Definitions
- the present invention relates to an exhaust manifold for a combustion engine internal combustion and can in particular be used profitably in an engine supercharged.
- the exhaust manifold serves to guide the exhaust from the cylinder head to the downstream equipment such as the turbocharger, the elements devices required for aftertreatment of flue gases and the line exhaust (collectively referred to as the engine exhaust face).
- the collector The exhaust system is generally equipped with several tubular ducts whose Inputs are integral with a monobloc input flange. These conduits allow, from the outlet of the different exhaust pipes of the cylinder head, to direct the exhaust gas to a single outlet integral with an outlet flange.
- the exhaust manifold is most often assembled to the cylinder head by means of a screwed assembly which joins the inlet flange with the exhaust face of the breech. A metal seal is inserted between the cylinder head and the inlet flange of the exhaust manifold to ensure a better gas tightness exhaust.
- the first family of exhaust manifolds is obtained from a gravity molding process.
- the collectors are usually cast iron or steel. This family of collectors has the advantage of a better mastery of dispersions and greater latitude in obtaining compact structures.
- Fonts incorporating molybdenum and silicon offer good flowability and machinability properties. They therefore make it possible to obtain inexpensive collectors. On the other hand, the properties of these fonts are strongly altered at high temperatures.
- the current engines, characterized by Very high flue gas temperatures make their use often unsuitable.
- Nickel and chromium cast irons offer better behavior in hot that fonts based on silicon and molybdenum. By cons, their less good flowability and machinability properties result in extra cost on the exhaust manifold.
- steels offer the best performance in terms of performance thermomechanical.
- their poor flow properties require specific and costly industrial resources which have a direct impact on the cost price of the finished product.
- the mastery of the manufacture of these collectors is delicate.
- the second family of collectors is of the welded type.
- the ducts collector can be obtained by stamping thin sheets, by bending of tubes or by hydroforming.
- the materials used for the ducts are ferritic or austenitic steels.
- This family of collectors offers the possibility of designing structures for low thickness, so low inertia, and to assemble materials of different mechanical and thermophysical characteristics. Moreover, nature materials can scan a range of high temperatures. However, the corresponding manufacturing processes give rise to dispersions important geometric
- equipment upstream of the after-treatment device in particular the collector exhaust, must be characterized by a low thermal response time.
- combustion strategies selected to improve the efficiency of the post-treatment of flue gases, in particular for diesel engines, associated with specific powers up increase the average thermal level of the gases exhaust.
- the suspended masses at the exhaust manifold requires an overall stiffening of the exhaust side of the engine. This benefit is generally obtained by by means of several stiffening crutches which make it possible to secure the face exhaust to the powertrain itself.
- the object of the invention is to propose an exhaust manifold having a uniform improved thermomechanical stresses and allow a reduction in vibratory levels of the engine exhaust face, while keeping a good sealing on the exhaust side of the engine between the cylinder head and the manifold.
- the multiple inlet flange is disposed in the central portion of the alignment and the flanges single inlet are arranged laterally on this alignment on both sides of said multiple input flange.
- the connection pipes are present in a rake form whose teeth are constituted by the ducts of inlet ends leading to an inter-duct transom manifold connected to the output end.
- the ducts of at least two adjacent inlet ends are connected between them by a reinforcement veil.
- the reinforcement veil came from material with the ducts and / or the transom manifold.
- reinforcing sails also called palmages
- the presence of reinforcing sails allows on the one hand to provide sufficient rigidity at the level of inter-ducts side to reduce the closure of the bent parts associated with single inlet flange ducts (eg ducts of external substations corresponding to cylinders 1 and 4 for a manifold with four inlet ducts) and on the other hand to increase the section of passage of the efforts at the level of the inter-ducts corresponding to the multiple input flange (for example the inter-duct between the ducts of the internal stations corresponding to cylinders 2 and 3).
- the joining the multiple input flange and said output flange is in the form of an L-shaped assembly block whose branches are respectively carrying the output flange and the multiple input flange.
- the securing of the multiple input flange and of said output flange is presented in the form of an assembly frame with two sides respectively carrying the output flange and the multiple input flange.
- the combination according to the invention of a reduction of rigidity level of all of the inlet flanges and a high rigidity bond between a multiple input flange (cylinder head side) and the output flange (exhaust side) allows to reduce the risk of thermomechanical fatigue cracking and to improve the overall dynamic behavior.
- the performance of a collector according to the invention are further increased with the addition of kerbages at the inter-ducts of the manifold.
- the invention is directly applicable to both types of collectors, the collectors obtained by gravity casting and mechanically welded collectors.
- the exhaust manifold 10 for an internal combustion engine multicylinder illustrated in FIGS. 1, 2 and 3 relates to a first embodiment of the invention given solely by way of non-limiting example, in this case a collector intended to be associated with an in-line four-cylinder cylinder head (not shown) or to a multiple cylinder head having several groups of four cylinders in line by example a V8 engine cylinder head (not shown) which will then be equipped with two collectors according to the invention.
- the collector 10 as illustrated is made of a structure mechanically welded but can without departing from the scope of the invention be obtained by molding of cast iron or steel, the invention being advantageously indifferently applicable to both manufacturing techniques, molding and mechanical welding.
- the collector 10 essentially comprises connection pipes in thin steel sheets of generally rake form, the teeth of which consist of the ducts 21, input 22, 23 and 24 of the gas inlet ends substantially aligned along an axis YY ', the collector further having a general structure almost symmetrical with respect to the median plane Pxz perpendicular to the axis YY '.
- the ducts 21-24 have an orientation along the axis ZZ 'and lead to a tubing of cross-member 12 extending substantially parallel to the axis YY 'to define three inter-ducts 12a, 12b and 12c.
- the tubing 12 is slightly bent in its inverted V medium in the plane Pyz at the height of the inter-ducts 12b as shown in Figure 2.
- the manifold manifolds also have one end outlet having a gas outlet conduit 14 extending substantially parallel to the axis XX 'and arranged symmetrically with respect to the median plane Pxz and opening into the central inter-duct 12b.
- the outlet duct 14 bears a outlet flange 38 of the exhaust gas suitably connected by a downstream exhaust tubing to downstream equipment (not shown) such as turbocharger, peripheral elements of post-treatment of flue gas and line exhaust.
- the flange 38 of generally trapezoidal shape constituted from a plate or steel soleplate has a central through opening of large diameter 37 on which is welded the wall of the duct 14 as illustrated on the FIG. 3.
- three fixing apertures 32 are provided in the flange 38 at the legs 42 (base of small width) and 41 (wide base) to allow mounting and connection with a downstream exhaust tubing (not shown).
- the entry ends ducts 21 to 24 are distributed in free ends, in this case the external inlet ducts 21 and 24 each carrying a fastening flange 26 and 28, and in ends joined together around a multiple flange, in this case the central double flange 30 to which the inner inlet ducts 22 are associated and 23.
- the three flanges 26, 28 and 30 obtained at from steel plates or soles have through openings of large diameter 16, 17, 18, 19 on which are welded the walls of the ducts
- the three flanges are separated from each other and have free faces 27, 29, 31 extending in the plane Pxy.
- the flanges 26, 28 and 30 have through openings 32 of reduced diameter through of which the rods of the wide head fastening bolts (not shown) screwed into threaded bores provided in the cylinder head of the engine receiving the 10.
- the flanges 26, 28 and 30 are mounted on the face cylinder head exhaust with interposition of metal seals way to separately connect each input conduit 21 to 24 to the four corresponding exhaust openings on the cylinder head.
- the inter-ducts 12c communicate with a recirculation duct 34 carrying a flange 36 (similar to the simple flanges 26 and 28) intended to be connected to a recirculation circuit (not shown) of the exhaust gases to the intake duct of the engine cylinders (recirculation circuit also called EGR circuit and intended to reduce the emissions of gaseous pollutants, including NO and NO 2 ).
- a recirculation circuit also called EGR circuit and intended to reduce the emissions of gaseous pollutants, including NO and NO 2 ).
- the multiple input flange 30 is secured to the outlet flange 38 carried by the outlet duct 14 in order to improve the structural rigidity of the collector.
- This configuration can be obtained with a molding process on cast iron or cast steel structures.
- the connection between the two flanges is obtained through a screwed or welded assembly, the latter method being the least expensive.
- This solidarization makes it possible to improve the dynamic behavior of the collector, especially at the level of the mechanical resonances of the motorization assembly incorporating the collector.
- this solidarisation makes it possible to limit the thermomechanical and dynamic stresses at level of the junction between the outlet flange and the inlet ducts.
- all the inlet and outlet flanges 38 of the manifold 10 forms an L-shaped assembly block as shown in FIGS. FIGS. 1 and 3 in which the small width tab 42 of the flange 38 is welded to the middle portion 44 of the double flange 30, which connection may be stiffened or not by a or several brackets at the base of the junction of the two flanges 30 and 38 (in this case it two brackets 46 are provided, on either side of the fastening aperture 39 made in the tab 42, and only one of which is visible in FIGS. 1 and 3).
- Another even more rigid frame block structure in the form of a frame and illustrated to Figures 4 and 5 will be described hereinafter with reference to the collector 100.
- the ducts of at least two adjacent inlet ends are connected between them by a reinforcement veil.
- the reinforcement veil came from material with the ducts and inter-ducts of the transom manifold.
- the collector 10 has reinforcing webs 48, 49, 50 on each of the inter-ducts 12a, 12b, 12c.
- the sails consist of two joined sheets joined together with the adjacent inter-ducts (12b) and welded together and to the inlet ducts (22 and 23).
- the sails are obtained directly by stamping.
- the reinforcing webs are obtained by welding flat products.
- the reinforcing sails are made of material with the transom manifold and the inlet ducts corresponding and obtained directly at the casting.
- reinforcing sails also called wedges
- This characteristic of reinforcing sails allows to increase the stiffness in flexion and the membrane rigidity of the inter-ducts.
- the increase of the resistant section with respect to efforts at the level of inter-ducts 12a and 12c makes it possible to reduce the stresses related to the stresses Membranes in compression.
- the increase of flexural stiffness on the one hand to reduce the closure of the bent parts associated with single inlet flange ducts 21 and 24 in the outer position (bending by the frictional forces at the collector / breech interface and by the expansion at the level of inter-duct 12b) and secondly to improve the tightness of the interface manifold / breech at the separate flanges 26, 28.
- the solicitations are mainly of membrane type and related for the bulk of the dilatations thwarted by the multiple input flange 30.
- the reinforcing sail 49 increases the bending stiffness of the inter-duct 12b, the addition of this decoupled sail of the multiple flange 30 allows, for the most part, to reduce the membrane thermomechanical stress in compression.
- FIGS. 4 and 5 show perspective views of a second mode embodiment of an exhaust manifold according to the invention 100.
- the collector 100 is very close to the collector 10 which it represents, in fact, an interesting variant to the level of the robustness of the connection between the multiple inlet flange and the flange of exit.
- the collector 100 comprises, with two exceptions (the replacement of the double flange 30 by the double flange 102, and the addition of the spacer 104), the same elements as those of the collector 10 and mounted according to a configuration almost identical to that of the collector 10. Consequently the elements identical or nearly identical for the two collectors will keep the same numerical references and will not be described again, the description of the collector 10 given with reference to FIGS. 1 to 3 being for the most part directly applicable to the collector 100 with reference to FIGS. 4 and 5, the changes made in the collector 100 are further specified below.
- the exhaust manifold 100 differs from the manifold 10 by a structural modification namely the strengthening of the connection between the flange multiple input central 102 and the outlet flange 38 by the addition of an L spacer 104 welded between the middle portion of the multiple flange 102 and the leg of large width 41 of the outlet flange 38.
- the assembly block ensuring solarization of the multiple input flange 102 and the output flange 38 is in the form of an assembly frame of rectangular structure whose two sides are respectively carrying the output flange 38 and the multiple input flange 102 and the other two sides are constituted by the L-shaped spacer 104.
- the multiple input flange 102 is in the form of a elongated sole provided with two openings 17 and 18 associated with the two ducts interior entryways 22 and 23 disposed on either side of a central opening through 106 disposed to the right of the outlet flange 38 to limit the section resistant of the dual inlet flange 102 at the central inter-duct 12b.
- the invention is not limited to the exhaust manifolds described but also covers various variants in which in particular the position of the Multiple input flange can be changed from the central position described above with reference to the collectors 10 and 100 and / or the orientation of the outlet flange relative to the multiple inlet flange (described at about 90 ° for collectors 10 and 100) can be modified for example to 180 ° with in particular the use of a U-shaped piece spanning the inter-duct 12b and welded to the flange 102.
- the invention is not limited to 4-duct exhaust manifolds input but also covers, for example, 3, 5 and 6 in which two ducts are secured to a double inlet flange itself secured to the outlet flange, the other ducts being associated with flanges separated.
