Bosch original For Scania DC12 DC16 Diesel Engine Fuel Injector, compatible with multiple engine series, Excavator Diesel Fuel Unit Pump Injector 0414701077 Replacement for OEM original new injector

Engineered for demanding heavy-duty diesel applications, the Bosch 0414701077 is an original electronic unit injector developed on Bosch's proven UIS (Unit Injector System) and PDE (Pump-Nozzle Unit) technology platform. Built for the D12 engine series, it integrates the pumping element and injection nozzle into a single camshaft-actuated unit, delivering precise fuel metering, optimized combustion efficiency, faster engine response, reduced fuel consumption, and lower exhaust emissions.

During operation, the camshaft drives the injector plunger to build high fuel pressure, while the ECU-controlled solenoid valve precisely manages injection timing and duration. A multi-hole precision nozzle ensures superior fuel atomization, resulting in improved fuel economy, reduced smoke, reliable cold starts, and higher power output. Manufactured with micron-level machining and premium corrosion-resistant alloys, the injector delivers excellent thermal stability and long service life for high-mileage fleet operation, with every unit factory tested to Bosch original equipment standards.

Compatibility covers Volvo D12A, D12B, D12C and D12D variants, Scania DSC12, DSC1201 and DSC1202, MAN D2866 and D2876, plus industrial D12 generator and marine engines, serving heavy-duty trucks, construction machinery, mining equipment, marine propulsion, and power generation worldwide. The injector directly replaces 0414701076 and 0414701050 and cross-references OEM numbers 1943972, 1805346, 1455865, 1420384, 574373, and 574386.
