西安重(zhong)康柴油(you)機配件有(you)限公(gong)司(si)小編(bian)把 要給大家注(zhu)重(zhong)介紹康明(ming)斯發動機配件的兩大系統，至(zhi)于具體是什么？請(qing)看下文：

一、點火系統

在(zai)汽油機(ji)中，氣(qi)缸內的(de)可燃(ran)混(hun)合氣(qi)是靠電(dian)火(huo)(huo)(huo)(huo)花(hua)(hua)(hua)點(dian)燃(ran)的(de)，為(wei)此在(zai)汽油機(ji)的(de)氣(qi)缸蓋(gai)上裝(zhuang)有火(huo)(huo)(huo)(huo)花(hua)(hua)(hua)塞(sai)，火(huo)(huo)(huo)(huo)花(hua)(hua)(hua)塞(sai)頭(tou)部伸入燃(ran)燒室內。能(neng)夠按時在(zai)火(huo)(huo)(huo)(huo)花(hua)(hua)(hua)塞(sai)電(dian)極間產生電(dian)火(huo)(huo)(huo)(huo)花(hua)(hua)(hua)的(de)全部設備稱為(wei)點(dian)火(huo)(huo)(huo)(huo)系，點(dian)火(huo)(huo)(huo)(huo)系通常(chang)由蓄電(dian)池、發電(dian)機(ji)、分電(dian)器、點(dian)火(huo)(huo)(huo)(huo)線(xian)圈(quan)和(he)火(huo)(huo)(huo)(huo)花(hua)(hua)(hua)塞(sai)等(deng)組成。

火(huo)花(hua)塞有一(yi)個(ge)中心電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)和一(yi)個(ge)側電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)，兩(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)之間(jian)(jian)是絕緣(yuan)的(de)。當在火(huo)花(hua)塞兩(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)間(jian)(jian)加上(shang)直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓并且電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓升高到(dao)一(yi)定值時，火(huo)花(hua)塞兩(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)之間(jian)(jian)的(de)間(jian)(jian)隙就(jiu)會被擊穿(chuan)而產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)火(huo)花(hua)，能(neng)夠(gou)在火(huo)花(hua)塞兩(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)間(jian)(jian)產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)火(huo)花(hua)所需要的(de) 低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓稱為(wei)擊穿(chuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓；能(neng)夠(gou)在火(huo)花(hua)塞兩(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)間(jian)(jian)產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)火(huo)花(hua)的(de)全(quan)部設備稱為(wei)發動(dong)機點火(huo)系(xi)。

二、起動系

要使發動(dong)(dong)(dong)機(ji)(ji)由靜止狀(zhuang)態(tai)過(guo)渡到(dao)工作(zuo)狀(zhuang)態(tai)，必須先用外力轉(zhuan)(zhuan)動(dong)(dong)(dong)發動(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)曲軸，使活(huo)塞(sai)作(zuo)往復運(yun)動(dong)(dong)(dong)，氣(qi)缸內的(de)(de)(de)可燃(ran)混合氣(qi)燃(ran)燒膨脹作(zuo)功，推動(dong)(dong)(dong)活(huo)塞(sai)向下運(yun)動(dong)(dong)(dong)使曲軸旋轉(zhuan)(zhuan)，發動(dong)(dong)(dong)機(ji)(ji)才能自行運(yun)轉(zhuan)(zhuan)，工作(zuo)循環才能自動(dong)(dong)(dong)進行。因(yin)此，曲軸在外力作(zuo)用下開(kai)始轉(zhuan)(zhuan)動(dong)(dong)(dong)到(dao)發動(dong)(dong)(dong)機(ji)(ji)開(kai)始自動(dong)(dong)(dong)地(di)怠速運(yun)轉(zhuan)(zhuan)的(de)(de)(de)全(quan)過(guo)程(cheng)，稱(cheng)(cheng)為發動(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)起動(dong)(dong)(dong)。完成(cheng)起動(dong)(dong)(dong)過(guo)程(cheng)所(suo)需的(de)(de)(de)裝置，稱(cheng)(cheng)為發動(dong)(dong)(dong)機(ji)(ji)的(de)(de)(de)起動(dong)(dong)(dong)系統(tong)。
