天氣轉涼(liang)，吸(xi)(xi)糞車(che)(che)(che)等專(zhuan)用汽車(che)(che)(che)難(nan)以啟(qi)(qi)動(dong)(dong)越(yue)來(lai)越(yue)常見。部分吸(xi)(xi)糞車(che)(che)(che)客(ke)戶到(dao)廠試車(che)(che)(che)的(de)時候(hou)，也(ye)會發(fa)下(xia)部分吸(xi)(xi)糞車(che)(che)(che)等專(zhuan)用汽車(che)(che)(che)現車(che)(che)(che)比較(jiao)難(nan)打火，于是認為車(che)(che)(che)子存(cun)在質量問題。其實發(fa)動(dong)(dong)機(ji)難(nan)以啟(qi)(qi)動(dong)(dong)的(de)原因(yin)很多(duo)，并不一(yi)定都是質量存(cun)在問題。下(xia)面吸(xi)(xi)糞車(che)(che)(che)廠家湖北(bei)俊龍專(zhuan)用汽車(che)(che)(che)有限公司給您介紹一(yi)下(xia)發(fa)動(dong)(dong)機(ji)難(nan)以啟(qi)(qi)動(dong)(dong)的(de)原因(yin)。

汽車發動(dong)(dong)(dong)機一切正常的(de)情況(kuang)(kuang)下，啟(qi)動(dong)(dong)(dong)機或蓄(xu)(xu)(xu)(xu)電(dian)(dian)(dian)池有(you)故障(zhang)都(dou)會(hui)使(shi)發動(dong)(dong)(dong)機難以啟(qi)動(dong)(dong)(dong)，甚(shen)至不能(neng)啟(qi)動(dong)(dong)(dong)。遇(yu)此情況(kuang)(kuang)，首先要(yao)了(le)解(jie)啟(qi)動(dong)(dong)(dong)機與(yu)蓄(xu)(xu)(xu)(xu)電(dian)(dian)(dian)池的(de)使(shi)用情況(kuang)(kuang)，以便大致判斷(duan)故障(zhang)部位。若蓄(xu)(xu)(xu)(xu)電(dian)(dian)(dian)池使(shi)用時(shi)間(jian)已經超過1年，應重點檢查其技術狀況(kuang)(kuang)；若蓄(xu)(xu)(xu)(xu)電(dian)(dian)(dian)池使(shi)用時(shi)間(jian)較短，而啟(qi)動(dong)(dong)(dong)機長時(shi)間(jian)未檢修(xiu)，則應從啟(qi)動(dong)(dong)(dong)機查起。大多(duo)數不能(neng)啟(qi)動(dong)(dong)(dong)的(de)狀況(kuang)(kuang)都(dou)是(shi)因為(wei)蓄(xu)(xu)(xu)(xu)電(dian)(dian)(dian)瓶(ping)虧(kui)電(dian)(dian)(dian)，這種情況(kuang)(kuang)只需要(yao)找一個滿電(dian)(dian)(dian)的(de)蓄(xu)(xu)(xu)(xu)電(dian)(dian)(dian)瓶(ping)搭火即(ji)可(ke)。另外(wai)最(zui)常見的(de)就(jiu)是(shi)油箱虧(kui)油。這就(jiu)需要(yao)加油然(ran)后(hou)手動(dong)(dong)(dong)泵油。但是(shi)具(ju)體情況(kuang)(kuang)具(ju)體分析，還是(shi)要(yao)根據啟(qi)動(dong)(dong)(dong)時(shi)的(de)故障(zhang)現象(xiang)進(jin)行(xing)分析和處理：

1、啟動(dong)(dong)(dong)時(shi)只聽到啟動(dong)(dong)(dong)機(ji)電磁開關“咯(ge)咯(ge)”聲，或首次啟動(dong)(dong)(dong)時(shi)啟動(dong)(dong)(dong)機(ji)帶動(dong)(dong)(dong)曲軸緩轉幾下，繼(ji)而出現啟動(dong)(dong)(dong)電磁開關“咯(ge)咯(ge)”響，但(dan)曲軸卻不轉動(dong)(dong)(dong)。此(ci)現象一般屬(shu)于蓄電池“斷格(ge)”故(gu)障。

2、臨(lin)時停車每次都能(neng)啟動，但(dan)停車時間較長或第二天啟動時卻只能(neng)使曲軸轉一(yi)下。此現象(xiang)屬于(yu)蓄(xu)電(dian)(dian)池(chi)(chi)自放電(dian)(dian)嚴(yan)重，其極板(ban)、隔板(ban)嚴(yan)重老化，說明該蓄(xu)電(dian)(dian)池(chi)(chi)已經接近(jin)報(bao)廢(fei)。

3、啟動(dong)(dong)(dong)時啟動(dong)(dong)(dong)機(ji)突然(ran)轉動(dong)(dong)(dong)無力，并伴有(you)燒(shao)橡膠氣味或蓄電池處(chu)有(you)煙冒(mao)出，多(duo)屬極樁、極樁夾(jia)子接觸不良而發熱燒(shao)損。

4、若啟動(dong)時啟動(dong)機驅動(dong)齒輪與發動(dong)機飛輪齒圈(quan)發出撞擊的(de)(de)空轉聲，其(qi)原因(yin)有二：一是飛輪齒圈(quan)的(de)(de)嚙合切(qie)入(ru)面變形；二是啟動(dong)機驅動(dong)齒輪與飛輪齒圈(quan)的(de)(de)間隙太大(da)。兩(liang)者(zhe)無法嚙合，發動(dong)機也就不能啟動(dong)。

5、電(dian)源總(zong)開關一接(jie)通(tong)，啟(qi)動(dong)(dong)(dong)(dong)機驅動(dong)(dong)(dong)(dong)齒(chi)(chi)輪就(jiu)和(he)飛(fei)輪齒(chi)(chi)圈嚙合在(zai)一起(qi)(qi)轉(zhuan)動(dong)(dong)(dong)(dong)。出(chu)現這種故障，一是(shi)啟(qi)動(dong)(dong)(dong)(dong)機電(dian)磁開關的保持線圈錯(cuo)接(jie)在(zai)了電(dian)源接(jie)線柱上；二是(shi)鑰匙(chi)開關上的3根(gen)線接(jie)錯(cuo)，判斷方法是(shi)：鑰匙(chi)在(zai)“0”位置時(shi)啟(qi)動(dong)(dong)(dong)(dong)機驅動(dong)(dong)(dong)(dong)齒(chi)(chi)輪不轉(zhuan)，在(zai)“2”位置時(shi)啟(qi)動(dong)(dong)(dong)(dong)電(dian)機驅動(dong)(dong)(dong)(dong)齒(chi)(chi)輪與飛(fei)輪齒(chi)(chi)圈嚙合一起(qi)(qi)轉(zhuan)動(dong)(dong)(dong)(dong)。

6、啟(qi)(qi)動(dong)開(kai)關(guan)(guan)轉(zhuan)到啟(qi)(qi)動(dong)位置發動(dong)機不能啟(qi)(qi)動(dong)，也無其他現象。這種故障，一是(shi)鑰匙、開(kai)關(guan)(guan)因磨損而未(wei)接通啟(qi)(qi)動(dong)電(dian)路；二是(shi)啟(qi)(qi)動(dong)機繼電(dian)器未(wei)接通啟(qi)(qi)動(dong)機電(dian)磁開(kai)關(guan)(guan)電(dian)路；三(san)是(shi)電(dian)源開(kai)關(guan)(guan)未(wei)接通主電(dian)路。

7、啟動(dong)時只有輕微“嗒”的一聲，再(zai)無任何反(fan)應，這是啟動(dong)繼電器發(fa)(fa)卡所致。這時只要(yao)按一下電磁(ci)鐵尾部，迫使電磁(ci)鐵前移(yi)，即可將啟動(dong)電路接(jie)通，從而使發(fa)(fa)動(dong)機啟動(dong)。
