在汽油噴射系統中燃油泵是極其關鍵的部件,一旦燃油泵出現故障汽車就會出現各種不良的癥狀。下面我們來了解一下燃油泵出現故障會給汽車帶來哪些問題。
燃油泵故障會引起汽車
引擎可以點火,但無法啟動
燃料泵內部可能泄漏
過度的噪音
缺乏動力
加速時候卡頓無力
燃油泵相關的維修建議
大多數現代汽車電動燃油泵都是安裝在油箱內。一些車輛訪問面板看到燃油泵工作情況無需拆卸油箱就知道燃油泵好壞了。
油箱內的燃料泵要淹沒在燃油里用來幫助燃料泵保持低溫狀態。如果燃油泵運行時暴露在空氣中會很快損壞。
在更換燃油泵時燃油過濾器應該也更換新的
燃油過濾器阻塞或電氣系統驅動燃油泵問題可能導致癥狀類似于一個有故障的燃油泵。

汽油是高度易燃。維修店在確認是燃油泵的問題更換燃油泵之前電池應斷開連接和做適當的安全程序,以避免火災和人身傷害。

Related Repair Advice
-
Most modern vehicles use an electric fuel pump, which is mounted inside the fuel tank. Some vehicles have an access panel that can be removed to replace the pump without having to remove the fuel tank.
-
In-tank fuel pumps are submerged in fuel to help keep them cool. Running out of gas can damage the fuel pump.
-
The fuel filter should always be replaced when replacing the fuel pump
-
A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
-
Gasoline is highly flammable. When replacing the fuel pump, the battery should be disconnected and proper safety procedures followed to avoid fire and personal injury.
