Definitions
- the invention relates to an air filter for an internal combustion engine according to the features of the preambles of claims 1 and 4.
- JP-10339225 an air filter housing for an internal combustion engine is shown in which are introduced for sound modulation in the side wall openings, which are monitored or controlled by flap elements.
- the object of the invention is to develop a device for an air filter through which the intake noise over the load and speed range of the internal combustion engine can be effectively modulated in a simple manner.
- the switchable openings in the air filter housing in a simple manner by a perforated and guided in the air filter housing plate element implemented, which cooperates with the arranged in a housing wall of the air filter openings as a kind of shift register.
- an airborne sound passage through the air filter housing in the engine compartment so that the sound pattern in the passenger compartment of the motor vehicle can be improved in the desired sense, depending on the operating condition of the internal combustion engine.
- these openings are designed to be closed. At high load and speed then these airborne sound passages can be opened to ensure an attractive interior sound.
- pulsations of the intake air are reduced by the additional openings in the air filter and the air filter housing less excited to vibrate.
- the control of the plate member provided with the openings can be done in a simple manner via a vacuum box which is connected to a vacuum reservoir.
- the plate member is advantageously as a bottom on the bottom wall of the air filter housing and is guided by two aligned on the two longitudinal sides of the plate member rails which are fixed to the housing wall provided with the openings.
- the openings arranged in a housing wall of the air filter are monitored by flexible flap elements.
- the control of the flaps is effected by the pressure conditions present in the air filter. At low load and speed the flaps are closed; At high load and speed and corresponding air mass flow rate, the negative pressure prevailing in the air filter housing increases and the flexible flaps release the openings provided in the air filter housing.
- the schematically illustrated air filter 10 is essentially formed by an air filter housing 12, which is provided with an inlet 14 for the unfiltered raw air and an outlet 16 for the clean air.
- a filter element 18 is mounted, through which the interior of the air filter housing 12 in a lower space, hereinafter referred to as raw air space 20 and an upper space, hereinafter referred to as clean air space 22 is divided.
- the raw air space 20 bounding the lower housing wall 24 is provided with rectangular openings 26.
- On the housing wall 24 is a displaceable plate member 28 which is provided with openings 30 and whose size and shape substantially coincide with the openings provided in the housing wall 24 openings 26.
- To lead the Plate member 28 are provided on the two longitudinal sides of the plate member 28 on the housing wall 24 fixed guide rails (not shown).
- the plate member 28 is connected via a coupling rod 32 with a vacuum box 34 which is supplied via a vacuum reservoir, wherein the coupling rod 32 and the plate member 28 depending on operating variables of the internal combustion engine, such as. Speed, load or temperature of the intake air is controlled.
- the control of the shift register formed by the housing wall 24 and the plate member 28 is such that, as shown in Fig. 3, at idle or at low load and speed of the internal combustion engine, the openings 26 in the housing wall 24 are closed by the plate member 28, while At high load and speed over the coupling rod 32, the plate member 28 is moved in the direction of arrow shown in Fig. 4, so that the openings 26 and 30 are superimposed and thus an airborne sound passage through the air filter housing 12 into the engine compartment is possible.
- the shape and size of the openings 26 and 30 can be adapted for the corresponding motor application.
- the openings 26 provided in the lower housing wall 24 are monitored by flexible flaps 32.
- the z. Materials made of rubber o. ⁇ .
- Existing flaps 32 are articulated on a longitudinal side of the rectangular openings 26 and adapted in size to the size of the openings 26 so that they in the closed position (see Fig. 5, 7), the openings 26th completely close.
- the flaps 32 close at idle or at low load and speed of the internal combustion engine due to the prevailing pressure in the air filter housing 12, the openings 26, while at high load and speed by the rising negative pressure in the air filter housing 12, the flaps 32 open automatically inward, so that a corresponding airborne sound passage is possible.
