Definitions

  • the present invention relates to an exhaust system for an internal combustion engine, in particular in a motor vehicle, having the features of the preamble of claim 1.
  • the exhaust gases are often fed from the two cylinder banks via two manifolds in two exhaust lines to a common rear silencer or two separate mufflers.
  • the two exhaust strands run in the vehicle on the underbody in a tunnel which regularly has heat shields upwards and to the side. Down below, the underfloor clearance is an imaginary border of the tunnel dar.
  • a center silencer which must be located in the middle of the system. In this case, each exhaust tract a separate center muffler can be assigned.
  • both exhaust strands can be assigned a common middle silencer.
  • the respective middle silencer must also be accommodated in the tunnel, which regularly leads to space problems, since the respective Middle silencer must have a certain minimum volume in order to fulfill its acoustic function.
  • an exhaust system which has two separate exhaust lines for discharging exhaust gases of an internal combustion engine. Furthermore, the known exhaust system comprises a switchable sound transmission device, which couples the two exhaust gas lines for the transmission of airborne sound with each other. With the aid of a control device, the sound transmission device can be activated and deactivated, this being done as a function of at least one operating parameter of the internal combustion engine. In this case, for example, the rotational speed and / or the load of the internal combustion engine are suitable as operating parameters.
  • the known exhaust system is suitably operated so that at low speeds, the sound transmission device is active. Silencers associated with the exhaust lines are acoustically designed for noise frequencies that occur at low speeds. At higher speeds, the sound transmission device is deactivated, whereby the effective interference frequencies due to the targeted assignment of the separate exhaust lines to individual cylinders of the internal combustion engine is halved. Thus, for two speed ranges, which are related to each other via the interference frequencies, an effective sound attenuation can be achieved.
  • the disadvantage here is the limitation of the damping effect on only two speed ranges. Furthermore, the activation of the sound transmission device at low Speeds resulting from adverse effects on the charge cycle in the cylinders of the internal combustion engine to a reduction in the available engine torque lead.
  • the present invention deals with the problem, for an exhaust system of the type mentioned, to provide an improved embodiment, which is particularly characterized in that, for example, at low engine speeds more torque is available and / or that increased variability for the adjustment the damping effect can be realized and / or that the required space is reduced.
  • the invention is based on the general idea of being able to acoustically couple the two exhaust gas strands with two switchable sound transmission devices, which are arranged spaced apart in the exhaust gas flow direction.
  • two switchable sound transmission devices which are arranged spaced apart in the exhaust gas flow direction.
  • an increased variability for the adjustable switching states can be realized.
  • at least three different switching states namely a first switching state in which both sound transmission devices are deactivated, a second switching state in which activates the one sound transmission device is while the other sound transmission device is deactivated and a third switching state in which both sound transmission devices are activated. It has been found that the different switching states result in significant effects on the torque of the engine equipped with the exhaust system.
  • the torque can be significantly increased if this low rotational speed of the internal combustion engine is assigned, ie operating states in which a high torque is particularly desirable.
  • the attenuation effect of the exhaust system is better a-daptierbar to different operating conditions of the internal combustion engine by the three different switching states.
  • the damping effect of the exhaust system can be improved to the extent that it can be dispensed with in certain applications on a middle silencer. The associated with the installation of a middle silencer space problems can be avoided.
  • An embodiment has proven to be particularly advantageous in which the upstream first sound transmission device is deactivated in the second operating state, while the downstream second sound transmission device is activated.
  • the torque can be increased for average speeds.
  • a control device assigns the switching states to different speed ranges.
  • the first switching state is associated with a lower speed range
  • the second switching state is associated with a medium speed range
  • the third switching state is associated with an upper speed range.
  • an exhaust system 1 comprises two separate exhaust lines 2 and 3.
  • the exhaust system 1 serves to dissipate the exhaust gases in an internal combustion engine 4, which may be arranged in particular in a motor vehicle.
  • the two exhaust gas lines 2, 3 are assigned to different cylinders 5 of the internal combustion engine 4. In the example, a six-cylinder engine is shown without loss of generality.
  • the two exhaust gas lines 2, 3 are each assigned to a group of cylinders 5 which are selected such that the cylinders 5 of one cylinder group and the cylinders 5 of the other cylinder group have their working strokes alternating.
  • the cylinder groups can be selected so that parallel-acting cylinders are each arranged in different cylinder groups. This is especially true for larger engines, such as V-eight or V-twelve engines.
  • the exhaust system 1 also has a first switchable sound transmission device 7, which is designed so that it can couple the two exhaust gas lines 2, 3 for the transmission of airborne sound.
  • the exhaust system 1 according to the invention comprises a second switchable sound transmission device 8, which is designed such that it the two exhaust gas lines 2, 3 downstream of the first Sound transmission device 7 can couple to each other for the transmission of airborne sound.
  • a control device 9 For switching or for actuating the two sound transmission devices 7, a control device 9 is provided. This is designed so that it can control the two sound transmission devices 7, 8 as a function of at least one operating parameter of the internal combustion engine 4 for activating and deactivating.
  • the activated state a sound transmission between the two exhaust lines 2, 3 by the respective sound transmission device 7, 8.
  • the deactivated state the sound transmission between the two exhaust lines 2, 3 is omitted by the respective sound transmission device 7, 8.
  • the control device 9 is also according to the invention configured so that it can control the two sound transmission devices 7, 8 in response to the at least one operating parameter of the internal combustion engine 4 for the realization of at least three different switching states. In a first switching state, both sound transmission devices 7, 8 are deactivated.
  • the control device 9 controls the sound transmission devices 7, 8 for realizing the second switching state such that the upstream first sound transmission device 7 is deactivated and that the downstream second sound transmission device 8 is activated.
  • the control device 9 preferably uses a rotational speed of the internal combustion engine 4 in order to actuate the sound transmission devices 7, 8 as a function of the rotational speed.
  • control device 9 is configured so that it divides the speed range of the internal combustion engine 4 in total into three speed ranges. In a lower speed range, the control device 9 actuates the sound transmission devices 7, 8 for setting the first switching state. In a medium speed range, the control device 9 adjusts the second switching state at the sound transmission devices 7, 8. In an upper speed range, the control device 9 then realizes the third switching state.
  • the corresponding speed information is received by the control device 9, e.g. from an engine control unit, not shown here.
  • the control device 9 can be integrated into the hardware of such an engine control unit or implemented in software.

  • Fig. 2 In principle, it is possible to equip the exhaust system 1 with at least one middle silencer 14, which in particular can be assigned jointly to both exhaust lines 2, 3. Depending on the application and depending on the design of the exhaust system 1, it is by the use of the two sound transmission devices 7, 8 according to Fig. 1 possible to dispense with such a middle silencer 14 and yet to ensure adequate sound attenuation.
  • the first sound transmission device 7 at the two exhaust gas lines 2, 3 downstream the catalysts 10 are arranged. Furthermore, the first sound transmission device 7 is located upstream of the silencer 12. The second sound transmission device 8 is arranged on both exhaust gas lines 2, 3 upstream of the two silencers 12. In addition, the second sound transmission device 8 is located downstream of the first sound transmission device 7 and thus downstream of the catalysts 10.
