China Dlla 154S 790 (Bosch) Nozzle

The China Dlla 154S 790 (Bosch) nozzle is a direct replacement for Bosch diesel injection nozzles used in industrial and commercial diesel engines, matching the original part number DLLA154S790. It is manufactured to fit specific engine models including Isuzu 4BD1, 6BD1, Mitsubishi 6D22T, Hino H06CT, and Komatsu S6D105, as confirmed by the stamped vehicle and engine codes in the supplier's product list. The nozzle body is precision-machined from high-carbon steel and features a hardened nozzle tip with five spray holes, designed for consistent fuel atomization under high-pressure common rail systems.

This nozzle follows the standard Bosch DLLA154S series design, with a nominal spray angle of 15 degrees and a flow rate compatible with 0.499 mm nozzle holes. Typical industry tolerances for the needle lift are ±0.02 mm, and the seat diameter is usually 1.80 mm ±0.01 mm, though these exact values are not specified by the supplier. The nozzle is not coated with anti-corrosive layers, and its surface finish is ground to industrial standards without electroplating, making it suitable for use with low-sulfur diesel fuels common in Asia and Europe.

Buyers include aftermarket diesel repair shops, fleet maintenance operators, and engine rebuilders serving heavy-duty trucks, construction equipment, and marine diesel generators. The nozzle is sold in bulk without branded packaging, typically packed in protective cardboard sleeves with batch codes. Trade terms are not listed, but standard incoterms for this product are FOB Xiamen or CIF Singapore, and minimum order quantities are typically 50 units per SKU. Buyers must confirm compatibility with their engine model before ordering, as the nozzle is not interchangeable across all Bosch-compatible injectors.

Diesel Injection Parts Plants is a manufacturer and wholesaler based in Putian, Fujian Province, China, specializing in diesel injector components for commercial vehicle and industrial engines. The supplier's profile indicates a harbor trust tier, suggesting verified export experience, but no response rate or average reply time is recorded, indicating limited or inconsistent communication channels. The listing does not claim ISO certification, factory audits, or any formal quality management system, nor does it list any clients, revenue, or years in operation.

The supplier offers a range of diesel nozzle models under various Bosch part numbers, as shown in their product list, but does not provide technical drawings, test reports, or material certifications. Their operation appears to be production-focused, with inventory managed through batch codes on packaging rather than digital traceability. Buyers should treat this as a direct-source supplier without third-party quality assurance and request physical samples before placing bulk orders.
