發電機調節器簡介

汽車的供電(dian)(dian)(dian)系統是由汽車蓄電(dian)(dian)(dian)池和發(fa)(fa)電(dian)(dian)(dian)機組成，發(fa)(fa)電(dian)(dian)(dian)機負(fu)責對電(dian)(dian)(dian)池進行充電(dian)(dian)(dian)，使電(dian)(dian)(dian)池長期保(bao)持在足(zu)電(dian)(dian)(dian)狀態。電(dian)(dian)(dian)池和發(fa)(fa)電(dian)(dian)(dian)機負(fu)責對全車的電(dian)(dian)(dian)器進行供電(dian)(dian)(dian)。

電壓調節器的作用：在發電機轉速變化時，自動控制發電機電壓，使其保持恒定，防止發電機電壓過高而燒壞用電設備和導致蓄電池過量充電，同時也防止發電機電壓過低而導致用電設備工作失常和蓄電池充電不足。
電壓調節器的工作原理：由于發電機與發動機的傳動比固定，所以發電機的轉速將隨發動機轉速的變化而變化。汽車在運行過程中，發動機轉速變化范圍很大，發電機的端電壓也將隨發動機的轉速變化而在很大范圍內變化。發電機對用電設備供電和向蓄電池充電，都要求其電壓穩定，所以為使電壓始終保持在某一數值基本不變，就必須對發電機的輸出電壓進行調節。

發電機調節器的主要作用

發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)調節(jie)器的(de)主(zhu)要作用是(shi)為了(le)控制發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)額定值內，由于(yu)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)與發(fa)(fa)(fa)動機(ji)的(de)傳(chuan)動比是(shi)固(gu)定的(de)，所以發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)轉速將(jiang)隨(sui)發(fa)(fa)(fa)動機(ji)轉速的(de)變(bian)化(hua)而變(bian)化(hua)。汽(qi)車(che)在(zai)運行(xing)過程中發(fa)(fa)(fa)動機(ji)轉速變(bian)化(hua)范圍很大，發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)端(duan)電(dian)(dian)(dian)(dian)(dian)壓(ya)也將(jiang)隨(sui)發(fa)(fa)(fa)動機(ji)的(de)轉速變(bian)化(hua)而在(zai)很大范圍內變(bian)化(hua)。發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)對用電(dian)(dian)(dian)(dian)(dian)設(she)備供電(dian)(dian)(dian)(dian)(dian)和向蓄電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，都(dou)要求其電(dian)(dian)(dian)(dian)(dian)壓(ya)穩定，為了(le)使電(dian)(dian)(dian)(dian)(dian)壓(ya)始終保持在(zai)某一數(shu)值基本不(bu)變(bian)，就必須對發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)進行(xing)調節(jie)。

豐田佳美(進口)簡介

豐(feng)田(tian)佳美(mei)前后開(kai)始進入中國市場，當(dang)年的(de)佳美(mei)在豐(feng)田(tian)車(che)系中屬(shu)中高級轎車(che)，是初發(fa)展出來(lai)的(de)新一代車(che)型。外形并(bing)不追(zhui)求氣派，而(er)著重突出個性。因為佳美(mei)定位在家庭用車(che)，而(er)非公務車(che)，故車(che)身顏色(se)不以(yi)黑色(se)為主，多配彩漆，即有各種顏色(se)，較為活潑。
