How can you judge if the exhaust pipe is clogged?

  1. When starting the car, the engine ignites and injects fuel, but the car just cannot start, most of which is because the exhaust pipe is blocked.
  2. It is difficult to increase the speed of the vehicle, and it feels weak when accelerating. The exhaust pipe is blocked, resulting in poor exhaust flow, which leads to a decrease in intake volume.
  3. When the three-way catalytic is damaged, it will easily cause the exhaust pipe to be blocked. When the engine is accelerating rapidly or closing the throttle, you will hear the noise of the exhaust pipe, so be careful.
  4. Due to the blockage of the exhaust pipe, the engine power is not good, so it is necessary to step on the accelerator frequently to open the throttle valve to obtain more power, and the ECU will control the vehicle to downshift according to the wide opening of the throttle valve. The vehicle will frequently experience forced downshifting and the fuel consumption will increase.

If the exhaust pipe is blocked, you can try the following methods to deal with it:

  1. Check the exhaust pipe: First check whether there are obvious objects or blockages in the exhaust pipe, such as garbage, debris, etc. If there are shallow blockages, you can try to clear them manually.
  2. Use exhaust pipe cleaner: There are some special exhaust pipe cleaners on the market, which can be used by spraying or pouring into the exhaust pipe. Follow product directions for the proper use of cleaners.
  3. Use high-pressure air: Use professional high-pressure air tools, such as air guns or compressed air machines, to flush the exhaust pipe. This can help clear deeper blockages.
  4. Find professional technical support: If the above methods are invalid or you are not sure how to deal with it, it is recommended to seek professional technical support. An auto repair shop or mechanic can provide a more accurate diagnosis and solution.

Important Note:

When dealing with a clogged exhaust, remember safety first. Make sure to take appropriate safety measures during operation and follow relevant guidelines or expert advice.
