VARIABLE DYNAMIC EFFECT INTAKE-AIR (VDI) SOLENOID VALVE CONSTRUCTION/OPERATION


BHE011318740T06

• Composed of a solenoid coil, spring, plunger, and filter.

Energized
• When the solenoid coil is energized, the plunger is pulled back. Pulling the plunger back opens the passage between ports A and B. Due to this, intake manifold vacuum is applied to the actuator.
De-energized
• Passage of port A is closed by the reaction force of the spring, and the passage between ports B and C is opened. Due to this, BARO is applied to the actuator.
