Problems solved by technology

[0012] However, limited by knowledge, skills, and tools, the maintenance techniques of after-sales service stations are uneven, and the effectiveness of existing equipment is extremely limited, so the performance of the repaired injectors cannot be guaranteed.
Most drivers no longer accept repairs and prefer to simply replace the injectors with new ones, thus having to incur expensive replacement costs
In addition, a large number of faulty injectors were discarded, resulting in a great waste of resources
