Definitions

  • the invention relates to an air filter for internal combustion engines according to the preamble of the main claim.
  • an air filter is provided with an unfiltered air inlet and a further unfiltered air inlet which opens as a function of the negative pressure prevailing in the filter housing.
  • the further raw air inlet serves as an additional bypass to the raw air inlet in order to ensure a sufficient amount of air bypassing the filter insert even at full load.
  • unfiltered untreated air is supplied to the engine. This would inevitably lead to the motor being destroyed by the dirt particles.
  • a coordination with regard to the acoustic conditions is required. This takes place with a corresponding resonance volume, which is arranged in the area of the air filter. Opening an additional air inlet bypassing the air filter would result in the acoustic conditions deteriorating considerably and the engine producing an unusually high noise level.
  • the raw air side inlet In internal combustion engines for vehicles, the raw air side inlet is usually arranged in an area into which cold air can flow in unhindered.
  • the air inlet is therefore normally behind the radiator grille of the vehicle or in the area of a fender. It has been shown that snow is sucked in with the untreated air in particularly snowy countries during journeys which are impaired by heavy snowfall or snow swirls, and this snow accumulates on the filter insert and may clog the filter insert. This leads to a standstill of the engine.
  • the invention is therefore based on the object To create a device that is suitable to effectively prevent clogging of the air filter element with snow. This object is achieved on the basis of the preamble of the main claim by its characterizing features.
  • An essential advantage of the invention is the combination of a strainer basket with an additional raw air inlet, which opens when the strainer basket is clogged with snow and a certain negative pressure is established in the air filter housing.
  • the additional raw air inlet is arranged so that it sucks in snow-free air.
  • This snow-free air is normally in the area of the exhaust manifold of the engine or behind the radiator housing or at an appropriate location. If preheated intake air is supplied through this additional raw air inlet, then there is the possibility that the snow that is held back by the screen basket will defrost and the first raw air inlet will thus regain its function.
  • the spring when using a spring-loaded flap, is a spring coil which has legs at its ends, while one of the legs lies against the fixed housing, the other leg exerts a centrally acting force on the flap via a web out.
  • a spring has the advantage that assembly is very simple. This spring is simply snapped into its holder. Hooking in or additional fastening is not necessary.
  • the flap can be attached in a simple manner.
  • the flap has a shaft which is inserted into a so-called offset bearing on one side and engages in an open bearing on the opposite side. No further fastening elements are required here either.
  • the entire flap system can be integrated into a raw air inlet or part of one Be raw air inlets.
  • no additional assembly aids are required with suitable latching devices or snap connections.
  • the screen basket is provided with a plastic ring and is also latched in the raw air inlet.
  • the flap which closes the further raw air inlet can be both spring-loaded and weight-loaded. It is essential to match the weight or the spring to a maximum negative pressure in the air filter housing which must not be undercut.
  • an air filter insert 11 is arranged inside an air filter housing 10, which consists, for example, of a filter paper folded in a zigzag shape, which is provided with a circumferential seal 12 and is arranged with this in a receptacle of the filter housing 10.
  • the filter insert 11 separates a clean air space 13 from an unfiltered air space 14.
  • the clean air space 13 is provided with a connecting piece 15.
  • the cleaned air flows via this connecting piece 15 to an internal combustion engine, not shown here.
  • the intake pipe 16 is provided with a strainer basket 17 at its open end facing the unfiltered air space.
  • This sieve basket 17 has a sieve with a mesh size of 0.2 mm - 0.3 mm and serves to effectively intercept snow or ice crystals. If this screen basket is loaded with a large amount of snow, it will inevitably become clogged. A suction of air is therefore no longer possible via this suction pipe 16.
  • a further intake pipe 18 is therefore provided.
  • the inlet of this intake pipe is located at 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 or at another snow-free location, with the arrangement behind the radiator housing to ensure that the inlet surface is at right angles to the radiator surface.
  • This other intake pipe is on its inner opening facing the unfiltered air space is closed with a flap 19.
  • the flap 19 can be both spring-loaded and weight-loaded or via appropriate electronics. In the illustration shown here, this flap is provided with a weight 20 and rotatably mounted on the hinge 21. In the case of a spring-loaded flap, the spring is located in the hinge 21.
  • the suction effect of the internal combustion engine creates a negative pressure in the intake pipe on the clean air side, which continues on the unfiltered air side or the unfiltered air space 14.
  • This low pressure causes the flap 19 to open, so that combustion air can now flow in via the further intake pipe 18. If this combustion air is warmed, this heating causes the snow accumulated in the sieve basket to be defrosted and thus the suction pipe 16 to become free, so that fresh air can then be sucked in again via the suction pipe 16.
  • the vacuum in the unfiltered air space thus drops and the flap 19 closes again.
  • the weight 20 or the spring force in a spring-loaded flap is chosen so that the negative pressure required to open the flap does not rise above a certain permissible value.
  • FIG. 2 shows a variant of an intake system.
  • an air filter housing 10 is shown in a top view.
  • the air filter housing is provided with a connecting piece 15 for the clean air and with a connecting pipe 22 for the raw air.
  • the raw air inlet 22 branches and leads to an air inlet 16 which is provided with a screen basket 17.
  • An air inlet 18 is also provided. This is arranged immediately behind a vehicle radiator 23. The air inlet 18 is closed with a spring-loaded flap 24 in the normal case. If snow or ice crystals clog the sieve basket 17, it then opens in the filter housing resulting vacuum, the flap 24, so that warm air is sucked in through the dirty air inlet 18.
  • FIG. 3 shows a flap 24 which closes an intake pipe (not shown here).
  • the flap 24 is attached to a housing via a shaft 25.
  • the shaft 25 is inserted into a so-called offset bearing 26 on the left-hand side and snapped into an open bearing 27 from the top on the right-hand side.
  • the offset bearing 26, the lower half-shell of which is formed on the right-hand side and the upper half-shell on the left-hand side, has the advantage that the shaft can be inserted outside the axial alignment.
  • the flap 24 consists of a plastic injection molded part and has a rib 35 which is arranged in the center.
  • the leg 29 of the spring 28 abuts the rib 35 and exerts a closing force.
  • the further leg of the spring 28 is supported on a holding part 30 fixed to the housing.
  • the spring is inserted between the two bearing legs during assembly and is held in its installed position by the lugs 31 and 32.
  • the entire flap 33 can be assembled as a complete system and can be adapted to a raw air inlet, not shown here.
  • the spring is arranged in the vicinity of the offset bearing 26. A larger lifting arm to the bearing 27 is thus achieved, so that small transverse forces are exerted on the bearing 27 due to the spring action.
  • the location for the spring within the shaft 25 is designed in the form of an open U. This can be stiffened with ribs or, as shown in FIG. 4, closed with a pocket bottom 34. This ensures the stability of the shaft 25 and defines the installation space of the spring.
