Definitions
- the invention relates to an intake system for an internal combustion engine, in particular an internal combustion engine driving a vehicle, having a resonator, according to the features of the preamble of claim 1.
- DE 42 15 416 A1 a suction system is known in which between one Air filter and an injector of the internal combustion engine an air supply line is arranged.
- the internal combustion engine is via this air supply line or their injection device fresh air supplied, the fresh air supplied is metered by means of a throttle valve.
- the Fresh air is drawn in by the internal combustion engine, causing vibrations the air column in the air supply line, the uncomfortable and annoying Cause suction noise. Therefore, DE 42 15 416 A1 proposes Air supply line a resonator, which is designed here as a Helmholtz resonator is to be attached. These are both on the Helmholtz resonator a flange is also arranged on the air supply line, via which the two Components are interconnected. This can be the annoying Eliminate suction noise as far as possible, whereas this is described in DE 42 15 416 A1 described suction system has the disadvantage that it with respect to the Variety of parts and the assembly effort is in need of improvement.
- the invention is therefore based on the object that described above To improve the suction system so that the assembly effort is reduced becomes. Another aspect of the task is the fact that for the Suction system gives a pleasing appearance, which makes the suction system lighter in the available space in the outside area of the internal combustion engine is to be accommodated.
- the resonator is designed as a resonator module, wherein the resonator module from a resonator housing and a resonator housing cover exists and the resonator housing and the resonator housing cover be inextricably linked.
- the resonator module there is only a single part left in the suction system assemble.
- the air filter above which fresh air for combustion in the internal combustion engine is sucked in, attached and a connection on the output side to the injector of the internal combustion engine.
- the resonator module and the air filter respectively whose air filter housing form a single component.
- the resonator housing and the resonator housing cover be inextricably linked, as a resonator module is available, which is constructive to the respective type of Internal combustion engine in which it is to be used can and thus reduces the variety of parts during assembly.
- the resonator module can be prefabricated and as a finished Component for example in the production of the internal combustion engine or also is available when installing the internal combustion engine in a vehicle. Furthermore, leaks are effectively avoided, so that sealants can be omitted.
- suction instructions are provided in the resonator housing provided, which is at least partially formed by the resonator housing is. This further increases the integration of components of the resonator module, so that automatically with the installation of the resonator module not only the resonator is available in itself, but also the connection between the air filter and the injector of the internal combustion engine. This means that the available space is also compact Well used resonator module.
- the suction line cover also becomes unsolvable connected to the resonator housing.
- the suction line cover also becomes unsolvable connected to the resonator housing.
- the suction line cover Just like the inseparable connection of the resonator housing cover with the resonator housing has permanent connection of the suction line cover to the resonator housing the advantage that there is inevitably a tight connection between those involved Components is made, so that leaks and associated therewith Shifts in the resonance frequency can be effectively prevented.
- an inseparable connection (such as gluing) easier and safer to establish than, for example, a connection via Flanges with a gasket in between, the flanges together be screwed.
- the assembly effort is not only reduced, but also automated can what especially in a series production of resonator modules is particularly effective and inexpensive.
- the suction line cover has an air guiding section on the suction line with the volume of the resonator housing connects. This means that not only the suction line is inside the resonator housing, but also the resonator, which makes the handling of the resonator module is further improved during installation.
- the suction line cover with the air guide section formed as a component which also reduces the variety of components becomes. This is again in the manufacture of the resonator module including all its plastic components of particular advantage, where this will be discussed in the following.
- the suction system is characterized by its Manufactured from plastic, in particular a heat-resistant plastic.
- a heat-resistant plastic that also with the appropriate heat in the Engine compartment retains its shape is therefore necessary, because when operating the Internal combustion engine, particularly in an engine compartment of a vehicle is housed, high temperatures prevail that do not cause deformation of the resonator module.
- Heat-resistant is understood to mean that the resonator module made of plastic also at low temperatures (which prevail in winter, for example) is exposed to after commissioning the internal combustion engine, the temperatures in the engine compartment increase sharply. So these temperature fluctuations must not become one Deform the geometry of the resonator module.
- the manufacture of the resonator module is Suction system characterized by a shape and at least two cores Manufacture of the resonator housing by casting or injection molding Plastic.
- the shape forms the outer contours of the resonator housing, whereby in this form two cores are inserted, one core being the resonator volume (thus the inner contours of the resonator housing) and the open section of the suction line, with the manufacture of the resonator housing is produced simultaneously, forms and the second core the inner contours a tubular piece of the suction line within the resonator housing forms, the outer contours of the tubular piece from the first Core are formed.
- the resonator housing is open simple way using a shape and at least two cores in the Casting or injection molding process can be made of plastic and without problems to core and take out of shape.
- the suction line cover is also covered made a mold and a core, which makes the suction line cover in one work step can be produced as a one-piece component, that at the same time takes on the task of covering the open area of the suction line and at the same time the connection between the suction line and the resonator volume and the resonator housing.
- means for changing the resonator volume are in particular a flap or a slide, and an actuator for setting the means for changing the resonator volume in the resonator module integrated.
- the actuator can, for example, depending on a Parameters of the internal combustion engine, in particular the speed, of one Control direction can be controlled.
- the actuator for setting the means for change of the resonator volume is either inside the resonator housing for example attached to the suction line cover or also arranged outside the resonator module.
- An arrangement within the The advantage of resonator modules is that there are no bushings through the walls of the resonator module are required, which also causes sealing problems here be effectively avoided.
- a resonator module 1 is a three-dimensional view in FIG Suction system of an internal combustion engine shown.
- the resonator module 1 exists from a resonator housing 2, at one end of the resonator housing 2, a flange 3 is provided with which the resonator module is connected to a Air filter for fresh air intake is connected.
- a further flange 4 is provided, the Flange 4 via a pipe piece 5, in particular tubular, with another Flange 6 is attached to the resonator housing 2.
- the arrangement and the alignment of the flanges 3, 4 and 6 is only exemplary and is shown in Dependence of the installation space and the position of the air filter, which on the Flange 3 is connected, and depending on the position of the injector the internal combustion engine, which is connected to the flange 4, chosen.
- the resonator housing 2 also has fastening means which are illustrated by way of example 7 with which the resonator module 1 are fixed in place can.
- the resonator housing 2 is not yet completely closed, but rather has Connecting edges 8, more precisely a completely circumferential connecting edge 8, on with the connecting edge 8 the contours of a resonator housing cover or its side parts correspond.
- a suction line 9 is arranged inside the resonator housing 2, wherein this suction line 9 at least partially simultaneously with the manufacture of the resonator housing 2 is ordered.
- This suction line 9 and the resonator housing 2 thus form a one-piece component.
- the suction line 9 is on their the entire extent is not yet closed, but in the area of a connecting edge 10 or of connecting surfaces 11 and 12 still open. Since the suction line 9 is approximately tubular, it instructs one end, especially at the end, which is in the direction of the flange 3 is aligned, a tubular piece 13, the tubular The length of piece 13 is straight, i.e. approximately as a cylindrical line, is trained.
- This shown in Figure 1, or correspondingly similar configurations have the advantage that the resonator housing 2 by means of a shape and at least two cores can be produced.
- the shape describes the outer contours of the resonator housing 2, while one core is the inner volume of the resonator housing 2, the open part of the suction line 9, the connecting edge 10 and the connecting surfaces 11 and 12 and the surface of the tubular piece 13 describes.
- the second core forms the inner core of the tubular piece 13, so that after casting or Injection molding a coring and a removal of the finished resonator housing 2 is made possible from the mold.
- FIG. 2 shows a suction line cover 14 which corresponds to that in FIG. 1 shown open area of the suction line 9 covers.
- the suction line cover 14 consists of a part-circular cover 15 covering the open area covers the suction line 9 in the sense of an arcuate pipeline.
- the suction line cover 14 has connecting surfaces 16 on, which correspond to the connecting surfaces 11 and 12 of the resonator housing 2.
- the suction line cover 14 also takes on the task a connection from the now more closed suction line 9 to the volume to produce the resonator housing 2.
- an air guide section 18 as a separate component can be placed, the air guide section 18 being particularly advantageous Production of the suction line cover 14 is already formed or with this is inextricably linked.
- the air guide section 18 has an opening 19 on, which is directed in the direction of the volume of the resonator housing 2.
- a further opening 20, which is only hinted at here, provides a connection between the air guide section 18 and the suction line 9, in particular in the vicinity of the Flange 6, forth.
- the resonator housing 2 is shown in FIG Resonator housing cover 21 on the resonator housing 2 according to the Connection edges 8 placed and also by gluing, welding or the like is sealingly connected to the resonator housing 2.
- the ready-to-install resonator module 1 is available and can be Flanges 3 and 4 with the air filter and the injector of the internal combustion engine get connected.
