  • 詳細介紹

汽車渦輪增壓器接頭

汽車要跑(pao)得快,就必須要有(you)強勁的(de)(de)動(dong)力。目前(qian)汽車的(de)(de)動(dong)力系統(tong)可粗分為(wei)(wei)自(zi)然(ran)(ran)(ran)進(jin)氣系統(tong)及增(zeng)(zeng)壓(ya)(ya)進(jin)氣系統(tong)兩大類。在(zai)歐洲跑(pao)車中,除(chu)了(le)寶馬汽車公(gong)司依(yi)然(ran)(ran)(ran)堅持使用(yong)(yong)自(zi)然(ran)(ran)(ran)進(jin)氣發動(dong)機外(wai),其他各汽車公(gong)司為(wei)(wei)了(le)提升車輛的(de)(de)動(dong)力性能,紛紛采用(yong)(yong)增(zeng)(zeng)壓(ya)(ya)系統(tong),例(li)如(ru):奔馳跑(pao)車使用(yong)(yong)機械(xie)增(zeng)(zeng)壓(ya)(ya)系統(tong),紳寶汽車則為(wei)(wei)渦(wo)輪(lun)增(zeng)(zeng)壓(ya)(ya)的(de)(de)開山鼻祖。近年日系汽車也開始大量采用(yong)(yong)渦(wo)輪(lun)增(zeng)(zeng)壓(ya)(ya)技術。自(zi)然(ran)(ran)(ran)進(jin)氣系統(tong)沒有(you)安裝(zhuang)任何形(xing)式(shi)的(de)(de)增(zeng)(zeng)壓(ya)(ya)器,只是(shi)利(li)用(yong)(yong)活塞(sai)下行所產生的(de)(de)負(fu)壓(ya)(ya)來吸進(jin)混(hun)合氣。雖(sui)然(ran)(ran)(ran)自(zi)然(ran)(ran)(ran)進(jin)氣系統(tong)通過可變氣門(men)正時系統(tong)能夠得到較大的(de)(de)馬力輸(shu)出,但動(dong)力的(de)(de)提升很(hen)有(you)限(xian)。為(wei)(wei)了(le)有(you)效增(zeng)(zeng)加發動(dong)機的(de)(de)輸(shu)出功(gong)率,采用(yong)(yong)增(zeng)(zeng)壓(ya)(ya)系統(tong)可說是(shi)最有(you)效的(de)(de)方式(shi)。

最(zui)常見的(de)發動(dong)機增壓系(xi)統有機械增壓與廢(fei)氣渦輪增壓兩種。

機械增(zeng)壓

發動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)以(yi)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)方(fang)式(shi)驅(qu)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)進行增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya),稱為機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)。當發動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)采用機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)時(shi),通(tong)常(chang)由(you)發動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)曲(qu)軸(zhou)通(tong)過齒輪(lun)(lun)驅(qu)動(dong)(dong)(dong)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)。增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)一般(ban)采用離心式(shi)或羅茨壓(ya)(ya)(ya)(ya)氣(qi)機(ji)(ji)(ji)(ji)(ji),個(ge)別的(de)(de)(de)(de)采用螺(luo)桿(gan)式(shi)壓(ya)(ya)(ya)(ya)氣(qi)機(ji)(ji)(ji)(ji)(ji)。近(jin)年來,在國外(wai)也開始采用新型的(de)(de)(de)(de)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)渦(wo)旋式(shi)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)。因為驅(qu)動(dong)(dong)(dong)壓(ya)(ya)(ya)(ya)氣(qi)機(ji)(ji)(ji)(ji)(ji)消(xiao)耗(hao)了發動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)一定(ding)的(de)(de)(de)(de)輸出功率(lv)(lv),所(suo)以(yi)機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)發動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)熱效(xiao)率(lv)(lv)不一定(ding)得到(dao)(dao)改善,有(you)時(shi)反而(er)比非增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)內(nei)燃(ran)機(ji)(ji)(ji)(ji)(ji)還低些。選擇(ze)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)力時(shi),首先(xian)要保證能(neng)達到(dao)(dao)所(suo)要求(qiu)的(de)(de)(de)(de)平均有(you)效(xiao)壓(ya)(ya)(ya)(ya)力,其次要獲得盡(jin)可(ke)能(neng)低的(de)(de)(de)(de)燃(ran)油消(xiao)耗(hao)率(lv)(lv)。擔這兩個(ge)要求(qiu)對(dui)于機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)來說常(chang)常(chang)是相互矛盾的(de)(de)(de)(de)。如(ru)果追求(qiu)平均有(you)效(xiao)壓(ya)(ya)(ya)(ya)力,則必然(ran)導致機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)效(xiao)率(lv)(lv)降低,燃(ran)油消(xiao)耗(hao)率(lv)(lv)升高。因此(ci),增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)力值的(de)(de)(de)(de)選取應在功率(lv)(lv)和燃(ran)油消(xiao)耗(hao)率(lv)(lv)兩者之間尋求(qiu)最佳的(de)(de)(de)(de)妥協方(fang)案。機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)系統目前(qian)在歐洲車上用得較普(pu)遍(bian)。由(you)于機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)的(de)(de)(de)(de)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)(ji)是在曲(qu)軸(zhou)的(de)(de)(de)(de)帶(dai)動(dong)(dong)(dong)下持續(xu)(xu)地運轉,因此(ci)不動(dong)(dong)(dong)產生像渦(wo)輪(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)的(de)(de)(de)(de)渦(wo)輪(lun)(lun)遲滯現象。機(ji)(ji)(ji)(ji)(ji)械(xie)(xie)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)雖然(ran)只(zhi)能(neng)提升約10%20%的(de)(de)(de)(de)動(dong)(dong)(dong)力輸出,但平順連續(xu)(xu)性是渦(wo)輪(lun)(lun)增(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)發動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)所(suo)不及的(de)(de)(de)(de)。

廢氣(qi)渦輪增(zeng)壓

利(li)用(yong)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)能量(liang)(liang)驅動(dong)(dong)(dong)(dong)(dong)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi),稱為廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(簡稱渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)),如圖所示是(shi)廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)系統。廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)特(te)點是(shi)在渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi)和(he)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)之間(jian)沒(mei)有機(ji)(ji)械連接。它們(men)之間(jian)靠氣(qi)(qi)(qi)路相通。因(yin)為壓(ya)(ya)(ya)(ya)(ya)氣(qi)(qi)(qi)機(ji)(ji)消(xiao)耗的(de)(de)(de)功是(shi)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)從廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)中回收(shou)的(de)(de)(de)一(yi)部分能量(liang)(liang),所以(yi)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)不僅可以(yi)增(zeng)(zeng)加(jia)(jia)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)功率(lv),而且可以(yi)提(ti)高其熱效率(lv),降低燃(ran)油(you)消(xiao)耗率(lv)。如果在轎車尾(wei)部看到Turbo或(huo)者T的(de)(de)(de)標識,即(ji)表明該車采用(yong)的(de)(de)(de)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)是(shi)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)。渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)器(qi)實際上是(shi)臺空(kong)(kong)氣(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)機(ji)(ji),它是(shi)利(li)用(yong)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)排出的(de)(de)(de)廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)慣性推動(dong)(dong)(dong)(dong)(dong)渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun),渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)又(you)帶動(dong)(dong)(dong)(dong)(dong)同(tong)軸的(de)(de)(de)葉輪(lun)(lun)(lun)(lun)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)由空(kong)(kong)氣(qi)(qi)(qi)濾清器(qi)管道(dao)送(song)來的(de)(de)(de)空(kong)(kong)氣(qi)(qi)(qi),使空(kong)(kong)氣(qi)(qi)(qi)增(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)后進(jin)入氣(qi)(qi)(qi)缸。當發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)轉(zhuan)速提(ti)高,廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)排出速度與渦(wo)(wo)(wo)輪(lun)(lun)(lun)(lun)轉(zhuan)速也(ye)同(tong)步提(ti)高,葉輪(lun)(lun)(lun)(lun)就(jiu)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)(suo)更多(duo)的(de)(de)(de)空(kong)(kong)氣(qi)(qi)(qi)進(jin)入氣(qi)(qi)(qi)缸,空(kong)(kong)氣(qi)(qi)(qi)的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)和(he)密(mi)度增(zeng)(zeng)大可以(yi)燃(ran)燒(shao)更多(duo)的(de)(de)(de)燃(ran)油(you),相應增(zeng)(zeng)加(jia)(jia)油(you)量(liang)(liang)和(he)調整一(yi)下(xia)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)轉(zhuan)速,就(jiu)可以(yi)增(zeng)(zeng)加(jia)(jia)發(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)輸(shu)出功率(lv)。
