排解汽油壓力、減少油耗。
1、Ec718燃油濾清器的回油管其主要作用就是給發動機多余的燃油有一個通道能回到油箱當中,能夠起到排解汽油壓力、減少油耗的效果。
2、回油管則能消除噴油器無規律噴油甚至卡死針閥的情況,確保柴油機的正常工作。
這是燃油燃燒器油的調試過程之一,具體操作如下
一、燃油燃燒器調試之前的檢查涵蓋三個方面
1. 查看燃油是否到位,燃油管路的是否干凈通暢,閥門是否已開啟。
2. 有無管路泄露現象,管道安裝是否合理。
3. 進油回油管路是否安裝正確,回油管不允許安裝閥門
二、燃油燃燒器調試前內部檢查
1. 燃燒機的油嘴是否安裝和點火電極是否調整好。
2. 電機旋轉的方向是否正確。
3. 外部的電路聯接是否符合要求。
4. 根據線路情況對燃油燃燒器進行冷態模擬
汽車回油管的位置在噴油嘴那里。
通常情況下進油管是在噴油嘴的上面,而回油管是在下面,而且是從里面分支出來的,而且進油管一般都比回油管要大些,進油管是連接燃油濾芯的那根。
是供油管,可以用以下方法檢查油壓:
1.卸壓:先拔下燃油泵保險絲、繼電器或油泵插頭,再起動發動機,直至發動機自行熄火后,再次起動發動機2~3次,然后拆下蓄電池負極。
2.安裝燃油壓力表:將燃油壓力表串接在進油管中,帶測壓口的車輛將燃油壓力表連接到測壓口上,在拆卸油管時要用一塊毛巾或棉布墊在油管接口下,防止燃油泄露在地上。
3.檢測油壓:靜態油壓:不起動發動機,用跨接線連接油泵診斷接頭上的兩個端子(豐田車系的“+B”與“FB”端子),并將點火開關轉至“ON”位置,令油泵工作,靜態油壓一般在300 KPa左右。
柴油康明斯發動機燃油泵輸油管和回油管裝反了,對發動機會造成損傷。
柴油的油管,輸油管經過柴濾、油水分離器的過濾,回油管沒有過濾,所以裝返了對高壓泵損傷極大,噴油器容易堵塞、發動機逐漸運轉不平穩動力下降。
另外,兩根管子接反的情況下,會導致發動機會供不上油。裝反了要及時更換回來。
