SUCTION CONTROL VALVE [SKYACTIV-D 2.2]
id0114z7707500
Purpose, Function
• By controlling the supply pump intake amount, the suction control valve controls the pressure pump feed amount and the pressure inside the fuel distribution pipe.
Construction
• The suction control valve is built into the supply pump.
• The suction control valve consists of the valve, valve body, armature, and teflon bush.
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.
