電(dian)(dian)(dian)子(zi)扇(shan)(shan)(shan)馬達電(dian)(dian)(dian)機電(dian)(dian)(dian)子(zi)風扇(shan)(shan)(shan)的工(gong)(gong)作原理是汽車電(dian)(dian)(dian)子(zi)風扇(shan)(shan)(shan)由恒溫(wen)器(qi)控制。當水溫(wen)上(shang)升到上(shang)限(xian)時(shi)(shi)，溫(wen)控器(qi)接(jie)通(tong)電(dian)(dian)(dian)源(yuan)，風扇(shan)(shan)(shan)開始工(gong)(gong)作。當水溫(wen)降至下限(xian)時(shi)(shi)，溫(wen)控器(qi)關閉電(dian)(dian)(dian)源(yuan)，風扇(shan)(shan)(shan)停(ting)止工(gong)(gong)作。功能(neng)是冷(leng)卻發動機水箱(xiang)。
以下(xia)是(shi)電子風扇不轉的(de)原(yuan)因(yin):
1。電(dian)機潤(run)滑不(bu)良，電(dian)風扇不(bu)轉(zhuan)，安裝扇葉后(hou)無法拖動電(dian)機；
2、電(dian)機過(guo)熱，電(dian)機過(guo)熱還(huan)會(hui)造成電(dian)機負(fu)載能力變(bian)(bian)差，電(dian)機有效功率變(bian)(bian)低，導致(zhi)無法驅動負(fu)載；
3.當啟動電容(rong)容(rong)量變(bian)小時，電容(rong)容(rong)量會(hui)變(bian)小，導致電機啟動轉矩變(bian)小，無法驅動負載；
4.電(dian)(dian)機(ji)(ji)使用(yong)時間過(guo)長。電(dian)(dian)風(feng)扇(shan)用(yong)久了，電(dian)(dian)機(ji)(ji)會磨損，電(dian)(dian)機(ji)(ji)的軸套(tao)也容易燒壞。如果長時間使用(yong)電(dian)(dian)機(ji)(ji)，電(dian)(dian)機(ji)(ji)內(nei)阻也會增大，負載能(neng)力下降(jiang)，導(dao)致無法帶動(dong)扇(shan)葉轉動(dong)。
皮卡(ka)由(you)于強調牽引(yin)能力,因此(ci)多數采(cai)用柴油發(fa)動機,此(ci)次艾森ECU升級(ji)的大通T60就搭載(zai)了(le)一臺2.8T四缸渦輪增壓(ya)(ya)柴油發動(dong)機(ji),采用了(le)VGT可變截面渦輪增壓(ya)(ya)器的設計(ji)以及博世第三代(dai)高壓(ya)(ya)共軌
