0928400617 — Bosch Fuel Metering / Pressure Regulator Valve (SCV)

Precision metering for stable rail pressure - ideal for Cummins, MAN, DAF and other common-rail diesel platforms

0928400617 (Bosch 0 928 400 617) is a compact but mission-critical suction/pressure control valve (SCV) used in the low-pressure metering stage of many Bosch common-rail pump systems. By regulating the quantity of fuel delivered into the high-pressure pump, this valve directly influences rail build-up speed, multi-shot timing accuracy and overall engine response - so a small fault here can create big drivability and emissions issues.

 

 

Modern diesel systems depend on precise metering before the high-pressure pump. The 0928400617 modulates inlet flow via an electrically actuated solenoid (pulse-width modulated control), allowing the ECU to stabilise rail pressure under varying loads and engine speeds. This means improved cold starts, reduced transient smoke, and more consistent DPF / aftertreatment behaviour when the valve and its control strategy are functioning correctly.

 

 

This SCV appears across a broad range of applications - commonly referenced on Cummins ISB / ISBe / ISDe families and in truck platforms from MAN, DAF and regional OEMs (Shaanxi, Dongfeng, etc.). Sellers and catalogues also list interchange numbers such as 4903282 / 4902916 / 51125050027 / 5257595, so always confirm fitment using pump and engine serials before ordering.

 

 

Slow or irregular rail pressure rise during cranking (hard starts).

Erratic idle, loss of low-end torque, or hesitation under acceleration.

Intermittent rail pressure DTCs and failed DPF regeneration attempts.
If you see these, the valve should be included in your bench diagnostic workflow; it's often more economical to replace a failing metering valve than to chase collateral damage in pumps or injectors.

 

0 928 400 617 (0928400617).

Suction/pressure metering control valve (fuel-cooled solenoid).

PWM actuation (typical frequency ~1 kHz) to vary valve opening and thereby control inlet pressure/flow.

When de-energised the internal spring sets a baseline opening; with coil actuation the magnetic force modulates the opening to increase rail pressure.

 

 

Always work in a contamination-controlled area when handling fuel-system components. High-pressure diesel systems are unforgiving to particles - even small debris can cause injector scoring and pump damage. Follow OEM torque sequences and test procedures, and keep bench reports attached to serviced units for traceability and warranty support.
