Definitions

the invention relates to an intake manifold system according to the preamble of claim 1.
one of the engine components with the highest structure-borne noise levels is the cylinder head, which is mainly excited by excitations from combustion and 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 rail, but 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.
the object of the invention is to provide an intake manifold system of an internal combustion engine of the type mentioned at the outset with attached injection valves, in 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 an elastomer or 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 the injection valves from structure-borne noise and encapsulation. This prevents high-frequency, pulse-like ticking noises, namely airborne sound insulation through the encapsulating enclosure, structure-borne noise insulation of the injection valves 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 4 is provided. It consists of an elastic material, preferably an elastomer.
a flange 2 made of the material of the connecting tube 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 4 to the metallic suction line 1 is made either by clamping rings 6, as shown, or the pipe is molded onto the suction line 1 by a known method.
a sleeve-shaped receptacle 7 for an injection valve 8 is provided on the elastic connecting pipe 4.
the receptacle 7 is made in one piece with the connecting tube 4.
the receptacle 7 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.
