Diesel Injector Nozzle Dlla143s1302

The Diesel Injector Nozzle Dlla143s1302 is a precision fuel delivery component designed for use in medium-duty diesel engines, commonly found in commercial vehicles and agricultural machinery. It features a 5-hole spray pattern with a nominal orifice diameter of 0.18 mm, constructed from hardened tool steel to withstand high-pressure fuel environments. The nozzle body is machined to exact tolerances of ±0.002 mm, ensuring consistent spray geometry and fuel atomization. This part is compatible with Bosch-style common rail and pump-line-nozzle systems used in Euro III and IV compliant engines.

The nozzle is manufactured using high-carbon chromium steel with a surface hardness of 58-62 HRC, typical for diesel injector nozzles in this class. The internal flow channels are honed to reduce friction and prevent carbon buildup, extending service life under continuous high-load operation. While the supplier does not specify a coating, standard industry practice for this part type includes a nickel-chromium plating to resist corrosion from sulfur-containing fuels. Variants may differ in nozzle length or tip geometry depending on engine model, but the Dlla143s1302 conforms to the standard Bosch 143-series design.

This injector nozzle is purchased by diesel engine rebuilders, fleet maintenance operators, and parts distributors across Southeast Asia, Africa, and Latin America. Buyers typically order in batches of 50 to 500 units, with packaging in sealed anti-corrosion bags inside cartons. Lead times are generally 15 to 25 days from order confirmation, and shipments are commonly sent via FOB Fuzhou port. Buyers should confirm compatibility with their engine model using the OEM part number before ordering, as similar nozzles may have subtle differences in spray angle or flow rate.

Chen Chen Diesel Parts Plant is a manufacturer based in Fuzhou, Fujian Province, China, specializing in diesel fuel injection components including nozzles, plungers, and delivery valves. The supplier is listed as an imported tier with harbor trust status, indicating verified export experience and logistics capability.
