挖機維修汽車電控共軌燃油可以噴射技術系統主要由一個電控單元、高壓油泵、共軌組件、電控噴油器工作以及企業各種信息傳感器等組成。修理挖掘機常見的挖掘機結構包括，動力裝置，工作裝置，回轉機構，操縱機構，傳動機構，行走機構和輔助設施等。挖掘機維修最重要的三個參數：操作重量（質量），發動機功率和鏟斗斗容。挖掘機修理最初挖(wa)掘機(ji)(ji)(ji)是手動(dong)的(de)(de)(de)，從(cong)發(fa)(fa)明到(dao)(dao)現(xian)在已經(jing)有一百(bai)三(san)十多年了，期(qi)間(jian)經(jing)歷(li)了由蒸汽(qi)驅(qu)(qu)動(dong)斗(dou)回(hui)轉挖(wa)掘機(ji)(ji)(ji)到(dao)(dao)電(dian)(dian)力(li)(li)驅(qu)(qu)動(dong)和(he)內燃(ran)(ran)機(ji)(ji)(ji)驅(qu)(qu)動(dong)回(hui)轉挖(wa)掘機(ji)(ji)(ji)、應(ying)用(yong)機(ji)(ji)(ji)電(dian)(dian)液一體化技(ji)術的(de)(de)(de)全自(zi)(zi)動(dong)液壓(ya)(ya)(ya)挖(wa)掘機(ji)(ji)(ji)的(de)(de)(de)逐步發(fa)(fa)展(zhan)過程(cheng)。高(gao)(gao)壓(ya)(ya)(ya)油(you)(you)(you)泵把高(gao)(gao)壓(ya)(ya)(ya)燃(ran)(ran)油(you)(you)(you)輸(shu)送(song)(song)(song)到(dao)(dao)共(gong)軌(gui)(gui)(gui)組(zu)(zu)(zu)(zu)件(jian)(jian)，通過對(dui)共(gong)軌(gui)(gui)(gui)組(zu)(zu)(zu)(zu)件(jian)(jian)內的(de)(de)(de)油(you)(you)(you)壓(ya)(ya)(ya)同時(shi)(shi)實現(xian)更加(jia)精確管理控(kong)(kong)(kong)制(zhi)(zhi)，使(shi)共(gong)軌(gui)(gui)(gui)組(zu)(zu)(zu)(zu)件(jian)(jian)內的(de)(de)(de)油(you)(you)(you)壓(ya)(ya)(ya)大小與柴油(you)(you)(you)機(ji)(ji)(ji)不同轉速變化無關，減(jian)少(shao)了油(you)(you)(you)壓(ya)(ya)(ya)脈(mo)動(dong)，減(jian)輕了對(dui)噴(pen)油(you)(you)(you)的(de)(de)(de)影響，因此我們也就克服了中國(guo)傳統(tong)研究柴油(you)(you)(you)機(ji)(ji)(ji)供油(you)(you)(you)安全系統(tong)的(de)(de)(de)缺點。電(dian)(dian)控(kong)(kong)(kong)單元內部控(kong)(kong)(kong)制(zhi)(zhi)要(yao)求(qiu)電(dian)(dian)控(kong)(kong)(kong)噴(pen)油(you)(you)(you)器(qi)(qi)的(de)(de)(de)噴(pen)油(you)(you)(you)量(liang)(liang)，噴(pen)油(you)(you)(you)量(liang)(liang)大小主要(yao)取決于(yu)(yu)共(gong)軌(gui)(gui)(gui)壓(ya)(ya)(ya)力(li)(li)和(he)電(dian)(dian)磁閥開啟學(xue)習時(shi)(shi)間(jian)比(bi)較長短，電(dian)(dian)控(kong)(kong)(kong)單元能(neng)定(ding)時(shi)(shi)定(ding)量(liang)(liang)地完成控(kong)(kong)(kong)制(zhi)(zhi)對(dui)于(yu)(yu)電(dian)(dian)控(kong)(kong)(kong)噴(pen)油(you)(you)(you)器(qi)(qi)噴(pen)射(she)到(dao)(dao)燃(ran)(ran)燒室中的(de)(de)(de)燃(ran)(ran)油(you)(you)(you)，從(cong)而使(shi)我國(guo)柴油(you)(you)(you)機(ji)(ji)(ji)的(de)(de)(de)空燃(ran)(ran)比(bi)最佳，良好霧(wu)化，著火(huo)溫度時(shi)(shi)間(jian)達(da)到(dao)(dao)最佳，著火(huo)能(neng)量(liang)(liang)沒有足夠，污(wu)染少(shao)。電(dian)(dian)控(kong)(kong)(kong)共(gong)軌(gui)(gui)(gui)燃(ran)(ran)油(you)(you)(you)噴(pen)射(she)操作系統(tong)的(de)(de)(de)組(zu)(zu)(zu)(zu)成結構(gou)見圖1-5- 1,電(dian)(dian)子工(gong)業控(kong)(kong)(kong)制(zhi)(zhi)程(cheng)序框圖見圖1-5-2。低壓(ya)(ya)(ya)燃(ran)(ran)油(you)(you)(you)泵將(jiang)燃(ran)(ran)油(you)(you)(you)輸(shu)送(song)(song)(song)到(dao)(dao)高(gao)(gao)壓(ya)(ya)(ya)輸(shu)油(you)(you)(you)泵(供油(you)(you)(you)泵)，高(gao)(gao)壓(ya)(ya)(ya)輸(shu)油(you)(you)(you)泵將(jiang)燃(ran)(ran)油(you)(you)(you)加(jia)壓(ya)(ya)(ya)送(song)(song)(song)人(ren)高(gao)(gao)壓(ya)(ya)(ya)共(gong)軌(gui)(gui)(gui)組(zu)(zu)(zu)(zu)件(jian)(jian)，高(gao)(gao)壓(ya)(ya)(ya)共(gong)軌(gui)(gui)(gui)組(zu)(zu)(zu)(zu)件(jian)(jian)中的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)由電(dian)(dian)控(kong)(kong)(kong)單元學(xue)生根據共(gong)軌(gui)(gui)(gui)壓(ya)(ya)(ya)力(li)(li)增加(jia)傳感器(qi)(qi)數據測量(liang)(liang)的(de)(de)(de)共(gong)軌(gui)(gui)(gui)壓(ya)(ya)(ya)力(li)(li)能(neng)夠按照自(zi)(zi)己(ji)需要(yao)教師進行自(zi)(zi)我調節，高(gao)(gao)壓(ya)(ya)(ya)共(gong)軌(gui)(gui)(gui)組(zu)(zu)(zu)(zu)件(jian)(jian)內的(de)(de)(de)燃(ran)(ran)油(you)(you)(you)經(jing)濟經(jing)過長期(qi)高(gao)(gao)壓(ya)(ya)(ya)油(you)(you)(you)管，根據實際柴油(you)(you)(you)機(ji)(ji)(ji)的(de)(de)(de)運行環境(jing)工(gong)況，出電(dian)(dian)控(kong)(kong)(kong)單元從(cong)預設的(de)(de)(de)MAP圖中結果確定(ding)選擇(ze)合適(shi)的(de)(de)(de)噴(pen)油(you)(you)(you)正時(shi)(shi)和(he)噴(pen)油(you)(you)(you)持(chi)續期(qi)，由電(dian)(dian)控(kong)(kong)(kong)噴(pen)油(you)(you)(you)器(qi)(qi)噴(pen)入汽(qi)缸。
