Engineered as a direct-fit OEM replacement component for Volvo D12 series diesel platforms, the BOSCH 1548475 electronic unit injector (EUI/UIS) is a factory-spec fuel injection solution for heavy-duty diesel equipment. It is fully compatible with Volvo D12A, D12B, D12C and D12D engines, and fits verified applications including Volvo FH12, FM12, NH12 trucks, B12 buses, Volvo construction equipment and industrial power units. It aligns with a full set of verified OE and cross-reference numbers to simplify part matching for global supply chains.
Built with integrated fuel pressurization and injection functionality, this injector operates in sync with the engine ECU to execute precise fuel metering commands. Its solenoid-actuated internal plunger generates consistent high pressure, while precision nozzle holes atomize fuel into fine mist for complete, efficient combustion. This design delivers measurable operational benefits including optimized fuel economy, reduced exhaust emissions, enhanced cold-start performance, stable power delivery and reliable service life under demanding heavy-duty operating conditions, in full compliance with Bosch OEM manufacturing standards.
This injector is tailored for B2B customers across the diesel injection ecosystem, including parts distributors, engine rebuilders, fuel injection specialists, fleet maintenance providers and aftermarket wholesalers. It supports use cases spanning long-haul transportation, construction, mining, industrial power generation and marine auxiliary power systems. Following OEM torque specifications during installation and adhering to routine maintenance rules (regular filter replacement, fuel contamination prevention) maximizes long-term performance stability.
