Function
When the solenoid coil is energized, the nozzle needle is raised about 0.1 mm by the solenoid armature against the force of the coil spring.
Fuel escapes through the outlet hole and is sprayed into the intake port in a finely atomized spray.
Fuel injection valves are actuated by mass impulses from the ME-SFI [ME] control unit (N3/10).
