Definitions
- the present invention relates to an exhaust gas recirculation device for an internal combustion engine, such as in particular a motor vehicle engine, such a device also being known under the abbreviated designation "EGR" (Exhaust gas recirculation).
- EGR exhaust gas recirculation
- the air intake system of an internal combustion engine comprises an air inlet duct, of circular section or other, and a multi-outlet distributor which follows the air intake duct. air and which directs the air towards the different cylinders.
- the problem is to introduce the exhaust gas into the air intake duct such that these gases form with the admitted air a homogeneous mixture, before entering the tundish.
- the French patent application 2871530 provides, for the recirculation of the exhaust gas of an internal combustion engine, a dual admission of these gases, on either side of the air intake duct. Two symmetrical gas streams are thus injected into the inlet duct, at two distinct points, these gas veins opposing each other colliding with each other by dissipating part of their energy, before to form, in the inlet duct, two adjacent contra-rotating vortices, that is to say rotating one in the opposite direction to the other.
- This known embodiment retains disadvantages:
- the present invention aims at remedying the disadvantages described above, and is therefore intended to eliminate homogeneity defects in the mixture of exhaust gas and air, particularly in the case of oblong section intake ducts and of splitters with flattened entry and / or plenum, while retaining the advantages of the vortex-creating devices, by a simple technical solution in its structure and manufacture7 * and making it possible to use all the kinetic energy of the exhaust gases while by preserving the wall of the intake duct.
- the subject of the invention is an exhaust gas recirculation device for an internal combustion engine, and more particularly a recirculation device comprising, inside an air intake duct which is followed by a multi-outlet distributor, means for introducing the recycled exhaust gases, creating a vortex circulation of these gases for mixing with the fresh air admitted, upstream of the inlet of the distributor, particularly for an oblong section air intake duct and / or a distributor with a flattened inlet and / or plenum, the device being adapted to inject the exhaust gases by forming two counter-rotating adjacent vortices, which is self-rotating; - decisionsts up to the outlets of the distributor, this recirculation device being essentially characterized by the fact that it comprises a double tubular mixer nozzle, in the form of two complete or incomplete tubular tips, disp dared side by side and symmetrically inside the air intake duct, and an exhaust gas supply duct which is unique and common to the two tubular mixer nozzles, this common supply duct being located
- the inventive idea is to inject the exhaust gases from a single injection point simultaneously into two adjacent tubular elements to create two opposing vortices that are self-sustaining in the conduit of air intake, especially if it has an oblong section which corresponds, overall, to the envelope of the two tubular elements contiguous.
- the two vortices extend inside the tundish, to the outlets of the tether, and they interact by training one another and balancing each other.
- the two tubular mixing tips may be axes parallel to each other, and to the central axis of the air intake duct.
- it is possible to more precisely direct the two contra-rotating vortices in particular by providing that the two tubular mixing tips have diverging axes, which also form an angle with the central axis of the air intake duct. This allows in particular to create two divergent vortices, in approximate correspondence with the flattened and flared plenum plenum, the risk of a "bonding" on one side of the splitter is thus excluded.
- the structure and assembly of the recirculation device according to the invention remain simple, since the tangential duct for supplying the exhaust gases remains unique and common to the two tubular mixing tips, and that, moreover, this common duct
- the exhaust gas supply may form a single piece with the double tubular mixer nozzle.
- the attachment of this piece to the air intake duct is achievable by means of an annular fixing skirt, for example welded, which connects the outer wall of the common duct for supplying the exhaust gases to the outer wall. the air intake duct.
- the two tubular mixing tips may each result from a substantially semi-cylindrical deflecting wall, this double deflecting wall being positioned in front of the outlet of the common conduit for supplying the exhaust gases. , such an incomplete tubular configuration being also able to create two contra-rotating vortices.
- the two semi-cylindrical deflector walls attached to one another but separated from the common conduit for supplying the exhaust gases, must be connected to the inner wall of the air intake duct. , by means of brackets.
- the two substantially semi-cylindrical baffle walls may result from a single sheet properly bent and bent, while reducing the pressure losses of the fresh air flow.
- the fixing lugs two or three in number, advantageously have on their outer edge retaining claws provided to grip the inner wall of the air intake duct.
- the assembly of the two semi-cylindrical deflector walls and fixing lugs is feasible from a single sheet, folded and bent.
- the invention provides an exhaust gas recirculation device which not only improves the homogeneity of the mixing of these gases with the fresh air admitted, but which is furthermore of manufacture and service. a simple and economical assembly, and does not create energy losses.
- the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of example, a few embodiments of this exhaust gas recirculation device for an internal combustion engine.

- the end portion of the pipe 2 for supplying the exhaust gases can support the two tubular mixing tips 10 and 11, the pipe 2 being itself held by means of an annular fixing skirt 13 which connects the outer wall of this pipe 2 to the outer wall of the air intake duct 3.
- the annular fixing skirt 13 may be welded to the duct 2 for supplying the exhaust gases. 'exhaust.
- the hot combustion gases brought by line 2 along arrow F1 are distributed equally in the two tubular mixing tips 10 and 1-1, in which they arrive tangentially, then these gas are guided circularly against the inner walls of these tips 10 and 11, while being driven forward by a portion of the fresh air flow F2.
- the exhaust gases form, inside the two tubular ends 10 and 11, two contra-rotating vortices 14 and 15, while mixing with the fresh air.
- These two eddies 14 and 15 of exhaust gas extend, by an effect of inertia, beyond the end pieces 10 and 11, into the inlet 5 and the plenum 8 of the distributor 6.
- the recirculation device 9 represents a variant of the recirculation device 9, in which the two tubular mixing tips 10 and 11, always arranged side by side inside the air intake duct 3, have respective diverging axes 16 and 17, respectively; that is to say the axes which deviate towards the downstream, and which also form both an acute angle A with the central axis 18 of the air intake duct 3.
