SUCTION CONTROL VALVE [SKYACTIV-D 2.2]

id0114z7707500


Purpose, Function

•  The suction control valve controls the common rail pressure by adjusting the intake amount to the supply pump and controlling the discharge amount.

Construction

•  The suction control valve is built into the supply pump.

•  The suction control valve consists of the valve, valve body, and armature.

Operation

•  The intake amount controls the solenoid drive current by duty control, and adjusts it by changing the valve opening angle. When the solenoid drive current is small, the intake amount decreases, and when it is large the intake amount increases.

Non-energization (closed)

•  The port in the valve is closed.

Energization (open)

•  The port in the valve opens and fuel is sent to the high pressure chamber.
