Definitions
- the invention relates to an air filter for an internal combustion engine according to the preamble of Such an air filter is known from DE-A-4 413 765.
- the inlet on the raw air side is usually in one Area arranged in the cold air can flow freely.
- the air inlet is located therefore normally behind the radiator grille of the vehicle or in the area of a fender. It has been shown that in particularly cold countries when driving through heavy snow or swirling snow are impaired, with which raw air is sucked in snow and this snow accumulates on the filter insert and may block the filter insert. This leads to a standstill of the engine.
- the invention is therefore based on the object of an air filter for an internal combustion engine to create, which ensures optimal snow separation and also the Cross-sectional area of the unfiltered air inlet is not or only slightly reduced.
- the advantage of the invention is that the sieve or the closed flap opens or closes depending on the raw air temperature.
- the movement sequence can be controlled, for example, using a wax thermostat. This means that the full cross-section is at a temperature above a certain value Raw air opening available.
- the internal combustion engine can achieve its maximum output unfold. Below the limit temperature, i.e. H. for example at a temperature of less than + 2 ° C the sieve or flap closes and prevents the raw air inlet thus the penetration of snow.
- the further raw air inlet is provided with a weight or spring loaded flap.
- the closing force is such dimensioned so that the flap only opens when there is a vacuum, which arises when the sieve is closed with snow or the flap due to the temperature of the raw air opening has closed.
- a further embodiment of the invention provides the further raw air inlet in the area a snow-free zone of the engine compartment. This can be behind the example Be an air cooler. There is also the possibility of this raw air inlet in the area of Exhaust manifold to arrange to suck in heated air.
- An air filter according to FIG. 1 has an air filter housing 10.
- a Air filter insert 11 arranged, for example, from a zigzag folded
- filter paper which is provided with a circumferential seal 12 and with this in a receptacle of the filter housing 10 is arranged.
- the filter insert 11 separates one Clean air room 13 from an unfiltered air room 14.
- the clean air room 13 is with a Provided connecting piece 15.
- the cleaned air flows in via this connecting piece 15 an internal combustion engine, not shown here.
- Located within the unfiltered air room 14 a first intake pipe 16 through which the cold air is fed to the filter device.
- the intake pipe 16 is at its open end facing the unfiltered air space with a Sieve basket 17 provided.
- This screen basket 17 has a screen with a corresponding Try to set a mesh size and serve to make snow or ice crystals effective intercept. If a large amount of snow is applied to this sieve basket, it settles this inevitably too. Air is therefore not sucked in through this suction pipe 16 more is possible. Suction is not possible even if the sieve swivel basket is pulled through a closed flap is executed.
- a further intake pipe 18 is therefore provided.
- the inlet of this intake pipe is on a location within the engine compartment of a vehicle that is free of snow. This can be, for example, in the area of the exhaust manifold or immediately behind the Radiator housing, with the arrangement behind the radiator housing it should be noted that this inlet surface is perpendicular to the radiator surface or the inlet mouth in Driving direction seen behind the engine.
- This additional intake pipe is connected to its inner opening facing the unfiltered air space a flap 19 closed.
- the flap 19 can be both spring-loaded and be weight-loaded. In the illustration shown here, this flap is weight-loaded Flap designed and rotatably mounted on the hinge 21. With a spring-loaded The spring is in the flap in the hinge 21.
- the temperature of the intake raw air rises above a value at which the Snow is unlikely to penetrate; H. for example 4 ° C
- Wax thermostat 22 opens Wax thermostat 22, the strainer 17 or the flap.
- the strainer basket 17 or the flap is attached to the suction pipe 16 with a hinge 23. This stands from this Limit temperature of the full passage cross section for the intake air or the raw air Available so that no loss of performance of the engine is to be feared.
- the wax thermostat 22 also closes the strainer basket 17 or the flap the suction pipe 16 and thus effectively prevents that Snow ingress.
- FIG. 2 shows a variant of an air filter with an anti-snow system.
- the intake tract 24 of an air filter for an internal combustion engine is shown.
- Intake tract is a screen 25 or flap, which is also from one Wax thermostat 22 can be operated.
- Below a limit temperature of for example, 2 ° C is the sieve 25 or the flap in the one shown here Position, d. H. if snow enters through the opening 26, it is removed from the screen disk 25 intercepted.
- an opening 18 ' i. H. the further intake pipe opened so that snow-free air can flow in.
- FIG 3 shows the different volume flows, which are particularly in one device adjust according to figure 1.
- the volume flow V1 ' is the raw air volume flow at one Flap, the volume flow V1 in a screen basket 17 via the intake pipe 16.
- the strainer or the flap closes the suction pipe 16 and thus reduces the maximum volume flow.
- the internal combustion engine is therefore provided with sufficient intake air in every operating state Available so that both at higher temperatures and at lower temperatures this can reach its maximum performance.
