Abstract

To increase engine' s dynamic performance, economic index and improve its exhaust, an experimental system used to cancel low-frequency noise of engine exhaust was put forward, and the noise cancellation mechanism of the system was also studied. The exprimential results demonstrated that the average noise level was decreased by more than 30 dB in low-frequency band.
