Bosch original Diesel Fuel Injector Pump 1548472, for heavy duty diesel engine application, Cross Reference 1420379, OEM Replacement for Excavator DC12 DC16 original new injector

The BOSCH 1548472 Electronic Unit Injector is an OEM-specification fuel injection component engineered for Scania DC16 series heavy-duty diesel engines. As a highly sought-after part across the global diesel aftermarket, remanufacturing sector, fleet maintenance networks and injection system supply chains, it supports a broad range of industries including commercial transportation, mining, construction, marine propulsion and power generation. It fits specific DC16 engine variants (DC16.06, DC16.09, DC16.19) across industrial, marine and heavy-duty scenarios, with full cross-reference compatibility to common replacement part numbers.
Built with integrated Electronic Unit Injector (EUI) technology, this part combines fuel pressurization, metering and injection functions in one compact unit. Its camshaft-driven plunger generates high injection pressure, while the ECU controls injection timing via a solenoid valve to deliver precise fuel atomization into combustion chambers. This design drives optimized combustion efficiency, lower fuel consumption, reduced smoke emissions, increased engine power and enhanced durability. Manufactured to OEM standards with precision machining, corrosion-resistant components and factory calibration, it supports reliable heavy-duty operation.
This brand-new injector comes with a 12-month warranty and stable global aftermarket supply for B2B buyers including fleet operators, repair workshops and parts distributors. Installation guidance includes cleaning injector bores, using new sealing components, conducting leak tests and following Scania workshop manual specifications. Routine maintenance recommendations include regular fuel filter replacement, use of clean diesel, water contamination prevention and periodic ECU diagnostics to minimize unplanned downtime.
