gas exhaust manifold 中文意思是什麼
gas exhaust manifold
解釋
排氣歧管-
The exhaust gas exits through the other exhaust manifold.
廢氣經另外一個排氣歧管排出。 -
The exhaust gas spews out of the exhaust valve and enters into the muffler along the exhaust manifold before draining into the atmosphere from the tail pipe. this process yields wide band exhaust noise
發動機廢氣從排氣門高速沖出，沿著排氣歧管進入消聲器，最後從尾管排入大氣，在這一過程中產生了寬頻帶的排氣噪聲。 -
The exhaust noise contains complex noise elements, including the exhaust noise with a base frequency measured in the number of exhausts in unit time, the resonance noise of the gas column in the pipe, the gas stream blowing noise at the exhaust manifold, the exhaust gas jetting and impact noise, the helmholtz resonance noise of the cylinder, the karman eddy noise and the turbulent noise inside the exhaust system
排氣噪聲包含了復雜的噪聲成分：以單位時間內排氣次數為基頻的排氣噪聲、管道內氣柱共振噪聲、排氣歧管處的氣流吹氣噪聲、廢氣噴注和沖擊噪聲、汽缸的亥姆霍茲共振噪聲、卡門渦流噪聲及排氣系統內部的湍流噪聲等。 -
When volume efficiency is computed by an engine cycle simulation considering gas flow in intake and exhaust manifold as one - dimensional unsteady flow, improperly given parameters in the simulation may cause an error over 5 %
摘要採用進排氣管流動為一維非定常模型的發動機循環模擬方法計算充氣效率時，若模型中給定的參數不合適，可能引起充氣效率的計算誤差超過5 % 。
