This high-pressure electronically controlled nozzle assembly (standard part code: 3609962, common interchangeable and cross-referenced part numbers include 3609962PX, 3411767, 3087557, etc.) is precision-engineered for heavy-duty commercial trucks, construction machinery, and large-displacement diesel power systems (such as N14, NT855 series diesel engines). As the core control and execution component of the fuel supply and combustion control system, it bears the crucial responsibility of precisely metering and atomizing high-pressure diesel fuel into ultra-fine particles within microseconds. It is widely installed in long-haul trucks, large-tonnage engineering dump trucks, special excavation equipment, and standby diesel generator sets.
Adhering to the R&D standard of "ultra-fine particle high-pressure injection, millisecond-level precise response," the internal needle valve assembly and armature valve core are both subjected to ultra-high precision grinding and ultra-low friction polishing. The surface is covered with a high-density anti-coking hardened coating, which can effectively resist early erosion caused by impurities in inferior diesel fuel. After the equipment is upgraded, drivers and machine operators will experience noticeable performance improvements: cold starts are quick and smooth, and the severe shaking and vibration at low idling speeds are completely eliminated; under heavy loads climbing steep slopes or high-intensity continuous tunneling conditions, the accelerator pedal feedback is crisp and smooth, providing a continuous and stable supply of power, while significantly reducing exhaust smoke and resulting in superior fuel economy for the vehicle and machinery.
Direct supply from our self-operated modern production base.
Traditional OEM procurement models involve complex processes that can lead to excessive tolerances in parts, uneven fuel supply to cylinders, and high-pressure leaks, while also significantly increasing procurement costs.
Our self-built standardized production base implements precision manufacturing throughout the entire process, eliminating layers of intermediaries and ensuring consistent injection height across cylinders. This reduces maintenance costs and provides a robust and reliable power guarantee for the long-term operation of the equipment.
100% fully simulated digital bench rigorous quality inspection.
Addressing quality issues such as delayed solenoid valve response, internal pressure leakage, and needle valve jamming common with low-quality parts, leading to unstable power after installation and wasted time and money on repeated disassembly and debugging.
Each injector undergoes fully automated testing before leaving the factory. Under simulated high temperature and ultra-high pressure conditions, the injection volume and return oil sealing are precisely calibrated for different pressure ranges, ensuring immediate usability after installation and significantly saving time and costs associated with equipment disassembly and debugging.
A large, readily available inventory and rapid warehousing and distribution.
Addressing the costly delays and lost work time caused by fuel system failures affecting commercial vehicles and construction machinery, resulting in downtime and material shortages.
The warehousing center maintains a sufficient stock of best-selling specifications year-round. Orders are responded to quickly, with priority packing and shipping within 24-48 hours, significantly shortening the logistics and delivery cycle. This helps fleets and owners quickly restore equipment availability and effectively avoids downtime losses.
Made of special hardened alloy wear-resistant and corrosion-resistant material.
Addressing the issue of premature wear and valve core seizure caused by variations in diesel lubricity and sulfur content across different regions.
The core valve assembly utilizes high-strength special bearing steel and undergoes a surface anti-corrosion hardening treatment, significantly improving fatigue resistance and wear resistance. It maintains stable performance even under harsh environments and prolonged high-load operation, avoiding the additional costs associated with frequent disassembly and repairs.

Long-Distance Logistics and Mountainous Steep Slope Climbing: In cross-regional logistics transportation, trucks fully loaded with heavy cargo face long-term high-speed cruising and continuous steep slope climbing. By replacing their fuel injectors with this high-pressure injector, drivers can clearly feel that the vehicle's upshifts are crisper, the power output is full and does not diminish when the accelerator is pressed, and the diesel fuel is fully combusted, improving climbing torque while effectively reducing overall fuel consumption.
Construction Engineering and Continuous Operation of Large Heavy-Duty Machinery: In construction sites with high dust and harsh terrain, heavy equipment frequently operates under heavy loads. This injector, with its microsecond-level electronic control response and ultra-high-pressure atomization capability, ensures that the engine can still output continuous high torque even when facing sudden fluctuations in engine speed. The combined action is smooth and continuous, completely avoiding engine stalling and misfires, ensuring efficient progress in construction.
Q: Can I use it directly after receiving the product? Do I need to enter a correction code?
A: Each injector has a unique flow correction code (IMA code) generated during factory testing. It is recommended to use a diagnostic tool to flash the correction code into the engine ECU after installation to achieve optimal fuel efficiency and smoothness.
Q: What is the inventory and delivery time for bulk purchases?
A: We have our own factory and large warehouse, and maintain a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can also be quickly arranged for production line scheduling.
Q: How do you guarantee the quality and performance of the product before it leaves the factory?
A: All injectors undergo assembly in a Class 100 cleanroom and 100% full-condition bench testing, covering key indicators such as sealing, pre-injection volume, full-load injection volume, and return oil volume. These stringent testing standards ensure that they are of superior quality from the outset.
Q: How long is the warranty period? What are the after-sales service details?
A: We offer a 12-month warranty period. If a performance failure occurs within the warranty period due to non-human factors, we provide rapid replacement or after-sales technical support to ensure your peace of mind.
