Definitions

  • the invention relates to an air filter for an internal combustion engine according to the preamble of claim 1.
  • the engine compartments of modern passenger cars have to accommodate a number of auxiliary units, the accommodation of which causes considerable problems due to the limited space.
  • the intake system of the internal combustion engine with the air filter and the air mass meter has a considerable space requirement, since the former must have a relatively large volume for accommodating the required filter area and for damping the intake noise, and the latter, as a hot-wire or hot-film air mass meter, a measuring tube with a relatively large size Has diameter in which the hot wire or the hot film is arranged.
  • the invention has for its object to reduce the space required for the intake system of a vehicle internal combustion engine and in particular for the air filter and the air mass meter.
  • the air mass meter is integrated into the air filter, in that the measuring tube is arranged essentially parallel to the plate-shaped filter element within the air filter housing.
  • the proposal according to the invention accommodates the air mass meter without any significant additional space requirement and without a significant reduction in the active filter area.
  • one end of the measuring tube extends outwards from the air filter housing through a sealing element serving for acoustic decoupling, and a hose leading to the intake side of the internal combustion engine is plugged onto this end, which at the same time serves for axial fixation of the measuring tube in the air filter housing can be used if the measuring tube has a stop intended for contact with the inside of the housing wall.
  • the measuring tube can be made in one piece with the air filter housing.
  • a funnel can be attached to the inlet end for this purpose.
  • the funnel attached to the upper part of the air filter, can also serve as a second attachment point - with appropriate acoustic decoupling - for the air measuring tube.
  • the proposal according to the invention ensures that the air mass meter is protected from damage by its arrangement within the filter housing and that the risk of corrosion of the electrical contacts is reduced.
  • the air filter has a housing made of two half-shells 1, 2 on, which are held together by spring clips 3 and between them accommodate a plate-shaped filter element 4 which divides the interior of the filter housing into an unfiltered air chamber 5 and a clean air chamber 6.
  • the housing part 1 is provided with a connecting piece 7 for a hose leading to the front of the motor vehicle.
  • a hot wire or hot film air mass meter 8 is arranged in the clean air chamber 6 and has a measuring tube 9 with a hot wire or hot film 10. The signals of the measuring element 10 are fed via a plug 11 and a line 12 to the electronic control unit of the internal combustion engine.
  • the measuring tube 9 is inserted from the inside through an opening 13 of the housing part 2, in which a sealing ring 14 is used for sealing and acoustic decoupling.
  • a hose 16 which is fastened by a hose clamp 17 and leads to the intake side of the internal combustion engine, is pushed onto the end 15 of the measuring tube 9 protruding from the air filter housing.
  • the measuring tube 9 is provided with a stop 18 which bears on the inside of the housing part 2 or on the sealing ring 14 and together with the hose 16 ensures an axial fixing of the measuring tube 9 in the air filter housing.
  • a funnel-shaped component 20 is pushed onto the inlet end 19 of the measuring tube 9 in order to obtain optimal inflow conditions.
  • the funnel 20 serves as a second fastening point for the measuring tube 9, and for this purpose it has an extension 21 which is clipped into a counter element 22 on the housing part 2.
  • an elastic ring 23 is arranged between the funnel 20 and the measuring tube 9.
  • the funnel-shaped component 20 can also be in one piece with the measuring tube 9.
  • the arrangement of the air mass meter 8 within the air filter housing on the one hand reduces the space requirement and on the other hand protects the air mass meter from damage and corrosion.
