Definitions

  • the invention relates to an intake system for an internal combustion engine according to the preamble of claim 1.
  • Intake systems often require a vacuum reservoir to be available with this If necessary, it is possible to drive stationary vacuum when actuating actuators or adjusting elements.
  • the vacuum reservoir is removed via a suitable valve vacuum and supplied via lines to the switching element.
  • the additional memory as independent component bolted to the existing intake system or - if it is in the suction system is integrated - sealed with a lid or a hood, to realize the vacuum reservoir.
  • the object of the invention is now to provide a compact, cost-effective intake system create, which is inexpensive to manufacture and with a vacuum reservoir available is, which ensures a simple but safe seal.
  • the intake system according to the invention for an internal combustion engine has an air collector, a suction pipe and a pressure accumulator, wherein the combustion air in the Air collector flows in and at least one suction pipe, which to the internal combustion engine can be connected, can be forwarded to the internal combustion engine.
  • the accumulator is here integrally connected to the intake system. This means that he does not have a separate, bolted or flanged housing or via an extra cover or extra hood on the intake system is realized, but that it is directly integrated into the intake system without the aid of further components. This has the advantage that no additional components are needed, which in another Work process must first be connected to the intake system and that no sealing measures, such as Sealing rings or O-rings, for sealing the pressure accumulator with the environment are needed. It is also clear that this is also results in a cost improvement of the prior art.
  • the invention have air collector, intake manifold and memory on a common division level.
  • This division divides the intake system in at least two housing part shells. From a production point of view it is better to divide the intake system in housing shells, so the respective To produce individual housing part shells inexpensive and easy.
  • the Housing part shells can consist of plastics or metals. Important is in this case, to select only corresponding material pairings, where either is possible, sealing the housing part shells via a positive connection method to connect with each other or where it is about making a non-positive Connection by means of e.g. a screw fastening is possible, a sealing connection manufacture.
  • the pressure accumulator on the air collector arranged.
  • the pressure accumulator integrally in the housing of the air collector existing chamber, which, however, compared to the volume of the air collector is sealed.
  • the pressure accumulator on the intake manifold arranged.
  • he can represent a kind of secondary strand of the suction tube, where he however, sealingly separated from the volume of the suction tube and the volume of the air collector is. Which of these two cases is used depends greatly on the spatial Conditions in the field of the internal combustion engine, so that from case to case a different Arrangement can be useful.
  • the intake system has a very low weight, it is simple and cheap to manufacture and there are no additional seals to separate the various Volumes of each other necessary.
  • a meaningful arrangement of the division level results from the connection by the vibration welding a insoluble, very good sealing connection of the housing shell parts to each other.
  • the intake system by two Housing part shells formed, wherein the pressure accumulator disposed adjacent to the air collector is and this has a first port, which corresponds with the air collector is connected and has at least a second terminal, which is connected corresponding to an actuating element.
  • the actuator can in this case represent a throttle valve, a shift shaft or the like.
  • About the first Connection, which connects the pressure accumulator with the air collector, is on the in the Air collector in operation of the engine prevailing negative pressure also a Negative pressure in the pressure accumulator caused.
  • the connection can also be via a valve take place, via the valve, a control of the building up in the pressure accumulator Vacuum can take place. This negative pressure is then used controlled to operate the actuator via the second connection.
  • the intake system 10 for an internal combustion engine shown in Figure 1 has a Air collector 11, more branched off from the air collector 11 suction tubes 12 and an am Air collector 11 arranged pressure accumulator 13.
  • the suction pipes 12 open into a Connecting flange 14, which serves the intake system 10 at a not shown here To fix internal combustion engine.
  • the suction tubes 12 are the respective Cylinders associated with the internal combustion engine.
  • the intake system 10 made of plastic, in particular a PA6 GF30, so a reinforced Polyamide, which can be easily vibration-welded.
  • a mounting flange 15 At the air collector 11 is a mounting flange 15, wherein this mounting flange 15 either to further Attaching the intake system 10 or serve to accommodate other functional components can.
  • the intake system 10 is here in an upper housing shell part 16 and a divided lower housing part shell 17, wherein between the two division plane 18th runs.
  • the two housing part shells 16, 17 are via a vibration welding process welded together in the region of the division plane 18.
  • a vacuum line 19 with a valve 20 disposed therein connects the pressure accumulator 13 to the air collector 11.
  • the vacuum line 19 on the one hand to a terminal 21 of the Air collector 11 and on the other hand connected to a terminal 22 of the pressure accumulator 13.
  • the regularly present in the air collector 11 negative pressure is so here used to generate and maintain a negative pressure in the pressure accumulator 13.
  • At the pressure accumulator 13 is still a connection 23 for a not shown here actuating element arranged, wherein the negative pressure in the pressure accumulator 13 is used, the To move actuator.
  • FIG. 2 shows a section through the air collector 11 and the pressure accumulator 13 lower portion of the air collector 11 is an inlet 24 through which the through a filter, which is not shown here, enters purified intake air.
  • a filter which is not shown here, enters purified intake air.
  • both volumes are integral with each other, they are separated by a Bridge 25 separated.
  • the web 25 is horizontal, ie transversely to the web direction divided by the division level 18.
