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

The Bosch 0414701086 (0 414 701 086) is an electronic unit injector engineered for heavy-duty diesel engines equipped with a PDE / UIS unit-injection system. Unlike a conventional common-rail injector, this assembly integrates the high-pressure pumping element, ECU-controlled electromagnetic valve, nozzle and injector body into a single cylinder-head-mounted component. During operation, a camshaft-driven mechanism actuates the plunger while the engine control unit energizes the solenoid at the calculated moment, delivering precisely timed and metered fuel directly into the combustion chamber without an external high-pressure rail.

Verified application data links this unit to Scania DC13 and DC9 PDE engine families, cross-referenced to Scania OE 2599428 and the earlier, now-obsolete 2559308; market listings also cite DC13.140 and DC9.50 variants. Because calibration, nozzle configuration, connector design and engine mapping can differ across the wider injector family, related Bosch numbers such as 0414701077, 0414701076, 0414701073, 0414701072 and 0414701051 must not be treated as direct interchanges. Fitment should always be confirmed against the Bosch number, Scania OE number, engine serial number, injector appearance, electrical connector and the applicable Scania parts catalog.

Supplied for the global truck and industrial aftermarket, this injector suits engine rebuilding, fuel-system repair, fleet maintenance and diesel workshop replacement of a confirmed defective unit. Installation should be performed by a qualified heavy-duty diesel technician using the correct adjustment tools and the engine-specific workshop procedure.
