比亞迪發動機抖動是什么原因

1、發動機積碳嚴重

造(zao)成汽(qi)車抖動(dong)(dong)(dong)(dong)最常見的(de)(de)原(yuan)因就是節氣(qi)(qi)門(men)過(guo)(guo)臟或噴(pen)油(you)嘴積(ji)炭過(guo)(guo)多。當(dang)發(fa)動(dong)(dong)(dong)(dong)機內部的(de)(de)積(ji)碳(tan)過(guo)(guo)多時(shi)，冷(leng)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)噴(pen)油(you)頭噴(pen)出的(de)(de)汽(qi)油(you)會(hui)被積(ji)碳(tan)大(da)(da)量吸(xi)(xi)收，導致冷(leng)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)的(de)(de)混合氣(qi)(qi)過(guo)(guo)稀，使得啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)困難，這種狀況(kuang)下，只有等到積(ji)碳(tan)吸(xi)(xi)收的(de)(de)汽(qi)油(you)飽和，才容(rong)易著(zhu)車，著(zhu)車后吸(xi)(xi)附在積(ji)碳(tan)上的(de)(de)汽(qi)油(you)又會(hui)被發(fa)動(dong)(dong)(dong)(dong)機的(de)(de)真(zhen)空(kong)吸(xi)(xi)力(li)吸(xi)(xi)入汽(qi)缸內燃(ran)燒(shao)，又使混合氣(qi)(qi)變濃(nong)，發(fa)動(dong)(dong)(dong)(dong)機的(de)(de)可(ke)燃(ran)混合氣(qi)(qi)時(shi)稀時(shi)濃(nong)，造(zao)成冷(leng)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)后怠速(su)抖動(dong)(dong)(dong)(dong)。氣(qi)(qi)溫越低，冷(leng)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)所需要的(de)(de)油(you)量越大(da)(da)，積(ji)碳(tan)的(de)(de)存在就越會(hui)影響冷(leng)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)的(de)(de)順(shun)利與(yu)否。

解決辦法：清洗(xi)油路，檢查怠速馬達是否(fou)有(you)積碳應該清洗(xi)。

2、點火系統問題

檢查一(yi)下火花(hua)塞、高壓導(dao)線和點火線圈的工作(zuo)狀況，點火系統工作(zuo)不(bu)良，火花(hua)塞跳火狀況不(bu)好同樣會導(dao)致這(zhe)類故障現(xian)象。

解決辦法：檢(jian)查火(huo)花塞(sai)是否積碳(tan)過多，更(geng)換火(huo)花塞(sai)。

3、油壓不穩

如(ru)(ru)果(guo)已(yi)經(jing)清理過發(fa)(fa)動(dong)機積碳、洗過節(jie)氣(qi)門、換(huan)過油(you)(you)墊(dian)以及火花塞等，仍然發(fa)(fa)現怠速時(shi)車身抖動(dong)，建(jian)議您到4S店檢查(cha)燃油(you)(you)供油(you)(you)壓(ya)力以及進氣(qi)壓(ya)力傳感器(qi)等是(shi)否正常(chang)，如(ru)(ru)果(guo)油(you)(you)泵供油(you)(you)壓(ya)力不正常(chang)或進氣(qi)壓(ya)力傳感器(qi)數值(zhi)錯誤(wu)和工作不良都會引發(fa)(fa)車身抖動(dong)。

解(jie)決辦法：檢(jian)查油壓(ya)，必要時更換部(bu)件(jian)。

4、發動機部件老化

汽車抖動(dong)(dong)還(huan)與引擎(qing)腳(jiao)(jiao)（又稱(cheng)機(ji)爪墊）老化有關。引擎(qing)腳(jiao)(jiao)其實(shi)是(shi)發(fa)動(dong)(dong)機(ji)的(de)避(bi)震系統，引擎(qing)腳(jiao)(jiao)負責(ze)吸收發(fa)動(dong)(dong)機(ji)在運轉時候的(de)細微抖動(dong)(dong)，如(ru)果引擎(qing)腳(jiao)(jiao)出現(xian)問(wen)題，這些震動(dong)(dong)就會(hui)傳到方向盤、駕(jia)駛(shi)室內，造成怠速時發(fa)生(sheng)抖動(dong)(dong)。

解(jie)決辦法：更換部件。

比亞迪發動機抖動多大算正常

開車(che)時只(zhi)要車(che)一抖，大(da)家就會說發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)抖動(dong)(dong)(dong)(dong)了(le)，并且下(xia)意識覺(jue)得問題很嚴重。其(qi)實發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)工作(zuo)時是(shi)免(mian)不了(le)發(fa)生抖動(dong)(dong)(dong)(dong)的，只(zhi)是(shi)在正常情況下(xia)，汽車(che)發(fa)動(dong)(dong)(dong)(dong)機(ji)(ji)的抖動(dong)(dong)(dong)(dong)應該(gai)很平(ping)穩(wen)、有規律。如(ru)果能明顯感覺(jue)到汽車(che)最近的抖動(dong)(dong)(dong)(dong)增大(da)或一直持(chi)續，那就要注意檢修了(le)。抖動(dong)(dong)(dong)(dong)有如(ru)下(xia)幾種(zhong)：高(gao)速抖動(dong)(dong)(dong)(dong)、怠速抖動(dong)(dong)(dong)(dong)，個別車(che)主甚至會發(fa)生跳動(dong)(dong)(dong)(dong)現象。
