Engineered for the Scania DC12 / D12 heavy-duty diesel platform, the BOSCH 0414701044 (0 414 701 044) is an original unit injector covering DC12.06 and DC12.17 12.0L Euro 3 engine codes. It is commonly cross-referenced with Bosch 0414701066 (0 414 701 066) and Scania OE number 1805344, and diesel parts channels list this injector family for Scania G380, G420, P380, P420 and R420 trucks, giving distributors and fleet buyers a precise OE-matching replacement option.

As a pump-nozzle unit, the injector integrates fuel pressurization and injection delivery inside one body. The camshaft mechanically actuates the plunger; when injection pressure reaches the designed threshold, the nozzle needle opens and fuel is atomized into the combustion chamber, then closes rapidly to prevent leakage and maintain combustion timing. Nozzle reference 0433171575 / DLLA150P847 supports accurate spray atomization, while quality control covers flow testing, leak testing and spray pattern testing. New, remanufactured and reconditioned condition options are available.

For dependable service life, clean the fuel system, replace the fuel filter, renew all sealing washers and O-rings and follow Scania OEM torque specifications, with professional diagnostic calibration after installation. Clean diesel, regular filter changes and draining the water separator help prevent hard starting, rough idle, black or white smoke, power loss and high fuel consumption. The injector suits commercial truck repair, fleet maintenance and the diesel injection service market.
