Bosch original Fuel Injector Unit 2045066 Replacement for OEM, for heavy duty diesel engine application, Cross Reference 02112706, D7D Engine, EC290 EC240 Excavator original new injector

Engineered for modern heavy-duty diesel engines, the BOSCH 2045066 Common Rail Diesel Fuel Injector (Bosch OE 0445120041) is an original, OEM-quality high-pressure injection component from the Bosch 750 Series CRIN1-14/16 injector family. Manufactured to Bosch original equipment specifications, it delivers precise fuel atomization, optimized combustion efficiency, reduced emissions and improved engine performance. The injector is widely used in Doosan and Daewoo DV11, DV11T, DV11TI, DE12T and DE12TI engines powering excavators, wheel loaders, generator sets, heavy-duty trucks, buses and marine propulsion systems.
Working within a high-pressure common rail system exceeding 1600–2000 bar, the injector performs ECU-controlled injection events: the solenoid valve activates, control chamber pressure changes, the needle lifts, and fuel atomizes through precision nozzle holes. Multiple injections per cycle improve fuel economy, lower emissions, reduce engine noise and increase power output. Micron-level nozzle tolerances ensure precise fuel metering, while factory-tested flow and response characteristics guarantee OEM-calibrated performance in demanding duty cycles.
Constructed from specialized hardened, corrosion-resistant steel, the injector is built for extended service life in construction, mining, marine and power-generation environments. Recommended maintenance includes inspection every 50,000 km, fuel filter replacement every 20,000 km and injector testing every 100,000 km, using Ultra Low Sulfur Diesel (ISO 8217 compliant). Supported by worldwide Bosch diesel service centers, the BOSCH 2045066 offers global serviceability for fleet maintenance companies, engine rebuilders and fuel system repair workshops.
