Since the launch of the national four heavy truck, some Truck drivers were surprised to find that the muffler of their car would be blocked after a period of use.
Some truck drivers will ask, how can the silencer be blocked when we arrive at the fourth national day? There was no problem with the third car. That’s because, at the Fourth National Congress, most domestic heavy trucks are equipped with an SCR post-treatment system, and there are more catalyst carriers for catalytic reaction in the muffler.
In order to make the tail gas better contact with the silencer catalyst for better catalytic reaction, the catalyst carrier is designed with many small round holes.
