Definitions

  • the invention relates to a suction device for a Internal combustion engine according to the preamble of the main claim.
  • An intake device is known from EP 0 569 714 A1, an additional volume on the suction device to reduce noise provides that the intake air does not flow through becomes.
  • the shut-off device is located in one between two intake ducts located cross channel and is controlled by commands control electronics opened or closed.
  • the Control commands are dependent on the speed of the internal combustion engine and the temperature of the outside air with a temperature sensor is determined.
  • a disadvantage of the prior art is that it is not inconsiderable Part of the intake or damper volume switched off becomes or is not effective for the suction. at the scarcity of available space in the engine compartment This is disadvantageous in modern motor vehicles.
  • the invention has for its object a suction device for an internal combustion engine according to the generic term of the main claim to train so that for all operating conditions of the internal combustion engine and at the disposal standing space in the engine compartment optimal operating - in particular Noise conditions exist.
  • the suction device according to the invention solves the posed Task with those specified in the indicator of the main claim Features.
  • the suction device according to the invention is advantageous in that that the volume of the aspirator overall always is effective, but the noise-reducing effect is so can be varied so that the optimal damping distributed several speed ranges with different effects can be.
  • the intake pipe can be opened easily in the damper volume.
  • the volume size Defined Helmholtz resonator effective, the Promotes spread of a certain sound frequency range and dampens another area.
  • a branch pipe interference pipe
  • certain sound frequencies depending on the length of the branch pipe, selectively damped become.
  • the embodiment according to claim 4 describes the flexible Possibility of switching the desired sizes and the physical Damping volume properties. This switching technology does good through its adaptability acoustic properties of the internal combustion engine or Motor vehicle. The required switching effort is below Utilization of the other aggregates of a motor vehicle to realize according to claim 5 in a simple manner. costly and expensive accessories outside the suction device are not required according to the invention.
  • FIG 1 is a suction device 1 for one here Internal combustion engine, not shown, shown by the an air flow according to arrow 2 is sucked through an air filter 3 becomes.
  • An intake pipe 4 leads after the air filter 3 through a damping volume 5 to a throttle valve actuator 6 and ultimately to the intake manifold 7 of the internal combustion engine. Is between the air filter 3 and the damping volume 5 an additional channel 8 is arranged.
  • a flap inside the damping volume 5 10 for closing the additional channel 8 a pipe switch 11 for opening the intake pipe 4 into the interior of the damping volume 5 and a branch pipe 12 from the intake pipe 4, a predetermined length parallel to the intake pipe 4, however opposite to air flow 2, runs and is open at the end is.
  • the damping volume is shown in FIG. 1 Large area connected to the air filter 3 because the flap 10 to the additional channel 8 is open.
  • the one mentioned above Helmholtz resonance is therefore open from the sum of all Volumes determined and correspondingly low frequency.
  • FIG. 4 in which the size of the sound emission (dB (A)) is dependent indicated by the speed (rpm) in all operating modes is.
  • a curve 21 according to FIG. 4 shows an example of the proportionality large damping in the lower speed range.
  • FIG 2 a switching position is shown in which both the flap 10 to the additional channel as well as the pipe switch 11 are closed.
  • the damping volume 5 acts as Helmholtz resonator in the bypass, as a coupling element of the intake pipe 4 to the damping volume 5 only the branch pipe 12 comes into consideration.
  • Such shunt resonators are suitable by a suitable length of the branch pipe 12, specific noise components or sound frequencies selectively dampen. This is the sound position according to Figure 2 suitable for this in the entire speed range to be used.
  • Figure 4 is a course 20 of the noise emission over the speed in one design the branch pipe 12 at a shunt resonance of 40Hz, shown to attenuate very low sound frequencies.
  • the representation according to FIG. 3 is a Switch position for a two-chamber volume in which the Damping volume 5 and the volume of the air filter 3 in a row are switched.
  • By opening the pipe switch 11 and the closing of the additional channel 8 are the two Chambers each coupled via a damper neck. It is a series connection of two separate Helmholtz resonators that become one Attenuation leads in particular to the high sound frequencies.
  • the course of the sound emission in this switch position is shown in FIG. 4 as curve 22.
