Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Beeinflussung des Schalls im Ansaugtrakt eines Verbrennungsmotors, bei dem die einen Saugpuls verursachenden Betriebszustände im Ansaugtrakt (3) und/oder am Verbrennungsmotor (3) erfasst werden und der Schall durch eine Beeinflussung des Luftstroms (9) im Ansaugtrakt (3) vermindert wird. Die Beeinflussung des Luftstromes (9) wird durch einen zumindest teilweisen Verschluss des Strömungskanals im Ansaugtrakt (3) zu vorgegebenen, periodisch wiederkehrenden Zeiten bewirkt, in denen kein oder ein geringer Luftmassentransport im Strömungskanal stattfindet. Mit einem Steuerprogramm wird ein Steuersignal zur Amplituden- und Phasensteuerung hinsichtlich des Verschließens und Öffnens des Durchströmungsquerschnitts des Ansaugtraktes (3) zumindest in Abhängigkeit von der Drehzahl des Verbrennungsmotors (1) erzeugt.
