Engineered for demanding commercial operations, the Bosch 702 Series Unit Injector 20440412 is an original OEM diesel fuel injection component developed for Volvo D12D heavy-duty engine platforms. Based on Bosch Unit Injector System (UIS/PDE) technology, this electronically controlled injector combines the high-pressure pump and injection nozzle within a single assembly, eliminating the need for external high-pressure fuel lines. It is factory-matched to Volvo FH12 and FM12 trucks in Euro 2 and Euro 3 configurations, covering D12D340, D12D380, D12D420, and D12D460 12.1-liter engines.
In operation, the engine camshaft actuates the injector plunger to generate fuel pressure directly inside the injector body, while the ECU commands the solenoid valve to control injection timing and quantity with extreme accuracy. Diesel is delivered through the precision DLLA152P932 multi-hole nozzle (0433171621), producing ultra-fine atomization that mixes thoroughly with compressed air. The result is more complete combustion, higher injection pressure, improved torque output, lower fuel consumption, reduced emissions, and reliable cold-start performance. Hardened alloy steel internal components provide superior wear resistance and long service life under severe fleet conditions.
Manufactured to Bosch OEM standards, the 20440412 carries extensive cross references—including 0414702007, 0414702019, 0986441011, 0986441111, and Volvo OE numbers 8113895, 5237196, and 3183496—simplifying sourcing for distributors and fleet maintenance providers. It serves long-haul transport, logistics fleets, industrial power generation, and construction machinery across global OEM and aftermarket channels.
