  • 詳細介紹

汽車渦輪增壓器接頭

汽(qi)(qi)車(che)(che)(che)要跑(pao)得(de)快,就必須要有(you)強(qiang)勁的動(dong)力。目前汽(qi)(qi)車(che)(che)(che)的動(dong)力系統(tong)(tong)(tong)可粗(cu)分為自然(ran)進(jin)氣系統(tong)(tong)(tong)及增壓(ya)(ya)進(jin)氣系統(tong)(tong)(tong)兩大類。在歐洲(zhou)跑(pao)車(che)(che)(che)中,除(chu)了(le)寶馬(ma)汽(qi)(qi)車(che)(che)(che)公司依然(ran)堅持使(shi)(shi)用(yong)自然(ran)進(jin)氣發動(dong)機外,其他(ta)各汽(qi)(qi)車(che)(che)(che)公司為了(le)提升(sheng)車(che)(che)(che)輛的動(dong)力性能(neng),紛(fen)紛(fen)采(cai)(cai)用(yong)增壓(ya)(ya)系統(tong)(tong)(tong),例如:奔(ben)馳(chi)跑(pao)車(che)(che)(che)使(shi)(shi)用(yong)機械增壓(ya)(ya)系統(tong)(tong)(tong),紳寶汽(qi)(qi)車(che)(che)(che)則為渦輪(lun)增壓(ya)(ya)的開山鼻祖(zu)。近年日系汽(qi)(qi)車(che)(che)(che)也開始大量采(cai)(cai)用(yong)渦輪(lun)增壓(ya)(ya)技術。自然(ran)進(jin)氣系統(tong)(tong)(tong)沒有(you)安(an)裝任何形式的增壓(ya)(ya)器,只(zhi)是(shi)利(li)用(yong)活塞下(xia)行所產生的負(fu)壓(ya)(ya)來吸進(jin)混合(he)氣。雖然(ran)自然(ran)進(jin)氣系統(tong)(tong)(tong)通過可變氣門正時系統(tong)(tong)(tong)能(neng)夠得(de)到較(jiao)大的馬(ma)力輸出,但動(dong)力的提升(sheng)很有(you)限。為了(le)有(you)效(xiao)(xiao)增加發動(dong)機的輸出功率,采(cai)(cai)用(yong)增壓(ya)(ya)系統(tong)(tong)(tong)可說是(shi)最有(you)效(xiao)(xiao)的方式。

最常見的發動(dong)機(ji)增壓系統有(you)機(ji)械增壓與廢氣渦輪增壓兩種。

機械增壓

發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)以(yi)機(ji)(ji)(ji)(ji)(ji)(ji)械方(fang)式(shi)驅(qu)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)進行增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya),稱為機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)。當發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)采(cai)(cai)用(yong)機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)時,通常(chang)由(you)發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)曲軸(zhou)通過齒輪(lun)(lun)驅(qu)動(dong)(dong)(dong)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)。增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)一(yi)般采(cai)(cai)用(yong)離心式(shi)或羅(luo)茨壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)(ji)(ji),個(ge)別的(de)(de)(de)(de)采(cai)(cai)用(yong)螺桿式(shi)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)(ji)(ji)。近年(nian)來,在(zai)(zai)國外(wai)也開始采(cai)(cai)用(yong)新型的(de)(de)(de)(de)機(ji)(ji)(ji)(ji)(ji)(ji)械渦(wo)旋式(shi)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)器(qi)。因(yin)為驅(qu)動(dong)(dong)(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)(ji)(ji)消耗(hao)了發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)一(yi)定的(de)(de)(de)(de)輸出功率(lv),所(suo)以(yi)機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)熱效(xiao)率(lv)不一(yi)定得(de)(de)到改善,有(you)時反而比非增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)內燃機(ji)(ji)(ji)(ji)(ji)(ji)還低些。選(xuan)擇(ze)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)力(li)時,首先要保證能(neng)(neng)達(da)到所(suo)要求(qiu)(qiu)的(de)(de)(de)(de)平(ping)均(jun)有(you)效(xiao)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)力(li),其次要獲(huo)得(de)(de)盡可能(neng)(neng)低的(de)(de)(de)(de)燃油消耗(hao)率(lv)。擔(dan)這兩個(ge)要求(qiu)(qiu)對(dui)于機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)來說常(chang)常(chang)是(shi)(shi)相互矛盾的(de)(de)(de)(de)。如果追求(qiu)(qiu)平(ping)均(jun)有(you)效(xiao)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)力(li),則必然導(dao)致機(ji)(ji)(ji)(ji)(ji)(ji)械效(xiao)率(lv)降(jiang)低,燃油消耗(hao)率(lv)升高(gao)。因(yin)此,增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)力(li)值(zhi)的(de)(de)(de)(de)選(xuan)取應在(zai)(zai)功率(lv)和燃油消耗(hao)率(lv)兩者之間尋求(qiu)(qiu)最佳的(de)(de)(de)(de)妥協方(fang)案。機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)系統目前(qian)在(zai)(zai)歐洲(zhou)車(che)上(shang)用(yong)得(de)(de)較(jiao)普遍。由(you)于機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)(de)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)(ji)(ji)是(shi)(shi)在(zai)(zai)曲軸(zhou)的(de)(de)(de)(de)帶動(dong)(dong)(dong)下持(chi)續地運轉(zhuan),因(yin)此不動(dong)(dong)(dong)產(chan)生(sheng)像渦(wo)輪(lun)(lun)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)(de)渦(wo)輪(lun)(lun)遲滯現象。機(ji)(ji)(ji)(ji)(ji)(ji)械增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)雖然只(zhi)能(neng)(neng)提(ti)升約10%20%的(de)(de)(de)(de)動(dong)(dong)(dong)力(li)輸出,但平(ping)順(shun)連續性是(shi)(shi)渦(wo)輪(lun)(lun)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)所(suo)不及的(de)(de)(de)(de)。

廢氣渦輪增壓

利用(yong)(yong)發(fa)動(dong)(dong)(dong)(dong)機(ji)廢(fei)(fei)(fei)氣(qi)(qi)能量驅動(dong)(dong)(dong)(dong)渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi),稱(cheng)為(wei)廢(fei)(fei)(fei)氣(qi)(qi)渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(簡稱(cheng)渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)),如(ru)圖所(suo)示(shi)是(shi)廢(fei)(fei)(fei)氣(qi)(qi)渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)系(xi)統(tong)。廢(fei)(fei)(fei)氣(qi)(qi)渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)的(de)(de)特點是(shi)在渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi)和(he)發(fa)動(dong)(dong)(dong)(dong)機(ji)之間沒有機(ji)械連接。它們之間靠氣(qi)(qi)路(lu)相(xiang)通(tong)。因(yin)為(wei)壓(ya)(ya)(ya)(ya)氣(qi)(qi)機(ji)消(xiao)耗的(de)(de)功(gong)是(shi)渦輪(lun)(lun)(lun)從廢(fei)(fei)(fei)氣(qi)(qi)中(zhong)回收(shou)的(de)(de)一部(bu)分能量,所(suo)以渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)發(fa)動(dong)(dong)(dong)(dong)機(ji)不僅可以增(zeng)(zeng)(zeng)(zeng)加發(fa)動(dong)(dong)(dong)(dong)機(ji)的(de)(de)功(gong)率(lv),而且可以提高(gao)其熱(re)效率(lv),降低燃油消(xiao)耗率(lv)。如(ru)果在轎車(che)尾部(bu)看(kan)到Turbo或者(zhe)T的(de)(de)標(biao)識,即表明該車(che)采用(yong)(yong)的(de)(de)發(fa)動(dong)(dong)(dong)(dong)機(ji)是(shi)渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)的(de)(de)。渦輪(lun)(lun)(lun)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)器(qi)實際上是(shi)臺(tai)空(kong)(kong)氣(qi)(qi)壓(ya)(ya)(ya)(ya)縮機(ji),它是(shi)利用(yong)(yong)發(fa)動(dong)(dong)(dong)(dong)機(ji)排(pai)出的(de)(de)廢(fei)(fei)(fei)氣(qi)(qi)慣性推動(dong)(dong)(dong)(dong)渦輪(lun)(lun)(lun),渦輪(lun)(lun)(lun)又(you)帶動(dong)(dong)(dong)(dong)同(tong)軸的(de)(de)葉(xie)輪(lun)(lun)(lun)壓(ya)(ya)(ya)(ya)縮由空(kong)(kong)氣(qi)(qi)濾清器(qi)管(guan)道送來的(de)(de)空(kong)(kong)氣(qi)(qi),使空(kong)(kong)氣(qi)(qi)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)后(hou)進入(ru)氣(qi)(qi)缸。當(dang)發(fa)動(dong)(dong)(dong)(dong)機(ji)轉(zhuan)速提高(gao),廢(fei)(fei)(fei)氣(qi)(qi)排(pai)出速度(du)與渦輪(lun)(lun)(lun)轉(zhuan)速也同(tong)步提高(gao),葉(xie)輪(lun)(lun)(lun)就壓(ya)(ya)(ya)(ya)縮更(geng)多(duo)的(de)(de)空(kong)(kong)氣(qi)(qi)進入(ru)氣(qi)(qi)缸,空(kong)(kong)氣(qi)(qi)的(de)(de)壓(ya)(ya)(ya)(ya)力和(he)密度(du)增(zeng)(zeng)(zeng)(zeng)大可以燃燒更(geng)多(duo)的(de)(de)燃油,相(xiang)應增(zeng)(zeng)(zeng)(zeng)加油量和(he)調(diao)整一下發(fa)動(dong)(dong)(dong)(dong)機(ji)的(de)(de)轉(zhuan)速,就可以增(zeng)(zeng)(zeng)(zeng)加發(fa)動(dong)(dong)(dong)(dong)機(ji)的(de)(de)輸(shu)出功(gong)率(lv)。
