crimping. As a variant, the lid is a circular lid that is screwed onto a threaded circular zone of the periphery of the recess .
- the system according to the invention also preferably includes a filling device for introducing the additive into the chamber.
- This filling device can comprise a filling tube that can either communicate with, or emerge in, the filling tube of the fuel reservoir, or can be independent of this.
- the filling tube of the fuel reservoir and the filling tube of the additive reservoir are in communication, the filling tube of the additive reservoir emerging into the filling tube of the fuel reservoir.
- the system according to the invention also advantageously includes a tube for degassing the additive reservoir that also preferably ends in the filling tube of the main fuel reservoir, beside an orifice for guiding a nozzle for dispensing fuel.
- a stopper that is common to the ends of the filling and degassing tubes advantageously enables these tubes to be closed in a more or less leakproof manner, apart from periods when this additive reservoir is being filled.
- the tube for degassing the additive reservoir can be provided, at its upper part, with means for visually indicating an overflow state to an operator, at the end of the process of topping up the additive through the filling tube.
- These means can consist, for example, of a float placed in the degassing pipe that rises to the upper orifice of this pipe as soon as the reservoir is filled with additive and threatens to overflow through this pipe.
- the degassing tube according to this variant of the invention is preferably provided with an excess pressure and a reduced pressure safety system.
- the aim of this system is in particular to be able to remove air present in the additive reservoir during filling (excess pressure safety) and to replace the volume of additive, progressively consumed, by air during the operation of the vehicle (reduced pressure safety) .
- this system includes a valve that only opens beyond a given pressure threshold (for example above 120 mbar) , this being to prevent leakages of additive and unwanted ingress of liquid, dust etc.
- the invention also relates to a method for manufacturing a fuel system as previously described, wherein:
- a reservoir for the said fuel is manufactured, of which the wall has a recess that is concave on its outer face; a lid is manufactured; the said lid is hermetically attached to a peripheral edge of the aforementioned concave recess, so as to form a chamber; an additive is introduced into the chamber before or after the lid is attached; and the chamber is connected to a system for metering the additive before or after the additive is introduced into the chamber.
- the terms used have the same significance as those employed above for describing the fuel system.
- the reservoir and the lid are made of plastic, such as previously described, and, in a particularly preferred manner, of thermoplastic, which enables them to be manufactured by moulding. Any type of suitable moulding can be employed. Moulding by blow-extrusion and moulding by blow-injection are especially recommended for the manufacture of the reservoir and, in particular, moulding by blow- extrusion.
- the lid it is preferably injection-moulded.

- This fuel system comprises a fuel reservoir made of polyethylene, of which the wall 1 has a recess 2 covered by a plate 3 delimiting a chamber 4.
- the chamber 4 serves as a reservoir for a liquid additive for the heavy hydrocarbon, the said additive comprising a catalyst for the combustion of carbonaceous particulates or dust that are produced during the combustion of the heavy hydrocarbon in the engine chambers.
- the chamber 4 is connected to the reservoir by a metering system comprising an electric injection pump 5 that is attached to the plate 3 and immersed in the liquid additive (not shown) .
- a pipe 6 connects the pump 5, through the plate 3, to an injector 7 that penetrates into the wall of the reservoir 1 through an opening (not shown) .
- the pump 5 is supplied with electricity by means of an electric conductor 8 passing through the plate 3 in a leakproof manner.
- a pipe 9 emerging in an opening (not shown) of the plate 3 acts as a tube for filling the chamber 4 with additive.
- a second pipe 10 acts as a tube for degassing the additive reservoir when the latter is being filled.
