How to detect car exhaust without dynamic detection?

Some car owners still believe that the previous car annual inspection was not standardized and professional enough, but now it is professional, but it feels like a "hammer for a hammer"... Exhaust gas testing has eliminated dynamic detection methods and replaced them with "OBD data reading methods"; That is to say, the vehicle fault diagnosis equipment is connected to the on-board computer through the vehicle OBD pretext, and the exhaust data recorded by the on-board computer is directly authorized.

The answer is: GPF/DPF cannot be removed. After removal, the on-board computer will report an error. Even if the owner can ignore it or the dashboard does not prompt, the data will still be recorded; Can these cars still pass the exhaust detection process if they are found to have no or missing exhaust detection data during the annual inspection? Obviously not possible.

This is professionalism.

There are many changes in the new car inspection project. The latest standard is to replace the exhaust detection method, cancel suspension detection, cancel speed detection, cancel handbrake detection, and cancel noise detection; Increase tire wear detection, increase vehicle wheelbase detection, and increase vehicle chassis detection. Isn't it quite a lot? In fact, it's not much. There are actually more car inspection projects in European, American, or Japanese countries. A system of inspection can have more than 100 inspection projects, and most of them are "finding faults" projects; The key point is that the testing cost is several thousand yuan, and Japan's one-stop service testing costs over ten thousand yuan. So the current domestic automobile annual inspection has not yet begun to truly professionalize, but it has already made fuel vehicles somewhat difficult; There is no good solution to the problem with the particulate matter trap. Try to drive on a smooth road and drive for a while longer.
