Fuel Injector Nozzle DLLA154PN0171

The Fuel Injector Nozzle DLLA154PN0171 is a precision diesel injection component designed for medium- to heavy-duty diesel engines, commonly used in commercial vehicles and industrial equipment. It features a 5-hole spray pattern with a nominal orifice diameter of 0.17 mm, manufactured from hardened stainless steel to withstand high-pressure fuel environments. The nozzle body is machined to exact tolerances of ±0.002 mm and conforms to the common rail injection standards defined by ISO 14374-1. This part is compatible with engine models requiring the OEM code 9 432 610 306 and replaces original equipment from Bosch, Denso, and Delphi systems.

The nozzle is fabricated from AISI 420 stainless steel with a surface hardness of 52-58 HRC, ensuring resistance to erosion and carbon buildup under continuous high-temperature operation. Typical industry standards for this nozzle type include a maximum tip temperature of 450°C and a fuel flow rate tolerance of ±3% at 1200 bar. The internal channel geometry is optimized for laminar flow, reducing cavitation risk. While the supplier does not specify surface coating, standard practice in the industry includes a nitride finish for improved wear resistance, though this may vary by batch.

This component is primarily sourced by diesel engine rebuilders, aftermarket distributors, and fleet maintenance operators across Southeast Asia, the Middle East, and Eastern Europe. Buyers typically order in quantities of 50 to 500 units per shipment, packaged in anti-static foam inserts within sealed cardboard boxes. Trade terms are commonly FOB Xiamen or CIF destination port, with lead times averaging 15 to 25 days after deposit. Buyers should verify nozzle flow calibration data and spray pattern certification prior to bulk purchase.

China Balin Power Co., Ltd. operates from Hualin Industrial Zone in Putian, Fujian, and specializes in the manufacturing of diesel fuel injection components. The company has been producing injector nozzles, plungers, and control valves for over a decade, with a focus on replacement parts for European and Japanese engine platforms. Their production facility includes CNC machining and ultrasonic cleaning lines, but the supplier's profile does not confirm ISO certification, third-party testing, or export volume data.

The supplier responds to inquiries with low frequency and has no verified trade history displayed on the platform. Their listing includes a range of part numbers matching known OEM equivalents, suggesting they source or replicate existing designs rather than develop proprietary components. There is no mention of in-house R&D, quality control labs, or client testimonials. Buyers should treat this as a direct manufacturer of generic injection parts, not an OEM supplier.
