Definitions
- the present invention relates to an exhaust system with an exhaust gas purification component, an exhaust pipe, a connection device and a fastening element.
- a motor vehicle with an exhaust system and a method for operating the motor vehicle is specified.
- Exhaust gas purification components may have different functions in exhaust systems of internal combustion engines.
- the exhaust gas purification components are used as catalyst carrier bodies, as adsorbers, as filters, as flow mixers and / or as particle separators.
- These exhaust gas purification components typically have passages or channels through which a fluid can flow, which if appropriate are at least partially (catalytically) coated and / or formed with a filter material.
- the exhaust gas which flows into a channel can also be caused by deflection structures to partially pass through the channel walls, so that, for example, filter materials or deposition surfaces for particles and / or intimate contact with a catalytically active surface are achieved.
- the deposited soot particles, ash and / or carbon particles can be reacted at least temporarily by high exhaust gas temperatures, in the presence of NO 2 (nitrogen dioxide) and / or by a catalytically active coating.
- the object of the invention is therefore to solve the problems described with reference to the prior art at least partially and in particular to provide an exhaust system with the elimination of non-convertible into gaseous particles (such as ash) from the critical areas of the exhaust system can be done.
- an exhaust system with at least one exhaust gas purification component, at least one exhaust pipe, at least one connecting device for connecting the exhaust system to an internal combustion engine of a motor vehicle and at least one fastening element for additional fastening of the exhaust system to the motor vehicle, wherein at least one exhaust gas cleaning component in a mounted state to vibrations with a first resonance frequency range of less than 300 Hz [1 / sec], preferably of less than 150 Hz can be excited, wherein the exhaust gas cleaning component in a fixed state is preferably excitable to vibrations with a first resonant frequency range of at least 50 Hz.
- An exhaust gas purification component is understood in particular to mean at least one of the following components: honeycomb body, filter, separator, catalyst carrier body, adsorber and flow mixer.
- This exhaust gas purification components are arranged in the exhaust pipe or an exhaust gas recirculation line of an internal combustion engine associated exhaust system and thus exposed to the exhaust gas.
- Under a connection device such elements are understood, via which the exhaust system is directly connected or contacted with the internal combustion engine.
- the connecting device can be designed as a flange which is screwed to the internal combustion engine.
- the connecting device can also be realized via a welded joint of the exhaust system with the internal combustion engine.
- the connecting device is usually followed by the exhaust gas line, through which the exhaust gas is guided and in which the at least one exhaust gas purification component is arranged.
- the exhaust system is connected via at least one further fastening element to the motor vehicle.
- the at least one fastening element can produce a rigid or elastic connection of the exhaust system to the motor vehicle.
- the at least one fastening element is provided in particular on the underbody of the motor vehicle and comprises z. B. at least one holder which fixes the exhaust system away from the internal combustion engine in the desired position.
- the exhaust system Under a fastened state is understood in particular that the exhaust system is clamped to the connecting device and the at least one fastener according to the intended use. To determine the resonance frequency, the exhaust system is thus either mounted as intended in a motor vehicle or clamped in a test stand as in the intended use.
- the resonance frequencies of the at least one exhaust gas purification component of the exhaust gas system can be determined by numerical methods in simulations. In addition, an experimental determination of the resonance frequencies of the exhaust gas cleaning components arranged in the exhaust system is also possible.
- the exhaust system is clamped as in the operation of the internal combustion engine, for. B. in up to three (3) mutually orthogonal directions successively excited by a vibration source having an amplitude of at least 1 mm [millimeters] in the spatial direction.
- the vibration source passes through an excitation frequency of z. 1 Hz up to 16,000 Hz.
- a vibration amplitude is recorded at various points of the exhaust system, in particular at the exhaust gas purification components, as a function of the excitation frequency.
- the frequency at which maximum amplitudes are determined is called the resonant frequency.
- the resonant frequency range is a 10 Hz, preferably 5 Hz, more preferably 2 Hz, wide frequency interval, which centrally surrounds the resonant frequency.
- the resonance for the frequency range across the half-width of the resonance frequency can be determined in a representation of the oscillation amplitude by exciting the frequency, the resonance frequency range being at most 10 times, preferably at most 5 times, particularly preferably at most 3 times the half width equivalent.
- the exhaust system can be excited by vibrations to vibrations.
- the vibrations can be characterized at a given location of the exhaust system by an amplitude and a frequency.
- the amplitude and the frequency do not have to match at all locations of the exhaust system.
- Vibrations with frequencies in a first resonant frequency range are, in particular, those oscillations which an exhaust-gas purification component as a whole carries out, that is to say in particular those oscillations with which a housing of the exhaust-gas-cleaning component oscillates from its rest position. With the vibrations the housing from its rest position swing with all components of the emission control component. Damped mounted in the housing components may oscillate with a lower amplitude than the housing itself.
- vibrations with a frequency in the first resonant frequency range are transmitted to all components unattenuated.
- rigid structures of the emission control system such as the housing oscillate with a relatively small amplitude
- soft elements of the exhaust gas purification component such as the filter material
- swing with a larger amplitude As a result of the vibrations of the exhaust gas purification component, the ash particles and / or soot particles deposited in the exhaust gas purification component are thus also excited to oscillate. Due to their different inertia from the attachment point, the deposited particles can detach from the point of contact and reach, for example, the surface. B. back into the exhaust stream.
- the exhaust gas purifying component By exciting the exhaust gas purifying component at a frequency in the first resonance frequency range, the exhaust gas purifying component carries out vibrations having a large amplitude, thereby releasing the particles from their attachment sites.
- the first resonance frequency range of less than 300 Hz and in particular of less than 150 Hz is selected so that at least one exhaust gas cleaning component can be excited to vibrate, at least when starting or stopping the internal combustion engine by vibrations of the internal combustion engine. Since the internal combustion engine undergoes vibrations at frequencies from 0 Hz to frequencies of 300 Hz, which can be assigned to the idling speed at startup, the exhaust gas purification component is cleaned at least once during operation of the internal combustion engine by the vibrations.
- the resonance frequency range is more than 50 Hz, excitation of vibrations of the exhaust gas purifying component by vibrations resulting from road irregularities during running is prevented.
- frequencies from the first resonant frequency range are achieved by designing at least two of the following components:
- the mechanical properties of the aforementioned components are thus matched to one another such that a first resonance frequency range of less than 300 Hz or even less than 150 Hz is realized.
- mechanical properties is meant in particular the mass, the flexural strength, the modulus of elasticity of the components and / or their joints.
- the at least one exhaust gas purification component for a fluid through which can flow channels having walls which are formed at least partially with filter material and a plurality into the channels hineinra- ing structures.
- the fluid flowing in one passage may flow to an adjacent passage through a filtering material which receives the particulates and / or the ashes.
- the channels are arranged in layers.
- the exhaust gas can thus be deflected in two orthogonal directions. It is advantageous if the at least one exhaust gas purification component can oscillate in at least one of the deflection directions.
- the soot particles and / or carbon particles deposited in the filter material can be accelerated in both directions from the rest position to a channel.
- the at least one exhaust gas cleaning component has at least one component which has a second resonant frequency range of more than 500 Hz, preferably more than 800 Hz, particularly preferably more than 1000 Hz.
- the second resonance frequency range characterizes a component of the exhaust gas purification component itself.
- the components of the at least one exhaust gas purification component are in particular the structures and / or the walls of the channels, in particular the filter material. The second resonant frequency range is thus outside of the vibration frequencies normally generated by an internal combustion engine.
- the components of the exhaust gas purification component are thus alone (that is, in particular without a corresponding resonance oscillation of the exhaust pipe in this area) just not excitable by the internal combustion engine to vibrations, whereby an unwanted excitation of the components is avoided to vibrations while driving.
- the second resonant frequency range is determined, in particular, by the fact that the clamped exhaust gas cleaning component is excited with vibrations, wherein the vibrations of the individual components are recorded as a function of the frequency of the exciting oscillations. It is advantageous if the at least one exhaust gas purification component is assigned a vibration element which can excite the exhaust gas purification component to oscillate at a frequency in the second resonance frequency range. As a result of the vibrations, the particles deposited in the exhaust gas purification component are separated from the adsorption set solved. With the aid of the vibrating element, the exhaust gas purifying component can be specifically cleaned during operation of the internal combustion engine in addition to the vibrations caused by the internal combustion engine during starting and stopping.
- a method for operating a motor vehicle with an internal combustion engine and an exhaust system wherein the internal combustion engine is operated during the starting process so that vibrations of the internal combustion engine are excited so long that they are transmitted to an exhaust gas purification component, which are excited to vibrations in a resonant frequency range of less than 150 Hz, so that it is freed of particles.
- an exhaust gas purification component which are excited to vibrations in a resonant frequency range of less than 150 Hz, so that it is freed of particles.
- Fig. 1 a motor vehicle with an exhaust system according to the invention
- the exhaust system 1 shows schematically a motor vehicle 6 with an internal combustion engine 5 and an exhaust system 1.
- the exhaust system 1 has an exhaust pipe 3 with two (integrated) exhaust gas purification components 2, a connection device 4 and two fastening elements 7.
- the Exhaust system 1 is connected via the connecting device 4 to the internal combustion engine 5 and connected via the fastening elements 7 in addition to the motor vehicle 6.
- On the exhaust pipe 3 detectors 17 are further arranged, which are connected via data lines 18 to a control unit 19.
- the one exhaust gas purification component 2 is further associated with a vibrating element 9, which is also connected via the data line 18 to the control unit 19.
- the control unit 19 is also connected to the internal combustion engine 5.
- the mechanical properties of the exhaust gas purification component 2, the exhaust pipe 3, the connecting device 4 and the fastening element 7 are coordinated so that at least one exhaust gas cleaning component 2 has a first resonant frequency range of below 300 Hz or even below 150 Hz, but above 50 Hz up. In this way it is ensured that when starting the internal combustion engine 5 by transferring the vibrations of the internal combustion engine 5 to the exhaust system 1, which is at least one exhaust gas cleaning component 2 is vibrated, so that in the exhaust gas purification component 2 deposited particles are released. An excitation of vibrations due to road bumps while driving is avoided. Exciting the exhaust gas purifying component 2 to vibrations during idling of the internal combustion engine 5 and / or under load can thus be practically avoided (if desired).
- the control unit 19 controls the injection processes in such a way that oscillations with frequencies from a first resonant frequency range are preferably excited.
- the detectors 17 determine parameters of the exhaust gas such as pressure, temperature and / or exhaust gas composition, in the exhaust pipe 3 and send them to the control unit 19.
- the control unit 19 can after predetermined intervals and / or at predetermined parameters of the internal combustion engine 5 and / or predefinable Parameters of the exhaust gas, the vibrating element 9 a signal for carrying out vibrato give onen.
- the vibrating element 9 in particular carries out vibrations with frequencies greater than 500 Hz [1 / sec].
- the frequency of the exciting vibration can be adjusted so that the exhaust gas purification component 2 is excited at a frequency in a second resonant frequency range of the components 8 of the exhaust gas purification component 2.
- the exhaust gas purifying component 2 may be excited alternately at different frequencies by the vibrating element 9.
- the exciting amplitude of the vibrating element 9 is preferably less than 1 mm.
- the exhaust gas purification component 2 is carried out during operation of the internal combustion engine 5, so that in the exhaust gas purification component 2 deposited, unreacted in a regeneration, particles are dissolved and entrained by the exhaust gas flow of the internal combustion engine.
- the vibrating element 9 may be, for example, a piezoelectric element or an electric motor.
- the exhaust gas purification component 2 shows a section of an exhaust gas purification component 2.
- the exhaust gas purification component 2 has channels 11, into which the exhaust gas flows in an original flow direction 16.
- the channels 11 are formed by channel walls 13 which have passages 15 and are partially formed by filter material 12.
- the channel walls 13 may include structures 14 (eg, corrugated metal foils) that redirect the exhaust gas.
- the arrows indicate the flow direction of the exhaust gas.
- the exhaust gas carries particles 10 with it and is deflected by the structures 14 such that the particles 10 can deposit in the filter material 12. As a rule, soot particles and ash are converted during the regeneration of the exhaust gas purification component 2 to carbon dioxide and nitrogen.
