Claims (2)

1. Vorrichtung zur Beeinflussung des Schalls im Ansaug­ trakt (AT) eines Verbrennungsmotors (VM), bei der
  • - die einen Saugpuls verursachenden Betriebszustände im Ansaugtrakt (AT) und/oder am Verbrennungsmotor (VM) erfassbar und der Schall durch eine Beeinflussung der akustischen Verhältnisse im Ansaugtrakt (AT) vermin­ derbar ist, dadurch gekennzeichnet, dass
  • - die Vorrichtung (ANC) eine derart steuerbare Schall­ quelle enthält, dass sich zwischen der Schallquelle und dem Verbrennungsmotor (VM) eine stehende Welle (W) ausbildet, die zu Aufladungseffekten im Verbren­ nungsmotor (VM) heranziehbar ist.
1. Device for influencing the sound in the intake tract (AT) of an internal combustion engine (VM), in the
  • - The operating states causing a suction pulse in the intake tract (AT) and / or on the internal combustion engine (VM) can be detected and the sound can be reduced by influencing the acoustic conditions in the intake tract (AT), characterized in that
  • - The device (ANC) contains a controllable sound source that forms a standing wave (W) between the sound source and the internal combustion engine (VM), which can be used for charging effects in the combustion engine (VM).
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass
  • - die Schallquelle in räumlicher Nähe zum Saugrohr des Verbrennungsmotors (VM) angeordnet ist.
2. Device according to claim 1, characterized in that
  • - The sound source is arranged in close proximity to the intake manifold of the internal combustion engine (VM).
