  • 詳細介紹

汽車渦輪增壓器接頭

汽(qi)車(che)要(yao)跑(pao)得快,就必須要(yao)有強勁的(de)(de)動力。目前汽(qi)車(che)的(de)(de)動力系統可(ke)(ke)粗分為(wei)自然(ran)進(jin)(jin)(jin)氣(qi)(qi)系統及增(zeng)壓(ya)進(jin)(jin)(jin)氣(qi)(qi)系統兩大類。在歐洲跑(pao)車(che)中,除了寶馬(ma)汽(qi)車(che)公(gong)司依然(ran)堅持使用(yong)自然(ran)進(jin)(jin)(jin)氣(qi)(qi)發(fa)動機(ji)外,其他各汽(qi)車(che)公(gong)司為(wei)了提升車(che)輛的(de)(de)動力性能,紛紛采(cai)用(yong)增(zeng)壓(ya)系統,例(li)如:奔馳(chi)跑(pao)車(che)使用(yong)機(ji)械增(zeng)壓(ya)系統,紳寶汽(qi)車(che)則為(wei)渦(wo)輪增(zeng)壓(ya)的(de)(de)開山鼻(bi)祖。近(jin)年日系汽(qi)車(che)也開始大量(liang)采(cai)用(yong)渦(wo)輪增(zeng)壓(ya)技(ji)術。自然(ran)進(jin)(jin)(jin)氣(qi)(qi)系統沒有安裝(zhuang)任何(he)形式(shi)(shi)的(de)(de)增(zeng)壓(ya)器(qi),只是利用(yong)活塞下行所產生(sheng)的(de)(de)負壓(ya)來吸(xi)進(jin)(jin)(jin)混合氣(qi)(qi)。雖然(ran)自然(ran)進(jin)(jin)(jin)氣(qi)(qi)系統通過可(ke)(ke)變氣(qi)(qi)門正時系統能夠(gou)得到較大的(de)(de)馬(ma)力輸(shu)出,但動力的(de)(de)提升很(hen)有限。為(wei)了有效(xiao)增(zeng)加發(fa)動機(ji)的(de)(de)輸(shu)出功率,采(cai)用(yong)增(zeng)壓(ya)系統可(ke)(ke)說是最有效(xiao)的(de)(de)方(fang)式(shi)(shi)。

最常(chang)見的(de)發動機增(zeng)(zeng)壓系統有機械增(zeng)(zeng)壓與廢(fei)氣渦輪增(zeng)(zeng)壓兩種。

機械增壓(ya)

發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)以機(ji)(ji)(ji)(ji)械(xie)方式(shi)驅(qu)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)進(jin)行增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya),稱為機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)。當發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)采(cai)(cai)用機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)時,通(tong)常由(you)發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)曲軸通(tong)過齒輪驅(qu)動(dong)(dong)(dong)(dong)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)。增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)一般采(cai)(cai)用離心式(shi)或羅茨壓(ya)(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji),個別的采(cai)(cai)用螺桿式(shi)壓(ya)(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)。近年來,在國外也開始(shi)采(cai)(cai)用新型的機(ji)(ji)(ji)(ji)械(xie)渦旋式(shi)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)器(qi)。因(yin)(yin)為驅(qu)動(dong)(dong)(dong)(dong)壓(ya)(ya)(ya)(ya)(ya)(ya)氣機(ji)(ji)(ji)(ji)消(xiao)(xiao)耗(hao)(hao)了發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)一定的輸出功率,所以機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的熱效(xiao)率不(bu)一定得(de)到(dao)(dao)改善,有時反而比非增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)內燃機(ji)(ji)(ji)(ji)還(huan)低(di)些。選擇增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)(ya)力時,首先要保證(zheng)能達到(dao)(dao)所要求(qiu)的平(ping)均有效(xiao)壓(ya)(ya)(ya)(ya)(ya)(ya)力,其次要獲得(de)盡可(ke)能低(di)的燃油消(xiao)(xiao)耗(hao)(hao)率。擔這兩個要求(qiu)對于機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)來說常常是(shi)(shi)相互矛(mao)盾的。如果追求(qiu)平(ping)均有效(xiao)壓(ya)(ya)(ya)(ya)(ya)(ya)力,則必然導致(zhi)機(ji)(ji)(ji)(ji)械(xie)效(xiao)率降(jiang)低(di),燃油消(xiao)(xiao)耗(hao)(hao)率升高。因(yin)(yin)此,增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)(ya)(ya)力值的選取(qu)應在功率和(he)燃油消(xiao)(xiao)耗(hao)(hao)率兩者之間尋求(qiu)最佳(jia)的妥(tuo)協方案。機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)系(xi)統目前在歐(ou)洲(zhou)車(che)上用得(de)較普遍。由(you)于機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)的增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)機(ji)(ji)(ji)(ji)是(shi)(shi)在曲軸的帶動(dong)(dong)(dong)(dong)下持續(xu)(xu)地運轉,因(yin)(yin)此不(bu)動(dong)(dong)(dong)(dong)產生像渦輪增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)的渦輪遲滯現(xian)象。機(ji)(ji)(ji)(ji)械(xie)增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)雖(sui)然只(zhi)能提(ti)升約10%20%的動(dong)(dong)(dong)(dong)力輸出,但平(ping)順連續(xu)(xu)性是(shi)(shi)渦輪增(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)(ya)發(fa)(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)所不(bu)及的。

廢氣渦輪增壓

利用發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)能量驅動(dong)(dong)(dong)(dong)(dong)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)器,稱(cheng)為廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)(簡(jian)稱(cheng)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)),如(ru)圖所(suo)示是廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)系(xi)統。廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)的(de)(de)(de)(de)特點(dian)是在渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)器和發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)之間(jian)沒有(you)機(ji)(ji)(ji)械連接。它們之間(jian)靠氣(qi)(qi)(qi)(qi)(qi)路相通。因為壓(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)(qi)機(ji)(ji)(ji)消耗的(de)(de)(de)(de)功是渦(wo)(wo)輪(lun)(lun)(lun)從(cong)廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)回(hui)收(shou)的(de)(de)(de)(de)一(yi)部(bu)分能量,所(suo)以(yi)(yi)渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)不僅可以(yi)(yi)增(zeng)加(jia)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)(de)功率(lv),而(er)且可以(yi)(yi)提高其熱效率(lv),降低燃(ran)油(you)消耗率(lv)。如(ru)果在轎車尾部(bu)看到Turbo或者T的(de)(de)(de)(de)標識,即表明該車采(cai)用的(de)(de)(de)(de)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)是渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)的(de)(de)(de)(de)。渦(wo)(wo)輪(lun)(lun)(lun)增(zeng)壓(ya)(ya)(ya)器實際(ji)上是臺空氣(qi)(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)縮機(ji)(ji)(ji),它是利用發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)排出(chu)(chu)的(de)(de)(de)(de)廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)慣性推動(dong)(dong)(dong)(dong)(dong)渦(wo)(wo)輪(lun)(lun)(lun),渦(wo)(wo)輪(lun)(lun)(lun)又帶動(dong)(dong)(dong)(dong)(dong)同軸的(de)(de)(de)(de)葉輪(lun)(lun)(lun)壓(ya)(ya)(ya)縮由空氣(qi)(qi)(qi)(qi)(qi)濾清器管道送(song)來的(de)(de)(de)(de)空氣(qi)(qi)(qi)(qi)(qi),使空氣(qi)(qi)(qi)(qi)(qi)增(zeng)壓(ya)(ya)(ya)后進入(ru)氣(qi)(qi)(qi)(qi)(qi)缸(gang)。當發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)轉(zhuan)速提高,廢(fei)(fei)氣(qi)(qi)(qi)(qi)(qi)排出(chu)(chu)速度與渦(wo)(wo)輪(lun)(lun)(lun)轉(zhuan)速也同步提高,葉輪(lun)(lun)(lun)就壓(ya)(ya)(ya)縮更(geng)多(duo)的(de)(de)(de)(de)空氣(qi)(qi)(qi)(qi)(qi)進入(ru)氣(qi)(qi)(qi)(qi)(qi)缸(gang),空氣(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)壓(ya)(ya)(ya)力和密(mi)度增(zeng)大可以(yi)(yi)燃(ran)燒更(geng)多(duo)的(de)(de)(de)(de)燃(ran)油(you),相應增(zeng)加(jia)油(you)量和調整(zheng)一(yi)下發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)(de)轉(zhuan)速,就可以(yi)(yi)增(zeng)加(jia)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)(de)輸出(chu)(chu)功率(lv)。
