Bosch DLLA150P2386 Common Rail Injector Nozzle

The DLLA150P2386 is a high-pressure common rail diesel injector nozzle designed for Bosch 0445120357 and 0445120446 series injector assemblies. It features a 150-degree spray angle with 8 precision-drilled holes optimized for Weichai WD615 CRS EU4, WP10, and WP12 engine combustion chambers. Manufactured from high-speed steel to withstand injection pressures exceeding 1800 bar, the nozzle ensures precise fuel atomization and durability under heavy-duty cycles. The nozzle body dimensions measure approximately 60mm length by 15mm diameter. It serves as a direct replacement for Bosch OEM part number 0433172386 and Sinotruk OEM VG1034080002. This component is critical for maintaining emission compliance (Euro IV/V) and fuel efficiency in Sinotruk HOWO and HOWO A7 platforms. Installation requires professional calibration equipment to verify opening pressure and spray pattern.
