Bosch original Diesel Common Rail Fuel Injector 0445110777 for D1803 V2403 Engine, for heavy duty diesel engine application, Crawler Excavator Replacement for OEM original new injector

Built to Bosch’s stringent OEM manufacturing specifications, the 0445110777 common rail diesel fuel injector is a precision-engineered electronic solenoid component designed for modern high-pressure common rail diesel injection systems. It is compatible with Cummins ISF3.8, ISBe4.5, ISDe4.5, ISDe6.7, QSB series engines and various industrial diesel platforms, delivering consistent performance even under heavy-duty operating conditions. Compliant with Euro III to Euro V emission standards, it balances optimized fuel economy, reliable power output and regulatory compliance for fleet and industrial operators.
Controlled by the engine ECU, the injector activates via a fast-response solenoid to open the precision-machined needle valve at exact timing, supporting pilot, main and post multi-stage injection events. It enables ultra-precise fuel metering and superior atomization to maximize combustion efficiency, reduce particulate and NOx emissions, enhance cold start performance and improve engine responsiveness. Industrial-grade structural design delivers high-pressure fuel delivery capacity, corrosion resistance and long service life for demanding work scenarios.
This injector fits a wide range of equipment including light, medium and heavy duty trucks, buses, construction machinery, agricultural equipment, generator sets and stationary industrial engines, serving commercial transportation, construction, agriculture, power generation and marine auxiliary sectors. It comes with a 12-month warranty, with neutral or customized packaging options available. Professional installation following torque specifications and regular maintenance with high-quality diesel and OEM-grade fuel filters are recommended to sustain optimal performance.
