Der Erfindung liegt die Aufgabe zugrunde einen Abgasschalldämpfer für eine zweiflutige Abgasanlage einer Brennkraftmaschine derart auszugestalten, dass wahlweise einerseits eine automatische Geräuschpegelbeeinflussung in Abhängigkeit der Betriebsbedingungen, insbesondere Drehzahl und/oder Drehmoment, der Brennkraftmaschine, und andererseits eine willkürliche Geräuschmodulation für die Erzielung eines sog. sportlichen Abgasgeräusches erreicht werden kann.The invention has for its object an exhaust muffler for a double-flow exhaust system of an internal combustion engine to design such that either on the one hand an automatic noise level control function of operating conditions, in particular speed and / or torque of the internal combustion engine, and On the other hand, an arbitrary noise modulation for the achievement of a so-called. Sporty exhaust noise can be achieved.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Weitere, die Erfindung ausgestaltende, zweckmäßige oder vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object is achieved by the features specified in
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass es bei Einsatz geringer technischer Mittel möglich ist, eine im Sinne einer Komfortsteuerung optimale Minimierung des Abgasgeräusches zu erreichen. Vor allem ermöglicht eine unmittelbare Ansteuerung des einen Stellmotor bildenden Hilfsmotors in Abhängigkeit von Betriebsbedingungen der Brennkraftmaschine die Verwendung ohnehin in elektronischer Form vorliegender Daten zur Ansteuerung der Verstellung der Durchgangsöffnungen in der Trennwand des Abgasschalldämpfers, und zwar dergestalt, dass zumindest über einen auswählbaren Drehzahlbereich bzw. eine auswählbare Drehmomentanforderung hin eine selbständige Optimierung der Dämpfungscharakteristik des Abgasschalldämpfers erfolgen kann. Dies beruht hauptsächlich darauf, dass sich aus der Verwendung der Daten der Betriebsbedingungen der Brennkraftmaschine die Möglichkeit einer Veränderung der Betriebsbedingungen der Brennkraftmaschine automatisch und unmittelbar, d. h. verzögerungsfrei ergibt.The advantages achieved by the invention are to be seen in the fact that it is possible when using low technical means to achieve optimal in terms of comfort control minimization of the exhaust noise. Above all, an immediate control of a servomotor forming a servomotor depending on operating conditions of the internal combustion engine, the use anyway existing in electronic form data for controlling the adjustment of the through holes in the partition of the exhaust muffler, in such a way that at least over a selectable speed range or a selectable torque request towards an independent optimization of the damping characteristic of the exhaust muffler can be done. This is mainly due to the fact that from the use of the data of the operating conditions of the internal combustion engine, the possibility of a change in the operating conditions of the internal combustion engine automatically and directly, d. H. results without delay.
Zur Erzielung einer praktisch verzögerungsfrei und vorzugsweise stufenlos vorzunehmenden Veränderung der lichten Öffnungsweiten der Durchgangsöffnungen in der Trennwand empfiehlt sich der Einsatz von Schiebern und deren Antrieb durch einen mit einem Untersetzungsgetriebe ausgestatteten, drehrichtungsumkehrbaren Elektromotor, wobei je nach Ausbildung des Schiebers als Drehschieber oder als linear hin- und hergehender Schieber eine geeignete Kraftübertragung, Welle oder Kurbeltrieb, vorgesehen sein kann.To achieve a practically delay-free and preferably infinitely variable change of the clear opening widths of the passage openings in the partition, the use of slides and their drive by a equipped with a reduction gear, reversible electric motor recommended, depending on the design of the slide as a rotary valve or as linear hin-. and forthcoming slide a suitable power transmission, shaft or crank mechanism, can be provided.
In einer bevorzugten Verwirklichungsform wird der die wirksame lichte Weite der Durchgangsöffnungen in der Trennwand beherrschende Schieber in Abhängigkeit von der aktuellen Motordrehzahl der Brennkraftmaschine derart angesteuert, dass bei niedrigen Drehzahlen und niedrigem Drehmoment und auch bei hohen Drehzahlen und hohem Drehmoment die beiden Kammern des Abgasschalldämpfers durch Verschließen der Durchgangsöffnung in der Trennwand vollständig gegeneinander abgeschottet sind, während die Durchgangsöffnung in der Trennwand in der unteren Hälfte eines mittleren Drehzahlbereiches der Brennkraftmaschine bei ansteigendem Drehmoment und ansteigender Drehzahl völlig freigegeben und die Durchgangsöffnung ausgehend von der unteren Hälfte des mittleren Drehzahlbereiches zu höheren Drehzahlen und steil ansteigendem Drehmoment hin stufenweise oder kontinuierlich verschlossen wird.In a preferred embodiment of the actual clear width of the through holes in the partition dominant slider is controlled in response to the current engine speed of the engine so that at low speeds and low torque and at high speeds and high torque, the two chambers of the exhaust muffler by closing the passage opening in the partition wall are completely sealed off from each other, while the passage opening in the partition in the lower half of a middle speed range of the internal combustion engine with increasing torque and increasing speed completely released and the passage opening from the lower half of the middle speed range to higher speeds and steeply rising Torque is closed gradually or continuously.
Eine besondere, als Sportmodus abgewandelte Gestaltungsform, die weniger auf eine größtmögliche Dämpfungscharakteristik sondern vielmehr auf eine gewisse, vielfach als angenehm empfundene Klangform des Abgasgeräusches abzielt, sieht vor, dass die drehzahlabhängige Ansteuerung des Öffnens oder Verschließens der Durchgangsöffnung in der Trennwand zwischen den beiden Kammern des Abgasschalldämpfers von einem Signal für eine, beispielsweise durch die Gangwahl oder die Fahrpedalbetätigung ausgedrückte Fahreranforderung bezüglich eines höheren Drehmomentes oder einer Erhöhung der Motorleistung, insbesondere im volllastnahen Bereich, zumindest teilweise übersteuert werden kann.A special, modified as a sport mode design, which aims less at a maximum damping characteristic but rather on a certain, often perceived as pleasant sound shape of the exhaust noise, provides that the speed-dependent control of opening or closing the passage opening in the partition between the two chambers of the Exhaust silencer of a signal for a, for example, by the gear selection or the accelerator pedal operation expressed driver demand for a higher torque or an increase in engine performance, especially in the full load area, at least partially overridden.
