Fuel injection pump fuel injection timing indicator

摘要

This research institute starts the fuel injection time marking device of fuel injection pump.In this study, the shell (1) of the fuel injection pump is installed in the plunger (2), which moves back and forth from the cover shaft. The plunger (4) of the compressed fuel is a fixed scale (6), and the other scales (6) can move back and forth, penetrate the plunger barrel (2) and expose outwards, and the above It is characterized by five rings (7) between the scale (6) and the barrel (2).
