SUCTION CONTROL VALVE FUNCTION [MZR-CD (RF Turbo)]

id0114f1146700
• 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.
• The intake amount is determined by the total opening size of the valve as controlled by the duty value of the solenoid actuation current.
• The duty solenoid can adjust the open and close time ratio to control the intake amount by changing the ON time during a single cycle. For a normally open type suction control valve, making the duty ratio smaller increases the intake amount and, conversely, making the duty value larger decreases the intake amount.
