  • Adaptive muffler based on controlled flow valves
    Šteblaj, Peter ...
    An adaptive muffler with a flexible internal structure is con- sidered. Flexibility is achieved using controlled flow valves. The pro- posed adaptive muffler is able to adapt to changes in engine ... operating conditions. It consists of a Helmholtz resonator, expansion chamber, and quarter wavelength resonator. Different combinations of the control valvesʼ states at different operating conditions define the main working principle. To control the valveʼs position, an active noise control approach was used. With the proposed muffler, the transmission loss can be increased by more than 10dB in the selected frequency range.
