Definitions

  • the invention relates to an intake manifold for the intake air of internal combustion engines, which is a relief point in the intake manifold for coming from the cylinder Has pressure waves, according to the preamble of claim 1.
  • Such relief points for suction pipes are generally known.
  • the Relief points are used for the targeted reduction of pressure waves so-called back-fire contained energy.
  • the back-fires are flashbacks, the starting from the cylinder-side inlets of the intake manifold in the Extend the air ducts of the intake manifold.
  • the risk of occurrence This phenomenon exists above all when the internal combustion engine with a large overlap of valve timing works.
  • the back fire exists then from an already ignited portion of the fuel-air mixture in the cylinder. Above all when using plastic suction pipes the back fire can destroy the intake manifold structure. This will the function of the internal combustion engine seriously endangered because of the destroyed Intake pipe from the internal combustion engine unfiltered secondary air are sucked in can. In this case, neither can the supply to the internal combustion engine Intake air of the required degree of purity and compliance with limit values be guaranteed with regard to the pollutant emission of the internal combustion engine.
  • the object of the invention is to relieve pressure waves in an intake manifold create the function of maintaining the emergency running properties of the Internal combustion engine reliably and effectively guaranteed. This task will solved by the features of claim 1.
  • the intake manifold according to the invention which in a known manner the passage of the Intake air allows, has a burst geometry as a relief point, which in a wall section of the suction pipe is housed.
  • This burst geometry flows into a deflagration volume.
  • the burst geometry becomes the deflagration volume to dissipate the energy of the Blast wave used.
  • the overall structure of the intake manifold therefore remains unchanged exist, the deflagration volume being closed off to the outside Represents space, so that the overall system even after breaking open the Bursting geometry still represents a closed system. That way they are Emergency running properties of the internal combustion engine are given, even if the damage occurs is noticeable by a changed charge change of the internal combustion engine makes. In any case, the vehicle can get out with the damaged intake manifold to move to the next workshop.
  • the burst geometry can be an integral part of the walls of the intake manifold or be connected to it as a separate part.
  • the suction pipe wall is glued.
  • the adhesive bond is then as that Predetermined breaking point, so that a back-fire leads to the cover from the Opening is triggered and thrown into the deflagration volume.
  • the deflagration volume can be placed anywhere on the intake manifold become. However, places that are close to the place of origin of the Back-fires lie.
  • the burst geometry can then go into the wall of the suction channels the cylinders are installed.
  • Another possibility is the arrangement of the Deflagration volume in the collecting area compared to the exits from the Collection space in the suction channels of the suction pipe. A spreading back fire is then directed along the comparatively stable suction channels and meets in Collecting space on the burst geometry, which is destroyed as a result.
  • the wall section is formed by a glued-in lid, it is advantageous to make this and the associated installation opening conical, so that the lid can only be inserted from the side of the deflagration volume. This causes the lid to protrude into the deflagration volume clearly defined. If the lid is circular, it is additional ensures that it does not explode after being blown out Deflagration volume can get into the intake manifold, where it becomes a Airflow could be impaired.
  • Another embodiment of the invention results when the wall section through a targeted weakening is formed in relation to its wall environment. He can then be made in one piece with the intake manifold, for example as a cast part. The weakening of the wall then leads to failure of the suction pipe exactly this point in the case of a back-fires.
  • the weakening of the Wall section formed by a furrow that runs along a tear edge Bursting geometry runs. If the furrow is joined together in a ring, it forms This creates a lid-like structure that blows out through the back fire can be.
  • Embodiment of the invention provides that the furrow on the Suction pipe inside the remote side of the wall, so on the side of the Deflagration volume.
  • the inner contour of the suction pipe can be provided by the Burst geometry remain completely unaffected, so that its flow properties are the same as for a suction pipe without a burst geometry.
  • the wall section can expediently ensure a burst geometry reinforced connection area to the surrounding wall of the intake manifold exhibit.
  • the reinforced area remains, whereby it can be designed like a hinge.
  • the wall section remains on then hang this hinge and can not get into the intake manifold, where he the Intake manifold flow would negatively affect.
  • the reinforced area can be separated by a Furrow geometry change can be generated. This must be done that in the reinforced area the wall thickness is greater than in the area Furrow.
  • a particularly favorable geometry of the wall section results if the Furrow gets an oval shape.
  • the desired furrow failure in the event of a At the very least, this geometry can be predicted very well. This will make the Functional reliability of the burst geometry is positively influenced.
  • a possible one Stress peaks occur when loading a square lid avoided.
  • these advantages can also be achieved with a achieve circular wall section, which in this sense is a special case of the oval Wall section should be understood.
  • the wall section can include be provided with a crease. This runs through the area of the Wall section, whereby this can be weakened in a targeted manner.
  • the furrow preferably runs along a straight line and from an edge of the wall section on the other hand. The effect of such a crease can be achieved with a hinge compare, causing a detachment of the wall section in the event of a burst is supported.
  • several articulated furrows can also be provided, that can also cross. The burst behavior of the wall section can be influence in this way optimally, whereby an unproblematic degradation of the Pressure wave into the deflagration volume is guaranteed.
  • the deflagration volume can occur simultaneously perform another task. For example, this can be achieved that the deflagration volume has openings towards the interior of the intake manifold. On in this way, the empty space can correspond to the interior of the intake manifold the intake noise can be dampened in a targeted manner. It is here in particular to the Use of the deflagration volume intended as a resonance room. Such Resonance rooms are common due to acoustic requirements for the intake manifold available anyway. In such cases, the use of this cavity means Deflagration volume no additional manufacturing effort. Also will no additional volume is required in the installation space of the internal combustion engine.
  • deflagration volume As Vacuum accumulator, this for the actuation of others Engine components are needed.
  • the one in the deflagration volume At the same time, negative pressure increases the effect of the burst geometry in the event of failure, because in relation to the pressure in the intake manifold, a larger proportion of the back-fire pressure wave can be intercepted.
  • FIG. 1 shows the structure of a suction pipe with deflagration volumes.
  • the air enters an collecting space 11 through an inlet 10, from where it passes through Suction channels 12 is directed to the cylinder-side outlets 13 so as not to there to pass illustrated intake valves.
  • the flow direction of the air in normal operation the internal combustion engine is indicated by a solid arrow.
  • the direction of the back-fire is indicated by dashed arrows.
  • Deflagration volume 14 is arranged adjacent to the suction channels 12.
  • a burst geometry 15 housed in the common wall between deflagration volume 14 and suction channel 12 .
  • This consists of a wall section 16 which is surrounded by a furrow 17 (see also Figure 2).
  • the furrow tapers to one Connection area 18, so that here a greater wall thickness than in the area of Furrow is present. If the burst geometry fails, the furrow tears open, wherein a tear edge 19 forms in the area thereof, and the wall section folds along the connection area 18 into the deflagration volume 14.
  • the pressure wave of the back-fire can also enter this cavity expand, leaving the rest of the intake manifold undamaged.
  • the deflagration volume 14 is also used as a vacuum reservoir. For this is attached to the wall of a hose connector 20 through which the Vacuum accumulator with a hose system, not shown, for actuation is connected to pressure-controlled switching components of the engine.
  • Another deflagration volume 14a is adjacent to the collecting space 11 opposite of inputs 21 of the suction channels 12 housed.
  • a partition 22 between collecting space 11 and deflagration volume 14a is conical Provided cover 23, which forms the wall section 16 of the burst geometry 15.
  • This cover is an adhesive joint 24 in the associated installation opening used, the pressure wave of a back-fires to fail this Adhesive connection leads. As a result, the lid is inserted into the deflagration volume 14a hurled.
  • the lid is also provided with openings 25 so that Deflagration volume 14 a simultaneously as a resonance chamber in normal operation Internal combustion engine works.
  • the openings form the necks of one Helmholz resonators.
  • the wall sections 16 are fitted into the intake manifold walls such that a Air routing geometry 26, which is formed by the inner walls of the suction pipe, in normal operation of the internal combustion engine not due to flow obstacles being affected. This is achieved in that the furrow 17 and the Connection area 18 on the side of the deflagration volume 14 into the wall are introduced and the lid 23 is inserted into the conical installation opening is that the wall parts run evenly along the adhesive joint 24.
  • FIG. 3 shows an example of the wall section 16 with an oval shape. This is surrounded by the furrow 17, which has a constant V-shaped cross section. Along the long diameter of the oval runs a crease 27, which the Furrow 17 touched on opposite sides.
  • the mode of action of the crease 27 can be seen in FIG. 4. in case of a The wall section bursts out of the wall in the direction of the arrows indicated blown out.
  • the crease 27 acts like a hinge which is closed folding the wall section leads.
  • the wall section 16 at least partially separated in the furrow 17 from the rest of the suction pipe so that the tear edge 19 results, the one shown in broken lines Condition is indicated.
  • the pressure wave can pass through the opening be dismantled.
