Abstract

The embodiment of the invention provides a silencer and a vehicle. The silencer comprises a shell, a valve, a first pipeline and a second pipeline, wherein the first pipeline and the second pipeline are arranged in the shell, the shell is provided with a gas inlet and a gas outlet, the first end of the first pipeline communicates with the gas inlet, the second pipeline comprises a first sub-pipeline and a second sub-pipeline which communicate with each other, the first end of the first sub-pipeline communicates with the gas outlet, and the valve is arranged at the second end of the first sub-pipeline and used for opening or closing the first sub-pipeline. By changing the internal tuning structure of the silencer, an engine can achieve a high-quality noise effect at a low rotating speed, and can achieve high-performance output at a medium-high rotating speed.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a muffler and a vehicle. Background technique [0002] The muffler refers to the air duct with noise transmission at the same time, which can use noise reduction devices such as pipes and elbows with sound-absorbing linings or pipes with sudden changes in cross-sectional area and other pipes with discontinuous acoustic impedance to attenuate the noise in the pipe or Reflected back, so as to achieve the effect of noise reduction. Specifically applied to the muffler of the vehicle, because the engine will generate a certain amount of noise when it is working, the noise it generates needs to be discharged after being processed by the muffler at the tail of the exhaust pipe. [0003] When the engine is at low speed or idling, the noise of the engine itself is small, and the exhaust noise is relatively prominent at this time. At this time, a relatively complicated tuning structure needs to be...
