奥迪A6L加速不畅、无法高速行驶!

来源:http://www.lutongqixiu.com/ 日期:2019-05-31 发布人:admin
  2005年奥迪a6l2.4的行驶里程超过22.4万公里。用户反馈:汽车没有自由加速,高速上很难。
  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.
  故障诊断:(1)首先利用VA56150检测1柱与2柱混合物过厚的故障代码。检查燃油压力是否正常,喷嘴没有滴漏现象,尽量更换火花塞和点火线圈无效。分析汽车推动了220000公里,三个催化转换器块的可能性大,检查后发现三个催化转换器已被封堵,更换三催化转换器后测试正常,不平滑加速故障诊断,但在洗车过程中发现,有时开始着急,小型加速器燃料不走车。
  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)第二次试验确定故障发生在低速前进或倒车和行驶方向。使用5052数据块对数据块进行读取,发现混频器仍集中在25%的调节下。检查碳罐电磁阀,更换后仍有故障。我们试图更换喷嘴、氧气传感器和燃油泵,并更换了阀门和发动机控制单元。读取传输数据也未发现异常。

  (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)调整思路。由于大多数故障发生在低速和行驶方向,人们怀疑发动机功率不足。汽缸压力测量发现,4、5、6缸气缸压力在9条,与1、2、3缸缸汽缸压力大约是12小节,分析三个汽缸阀问题可能,内窥镜检查也没有发现压力缸的迹象,三元催化剂已经改变,1列进口有问题吗?试图更换进气歧管的故障仍然存在,但不得不对发动机进行拆卸,发现4缸、5缸、6缸活塞环沟槽存在断裂损坏,导致气缸压力偏低,更换活塞环和活塞环出现故障。
  (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:更换活塞和活塞环。
  Troubleshooting: Replacement of piston and piston ring.
  故障总结:发动机功率也应考虑起动和起动故障。
  Fault Summary: Engine power should also consider starting and starting faults.
