  • the invention relates to an air intake filter for an internal combustion engine according to the preamble of claim 1.
  • Air intake filter are used in the intake tract of internal combustion engines to subject the sucked outside air before the introduction into the cylinder of the internal combustion engine of a filtration.
  • Air intake filters comprise a filter element accommodated in a filter housing, through which the air to be filtered flows.
  • the filter housing has a suction port, which is connected to the intake passage of the intake.
  • the invention is based on the object of designing an air intake filter for internal combustion engines with simple design measures in such a way that both in heavy rain and in wintry conditions reduced performance or even destruction of the engine.
  • the air intake filter according to the invention is used in the intake tract of internal combustion engines for the filtration of the intake ambient air and comprises in a filter housing, a filter element to which air can be supplied via a main suction, which is introduced into the filter housing.
  • a filter element to which air can be supplied via a main suction, which is introduced into the filter housing.
  • an additional suction opening is introduced into the filter housing, which, like the main suction opening, communicates with the raw side of the filter element and is arranged at a distance from the main suction opening.
  • the filter housing has at least two suction openings, via which air is to be supplied to the filter element.
  • the air supply is at least for the most part via the main intake; the auxiliary suction port is either disabled, e.g. Blocked by a check valve, or it passes due to a suitably smaller cross-section of the additional suction only a smaller partial air flow through this opening to the filter element.
  • the air supply via the Rajansaugötechnisch not only works when water enters the intake tract of the internal combustion engine, but also in other difficult weather conditions, e.g. in the event of snow and ice entering the intake tract and clogging the main intake opening.
  • the additional opening is preferably located at a significant distance from the main intake to the filter housing.
  • the Rajansaugö réelle is based on the regular installation position of the air intake filter in the engine compartment of the vehicle positioned at a higher point than the main intake, so that also the risk is reduced that water can penetrate into the additional suction.
  • the filter housing of the air intake filter is expediently composed of a base housing and a lid or cap to be mounted thereon.
  • the additional suction is preferably in the hood. Also, the main suction can be introduced into the hood, but with distance to the additional suction.
  • the additional suction opening is preferably arranged on the raw air side.
  • the insert serves, for example, for flow guidance;
  • the insert part is designed as a flow guide part.
  • the insert part assumes a prefilter function by, for example, a sieve or another filter element is inserted into the insert part.
  • a sieve advantageously made of plastic, such as polyamide (PA).
  • a sieve made of plastic fabric is suitable, for example, PA.
  • a sieve or plastic fabric has a prefilter function, but it is mainly used to reduce hot air intake from the engine compartment.
  • an outflow opening is introduced into the filter housing in the region of the raw air side of the filter element, can be derived from the filter housing via the penetrated water, which has been introduced via the intake duct.
  • an insert may be used, which is optionally provided with a filter element, such as a sieve to complicate the air supply via the discharge opening and in the event that air is still sucked through the outflow opening, a prefilter function takes over.
  • the outflow opening is expediently located at a low point in the filter housing, based on the regular installation position of the air intake filter in the engine compartment of the vehicle.
  • FIG. 3 is a view of the inside of a hood of the air intake filter
  • Fig. 4 shows the air intake filter in section, with an insert in one
  • FIG. 10 shows the filter housing according to FIG. 9 in a further perspective view, FIG.
  • FIG. 11 shows a complete air intake filter with a filter housing according to the figures 9 and 10,
  • the air intake filter 1 comprises a filter housing 2, which is constructed in two parts with a base housing 3 and a hood 4, and a filter element 5 accommodated in the main housing 3, through which the combustion air to be filtered flows.
  • the aufsonde on the base housing 3 hood 4 forms a cover and is provided with a main suction port 6 through which the unpurified combustion air is passed into the interior of the filter housing 2 and led to the raw side of the filter element 5. After flowing through the filter element 5, the purified air is discharged via a discharge port 7 in the direction of the internal combustion engine.
  • an additional intake opening 8 is introduced into the hood 4 of the filter housing 2 at a lateral distance from the main intake opening 6.
  • an insert 9 is used, which has an air guide and filter function.
  • the main suction opening 6 is located with the outflow in a first plane which is perpendicular to a second plane is located in which at least approximately the wall outside of the hood 4 with the main suction port 6 and the additional suction 8 is located.
  • the additional suction opening 8 has a significant distance both to the main suction opening 6 and to the discharge nozzle 7. In the installation position, the additional suction opening 8 is located at a high position of the filter housing, so that it is ensured that penetrating water or snow or ice, which can lead to a blockage of the main suction 6, not enforce the additional suction 8.
  • the main intake port 6 either opens directly to the engine compartment of the vehicle in which the air intake filter 1 is installed, or is supplied with combustion air via an intake passage in the engine compartment, in which case the auxiliary intake port 8 is positioned outside this intake passage, so that air out the engine compartment via the additional intake 8 can flow.
  • the insert part 9 is preferably inserted from the inside into the additional intake 8 in the hood 4 , As can be seen from FIGS. 3 to 6, the insert part 9 is of annular design and has a central recess through which additional air enters the interior of the filter housing to the raw side of the filter element. In the central recess, a support member 11 is inserted into the insert part 9. The support part 11 is connected to a nem central support ring and radially extending struts provided. It has a prefilter function and prevents coarse dirt or snow and ice from reaching the interior of the air intake filter via the additional intake opening 8.
