Bosch original 4-series SC701 Series Diesel Fuel Injector 0414701082, Fuel Injector Nozzle, Injector Repair Kit, Cross Reference 1440579, for Auto Parts, Construction Machinery original new injector

Engineered for Scania HPI/PDE diesel fuel systems, the Bosch 0414701082 Unit Injector is an original heavy-duty fuel injection component manufactured to Bosch OEM specifications. This complete PDE unit injector assembly integrates high-pressure fuel generation and injection within a single unit, serving Scania DC12, DSC12, and DT12 engines across 4-Series, P-Series, G-Series, R-Series, and T-Series trucks, as well as bus chassis, marine power units, and industrial power applications.

Unlike conventional common rail systems, each injector contains an integrated high-pressure pumping element mechanically actuated by the engine camshaft. Under ECU command, the solenoid valve controls the precise fuel quantity while the multi-hole nozzle ensures optimized atomization. The result is higher injection pressure, superior combustion efficiency, better fuel economy, lower smoke emissions, improved cold starting, and stronger torque performance—critical advantages for Euro III and Euro IV heavy-duty operations.

Built with industrial-grade hardened steel and a precision-machined nozzle assembly, the 0414701082 delivers OEM-calibrated fuel delivery, excellent wear resistance, and extended service life under heavy loads. It cross-references Bosch numbers 0414701019 and 0414701027, exchange units 0986441015 and 0986441115, and Scania OEM references 1440579 and 0574393, simplifying sourcing for distributors, rebuilders, and fleet maintenance providers serving the transportation, construction, mining, marine, and power generation sectors.
