①柴油中有水，水在氣缸內(nèi)蒸發(fā)成水蒸氣，從排氣管排出。
②氣缸蓋螺栓松動(dòng)或氣缸墊沖壞，使冷卻水進(jìn)入氣缸。
③氣缸體或氣缸蓋的某處有沙眼或裂紋，水進(jìn)入氣缸蒸發(fā)排出。

6 、挖掘機(jī)起動(dòng)困難或不能起動(dòng)，排氣管大量冒灰白煙的診斷。發(fā)動(dòng)機(jī)起動(dòng)困難，排氣管排出大量的灰白煙為柴油蒸氣。
① 發(fā)動(dòng)機(jī)溫度過(guò)低，柴油不易蒸發(fā)燃燒。
② 噴油器霧化不良
③ 供油時(shí)間過(guò)晚。
④ 供油量過(guò)少，混合氣過(guò)稀。
⑤ 氣缸漏氣量過(guò)多，壓縮終了不能達(dá)到著火溫度。

① 起動(dòng)機(jī)與飛輪齒嚙合不良。齒圈與起動(dòng)機(jī)齒輪在起動(dòng)發(fā)動(dòng)機(jī)時(shí)會(huì)發(fā)生撞擊，造成牙齒損壞或牙齒單面磨損。若牙齒連續(xù)三個(gè)以上損壞或磨損嚴(yán)重，起動(dòng)機(jī)齒輪與齒圈牙齒便難以嚙合。
② 粘缸。發(fā)動(dòng)機(jī)溫度過(guò)高時(shí)停車熄火，熱量難以散出，高溫下的活塞環(huán)與氣缸粘連，冷卻后無(wú)法起動(dòng)。
③ 曲軸抱死。由于潤(rùn)滑系故障或缺機(jī)油造成滑動(dòng)軸承干摩擦，以致終抱死曲軸而無(wú)法起動(dòng)。
④ 噴油泵柱塞卡死。

700-92-34000-YA CONTROL VALVE1、挖掘機(jī)在冬季起動(dòng)為什么困難？不僅決定于本身的技術(shù)狀況，還受外界氣溫的影響。冬季低溫下起動(dòng)更困難，主要是由如下原因所致：
⑴冬季氣候寒冷，環(huán)境溫度低，機(jī)油粘度增大，各運(yùn)動(dòng)機(jī)件的摩擦阻力增加，使起動(dòng)轉(zhuǎn)速降低，難以起動(dòng)。
⑵蓄電池容量隨溫度下降而減少，使起動(dòng)轉(zhuǎn)速進(jìn)一步降低。
⑶由于起動(dòng)轉(zhuǎn)速降低，壓縮空氣滲漏增多，氣缸壁散熱量增大，致使壓縮終了時(shí)空氣的溫度和壓力大為降低，使柴油發(fā)火的延遲期增長(zhǎng)，嚴(yán)重時(shí)甚至不能燃燒。

⑷低溫下的柴油粘度增大，使噴射速度降低，加上空氣在壓縮終了時(shí)的旋流速度、溫度和壓力都比較低，使噴入氣缸的柴油霧化質(zhì)量差，難以與空氣迅速形成良好的可燃?xì)怏w并及時(shí)發(fā)火燃燒，甚至不能著火，導(dǎo)致起動(dòng)困難。
