Bosch 0445120087 Fuel Injector Assembly

The Bosch 0445120087 is a solenoid-type common rail fuel injector designed for high-pressure direct injection diesel systems. It operates at a maximum system pressure of 1600 bar (160 MPa) and utilizes the DLLA142P1654 nozzle (OE 0433172015) for precise fuel atomization. The injector body is constructed from high-strength alloy steel to withstand cyclic combustion loads. It integrates a Bosch F00VC01543 / F00RJ01727 control valve for fast switching response. This assembly serves as a direct replacement for Weichai OEM part number 612630090008. Primary applications include Weichai WP10, WD10, and Deron series engines installed in Shacman Delong heavy-duty trucks such as the F3000 series. The injector is calibrated to meet Euro III / Euro IV emission standards. All units are bench-tested for opening pressure, leakage, and spray pattern conformity to Bosch technical specifications.
