奧迪A6L加速不暢、無法高速行駛!

來源:http://www.nanofluidizer.com/ 日期:2019-05-31 發布人:admin
  2005年奧迪a6l2.4的行駛里程超過22.4萬公里。用戶反饋:汽車沒有自由加速,高速上很難。
  In 2005, Audi a6l2.4 traveled more than 224,000 kilometers. User Feedback: The car has no free acceleration, and it is very difficult at high speed.
  故障診斷:(1)首先利用VA56150檢測1柱與2柱混合物過厚的故障代碼。檢查燃油壓力是否正常,噴嘴沒有滴漏現象,盡量更換火花塞和點火線圈無效。分析汽車推動了220000公里,三個催化轉換器塊的可能性大,檢查后發現三個催化轉換器已被封堵,更換三催化轉換器后測試正常,不平滑加速故障診斷,但在洗車過程中發現,有時開始著急,小型加速器燃料不走車。
  Fault diagnosis: (1) First, the fault code of the mixture of 1 column and 2 column is detected by VA56150. Check whether the fuel pressure is normal and the nozzle does not drip. Replace the spark plug and ignition coil as far as possible is invalid. The analysis shows that the three catalytic converters have been blocked. After replacing the three catalytic converters, the test is normal and the fault diagnosis is not smooth. However, in the process of car washing, it is found that sometimes there is a start of anxiety and the fuel of the small accelerator is not running.
  (2)第二次試驗確定故障發生在低速前進或倒車和行駛方向。使用5052數據塊對數據塊進行讀取,發現混頻器仍集中在25%的調節下。檢查碳罐電磁閥,更換后仍有故障。我們試圖更換噴嘴、氧氣傳感器和燃油泵,并更換了閥門和發動機控制單元。讀取傳輸數據也未發現異常。

  (2) The second test confirms that the fault occurs in low-speed forward or reverse direction. Using 5052 data block to read the data block, it is found that the mixer is still concentrated in 25% regulation. Check the solenoid valve of the carbon tank, and there are still faults after replacement. We tried to replace nozzles, oxygen sensors and fuel pumps, and replaced valves and engine control units. No exception was found when reading the transmission data.
  (3)調整思路。由于大多數故障發生在低速和行駛方向,人們懷疑發動機功率不足。汽缸壓力測量發現,4、5、6缸氣缸壓力在9條,與1、2、3缸缸汽缸壓力大約是12小節,分析三個汽缸閥問題可能,內窺鏡檢查也沒有發現壓力缸的跡象,三元催化劑已經改變,1列進口有問題嗎?試圖更換進氣歧管的故障仍然存在,但不得不對發動機進行拆卸,發現4缸、5缸、6缸活塞環溝槽存在斷裂損壞,導致氣缸壓力偏低,更換活塞環和活塞環出現故障。
  (3) Adjusting the train of thought. Because most of the faults occur at low speeds and in the direction of driving, people suspect that the power of the engine is insufficient. Cylinder pressure measurement found that 4, 5, 6 cylinder pressure in 9, 1, 2, 3 cylinder cylinder pressure is about 12 sections, analysis of the three cylinder valve problems may not be found, endoscopy inspection did not find any signs of pressure cylinder, ternary catalyst has changed, a row of import problems? The failure to try to replace the intake manifold still exists, but had to disassemble the engine, found 4 cylinders, 5 cylinders, 6 cylinders. The groove of cylinder piston ring is broken and damaged, which results in low pressure of cylinder and failure of replacing piston ring and piston ring.
  故障排除:更換活塞和活塞環。
  Troubleshooting: Replacement of piston and piston ring.
  故障總結:發動機功率也應考慮起動和起動故障。
  Fault Summary: Engine power should also consider starting and starting faults.
