310-45204-B

Component Type: Common Rail Injector Control Valve (Valve Set / Control Element)

Original Equipment (OE) Manufacturer: Bosch

Bosch Part Number (OE/Repair Kit): F 00V C45 204

Alternative Part Number (Aftermarket): 310-45204-B

Primary Applicable Injector PNs (Bosch):

• 0445110520

• 0445110418 (Often compatible with or superseded by this valve)

Application Vehicle Manufacturers: Commonly used in vehicles utilizing the relevant Bosch injectors, such as FIAT, Iveco, Citroën, and Peugeot models (e.g., those with 2.3L and 3.0L Multijet engines).

System Compatibility: Bosch Common Rail System (CRS).

Function: The valve precisely regulates the flow of high-pressure fuel within the injector's control chamber. This action determines the opening and closing of the nozzle needle, enabling highly accurate metering of fuel (Pilot, Main, and Post injection events).

Operating Pressure Range: Designed and manufactured for reliable function in systems operating at pressures typically up to $\ge 1600$ bar.

Required Service Procedure: Replacement of this component is a precision repair that requires specialized Common Rail tooling and mandatory calibration/testing (including shimming) to determine the new IMA/QR coding for the reconditioned injector.

Material: High-precision, hardened steel alloy construction for resistance to wear, cavitation, and high-pressure fatigue.

Note: PN 310-45204-B is a cross-referenced component corresponding to the Bosch OE specification F 00V C45 204.
