Definitions

  • the invention relates to an intake manifold with an integrated exhaust gas recirculation, which a connection for the exhaust gas and supply openings for the different suction channels has, according to the preamble of claim 1.
  • the object of the invention is therefore a suction pipe with an integrated exhaust gas recirculation to create, in which the thermal from the exhaust gas recirculation The load on the intake manifold is low.
  • This task is characterized by the characteristics of the Claim 1 solved.
  • the suction pipe according to the invention has the known structure with inlet, collecting space, from this outgoing suction channels and outlets to the cylinders.
  • the outlets can usefully be designed as a cylinder head flange.
  • the Intake pipe can be used for a row arrangement, V arrangement or any other Arrangement of the cylinders can be provided. It is also possible to have multiple collection rooms to provide, which are assigned to the respective groups of suction channels.
  • the intake manifold has a connection for the exhaust gas recirculation.
  • An exhaust pipe leads the exhaust gas to supply openings, each of which is through the suction channels influenced flow area of the intake air are arranged.
  • exhaust gas can be supplied separately to each cylinder, whereby a desired, ensures, in particular, uniform distribution of the exhaust gas over all cylinders becomes.
  • Valves can be provided in the supply area of the exhaust gas, the one cylinder-selective exhaust gas introduction depending on the timing of the individual Allow cylinders.
  • the flow area influencing the suction channels understood the area of extensive assignment of the supplied exhaust gas to a suction channel. So below that is not just the volume of the suction channel to understand yourself.
  • the feed openings can also be in the volume of Collecting space and in the vicinity of the suction openings formed by the suction channels, which open into the collecting room, can be arranged.
  • This essentially means a clear assignment of the exhaust gas to the individual suction channels possible.
  • connections and Exhaust pipes are provided in the intake manifold.
  • the connections and the exhaust pipe create a design advantage in the construction of the intake manifold Scope as there are fewer constraints when laying the cables in the collecting room by other components, such as. B. the injectors, cylinder head cover, generators, Pumps, the fuel rail or screwdriver clearances are observed have to.
  • Another advantage is that the exhaust pipe through the intake air is flowed around in the collecting room. This way, before the exhaust gas is introduced cooling of the same is possible in the suction pipe. The cooling must, however not through a separate duct system or one that is foreign to the combustion air Cooling medium can be reached. An additional design effort for cooling is therefore not incurred.
  • the requirements for the tightness of the exhaust duct are also lower in the intake manifold, since a small leak only leads to an earlier admixture of the exhaust gas leads to the intake air.
  • Screw connections and rivets are conceivable, for example Clamping, plug-in and snap connections, in addition, with a multi-layer Structure of the intake manifold a fixation of the exhaust pipe by mounting the Intake pipe shells are made. Bridges as spacers can conduct heat minimize with sufficient fixation. A further minimization is advantageous possible in that the holding means themselves allow low heat conduction. This can be done in particular by a small cross section of the holding means, that create a thermal bridge between the intake manifold wall and the exhaust pipe, or by choosing materials with low thermal conductivity, e.g. B. ceramics.
  • the supply openings of the exhaust pipe serve if this through the walls of the Suction channels must be guided.
  • a connection is therefore inevitable here between exhaust pipe and walls of the intake manifold, in particular the Suction channel, with the help of which the exhaust pipe can be fixed.
  • a ceramic fitting can also be used be at least the thermal insulation between the exhaust pipe and Suction pipe guaranteed.
  • the shaped piece made of ceramic can also be used for any Geometry of the discharge point, e.g. B. as a nozzle. The geometry of the discharge point can then with regard to an optimal distribution of the exhaust gas in the intake air be designed.
  • the feed openings become in the area of the suction openings the suction channels arranged, so the heat transfer can be further reduced.
  • the shells can e.g. B. consist of two deep-drawn metal parts, with the help of complicated geometric structures of the exhaust pipe let it be realized.
  • other functional components can be found in the shells be integrated.
  • flanges or spacers for fixing the exhaust pipe inside the intake manifold can be manufactured inexpensively.
  • the through the The channel structure formed by the shells can be supplemented by other components, the the base part can be assembled. So it is z. B. possible by connecting Pipes to complete the exhaust pipe.
  • the manufacture of the exhaust pipe from a metallic material ensures good heat conduction from the exhaust gas to the intake air in the intake manifold. Thereby optimal cooling of the exhaust gas can be achieved up to the inlet points, which makes the walls of the intake manifold less thermal in the area of the inlet points be charged.
  • metallic materials have a high temperature resistance, so that high recirculation rates of exhaust gas into the intake manifold are realized can be.
  • a heat-resistant plastic e.g. B. PPS can be used. Let it go favorable manufacturing and material costs are achieved.
  • the suction pipe itself is advantageously made of plastic. This is economical production possible. Especially with multi-shell technology the exhaust pipe without problems before final assembly of the intake manifold integrate. However, integration is also conceivable with plastic suction pipes, which are manufactured in melt core technology. In this case either Installation opening for the exhaust pipe are provided or the exhaust pipe in the Melting core are poured in, so that their position in the interior of the intake manifold is defined.
  • the invention can also be used in suction pipes made of metal, e.g. B. aluminum.
  • the geometry of the exhaust pipe in the intake manifold can advantageously be made in this way design that the path covered by the exhaust gas from the respective connection to the respective feed opening to the suction channels is always the same length. This synchronizes the dead times between opening the exhaust gas recirculation valve and introduction of the exhaust gas into the suction channels. Besides, will In this way, the exhaust gas is cooled to the same extent as the individual inlet points reached. The equalization of these effects leads to an optimal one Pollutant reduction through exhaust gas recirculation. Furthermore, a possible Reduction of engine torque counteracted by a short circuit, caused by the exhaust gas recirculation lines, could arise. The length of the Lines counteracts this as a choke.
  • FIG. 1 provides an insight into a lower shell 10 of an intake pipe. It is to recognize how the intake air according to the arrows from an inlet 11 on two collecting spaces 12 reaches suction openings 13 of suction channels 14, which lead to Outlets of a cylinder head flange 15, not shown.
  • An exhaust pipe 17a, b leads from a connection 16, which is shown in FIG. 1 in two variants is shown, to supply openings 18a, b, which the introduction of the exhaust gas in Area of the suction channels allowed.
  • the exhaust pipe 17a is by means of a snap connection 19 attached to walls 20 of the intake manifold. This creates a minimum distance a observed between wall 20 and exhaust pipe 17a, which leads to a thermal protection of the wall 20 contributes.
  • the exhaust pipe 17b is by means of Screws 21 fastened via tabs 22 in the intake manifold.
  • the structure of the exhaust pipe 17b can also be seen in FIG. 2. This is composed of two shells 23, which creates the cavity for conduction the exhaust gases are created.
  • the tab 22 for attaching the exhaust pipe is also integral part of one of the shells.
  • the feed opening 18b is in a feedthrough 24b inserted in the wall 20b of the corresponding suction channel 14. On at this point there is an admixture to the intake air, which leads to one of the outlets 25 flows in the cylinder head flange 15.
  • the intake manifold is manufactured and welded using multi-shell technology.
  • the suction channels 14 are welded into the lower shell 10.
  • an upper shell 27 with the lower shell 10 welded.
  • connection 16 is shown as a detail in section.
  • the connection exists from a pipe socket 28 which with the aid of a mounting flange 29 in a Implementation 24 is fixed.
  • a seal 30 in the form of an O-ring is in the Implementation housed.
  • the tube ends in a screw socket on one side 31, which allows the attachment of an exhaust pipe 32 and on the other Side in the exhaust pipe 17a, b (both versions are shown).
  • the pipe socket is in the area the implementation 24 designed as a bell-shaped hollow profile 33.
  • the feed openings 18b in the bushings 24b can also be designed in this way be that the heat conduction from the exhaust pipe to the wall 20b of the Suction channels 14 is prevented.
  • the feed is designed as a piece of pipe 34, which contains a bellows 35.
  • the exhaust pipe is on this piece of pipe 17b attached.
  • the pipe section in turn is inserted into the bushing 24b.
  • a shaped piece 36 made of ceramic can also be used. This is free in its design.
  • a nozzle 37 is formed at the end thereof, which leads to a targeted introduction of the exhaust gas. This nozzle is corresponding the curvature of the suction channel 14 aligned in the flow direction of the intake air.
  • FIG. 6 shows another example of a suction pipe, a part of the Collection space 12 is cut open, so that 2 variants of an exhaust pipe 17c and 17d become visible. This is through connection 16 and the snap connection 19 fixed.
  • the feed openings 18c of one variant open into the one described In the suction openings 13 of the suction channels 14.
  • the feed openings 18d are distributed stoichiometrically or regularly on the surface of the exhaust pipe 17d and thus lead to a uniform mixing of the intake air with recirculated Exhaust gas before it reaches the suction channels 14.
