汽車渦輪增壓器接頭

汽(qi)車(che)(che)(che)(che)要跑(pao)得快(kuai),就必須(xu)要有強(qiang)勁的(de)(de)(de)動(dong)力(li)。目前(qian)汽(qi)車(che)(che)(che)(che)的(de)(de)(de)動(dong)力(li)系(xi)統(tong)(tong)(tong)可(ke)粗分(fen)為(wei)自(zi)(zi)然(ran)進氣(qi)系(xi)統(tong)(tong)(tong)及(ji)增(zeng)(zeng)(zeng)壓(ya)進氣(qi)系(xi)統(tong)(tong)(tong)兩(liang)大類(lei)。在(zai)歐洲跑(pao)車(che)(che)(che)(che)中,除了(le)寶(bao)馬汽(qi)車(che)(che)(che)(che)公司(si)(si)依然(ran)堅持使(shi)用自(zi)(zi)然(ran)進氣(qi)發動(dong)機外(wai),其(qi)他各汽(qi)車(che)(che)(che)(che)公司(si)(si)為(wei)了(le)提升車(che)(che)(che)(che)輛的(de)(de)(de)動(dong)力(li)性能(neng),紛紛采用增(zeng)(zeng)(zeng)壓(ya)系(xi)統(tong)(tong)(tong),例如:奔馳跑(pao)車(che)(che)(che)(che)使(shi)用機械增(zeng)(zeng)(zeng)壓(ya)系(xi)統(tong)(tong)(tong),紳寶(bao)汽(qi)車(che)(che)(che)(che)則為(wei)渦輪增(zeng)(zeng)(zeng)壓(ya)的(de)(de)(de)開(kai)山鼻祖。近年(nian)日系(xi)汽(qi)車(che)(che)(che)(che)也開(kai)始大量采用渦輪增(zeng)(zeng)(zeng)壓(ya)技術。自(zi)(zi)然(ran)進氣(qi)系(xi)統(tong)(tong)(tong)沒有安裝(zhuang)任何形(xing)式的(de)(de)(de)增(zeng)(zeng)(zeng)壓(ya)器,只(zhi)是利用活塞下行(xing)所產生(sheng)的(de)(de)(de)負壓(ya)來吸(xi)進混合氣(qi)。雖(sui)然(ran)自(zi)(zi)然(ran)進氣(qi)系(xi)統(tong)(tong)(tong)通過可(ke)變氣(qi)門正時系(xi)統(tong)(tong)(tong)能(neng)夠得到較大的(de)(de)(de)馬力(li)輸出,但動(dong)力(li)的(de)(de)(de)提升很有限。為(wei)了(le)有效增(zeng)(zeng)(zeng)加發動(dong)機的(de)(de)(de)輸出功率,采用增(zeng)(zeng)(zeng)壓(ya)系(xi)統(tong)(tong)(tong)可(ke)說是最有效的(de)(de)(de)方式。

最常見(jian)的發動機(ji)增(zeng)壓系統(tong)有機(ji)械增(zeng)壓與廢(fei)氣(qi)渦輪增(zeng)壓兩種。

機(ji)械增壓

發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)以機(ji)(ji)(ji)(ji)械(xie)(xie)方(fang)式(shi)驅(qu)(qu)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器進行增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya),稱(cheng)為機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)。當發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)采(cai)用(yong)(yong)機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)時,通常由發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)曲(qu)軸(zhou)通過齒輪驅(qu)(qu)動(dong)(dong)(dong)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器。增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器一(yi)般采(cai)用(yong)(yong)離心式(shi)或(huo)羅茨壓(ya)(ya)(ya)(ya)(ya)(ya)氣(qi)機(ji)(ji)(ji)(ji),個(ge)別的(de)(de)(de)(de)(de)采(cai)用(yong)(yong)螺桿(gan)式(shi)壓(ya)(ya)(ya)(ya)(ya)(ya)氣(qi)機(ji)(ji)(ji)(ji)。近年來,在國外也開始(shi)采(cai)用(yong)(yong)新型(xing)的(de)(de)(de)(de)(de)機(ji)(ji)(ji)(ji)械(xie)(xie)渦(wo)旋式(shi)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器。因(yin)為驅(qu)(qu)動(dong)(dong)(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)氣(qi)機(ji)(ji)(ji)(ji)消(xiao)耗(hao)了發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)一(yi)定(ding)的(de)(de)(de)(de)(de)輸出(chu)功率(lv),所以機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)熱效(xiao)率(lv)不(bu)一(yi)定(ding)得到改善,有(you)時反而比(bi)非增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)內燃(ran)(ran)機(ji)(ji)(ji)(ji)還(huan)低(di)(di)些。選擇增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)時,首先要保(bao)證能(neng)(neng)達到所要求(qiu)(qiu)的(de)(de)(de)(de)(de)平均(jun)有(you)效(xiao)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li),其(qi)次要獲(huo)得盡可能(neng)(neng)低(di)(di)的(de)(de)(de)(de)(de)燃(ran)(ran)油消(xiao)耗(hao)率(lv)。擔這兩個(ge)要求(qiu)(qiu)對于機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)來說常常是相(xiang)互矛盾的(de)(de)(de)(de)(de)。如果追求(qiu)(qiu)平均(jun)有(you)效(xiao)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li),則必然(ran)導致(zhi)機(ji)(ji)(ji)(ji)械(xie)(xie)效(xiao)率(lv)降低(di)(di),燃(ran)(ran)油消(xiao)耗(hao)率(lv)升高(gao)。因(yin)此,增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)值的(de)(de)(de)(de)(de)選取應在功率(lv)和(he)燃(ran)(ran)油消(xiao)耗(hao)率(lv)兩者之間(jian)尋求(qiu)(qiu)最佳(jia)的(de)(de)(de)(de)(de)妥協方(fang)案(an)。機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)系統目前在歐洲車上用(yong)(yong)得較普遍(bian)。由于機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)(de)(de)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)是在曲(qu)軸(zhou)的(de)(de)(de)(de)(de)帶動(dong)(dong)(dong)下持續(xu)地運轉,因(yin)此不(bu)動(dong)(dong)(dong)產生(sheng)像(xiang)渦(wo)輪增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)(de)(de)渦(wo)輪遲(chi)滯現象。機(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)雖然(ran)只能(neng)(neng)提升約10%20%的(de)(de)(de)(de)(de)動(dong)(dong)(dong)力(li)(li)輸出(chu),但平順連續(xu)性是渦(wo)輪增(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)所不(bu)及的(de)(de)(de)(de)(de)。

廢氣渦輪增壓(ya)

利(li)用發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)能量(liang)驅動(dong)(dong)(dong)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)器(qi),稱(cheng)為廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)(簡稱(cheng)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)),如圖所示是(shi)(shi)廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)系統。廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)的(de)(de)(de)特點是(shi)(shi)在渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)器(qi)和(he)(he)(he)發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)之(zhi)間沒有機(ji)(ji)械連接。它(ta)們之(zhi)間靠(kao)氣(qi)(qi)(qi)(qi)(qi)路相通。因為壓(ya)(ya)氣(qi)(qi)(qi)(qi)(qi)機(ji)(ji)消(xiao)耗的(de)(de)(de)功是(shi)(shi)渦(wo)(wo)輪(lun)(lun)(lun)從廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)回收的(de)(de)(de)一(yi)部(bu)分(fen)能量(liang),所以(yi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)不僅(jin)可(ke)以(yi)增(zeng)(zeng)(zeng)加(jia)(jia)發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)功率,而且可(ke)以(yi)提高(gao)其熱效(xiao)率,降低燃油(you)消(xiao)耗率。如果在轎車尾(wei)部(bu)看到(dao)Turbo或者T的(de)(de)(de)標識(shi),即(ji)表(biao)明(ming)該(gai)車采用的(de)(de)(de)發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)是(shi)(shi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)的(de)(de)(de)。渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)器(qi)實際上(shang)是(shi)(shi)臺(tai)空(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)縮機(ji)(ji),它(ta)是(shi)(shi)利(li)用發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)排出的(de)(de)(de)廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)慣性推動(dong)(dong)(dong)渦(wo)(wo)輪(lun)(lun)(lun),渦(wo)(wo)輪(lun)(lun)(lun)又(you)帶動(dong)(dong)(dong)同軸的(de)(de)(de)葉輪(lun)(lun)(lun)壓(ya)(ya)縮由空(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)濾清器(qi)管道送來的(de)(de)(de)空(kong)(kong)氣(qi)(qi)(qi)(qi)(qi),使空(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)增(zeng)(zeng)(zeng)壓(ya)(ya)后進入氣(qi)(qi)(qi)(qi)(qi)缸。當發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)轉(zhuan)速(su)(su)提高(gao),廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)排出速(su)(su)度(du)與渦(wo)(wo)輪(lun)(lun)(lun)轉(zhuan)速(su)(su)也同步(bu)提高(gao),葉輪(lun)(lun)(lun)就(jiu)壓(ya)(ya)縮更多的(de)(de)(de)空(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)進入氣(qi)(qi)(qi)(qi)(qi)缸,空(kong)(kong)氣(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)壓(ya)(ya)力和(he)(he)(he)密度(du)增(zeng)(zeng)(zeng)大可(ke)以(yi)燃燒(shao)更多的(de)(de)(de)燃油(you),相應(ying)增(zeng)(zeng)(zeng)加(jia)(jia)油(you)量(liang)和(he)(he)(he)調整一(yi)下發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)轉(zhuan)速(su)(su),就(jiu)可(ke)以(yi)增(zeng)(zeng)(zeng)加(jia)(jia)發(fa)(fa)(fa)(fa)動(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)輸出功率。
