Bosch original 0414702019-007 common rail fuel injectors 3835257 automotive replacement for compatible parts designed for vehicle use, for heavy duty diesel engine application original new injector

The Bosch 0414702019-007 (0 414 702 019) is a genuine OEM diesel unit injector from the Bosch 702 Series, developed on proven UIS/PDE technology for heavy-duty diesel platforms. Designed as a single integrated assembly mounted directly in the cylinder head, it combines fuel pressurization and injection in one unit, delivering precise fuel metering for Volvo D12 Series engines, including D12D340, D12D380, D12D420, and D12D460, as well as 12.1L Euro 2 and Euro 3 diesel applications.

In operation, a camshaft-driven plunger mechanically builds injection pressure; once the calibrated opening pressure is reached, the injector needle lifts and fuel is atomized through the precision DLLA152P932 nozzle (0433171621) into the combustion chamber, with the injector closing immediately after each injection event. Factory calibration, high-pressure performance, precision fuel metering, and robust Bosch engineering support optimized combustion efficiency, reduced fuel consumption, lower emissions, and extended service life under demanding operating conditions.

This unit injector is widely used in Volvo FH12 and FM12 trucks and FH/FM series vehicles, as well as generator sets, mining equipment, construction machinery, agricultural equipment, industrial engines, marine equipment, and power generation units. Cross reference numbers include 0986441111, 0986441011, 8113895, 20440412, 5237196, and 3183496. For dependable performance, install with new sealing washers, follow Volvo torque specifications, keep the installation contamination-free, use clean diesel fuel, and replace fuel filters regularly.
