Bosch original Fuel Injector 21160093 Replacement for OEM Components, for heavy duty diesel engine application, Compatible with 20440409 for Large Engine original new injector

Engineered for heavy-duty industrial, marine and power generation applications, the Bosch 702 Series Unit Injector 21160093 (Bosch 0414702025 / 0 414 702 025) is a brand-new, OEM-quality diesel fuel injector. Based on Bosch PDE / UIS (Unit Injector System) technology, it integrates the fuel pump and injection nozzle into a single assembly, eliminating high-pressure fuel lines and enabling precise, electronically controlled injection directly at each cylinder. A 12-month warranty is included.

As a direct OEM replacement for Volvo Penta OE 21160093, it cross-references Volvo 3801293, Bosch 0414702016 (0 414 702 016), PDE numbers 702025 and 702016, Lucas reman number LDFC0176, and exchange numbers 21160093EX and 3801293RX. The injector fits Volvo Penta D12D, D12 Marine, TAD1240GE, TAD1240VE, TAD1241GE, TAD1241VE, TAD1242GE and TAD1242VE engines, and is widely applied in marine propulsion systems, diesel generator sets, industrial power plants, construction machinery, mining equipment, oil & gas power units and agricultural machinery.

In operation, a camshaft-driven plunger builds injection pressure while the ECU-signaled solenoid precisely controls timing, atomizing fuel into ultra-fine particles for optimized combustion. This delivers superior fuel atomization, reduced fuel consumption, lower exhaust emissions, improved engine performance and long service life. For reliable operation, use clean diesel fuel, replace fuel filters regularly, monitor fuel pressure, prevent water contamination, inspect electrical connectors and perform annual injector diagnostics; depending on ECU configuration, injector coding verification may be required after installation.
