噴(pen)(pen)(pen)油(you)器修理包-噴(pen)(pen)(pen)油(you)器就是大(da)家俗稱的噴(pen)(pen)(pen)油(you)嘴了(le),噴(pen)(pen)(pen)油(you)器是供油(you)系統中(zhong)最重要的部件,它實(shi)質是一(yi)個電磁閥。

噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)的(de)(de)(de)(de)作用是按照發(fa)動(dong)(dong)機(ji)ECU計算出(chu)的(de)(de)(de)(de)噴(pen)(pen)(pen)(pen)射正(zheng)時和脈寬(kuan)，向進(jin)氣歧管或氣缸內噴(pen)(pen)(pen)(pen)射燃油(you)(you)(you)(you)。噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)實際上(shang)是一個電(dian)磁(ci)閥，ECU通過控制其電(dian)磁(ci)閥線圈(quan)的(de)(de)(de)(de)電(dian)流通斷，來控制噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)的(de)(de)(de)(de)工作。噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)是維持發(fa)動(dong)(dong)機(ji)運(yun)轉的(de)(de)(de)(de)重要部件，由噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)體、噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)嘴(zui)、支座、彈(dan)簧等組成(cheng)；由噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)供油(you)(you)(you)(you)口泵(beng)進(jin)高(gao)壓(ya)油(you)(you)(you)(you)，噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)器(qi)體內產生高(gao)壓(ya)作用到(dao)噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)嘴(zui)錐面上(shang)，當(dang)油(you)(you)(you)(you)壓(ya)超過調(diao)定值時噴(pen)(pen)(pen)(pen)油(you)(you)(you)(you)嘴(zui)閥芯開啟，高(gao)壓(ya)油(you)(you)(you)(you)從噴(pen)(pen)(pen)(pen)嘴(zui)小(xiao)孔噴(pen)(pen)(pen)(pen)出(chu)，呈(cheng)霧狀(zhuang)到(dao)發(fa)動(dong)(dong)機(ji)缸筒(tong)里燃燒(shao)，使活塞往復(fu)運(yun)行。
