Definitions
- the invention relates to an internal combustion engine, in particular for a motor vehicle a supercharger which compresses a charge air and which has a compressor pressure connection has, an intake tract, the compressor pressure port of the charger with the Intake tract connecting the charge air hose and one in the air flow of the charge air arranged silencer, according to the preamble of claim 1.
- a charge air hose for an internal combustion engine is used to conduct charge air a charger, for example an exhaust gas turbocharger, directly or via a Charge air cooler to an intake tract of the internal combustion engine.
- a charger for example an exhaust gas turbocharger
- Charge air cooler to an intake tract of the internal combustion engine.
- Such one Charge air hose is known from DE 195 06 584 C1 and consists of a flexible Material to measure relative movements between the charger and the charge air cooler To be able to compensate for the internal combustion engine.
- the well-known charge air hose is also provided with folds whose outer diameter is larger than the outer diameter of the charge air hose. In these folds there is one inside the charge air hose annular rigid insert introduced, whereby the axial elongation of the Charge air hose under internal pressure and thus the transfer of forces between the Components should be reduced.
- the present invention is therefore based on the object, a charged Internal combustion engine of the above type with improved charge air supply To make available.
- the noise damper in a clutch is integrated between the charge air hose and the compressor pressure port so that the Muffler on the one hand in the compressor discharge nozzle and on the other hand in the Charge air hose engages.
- the noise damper has an inner tube, which forms a first and a second outer chamber, the first chamber engages in the compressor pressure nozzle and with it via at least one first opening is connected and the second chamber engages in and with the charge air hose at least one second opening is connected, the inner tube also being in two parts is formed, wherein a first part of the first outer chamber and a second part forms the second outer chamber and the two parts at a joint each bent into a flange and connected to each other on the flange, in particular are welded together.
- the noise damper has an outer contour, which surrounds the inner tube and is located downstream of the second chamber in the Inner diameter narrowed and together with the charge air hose a third outer one Chamber trains.
- the outer contour comprises one upstream of the first chamber Faceplate.
- the charge air hose is in the area of the second outer chamber on the Outer contour and this spanned and the compressor discharge nozzle is in Area of the first outer chamber on the outer contour and overlapping this executed.
- the outer contour is also formed in two parts, with a first part first outer chamber and a second part encloses the second outer chamber and the two parts being bent and joined at a joint to form a flange the flange connected to each other and to the flange of the parts of the inner tube, in particular are welded together.
- the charger is an exhaust gas turbocharger, a pressure wave charger or a mechanical loader.
- Fig. 1 is the connection point between a compressor discharge nozzle 10 and a Charge air hose 12 of an internal combustion engine, which is otherwise not shown in detail shown.
- the compressor pressure nozzle 10 comes from a charger, not shown and the charge air hose 12 leads to an intake tract, not shown Internal combustion engine, optionally with an intercooler between the charge air hose 12 and intake tract is arranged.
- a noise damper formed which comprises: an inner tube 14 having a first part 16 and second part 18 and an outer contour 20, which is also a first part 22 and a has second part 24.
- the first part 16 of the inner tube 14 forms a first outer Chamber 26 out and is with the compressor discharge nozzle 10 via a first slot 28th connected.
- the second part 18 of the inner tube 14 forms a second outer chamber 30 and is connected to the charge air hose 12 via a second slot 32.
- On a joint 34 between the first and second parts 16, 18 are flange-like formed or molded and welded together.
- the first part 22 of the outer contour 20 surrounds the first chamber 26 and is a contour of the compressor pressure connector 10 following. Upstream of the first outer Chamber 26 has an end plate 36 arranged on the first part 22 of the outer contour 20. This end plate 36 is optionally also in one piece with the first part 22 of the outer contour 20 trained.
- the first part 22 of the outer contour 20 is also at the joint 34 formed like a flange and with corresponding flange sections 38 of the inner tube 14 welded. This section of the noise damper 16, 22 just described 26, 28, 36, which lies in the single figure to the right of the joint 34, projects completely into the compressor pressure connector 10 into it.
- the second part 24 of the outer contour 20 surrounds the second outer chamber 30 and narrows downstream of the second outer chamber 30 or the second slot 32 in Inner diameter such that between the narrowed part 40 of the outer contour 20 and the charge air hose 12 results in a third outer chamber 50.
- Section 40 the outer contour 20 surrounds an outlet 42 from the second outer chamber 30.
- the second part 24 of the outer contour 20 is also flange-like at the joint 34 formed and with the flange portions 38 of the inner tube 14 and with the Flange section of the first part 22 of the outer contour 20 welded. This just now described section of the silencer 18, 24, 30, 32, 40, 42, which in the only the left of the joint 34 protrudes completely into the charge air hose 12 into it.
- the silencer is except for the joint 34 within the charge air hose 12 or Compressor pressure connector 10 arranged and forms a coupling element. Consequently are the functions "internal coupling element between Compressor pressure nozzle 10 and charge air hose 12 "as well as” noise damper "in one integrated single component.
- At 48 are two recesses for one, not shown Clamp can be seen in which this clamp engages and which by means of Noise-damping coupling locked in the compressor discharge nozzle 10.
- the two outer chambers 26 and 30 are closed at the joint 34, so that no flow takes place here.
- the outer chambers 26 and 30 are closed at each of the joints 34 facing away.
- the third outer chamber 50 is only in the direction of Charge air hose open 12. In these chambers 26, 30, 50 it only happens vortex-like movements of the charge air. Overall, the system yields with the outer Chambers 26, 30, 50 in connection with the inner tube 14 a noise-damping Effect.
