Definitions

  • the invention relates to a holder for an intake manifold system according to the preamble of claim 1.
  • an engine component with the highest structure-borne noise levels is the cylinder head, which is mainly excited by excitation from the combustion and the gas exchange control.
  • This structure-borne noise level means that considerable noise is emitted through the relatively large surfaces of the suction pipes.
  • these noises are superimposed by high-frequency, pulse-like ticking noises at low engine speeds, some of which are emitted by the cylinder head, the intake manifolds and the fuel manifold, and some are also radiated directly from the surface of the injection valves. Every time the residual engine noise is reduced, the ticker noises mentioned are subjectively disturbing.
  • a sleeve-shaped receptacle made of elastic material for an injection valve is known, which is formed in one piece with a connecting pipe element and encloses the valve on the foot side, the other area of the valve being exposed except for the contact with the pipe element.
  • a sleeve-shaped receptacle for an injection valve on a metallic suction pipe is known, which is made in one piece with it and in which the valve is held on the foot side.
  • the object of the invention is to provide a holder for an intake manifold system of an internal combustion engine of the type mentioned at the outset, with which additional noise-reducing effects on the internal combustion engine can be achieved. Furthermore, the attachment of the intake manifold on the cylinder head side should be permanent, secure and of high strength.
  • an elastically designed tubular element preferably made of another elastic material, such as thermoplastic, is provided between the cylinder head and the intake lines, which at the same time has an encapsulating and structure-borne noise-isolating receptacle for an integrated injection valve.
  • the proposed pipe element is used for effective structure-borne noise insulation of the intake manifolds of the cylinder head, whereby the noise emission is reduced.
  • the pipe section is used to record an injection valve to isolate structure-borne noise. This prevents high-frequency, pulse-like ticking noises, namely airborne sound insulation through the encapsulating enclosure, structure-borne noise insulation of the injection valve of the cylinder head and intake manifold, and structure-borne noise attenuation through the tightly enclosing elastomer sleeve.
  • An intake manifold system of an internal combustion engine comprises a plurality of intake lines 1, each of which is connected to a cylinder head 3 of the internal combustion engine via a flange 2. Between the cylinder head 3 and the individual intake lines 1, a structure-borne sound insulating connecting pipe element 4 is provided. It consists of an elastic material, preferably an elastomer.
  • a flange 2 made of the material of the connecting pipe element 4 is used, which is reinforced with a stiffening part 5 made of steel or an equivalent material.
  • Bushings can also be provided in the flange, which are molded into the elastomer flange 2.
  • connection of the elastic connecting pipe element 4 to the metallic suction line 1 is either carried out by clamping rings 6, as shown, or the pipe is injection molded onto the suction line 1 by a known method.
  • a sleeve-shaped receptacle 7 for a fuel injection valve 8 is provided on the elastic connecting pipe element 4.
  • the receptacle 7 is made in one piece with the connecting tube element 4 and forms a capsule for the valve 8 and for this purpose is pulled up as far as possible according to the length of the valve.
  • Corresponding molded beads 9 are provided within the receptacle for the form-fitting mounting of the valve 8.
  • the receptacle 7 is designed in such a way that it tightly encloses the valve and covers the entire noise-radiating surface.
