Definitions
- the invention relates to an intake device for an internal combustion engine according to the preamble of the main claim.
- a suction device for a combustion engine is already known from DE-OS 40 41 786, in which a controllable shut-off device is provided to vary the passage opening through which the sucked-in air flows.
- the shut-off device is located in a transverse channel located between two suction channels and is opened or closed by control commands from control electronics. The control commands are dependent on the speed of the internal combustion engine and on the temperature of the outside air, which is determined with a temperature sensor.
- the invention is based on the object of developing an intake device for an internal combustion engine according to the preamble of the main claim that an adaptation is possible with simple means and without additional control devices. solution of the passage opening of the suction device to the operating states of the internal combustion engine is possible.
- the suction device according to the invention achieves the stated object with the features specified in the characterizing part of the main claim.
- the intake device according to the invention is particularly advantageous in that, in particular, the noise emission of the internal combustion engine is greatly reduced by a size of the passage opening for the intake air volume that is adapted to the speed in a simple manner.
- a certain size of the passage opening is optimal for each speed of the internal combustion engine, with a small diameter leading to the lowest possible noise emission at low speeds.
- variable, additional passage openings can also be made between the further inner tubes.
- the structural designs of the variable passage openings, as described below, can be used here in the same way.
- variable passage openings are realized in a simple manner by means of a passive flap mechanism which is formed in the intermediate space between the tubes which is fixed by web-like spacers.
- a passive flap mechanism which is formed in the intermediate space between the tubes which is fixed by web-like spacers.
- the flap mechanism here suffices to increase the intake pressure, for example when the speed of the internal combustion engine is increased.
- the flap mechanism according to one of claims 3 to 5 is designed as an elastic sealing lip, which is held on one side in each case and can be moved away from the other tube surface in the movable part in such a way that it fully or partially releases the additional passage opening .
- This elastic sealing lip is preferably made of a temperature-stable elastic material, e.g. B. elastomer, TPE or the like, so that the opening behavior is largely independent of temperature.
- the free, movable parts of the sealing lip are designed to be as long as possible in order to promote temperature independence.
- the elastic sealing lip is additionally slotted at the free end, so that the free parts are even more mobile.
- a possibly necessary contact pressure of the free part on the other tube can be easily produced by an annular spring.
- the at least one inner tube is somewhat longer than the respective outer tube and thus protrudes from the plane of the inlet opening. In this way, turbulence and a negative pressure in the additional passages are largely avoided, which adversely affect the suction behavior.
- Figure 1 is a sectional view through a first embodiment of a suction device with an inner and an outer tube and an elastic sealing lip;
- FIG. 2 shows a section through the suction device according to FIG. 1;
- FIG. 12 shows an embodiment of the suction device with different lengths of the inner tube at the outlet opening.
- FIG. 1 shows an intake device 1 for an internal combustion engine, not shown here, through which an air flow is drawn in according to arrow 2.
- the suction device 1 has an inner tube 3, an outer tube 4 and web-like spacers 5 between the tubes 3 and 4.
- the inner tube 3 is extended over the level of the inlet opening 6 by a predetermined amount.
- An elastic sealing lip 7 is held on the outer tube 4 at the inlet opening 6 and has a part 8 which is freely movable within limits.
- the sealing lip 7 is guided with the free part 8 obliquely to the rear in the suction direction, so that with a certain increase in the suction pressure the free part 8 of the sealing lip 7 moves away from the inner tube 3 and releases an additional passage opening for the air flow.
- FIG. 2 shows a section through the suction device according to FIG. 1, which in particular illustrates the position of the web-like spacers 5 between the tubes 3 and 4.
- FIG. 3 shows a first embodiment of the sealing lip 7 with the movable free part 8 in detail, a top view of the sealing lip 7 being shown in the right half of FIG.
- slots 9 are provided according to FIG. 4, which support a movement of the free legs of the sealing lip.
- the number and size of the slots 9 is selected as a function of the pressure conditions in the intake device or of the operating conditions of the internal combustion engine or the elasticity of the sealing lip 7.
- folds 10 are attached, which support the opening of the sealing lip 7 in a manner comparable to the slots 9 with reference to FIG.
- the exemplary embodiment according to FIG. 6 also has an annular spring 11 which effects a predetermined contact pressure of the sealing lip on the inner tube 3.
- annular spring 11 which effects a predetermined contact pressure of the sealing lip on the inner tube 3.
- FIG. 7 and FIG. 8 each show a further exemplary embodiment of the sealing lip 7 with a belly-like extension of the free part 8, which in part can have a certain rigidity in an area 12.
- the passage opening is also varied here by the arrangement of slots 9 (FIG. 7) or by folds 10 (FIG. 8).
- FIG. 9 shows an exemplary embodiment of an intake device 1 with a sealing lip 13 which is attached to the inner tube 3 and with its movable part lies against the outer tube 4. Further possible arrangements of the sealing lips 13 result from FIG. 10 (fastening in the region of the outlet opening 14 on the outer tube 4) and from FIG. 11 (fastening in the region of the outlet opening 14 on the inner tube 3).
- the constructive embodiments of the sealing lips 13 are adapted here to the respective application cases and can use the features described in FIGS. 3 to 8 with regard to the mobility.
- FIG. 12 shows a further design option for the inner tube 3, in which the inner tube 3 extends beyond the level of the outlet opening 14 in order to ensure the most favorable form in terms of flow technology when the air flow exits.
- a dashed line 15 also indicates a shortened shape of the inner tube 3, in which the inner tube ends in front of the outlet opening 14. The most favorable design in each case, particularly with regard to noise emission, depends in particular on the type of combustion engine which requires the intake air.
