Problems solved by technology

The way of manual positioning is that there is a risk that the fuel injection pump will fall off and hurt people or damage the fuel injection pump, and the second is that the movement of the fuel injection pump will cause the gear to shift.
The reliability of this method is not high, and the assembly efficiency is low, which cannot meet the production requirements
