發電機調節器簡介

汽車(che)(che)的(de)供(gong)電(dian)(dian)(dian)系統(tong)是由汽車(che)(che)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)和發(fa)電(dian)(dian)(dian)機組成，發(fa)電(dian)(dian)(dian)機負(fu)責(ze)對(dui)電(dian)(dian)(dian)池(chi)(chi)進行充電(dian)(dian)(dian)，使電(dian)(dian)(dian)池(chi)(chi)長(chang)期(qi)保持(chi)在足電(dian)(dian)(dian)狀態。電(dian)(dian)(dian)池(chi)(chi)和發(fa)電(dian)(dian)(dian)機負(fu)責(ze)對(dui)全車(che)(che)的(de)電(dian)(dian)(dian)器進行供(gong)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)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)調(diao)節器的(de)主要作用是為了控制發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)在額定(ding)值內(nei)(nei)，由于發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)與發(fa)動(dong)機(ji)(ji)的(de)傳動(dong)比是固定(ding)的(de)，所以發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)轉(zhuan)速(su)將(jiang)隨發(fa)動(dong)機(ji)(ji)轉(zhuan)速(su)的(de)變(bian)(bian)(bian)化而變(bian)(bian)(bian)化。汽車在運行(xing)過程中發(fa)動(dong)機(ji)(ji)轉(zhuan)速(su)變(bian)(bian)(bian)化范圍(wei)很(hen)大，發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)端(duan)電(dian)(dian)(dian)(dian)(dian)壓(ya)也(ye)將(jiang)隨發(fa)動(dong)機(ji)(ji)的(de)轉(zhuan)速(su)變(bian)(bian)(bian)化而在很(hen)大范圍(wei)內(nei)(nei)變(bian)(bian)(bian)化。發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)對用電(dian)(dian)(dian)(dian)(dian)設備供電(dian)(dian)(dian)(dian)(dian)和向(xiang)蓄電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，都(dou)要求(qiu)其電(dian)(dian)(dian)(dian)(dian)壓(ya)穩定(ding)，為了使電(dian)(dian)(dian)(dian)(dian)壓(ya)始終(zhong)保持(chi)在某(mou)一數值基本(ben)不變(bian)(bian)(bian)，就必(bi)須(xu)對發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)進(jin)行(xing)調(diao)節。

豐田Venza(進口)簡介

豐田(tian)Sienna基于修正過的凱(kai)美瑞(rui)平臺(tai)，新款Sienna車身長度可能會有所加(jia)長，從而提(ti)供更為寬(kuan)敞的內部(bu)空(kong)間。既然使用凱(kai)美瑞(rui)的平臺(tai)，那么新款Sienna可能會選擇凱美瑞的(de)動力(li)系(xi)列，包括一(yi)(yi)款(kuan)最大(da)輸(shu)出(chu)功率268馬(ma)力(li)的(de)3.5L V6發(fa)動機，以(yi)及一(yi)(yi)款(kuan)最大(da)輸(shu)出(chu)功率147馬(ma)力(li)的(de)2.4L四缸發(fa)動機。
