Description
DLLA150P858 belongs to the high-pressure common rail P-series extended needle-type fuel injector, which is a core precision component of the diesel common rail injection system. It adopts a stepped extended needle body forming design, which distinguishes it from the ordinary short-type fuel injectors. It precisely fits the corresponding specifications of common rail fuel injector assemblies and is used to replace worn-out, dripping, or poorly atomized components.
Material and exclusive processing technology
Alloy steel base material
The entire body is formed by a single piece of high wear-resistant alloy steel through cutting, combined with a constant temperature heat treatment process, enhancing the overall hardness. It can withstand the high-temperature and high-pressure conditions of the engine for a long time, resist the erosion of diesel media, and slow down the rate of component wear.
Stair-step extended needle body technology
Exclusive multi-level stepped needle body design, precise positioning, and during assembly, it fits the internal cavity of the fuel injector; the front end is finely ground with micro holes, with consistent hole diameters and spray angles, ensuring uniform fuel spraying.
Fine end face sharp tip processing
The front sharp tip is polished to a mirror finish, reducing the probability of carbon accumulation and lowering the probability of nozzle blockage after long-term use, maintaining a stable fuel supply state.
Product usage characteristics
Uniform atomization, optimizing cylinder combustion
The extended needle body combined with fine spray holes can disperse the high-pressure fuel, forming a fine oil mist, helping the gas and oil in the cylinder to fully mix, stabilizing the idle operation of the equipment, and reducing the accumulation of combustion residues.
Stable sealing under high pressure
Each fuel injector is completed with multiple rounds of high-pressure leakage and spraying tests upon leaving the factory, reducing dripping and pressure fluctuations under high-load conditions, and maintaining continuous and stable fuel supply.
Standard stepped assembly dimensions
The multi-level stepped needle body and the outer diameter of the head are strictly in accordance with the matching assembly standards, requiring no grinding or modification, and the disassembly and assembly process is simple, shortening the equipment maintenance time.
Flexible supply packaging
Each fuel injector is independently packaged for rust protection, preventing scratches and rust during transportation and storage; it can also be provided with neutral packaging without labels, supporting small sample purchases and large-scale bulk orders, and is suitable for cross-border export channels. Scope of Application
Suitable for the maintenance and replacement of fuel injectors for medium-sized freight trucks, small excavators, loaders, fixed diesel generators and other equipment that are equipped with high-pressure common rail systems.
