Import Bmw Nozzle Dn0pd650 Cat Fuel Nozzles — Buy in wholesale FOB from Supplier in China

The DN0PD650 is a diesel fuel injector nozzle engineered for direct-injection systems in BMW passenger car engines and Caterpillar (CAT) off-highway and industrial diesel applications. This specific type, designated DN0PD, belongs to the P-type nozzle family with a cylindrical seat and guided needle, delivering fuel at pressures typical of legacy mechanical pump-line-nozzle systems. The nozzle body is manufactured from hardened alloy steel with precision-ground orifices to ensure consistent spray patterns and atomisation critical for combustion efficiency. China-Lutong Parts Plant lists this component from their Putian facility in Fujian Province, China, with no stated minimum order quantity or lead time in the available data.

Material specification for DN0PD-series nozzles typically involves 18CrNi8 or equivalent case-hardening steel for the nozzle body, with a needle valve paired to micron-level tolerances to prevent leakage and ensure rapid closure against high cylinder pressures. The spray holes, usually between 0.18 mm and 0.35 mm in diameter depending on engine displacement and power output, are finished by abrasive flow machining to achieve the required flow coefficient and spray angle. Standard industry practice requires that nozzle sets be kept as matched pairs, body and needle, to maintain hydraulic performance; mixing components from different production batches risks variation in opening pressure and fuel delivery quantity. Typical operating conditions see fuel temperatures up to 80 degrees Celsius and injection pressures in the range of 150-200 bar for mechanical systems of this generation.

Applications span BMW diesel passenger vehicles equipped with M21, M41, or M51 engines where the DN0PD650 cross-reference applies, plus CAT small-displacement industrial engines requiring this nozzle profile. Buyers include independent diesel repair workshops, engine rebuilders, and aftermarket parts distributors serving European and North American markets. The component is typically supplied as an individual nozzle or in engine sets of four or six units with shim adjustment washers. Packaging is usually protective plastic or blister packs with corrosion inhibitor, though the exact configuration from this supplier should be confirmed. Importers should verify whether China-Lutong offers the nozzle with or without the calibration shim set, as shimming is essential for correct opening pressure adjustment on installation.

China-Lutong Parts Plant operates from Dufeng Industrial Road in Hanjiang District, Putian, Fujian Province, China, a region with established manufacturing infrastructure for automotive fuel system components. The supplier is classified at the imported tier with a harbor trust designation, indicating profile data has been brought into the system without direct platform verification or transaction history. The response rate is recorded at 0.00 percent with zero average response hours, signalling that inbound buyer enquiries through this channel have not received tracked replies. No workforce size, annual revenue, factory square footage, or years in operation are stated in the profile.

The listing presents the DN0PD650 nozzle as a precision component for BMW and CAT diesel engines, with emphasis on wear resistance and compatibility. What is absent from the profile is equally notable: no ISO certification numbers, no stated quality management system, no listed OEM or tier-one customer references, and no disclosed production equipment such as Bosch or Zexel-licensed nozzle grinding lines. Buyers should conduct direct due diligence on manufacturing capability, gauge calibration records, and whether the supplier produces nozzles in-house or sources from sub-manufacturers. The address places the operation within Putian's industrial zone, but physical audit or third-party inspection is advisable given the lack of response data.
