Bosch original 0414701086 Common Rail Diesel Fuel Injector for Truck and Construction Machinery Replacement for OEM, for heavy duty diesel engine application original new injector

Precision-engineered for verified Scania heavy-duty diesel platforms, the Bosch 0414701086 is a cylinder-specific electronic unit injector (EUI) categorized under Bosch D12 catalog series. Classified as a UIS pump-nozzle or Scania PDE injector, this assembly integrates a high-pressure pumping element, ECU-controlled electromagnetic valve, precision nozzle, and injector body into one compact cylinder-head-mounted unit. Unlike conventional common-rail injectors, it requires no external high-pressure fuel rail, with each unit serving a single engine cylinder.

During operation, a camshaft-driven mechanism actuates the injector plunger, while the engine control unit energizes the solenoid valve at calibrated timing to build pressure and deliver a precise fuel dose directly into the combustion chamber. Verified data confirms fitment for Scania DC13 and DC9 PDE engine families; listings referencing DC13.140 and DC9.50 variants require engine serial number cross-checks prior to shipment. Fitment must also be confirmed via Bosch and Scania part numbers, injector appearance, connector design, and official Scania parts catalogs to avoid application errors.

This injector supports professional heavy-duty diesel use cases including defective unit replacement, engine rebuilding, fuel system repair, fleet maintenance, and workshop service. It is not a universal interchange part, and related Bosch numbers from third-party listings are not validated as direct replacements due to potential differences in calibration, nozzle configuration, and engine mapping. Installation must be performed by a qualified heavy-duty diesel technician following engine-specific procedures with proper adjustment tools to ensure reliable operation.
