It is a N.O. solenoid valve.

They are connected to the EDC ECU on connector A.

The resistance of each injector coil is 0.56 - 0.57 Ohm.

The electroinjector can be considered as consisting of 2 parts:

- actuator - atomizer including pressure rod, needle and nozzle;

- control solenoid valve including coil and pilot valve.

The solenoid valve controls atomizer needle lift.

INJECTION START

When coil is energized, lock pin moves upward.

The control volume fuel flows to return duct causing control volume pressure drop.

At the same time, fuel pressure in pressure chamber causes needle uplift and therefore fuel injection in cylinder.

END OF INJECTION

When coil is de-energized, lock pin returns to lock position to look for a force balance such to return to needle close position and
stop injection.
