Definitions

  • the invention relates to an arrangement of an air filter housing for an internal combustion engine in the engine compartment of a motor vehicle with the features of the preamble of patent claim 1.
  • the air filter consists of an Rohluftschale and a clean air bowl, which are releasably connected to each other, with a replaceable intake air filter between Rohluftschale and clean air bowl is arranged.
  • an air duct is arranged both on the clean air shell and on the Rohluftschale, enter through the air sucked by the internal combustion engine, or can escape.
  • the Rohluftschale is stationarily arranged on the body of the motor vehicle.
  • Object of the present invention is to integrate a generic air filter housing particularly space-saving in the engine compartment of a motor vehicle.
  • the air is sucked through the intake, generally called intake snorkel, above the coolant heat exchanger.
  • intake snorkel By formed by the body at least one air guide at the entrance to the air filter housing, the unfiltered air is deflected into the deep part of the air filter housing, where water and coarse particles are excreted and drained so that the filter is less polluted or moistened.
  • Moist intake air cools an air mass meter faster than dry, so that when the intake air is too moist, too large an intake air mass is determined and thus an incorrect amount of fuel is supplied to the internal combustion engine.
  • the pre-cleaned unfiltered air is fed to the air filter via an inflow opening with a catch collar. The cleaned after the air filter air then flows to an air flow measuring element, which is also integrated in the air filter module.
  • a further embodiment variant may be arranged according to claim 2 in the main flow before the air flow measuring element another flow element, whereby the air is rectified before the air flow measurement and a more accurate and precise measurement is possible.
  • the pressure loss is reduced by the flow guide to the air flow measuring element and the flow conditions of the air flow measuring element improves, whereby the characteristic of the air flow measuring element is improved, that is linearized.
  • the air quantity measuring element is a particularly robust hot film air mass sensor.
  • the Roh Kunststoffschale according to claim 4 has an opening through which the previously deposited pre-separated moisture and coarse dirt particles are excreted. This measure minimizes the danger of water hammer and extends the service life of the air filter.
  • an additional resonator can be arranged on the Roh Kunststoffschale and / or on the clean air bowl. By this measure unwanted noise is effectively damped.
  • the arrangement according to claim 6 allows a vibration control decoupling between air filter housing and internal combustion engine.
  • Fig. 1 shows a section through an inventive air filter housing 1.
  • the reference numerals of Fig. 1 apply to the same components for Fig. 2.
  • the air filter housing 1 consists of a Rohluftschale 3 and a clean air shell 4, between which a filter element 5, a commercially available air filter, is arranged.
  • the Roh Kunststoffschale 3 and the clean air tray 4 are detachably connected to each other at the peripheral edges 3 ', 4'. Between the peripheral edges 3 ', 4', a seal 12 is arranged.
  • the raw air shell 3 has a suction region 3 ", which is arranged on the body of the vehicle front 6.
  • the body forms in the present case, two air guide elements 6 'in the air intake.
  • the forward direction of travel of the motor vehicle is indicated by a double arrow.
  • FIG. 2 shows an installation situation for a cut, perspectively illustrated air filter housing 1 in the engine compartment of a motor vehicle.
  • the intake area 3 is arranged above a coolant heat exchanger 7.
  • the coolant heat exchanger 7 is largely covered by a cooling fan 11.
  • Geodetically above the coolant heat exchanger 7 is the intake area 3" of the air filter housing 1.
  • the air duct 4 In the perspective view in FIG the air duct 4 "recognizable, through which the clean air leaves the clean air bowl 4.
  • an air quantity measuring element 8 in the present case a hot-film air mass meter, is integrated into the air duct 4 ", downstream of the air duct 4", the intake air is conducted further in a pipe 10 in the direction of the internal combustion engine.
  • This is at least partially formed in a preferred embodiment as a corrugated pipe.
  • the air filter housing 1 arranged according to the invention has a resonator 9, which in the exemplary embodiment is arranged, for example, on the tube 10.
  • such resonators with which unwanted suction noise can be damped, can also be arranged on the untreated air shell 3 or on the clean air shell 4.
  • hot-wire air mass meters can also be used instead of the hot-film air mass meter.
