Bosch original 0414702023 Common Rail Fuel Injector for Penta D12, D12D, Replacement for OEM 3829644, Bionic Exoskeleton Liquid Displacement Propulsion diesel Engine original new injector

Engineered for Volvo and Volvo Penta D12 heavy-duty diesel platforms, the original BOSCH 0414702023 (0 414 702 023) unit injector is part of the Bosch 702 Series Unit Injector System (UIS / PDE pump-nozzle) family. In this design, fuel metering, high-pressure generation, injection control, and nozzle atomization are integrated into one compact assembly. Driven by the engine camshaft, the injector plunger compresses fuel inside the injector body, and the nozzle needle opens at the calibrated point, delivering finely atomized diesel directly into the combustion chamber.

This injector directly replaces Volvo Penta OE number 3829644 (VOE3829644 / VOA3829644) and is cross-referenced with Bosch 0414702013, Bosch exchange number 0986441109, 0986441006, nozzle reference DLLA152P1077, and sealing kit F00VX99995. Confirmed engine applications include Volvo Penta D12 TAD1240GE, TAD1242GE, and TAD1240VE, plus related Volvo D12 / D12D engines in marine, generator set, and industrial power unit service. Typical buyers include diesel repair workshops, fleet maintenance companies, marine engine service centers, and global diesel parts distributors.

Built to Bosch OE engineering standards, the 0414702023 delivers precision atomization, high injection pressure capability, accurate fuel metering, and heavy-duty durability. Before ordering, confirm the application by injector number, engine serial number, and Volvo Penta EPC data. During service, replace fuel filters, O-rings, and seals, follow OEM torque specifications, and verify performance with injector calibration and leakage checks.
