How does a fuel injector valve work?
Injection valves comprise a valve body, which houses a magnet winding and a guide for the 

nozzle needle, and a nozzle needle with magnet armature. When the control unit applies 

voltage to the magnet winding, the nozzle needle rises up from its valve seat and releases a 

precision bore hole.
