Bosch original Electronic Control Unit Pump Fuel Injector, replacement for OEM, engine DC12, heavy-duty truck application, part number 1440578 original new injector

Engineered for Volvo D12 series heavy-duty diesel platforms, the BOSCH 1440578 Electronic Unit Injector (EUI) is an original new, OEM-quality fuel injection component built to BOSCH manufacturing standards. Using advanced Electronic Unit Injection technology, the injector responds to precise ECU signals, activating a high-pressure fuel chamber that lifts the needle and atomizes fuel through precision nozzle holes. This delivers accurate fuel metering, optimized injection timing, and superior atomization for improved combustion, better fuel economy, increased horsepower, and reduced emissions.

As a direct OEM replacement, it cross-references Volvo 20440388, VOE20440388, 20524635, 21120146, 8113408, 85000063, 85000071, 85006071, 85013162, 21586284, 3803654, BEBE4C01001, BEBE4C01101, EX631015, and EX631015R. The injector fits Volvo D12A, D12C, and D12D engines, including D12C340, D12C380, D12C420, D12D420, D12D460, and D12D500 variants, plus marine, industrial, and generator configurations.

Built to BOSCH OEM manufacturing standards, the 1440578 features heavy-duty construction, a stable injection pattern, long service life, and a 12-month warranty, with global supply available. Installation follows Volvo torque specifications with new seals, while clean diesel and regular filter changes maximize durability. This makes it an ideal sourcing choice for distributors, wholesalers, engine rebuilders, fleet maintenance providers, and diesel injection specialists worldwide.
