Definitions
- the invention relates to an air filter for an internal combustion engine according to the Features of the preamble of claim 1.
- the object of the invention is therefore to develop a device in which the Modulation of the intake noise is improved.
- the switchable openings in the air filter housing on simple way through an apertured and in the air filter housing implemented plate element, which together with in a housing wall of the Air filter arranged openings as a kind of shift register cooperates.
- the control of the plate member provided with the openings can be simple and manner via a vacuum box connected to a vacuum reservoir connected.
- the plate element lies in an advantageous manner as an underbody on the bottom wall of the Air filter housing on and is divided by two on the two long sides of the Plate element aligned rails, which provided at the openings Housing wall are fixed, guided.
- the in a housing wall of the air filter arranged openings monitored by flexible flap elements monitored by flexible flap elements.
- the flaps are closed; at high load and speed and corresponding air mass flow rate increases in the air filter housing prevailing negative pressure and the flexible flaps give the in the air filter housing provided openings free.
- the schematically illustrated air filter 10 is essentially a Air filter housing 12 is formed, which with an inlet 14 for the unfiltered raw air and an outlet 16 is provided for the clean air.
- a Filter element 18 is mounted, through which the interior of the air filter housing 12 in a lower room, hereinafter referred to as Rohluftraum 20 and an upper space in the hereinafter referred to as clean air space 22, is divided.
- the the raw air space 20 delimiting lower housing wall 24 is provided with rectangular openings 26.
- On the housing wall 24 is a displaceable plate member 28 which with Openings 30 is provided and their size and shape substantially with those in the Housing wall 24 provided openings 26 match.
- the Plate member 28 are on the two longitudinal sides of the plate member 28 at the Housing wall 24 fixed guide rails (not shown) provided.
- the plate member 28 is connected via a coupling rod 32 with a vacuum box 34th connected, which is supplied via a vacuum reservoir, wherein the coupling rod 32nd or the plate element 28 as a function of operating variables of the internal combustion engine, such as. Speed, load or temperature of the intake air is controlled.
- the control of the through the housing wall 24 and the plate member 28 formed Shift register is such that, as shown in Fig. 3, at idle or at low load and speed of the engine, the openings 26 in the Housing wall 24 are closed by the plate member 28, while at high Load and speed via the coupling rod 32, the plate member 28 in the in Fig. 4th is shown shifted arrow, so that the openings 26 and 30 lie one above the other and thus an airborne sound passage through the air filter housing 12 in the engine compartment is possible.
- the shape and size of the openings 26 and 30 can for the corresponding motor application can be adjusted.
- a second embodiment in the same components with the same Reference numerals are provided, which are provided in the lower housing wall 24 Openings 26 monitored by flexible flaps 32.
- the z. B. rubber o. ⁇ . Materials existing flaps 32 are on a longitudinal side of the rectangular openings 26th hinged and adapted in size to the dimensions of the openings 26 so that they in the closed position (see Fig. 5, 7), the openings 26 completely close.
- the flaps 32 close at idle or at low load and speed of the internal combustion engine due to the air filter housing 12th prevailing pressure conditions the openings 26, while at high load and Speed by the rising negative pressure in the air filter housing 12, the flaps 32nd automatically open inwards, so that a corresponding airborne sound passage is possible.
