Suction Control Valve (SCV)

The suction control valve (SCV) is a proportional control valve that adjusts the amount of fuel delivered from the

fuel pump to achieve the fuel pressure requested by the engine, has a function of delivering to the pressurizing part,

and is made up of a piston (5), cylinder (6), armature (3), and solenoid (2) etc.

The SCV is a linear solenoid type electromagnetic valve and the engine ECU controls the time the solenoid is

electrified (duty ratio control). When current flows through the solenoid, the armature moves based on the duty ratio

and pushes on the cylinder and fuel flow changes based on position of the cylinder enabling suitable fuel flow.

NOTE

• Since the suction control valve (SCV) has not been adopted as a part, replace the supply pump when SCV

is needed to replace.

• Linear solenoid type: when voltage is applied to the coil, the moveable core moves linearly in proportion

to the voltage based on the magnetic force

Pressurizing Part (Pump Body)

The pressurizing part (pump body) applies pressure

to the fuel supplied from the suction control valve, has a

function of supplying fuel to the rail, and is made up of an

IO valve (1), plunger (5), plunger barrel (6), spring (7),

tappet (8), and pump housing etc.

The engine side fuel camshaft (9) rotates and during

the  lowering  stroke,  the  spring  cause  the  plunger  to

lower. An optimal amount of fuel adjusted by the suction

control valve is suctioned through the IO valve and into

the plunger chamber (4).

Rotation continues and during the lift stroke of the

cam the plunger rises, pressurizes the fuel, and supplies

it through the IO valve to the rail.
