We are a manufacturer for diesel fuel parts, Such as Head Rotor, nozzle, plunger, feed pump, delivery valve, cam plate, repair kit and so on. Which are applied to Japanese car/truck, Euro truck, and Agricultural machines?

Suction Control Valves (SCV):
What a Technician is required to know about Fuel Rail Pressure Control on a Common Rail Diesel (CRD).
Maintaining the correct fuel pressure under all driving and load conditions is a requirement for efficient operation on a Common Rail Diesel (CRD). An ECU-operated suction control valve (SCV) or fuel metering control valve (FMCV) located on the back of the high-pressure supply pump is utilized for this purpose.

SCV valve function:
Function: Used to control the inlet diesel fuel which flows the diesel fuel pump. The SCV valve is an inverse proportional electromagnetic proportional valve controlled by the ECU. The ECU receives signals such as engine speed, water temperature, common rail pressure, and suction pressure, derives command current to the SCV valve, controls the opening of the SCV valve, and to achieve control diesel fuel into the diesel fuel pump. The purpose of the diesel fuel flow is to adjust the common rail pressure. Abnormal conditions will cause the engine output to drop down, or even stop.

SCV valve failure alarm
Common fault codes: P0628, P0628
Failure performance: The engine output drops, the engine won't catch or cutoff.
SCV valve role: used to control the inlet diesel flow of the engine diesel fuel pump.
