Definitions
- the invention relates to a set of filling and degassing pipes of an additional fluid reservoir for an internal combustion engine, these pipes being adaptable in length and / or orientation.
- the invention relates to the filling pipes and degassing of the tank of a nitrogen oxides reduction fluid, called "SCR", for the exhaust gas of a diesel engine vehicle.
- SCR nitrogen oxides reduction fluid
- the adaptability of these tubes allows a workshop installation on almost all vehicles.
- the invention also relates to a motor vehicle with an internal combustion engine, in particular a diesel engine, equipped with such a set of pipes.
- the invention relates to the field of tanks for containing an additional liquid for the fuel or the exhaust gas of an internal combustion engine.
- a particularly suitable application relates to the additional liquid called "SCR” (acronym for "Selective Catalytic Reduction” in English terminology) used for the selective reduction of nitrogen oxides NOx (usually NO and NO 2 ) present in the exhaust gas. diesel engines.
- SCR selective Catalytic Reduction
- Such an SCR tank also comprises means for connecting a liquid filling pipe SCR and a degassing pipe which makes it possible to evacuate, during filling, the air or the gas contained in the tank SCR.
- This gas to be discharged is partially produced by the hydrolysis of the liquid SCR under the influence of temperature, according to the formula:
- the degassing tubing intended to evacuate the air and the urea and ammonia vapors thus produced, has a minimum internal diameter, of the order of 9 to 10 mm, to achieve evacuation quickly without overpressure. .
- the liquid filling port SCR On the bodywork of a vehicle, the liquid filling port SCR is generally disposed on the vehicle body, in the same hatch and near the fuel filling port, while the tank of SCR liquid is placed in a lower part of this vehicle.
- the liquid filling pipe SCR thus connects the tank SCR to the filling port at the body via a connecting ferrule, while the degassing tubing connects the reservoir SCR to an end portion of the filler neck (located near the filler port).
- a filler box 7, arranged on the body "C" by internal connection, has on its internal face 7i connecting blocks 7a to the filling pipes 1 and 4 respectively of fuel in the fuel tank 3 ( arrow F1) and additional liquid in the tank SCR 6 (arrow F5).
- the housing 7 houses the filling holes (not visible).
- the degassing tubes 2 and 5 respectively allow the evacuation of the gases from the fuel tank 3 (arrow F2) and from the gases of the additional liquid reservoir 6 (arrow F6).
- These pipes 1, 2, 4, 5 are fixed along the wheel passage 8 on the inner side.
- the modularity makes it possible to adapt different silhouettes on the same platform and thus brings more rationality to the assembly lines.
- the liquid tanks are part of the modular platform, while the filling and degassing pipes are part of the bodywork, therefore the silhouette.
- the invention aims to allow adaptation in length and angle of this manifold to different couples "platform and silhouette", while achieving a rapid evacuation and without overpressure of the gases while maintaining a minimum internal diameter to this manifold .
- the degassing tubing of a SCR installation must be able to easily evacuate the gases.
- the liquid SCR evaporates easily and can crystallize at the connections between the pipes and the filler box, in particular when the adaptation of the pipes to the tanks is not optimized.
- the invention provides for the use of SCR fluid tubes adapted to deform while respecting the technical flow constraints due to this fluid. More specifically, the present invention relates to a set of pipes for an additional internal combustion engine fluid, comprising filling and degassing pipes coupled on the one hand to an additional fluid reservoir and, on the other hand, on the other hand, means for connection to filling ports, in particular accessible from the outside of the vehicle when the vehicle embeds these tubings associated with the tank.
- Each tubing has an internal axis defining a surface of internal section limited by the intersection between a plane perpendicular to the axis and the tubing.
- the filler pipe and the degassing pipe each comprise at least one rigid part and at least one so-called adaptable portion of semi-rigid structure capable of providing a variable length and / or angular orientation while retaining, for example, any minimum section of this adaptable portion, a sectional area substantially equal to a section surface located in the rigid portion.
- the semi-rigid part of the pipes can thus be adapted to different positions of the connection means to the filling orifices without having to change tubings.
- the invention also relates to any system integrating the tank with the tubing assembly described above associated with it, and any motor vehicle, with a motor (propulsion) thermal, gasoline or diesel type, integrating said system.
- semi-rigid partite a portion of tubing composed of deformable zones distributed homogeneously in this portion, so as to be able to lengthen and curve respectively by a few centimeters (in particular up to 4 to 5 or 6 centimeters) and a few degrees (in particular up to 5 to 10 degrees), and rigid zones distributed in addition to the deformable areas to maintain a deformation of these areas without creating local internal voltage.
- the adaptable part comprises a bellows, this bellows has a periodic series of folded accordion-shaped surfaces defining a sequence of minimum sections remaining substantially constant during an adaptation in length and / or orientation of the bellows;
- the adaptable part of the bellows is able to lengthen by at least 10%
- At least one spacer is also inserted in the adaptable part
- the adaptable portion is a spiral wound tubing, such a tubing also allows a position adaptation by a variation in length and / or curvature without substantially altering the sectional area of the tubing;
- the adaptable part comprises an extensible sleeve consisting of a tight mesh of metal braids
- the adaptable part has walls made of a material based on stainless steel, such a material being advantageously able to withstand the corrosion of acids or compositions derived from urea;
- the adaptable portion is secured to the rigid portion by mechanical means or adhesion selected from an adhesive joint, a thermoformed ring and a tight fitting;
- the additional fluid is a selective catalytic reduction fluid of the SCR type.
- FIGS. 2a and 2b are perspective and sectional views of the filling and degassing pipes of an SCR tank with adaptable parts comprising a compressed bellows;
- FIG. 4 is a front view of an example comprising an adaptable portion of the SCR filling pipe constituted in spirals, and
- FIG. 5 a perspective view of a bellows filler neck mounted at two angles of different orientations.
- the filling pipe 14 comprises in this figure two fixed length portions 20 connected - via thermoformed rings 16 - with a portion of variable length 21 formed by a bellows.
- the degassing tubing 15 has two fixed length portions 22 coupled via thermoformed rings 16 by a variable length portion 23 formed by a bellows.
- These two tubes 14 and 15 are advantageously made of high density polyethylene "HDPE".
- the filler neck 14 extends to the ferrule 25 for coupling to connection means of a filler box filling port (see reference 7 of Figure 1).
- the tubing 14 is fixed by a lug 27 to the vehicle body and by the clip 26 to the fuel filler neck (referenced 1 in FIG. 1), the ferrule 25 being attached to the means by the fuel filler box (reference 7 in Figure 1).
- FIG 2b shows, in section, the bellows 23 of the degassing tubing 5 of Figure 2a.
- the bellows 23 has an internal axis XX 'and an internal diameter d2 equal to the internal diameter d1 of the rigid portion.
- This bellows is tightened and the length "L1" of the bellows 23 is substantially minimal, the bellows 23 then being compressed.
- This diagram also similarly illustrates the bellows 21 of the filler neck 14 in the compressed state.
- the bellows 23 consists of a set of convolutions 30 forming a succession of folded surfaces accordion defining a succession of vertices 31 pointing outwardly of the bellows 23, and roots 32, oriented towards the inside 23i of the 23.
- the set of roots 32 forms a series of minimum sections defining an inner surface 33 (dashed lines ⁇ arranged in alignment with the inner surface 34 of the fixed length portion 22.
- the alignment of these surfaces 33 and 34 forms a continuous cross-sectional area offered to constant-size vapor flow, liquid or SCR gas, which eliminates or reduces the risk of turbulence and pressure drop.
- Figure 3a shows a diagram of the filling pipes 14 and degassing 15 similar to that of Figure 2a, but wherein the bellows 21 and 23 are stretched.
- the elongation is of the order of 40 mm for the two tubes 14 and 15. This elongation thus allows great modularity within a styling chain for different silhouettes.
- Figure 3b shows the bellows 23 of the degassing tubing 15 seen in section once stretched.
- the length "L2" of the bellows 23 is substantially elongated about 40 mm from its compressed conformation of Figure 2b, an elongation rate of up to about 20% in the example.
- elongation rates can vary between 10 and 30% or more.
- Figure 4 shows the diagram of an adaptable portion formed of a pipe 40 consisting of a series of spiral convolutions 41 contiguous and inclined.
- This spiral tube 40 ends with two linear ends 42 connected to the rigid parts 20 via thermoformed rings 16.
- the spirals 41, the linear parts 42 and the rigid parts 20 have sections of substantially identical surface.
- the adaptable portion allows, according to the invention, not only to obtain a length of tubing 14 or 15 variable in length, as shown in the previous figures, but also in curvature to allow adaptation in orientation.
- FIG. 5 Such an angular adaptation is illustrated by the perspective view of Figure 5 which relates to the filler pipe 14 can be mounted on a filler box 7 (see Figure 1), in two different directions corresponding to two positions "A" and “B” forming an angle “a” in the illustrated example.
- the adaptable part 10 is formed of a sleeve that can bend to deport the tubing 14 by an angle "a", for example equal to 7 to 8 degrees , without creating internal mechanical tension.
- Such a sleeve 10 is formed in the example illustrated by a tight mesh of metal braids, but may also be constituted by the bellows 21 ( Figures 2a and 3a), the spiral pipe 40, or a metal spiral covered with a envelope made of flexible material.
- This angular adaptation is obtained by stretching on one side and compression on the opposite side of the sleeve 10, for example convolutions 30 (FIG. 2b) or 41 (FIG. 4), respectively of the bellows 23 (or the bellows). 21) and the spiral tubing 40.
- the invention could be used in the case of a fuel engine, placed in a building, in a locomotive or in a ship, and also requiring a reservoir and additional liquid lines, particularly SCR type.
