The recirculation pipe of Buick Excelle waste gas valve is broken.

There are many possible reasons for the rupture of the recirculation pipe of Buick Excelle waste gas valve. The following are some common reasons:

1. aging and wear: after a long period of use, the waste valve recirculation pipe will be affected by high temperature and high pressure, resulting in material aging and cracks or cracks.

2. Engine overheating: If the engine is overheated, the wastegate recirculation pipe may be subjected to excessive temperature and pressure, resulting in pipeline deformation or rupture.

3. Low-quality material: If the waste valve recirculation pipe is made of low-quality material, its high-temperature and high-pressure resistance may be poor and it is easy to break.

The reasons for the rupture of the waste gas valve recirculation pipe can be expanded. For example, improper maintenance, bad vehicle driving environment, design defects and other factors may have an impact on the rupture of the waste gas valve recirculation pipe. In addition, the rupture of the waste gas valve recirculation pipe will not only affect the normal operation of the waste gas treatment system, but also lead to the discharge not meeting the requirements of environmental protection and increase the pollution to the environment.

Therefore, it is necessary to check and replace the waste valve recirculation pipe in time, and also pay attention to the normal maintenance of the vehicle to reduce the risk of the waste valve recirculation pipe rupture.
