踏板高壓包故障(踏板高壓包故障會出現什么)

---

品牌:大眾捷達

生產日期:2013.7.29

變速箱:手動

排量:1.6L

故障現象:難著車要打幾次才打的早，著車后怠速正常空擋踩下油門踏板發動機轉速提不上來，發動機嚴重抖動排氣管伴有放炮聲，掛擋一放離合馬上就熄火的故障現象！

故障診斷:根據上述情況分析插入診斷電腦讀取故障碼發現一缸缺火，拆下一缸高壓包拆下火花塞進行檢查，拆火花塞的過程中輕輕一擰火花塞斷缸蓋里面了，這下麻煩了難搞了利用專用工具把斷火花塞取岀！

用缸壓表檢測發現缸壓正常更換火花塞后，清除故障碼著車再進行檢測，故障依舊讀取發動機數據流發現混合氣過希，空氣流量絕對壓力數值正常說明進氣歧管無漏氣現象，失火檢測四個缸沒報失火次數說明點火系統正常，然后接入油壓表檢測汽油壓力比正常值偏低了不少，基本可以確定故障點是油路的問題！

然后拆下油泵總成進行檢查如下圖:

油泵過濾網嚴堵塞，清洗濾網著車再進行檢查發現油壓依然不正常油泵噪音非常大不正常故障依舊，像這種情況下只能更換油泵總成了！

故障排除:更換油泵總成檢測汽油壓力正常，加速正常也不抖動了，打火一把就能著車路試加速正常故障排除！

非常感謝你能看完，喜歡記得關注喲！
