| 摘要 |
The present invention relates to a device to reduce an exhaust noise of an engine (12) of a diesel engine generator (10), comprising: an antiphase controller (30) mounted on the engine (12) adjacently arranged to the two diesel engine generators (10) to maintain a predetermined explosion timing; and a noise absorbing unit (40) to connect adjacently the exhaust manifold of the two engines (12) together. Therefore, the high and low-frequency noise can be reduced at the same time by making the outlet of the exhaust pipes adjacent to each other in comparison with the main noise wavelength to combine a noise having opposite phases at the starting point of the exhaust pipes. |
