style="text-indent:25px">摩托車消聲器是摩托車發(fā)展史上不可或缺的零部件，摩托車消聲器發(fā)展歷史也與摩托車一樣久遠。發(fā)動機在做功后，緊接著是排氣沖程。排氣是將氣缸內的廢氣排出。由于這時的廢氣是高溫高壓，由排氣管直接排出，將是很大的噪音。而消音器的作用簡單的說，就是發(fā)動機排出的氣流在消音器內經(jīng)過多孔的管子與隔板并反復的回繞后，噪音逐漸衰減，達到消音的目的。消聲器是一個多級分流分壓的組合體。其工作原理大致如下：進氣：此時進氣門打開，活塞下行，汽油和空氣的混合氣被吸進汽缸內 .壓縮：此時進氣門和排氣門同時關閉，活塞上行，混合氣被壓縮。燃燒：當混合氣被壓縮到較小時火花塞跳火點燃混合氣，燃燒產生的壓力推動活塞下行并帶動曲軸旋轉。排氣：當活塞下行到較低點時排氣門打開，廢氣排出，活塞繼續(xù)上行把多余的廢氣排出。小孔消聲器的結構是一根末端封閉的直管，管壁上鉆有很多小孔。潮州消聲器廠家</p><p style="text-indent:25px">阻性式消聲器：主要是利用多孔吸聲材料來降低噪聲的。潮州消聲器廠家</p><p style="text-indent:25px">直管消聲器消聲量的計算:直管式消聲器消聲量主要與通道形式、長度和吸聲材料的性能有關。消聲量的計算公式為：其中，Φ是消聲系數(shù)，即每米消聲量(dB/m)；P是消聲器通道截面周長(m)；S是消聲器通道截面積(m2)。消聲管道內吸聲系數(shù)越大，消聲系數(shù)Φ越大，消聲量越高。增加長度，或增加通道周長與截面積的比P/S，消聲量越大。同樣周長，圓形截面的周長與截面積的比，要比扁狀的矩形小很多，因此，圓形截面的直管式消聲器消聲性能小。當直管消聲器截面較大時，如徑尺寸大于30cm的圓管或矩形管，高頻聲波成上束狀，將直接穿過管道，而與管壁的吸聲材料不發(fā)生作用，消聲性能變差，這種高頻性能下降的現(xiàn)象被稱為“高頻失效”。并將高頻消聲量明顯下降的頻率稱為“上限失效頻率”。潮州消聲器廠家</p><p
