Definitions

  • the invention relates to an internal combustion engine with mechanical supercharging, wherein a compressor is supported via connecting elements on the cylinder block and wherein some of the components associated with the compressor are equipped with molded foam or a similar sound-absorbing material for reducing the sound radiation.
  • Out JP 06 108 942 is an internal combustion engine with V-shaped cylinder block and compressor charging known.
  • the compressor is arranged in the free space between the two rows of cylinders and supported by a configured as a resonator assembly on the cylinder block.
  • the arrangement and spatial orientation of the resonator should cause a reduction of the airflow noise.
  • JP 04 303124 Another engine with V-shaped cylinder block and compressor supercharging will be described. This opens two bypass lines, which bridge the compressor or the intercooler in a common and operatively connected to the compressor line. This line and the compressor are structurally integrated into a common housing, which is arranged in the free space between the two rows of cylinders and to ensure a reduced sound radiation.
  • JP 11-315,724 is an internal combustion engine with compressor supercharging, in which a damping chamber is configured in a bypass line bridging the compressor.
  • the outside of the damping chamber is covered with a sound absorbing material, such as glass wool.
  • JP 63-309,762 is described a supercharged internal combustion engine having a plurality of assemblies with noise-absorbing elements.
  • the inner walls of the air filter housing are clad with components made of molded foam and the compressor is at least partially disposed in a housing, on the insides of which noise-absorbing fabric structures are applied.
  • the object of the invention is therefore to reduce in an internal combustion engine with charging the sound emission caused by the compressor by assigning specifically designed components with noise-absorbing properties.
  • a pulsation damper to the compressor on the suction side and the pressure side and wherein the compressor, the suction-side pulsation damper and the pressure-side pulsation damper are each covered with noise insulation, each having an inner component made of absorption foam and an outer component made of plastic.
  • the inner component of absorption foam alternatively as a separate molding or as a planar structure be designed.
  • the outer component made of plastic may alternatively be made in one piece or have a plurality of segments which are joined together by a clip connection, a screw connection or by a tongue and groove connection to a common spatial structure.
  • the sound radiation caused by the compressor its associated dampers is substantially reduced by an encapsulation of these noise-generating modules.
  • the encapsulation chosen here from lined with foam absorption trays can be produced inexpensively and assembled with little effort. As a result, virtually no compressor noise in the vehicle interior perceptible.
  • both the increasingly stringent legal requirements can be met in an advantageous manner and the increasing comfort demands of the vehicle users can be satisfied.
  • This technical solution is basically suitable for differently designed internal combustion engines, a preferred application here is the assembly on a side surface of the cylinder block of an engine with cylinders arranged in series.
  • a section of an internal combustion engine is shown with mechanical charging.
  • a compressor 1 is supported via connecting elements, for example with screws 2 on a cylinder block 3.
  • the compressor 1 is on the suction side and the pressure side each associated with a pulsation damper.
  • the compressor 1, the suction-side pulsation damper and the pressure-side Pulsationsdämpfer are each covered with a noise insulation.
  • This noise insulation has in each case an inner component made of absorption foam and an outer component made of plastic.
  • a preferred embodiment of the noise insulation for the pressure-side Pulsationsdämpfer can be seen.
  • a sound capsule 4 made of plastic is designed, on whose inner surfaces a dimensionally stable and the associated side surface of the compressor 1 cross absorption foam part 5 is supported.
  • the noise insulation for the pressure-side pulsation damper has a further dimensionally stable absorption foam part 6.
  • This absorption foam part 6 surrounds in a tubular manner a pressure damper stub 7 which is arranged outside the contour of the first absorption foam part 5.
  • the sound pressure capsule 4 associated with the pressure-side pulsation damper and / or the absorption foam part 5 assigned to this noise capsule 4 have openings 8. These breakthroughs 8 screws 2 can be assigned to fasten the compressor 1 on the cylinder block 3.
  • a noise insulation for the drive of the compressor 1 can also be configured as a sound capsule made of plastic. On the inner surfaces of such a noise capsule, a dimensionally stable and the belt tensioner area cup-shaped cross-over absorption foam part 9 can be supported, which is shown in Fig. 2.
  • a preferred embodiment in which the noise insulation for the main body of the compressor 1 is designed as a plastic noise capsule 10. On the inner surfaces of this noise capsule 10 is a dimensionally stable and the compressor 1 U-shaped cross-absorption foam member 11 is supported.
  • the noise insulation for the suction-side pulsation damper is preferably configured as a noise capsule 12 assembled from a plurality of segments of plastic. For this purpose, as shown in FIG. 6, for example, three related segments used.
  • the inner surfaces of the segments of the noise capsule 12 are each with Absorption foam lined, which is not shown in detail in the drawing.
  • FIGS. 4 to 6 the components mounted with one another and equipped with noise insulation are shown in different views, and FIG. 7 finally shows these components in an exploded view.
