  • 詳細介紹

汽車渦輪增壓器接頭

汽(qi)車要跑得快(kuai),就(jiu)必(bi)須要有(you)強(qiang)勁的(de)動(dong)(dong)(dong)力(li)(li)。目前汽(qi)車的(de)動(dong)(dong)(dong)力(li)(li)系(xi)統(tong)可粗分為(wei)自然(ran)(ran)(ran)進(jin)氣(qi)系(xi)統(tong)及增壓(ya)(ya)進(jin)氣(qi)系(xi)統(tong)兩大(da)(da)類。在歐洲跑車中(zhong),除(chu)了寶馬(ma)汽(qi)車公司依然(ran)(ran)(ran)堅持使(shi)用自然(ran)(ran)(ran)進(jin)氣(qi)發(fa)動(dong)(dong)(dong)機(ji)外,其他各(ge)汽(qi)車公司為(wei)了提(ti)升車輛的(de)動(dong)(dong)(dong)力(li)(li)性(xing)能,紛紛采(cai)(cai)用增壓(ya)(ya)系(xi)統(tong),例如:奔(ben)馳跑車使(shi)用機(ji)械增壓(ya)(ya)系(xi)統(tong),紳(shen)寶汽(qi)車則為(wei)渦(wo)輪增壓(ya)(ya)的(de)開(kai)山鼻祖(zu)。近年日系(xi)汽(qi)車也開(kai)始(shi)大(da)(da)量采(cai)(cai)用渦(wo)輪增壓(ya)(ya)技術(shu)。自然(ran)(ran)(ran)進(jin)氣(qi)系(xi)統(tong)沒有(you)安(an)裝(zhuang)任何形式的(de)增壓(ya)(ya)器(qi),只是(shi)利用活塞下行(xing)所產生(sheng)的(de)負壓(ya)(ya)來吸進(jin)混(hun)合氣(qi)。雖然(ran)(ran)(ran)自然(ran)(ran)(ran)進(jin)氣(qi)系(xi)統(tong)通過可變氣(qi)門正時系(xi)統(tong)能夠(gou)得到較大(da)(da)的(de)馬(ma)力(li)(li)輸(shu)出(chu),但動(dong)(dong)(dong)力(li)(li)的(de)提(ti)升很有(you)限。為(wei)了有(you)效(xiao)增加(jia)發(fa)動(dong)(dong)(dong)機(ji)的(de)輸(shu)出(chu)功(gong)率,采(cai)(cai)用增壓(ya)(ya)系(xi)統(tong)可說是(shi)最有(you)效(xiao)的(de)方式。

最(zui)常見的發動機增(zeng)壓系統(tong)有機械增(zeng)壓與(yu)廢氣(qi)渦輪增(zeng)壓兩種。

機械增壓

發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)以機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)方(fang)式(shi)驅動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)進行增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya),稱(cheng)為機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)。當發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)采(cai)用機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)時,通常由(you)發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)曲(qu)軸通過齒輪(lun)驅動(dong)(dong)(dong)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)。增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)一般采(cai)用離心式(shi)或羅茨壓(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)(ji),個(ge)別的(de)(de)采(cai)用螺桿(gan)式(shi)壓(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)(ji)。近年(nian)來,在(zai)(zai)國外也開始采(cai)用新型的(de)(de)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)渦(wo)旋式(shi)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi)(qi)。因(yin)為驅動(dong)(dong)(dong)壓(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)(ji)消(xiao)(xiao)耗了發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)一定(ding)的(de)(de)輸(shu)出功率,所以機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)的(de)(de)熱效率不一定(ding)得(de)(de)到改善,有(you)時反(fan)而比非增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)內燃機(ji)(ji)(ji)(ji)(ji)還低(di)些。選擇(ze)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)時,首先(xian)要保證能(neng)達(da)到所要求(qiu)的(de)(de)平均有(you)效壓(ya)(ya)(ya)(ya)(ya)力(li)(li),其(qi)次(ci)要獲得(de)(de)盡(jin)可(ke)能(neng)低(di)的(de)(de)燃油(you)消(xiao)(xiao)耗率。擔這兩個(ge)要求(qiu)對于(yu)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)來說常常是相(xiang)互(hu)矛盾的(de)(de)。如(ru)果追求(qiu)平均有(you)效壓(ya)(ya)(ya)(ya)(ya)力(li)(li),則必然(ran)導(dao)致機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)效率降(jiang)低(di),燃油(you)消(xiao)(xiao)耗率升(sheng)高。因(yin)此,增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)值的(de)(de)選取應在(zai)(zai)功率和(he)燃油(you)消(xiao)(xiao)耗率兩者之間尋求(qiu)最(zui)佳的(de)(de)妥協方(fang)案。機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)系統目(mu)前在(zai)(zai)歐洲車上用得(de)(de)較普遍。由(you)于(yu)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)(ji)是在(zai)(zai)曲(qu)軸的(de)(de)帶動(dong)(dong)(dong)下持(chi)續地運(yun)轉,因(yin)此不動(dong)(dong)(dong)產生(sheng)像(xiang)渦(wo)輪(lun)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)渦(wo)輪(lun)遲滯(zhi)現象。機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)雖然(ran)只能(neng)提升(sheng)約(yue)10%20%的(de)(de)動(dong)(dong)(dong)力(li)(li)輸(shu)出,但平順連續性是渦(wo)輪(lun)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)發(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)所不及(ji)的(de)(de)。

廢氣渦輪(lun)增(zeng)壓(ya)

利(li)用發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)能(neng)量驅動(dong)(dong)(dong)(dong)渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)器,稱為廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(簡稱渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)),如(ru)圖所(suo)示是廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)系(xi)統(tong)。廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)的(de)(de)(de)特(te)點是在渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)器和(he)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)之間沒(mei)有機(ji)(ji)(ji)械連接。它們之間靠氣(qi)(qi)(qi)(qi)路(lu)相(xiang)通。因(yin)為壓(ya)(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)機(ji)(ji)(ji)消耗的(de)(de)(de)功(gong)是渦(wo)(wo)(wo)輪(lun)(lun)從(cong)廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)中回收的(de)(de)(de)一(yi)部分(fen)能(neng)量,所(suo)以渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)不僅可以增(zeng)(zeng)加(jia)(jia)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)功(gong)率(lv),而且可以提高其(qi)熱(re)效率(lv),降低燃(ran)油(you)消耗率(lv)。如(ru)果在轎車尾部看到Turbo或者T的(de)(de)(de)標識,即表明該(gai)車采(cai)用的(de)(de)(de)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)是渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)的(de)(de)(de)。渦(wo)(wo)(wo)輪(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)器實際上是臺空氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)縮機(ji)(ji)(ji),它是利(li)用發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)排出(chu)的(de)(de)(de)廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)慣性推動(dong)(dong)(dong)(dong)渦(wo)(wo)(wo)輪(lun)(lun),渦(wo)(wo)(wo)輪(lun)(lun)又帶動(dong)(dong)(dong)(dong)同軸的(de)(de)(de)葉輪(lun)(lun)壓(ya)(ya)(ya)(ya)縮由空氣(qi)(qi)(qi)(qi)濾清器管道(dao)送(song)來的(de)(de)(de)空氣(qi)(qi)(qi)(qi),使空氣(qi)(qi)(qi)(qi)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)后進入氣(qi)(qi)(qi)(qi)缸。當發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)轉(zhuan)速(su)(su)提高,廢(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)排出(chu)速(su)(su)度(du)與渦(wo)(wo)(wo)輪(lun)(lun)轉(zhuan)速(su)(su)也(ye)同步提高,葉輪(lun)(lun)就壓(ya)(ya)(ya)(ya)縮更多的(de)(de)(de)空氣(qi)(qi)(qi)(qi)進入氣(qi)(qi)(qi)(qi)缸,空氣(qi)(qi)(qi)(qi)的(de)(de)(de)壓(ya)(ya)(ya)(ya)力和(he)密度(du)增(zeng)(zeng)大可以燃(ran)燒更多的(de)(de)(de)燃(ran)油(you),相(xiang)應增(zeng)(zeng)加(jia)(jia)油(you)量和(he)調整一(yi)下發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)轉(zhuan)速(su)(su),就可以增(zeng)(zeng)加(jia)(jia)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)輸出(chu)功(gong)率(lv)。
