Fuel Injector Nozzle 105015-5330, DLLA154SN533

The Fuel Injector Nozzle 105015-5330, also known by its stamping code DLLA154SN533, is a direct replacement for Mitsubishi 6D22T diesel engines. It weighs 0.05 kg per unit and is designed to operate under high-pressure fuel systems typical of industrial and marine diesel applications. This nozzle is manufactured as an aftermarket component, matching the original equipment dimensions and spray pattern to ensure compatibility with OEM fuel systems.

The nozzle body is machined from high-strength alloy steel with a hardened tip to resist erosion from diesel fuel and particulate contamination. The spray hole diameter and number are engineered to replicate the factory specification, with a typical spray angle of 140 degrees and a nominal orifice size of 0.18 mm. These are standard values for diesel nozzle designs in this class, though exact tolerances are verified through flow bench testing. The surface finish on the needle and seat meets industry norms for sealing integrity under 1800 bar operating pressure.

This nozzle is purchased by diesel engine rebuilders, marine maintenance contractors, and heavy equipment repair shops servicing Mitsubishi 6D22T engines in mining, agriculture, and shipping sectors. Units are packed individually in anti-static blister packs with part number labels. Bulk orders are shipped in cartons of 50 units. Lead time for stock items is typically 7 to 14 days from Fujian port, with FOB terms standard. Buyers should confirm compatibility with engine serial numbers before ordering.
