SCV (suction control valve)
By regulating the amount of fuel supplied to the plunger (4), the SCV (8) controls the pressure of fuel in the rail.
The SCV uses a linear solenoid valve and the fuel flow is controlled by controlling how long the SCV is energized by
the ECU.
There are two types of SCV valve, the fail-open type (max flow with no power) and the fail-closed type (min flow
with no power) and the engine uses a fail-open SCV.
When power flows to the SCV (8), the actuator inside moves according to the duty ratio, pressing on the cylinder
(7) and altering the flow of fuel corresponding to the size of the cylinder opening and establishing the appropriate
amount.
1) Fail-open type
With no power to the solenoid, the cylinder is returned via spring force and the valve opens wide, supplying a large
quantity of fuel to the plunger.
When the solenoid is energized, the armature presses on the cylinder, compressing the spring and reducing the
quantity of fuel supplied. The solenoid turns ON & OFF according to the duty ratio. The quantity of fuel supplied to
the plunger is in proportion to the size of the cylinder opening.
2) Duty ratio control
The engine's ECU outputs a waveform signal for a set interval. The current amperage is the average amperage
of the average current differential. When this average value rises, the size of the valve opening is reduced, and
conversely, when it drops, the valve opens wider.
3) When the SCV operates for a short time
The average current to the solenoid is low, so the cylinder is returned via spring force and the valve opens wide,
supplying a large quantity of fuel to the plunger.
4) When the SCV operates for a long time
The average current to the solenoid is high, so the armature presses on the cylinder, compressing the spring,
closing the valve opening and supplying a smaller quantity of fuel to the plunger.
