求翻譯:In a free exhaust phase, exhaust valve at the speed of the airflow due to a strong jet and jet noise. Also, because the gas viscosity, gas emissions will drive along the gas exhaust valve movement after entrainment, so that the surrounding gas is rotated, the formation of eddy current, eddy current radiated noise.

在自由排氣階段,排氣閥門由于強烈的噴氣機和噴氣噪聲的氣流速度。此外,由于氣體的粘度,氣體排放量將帶動沿線尾氣閥動作后夾帶,使周圍的氣體旋轉(zhuǎn),形成渦流,渦流的輻射噪聲。此外,廢氣壓力存在附近的不連續(xù)性。這種壓力會產(chǎn)生沖擊波是不連續(xù)的的,產(chǎn)生脈沖噪聲。

在自由排氣階段,排氣閥的強勁的噴射氣流速度和噴氣噪聲。此外,因為氣體粘度、 氣體排放會駕駛沿氣體排放閥運動后夾帶,使周圍的氣體旋轉(zhuǎn),形成渦流的渦流當前輻射的噪聲。此外,排放氣體的壓力存在近不連續(xù)性。這種壓力會產(chǎn)生激波不是連續(xù)的產(chǎn)生脈沖噪聲環(huán)境中。
