Detailed Product Information
<Product Description> This high-pressure electronically controlled common rail injection assembly (standard part number: 3093415, common interchangeable and cross-referenced part numbers include 3093415PX, 3013892, 3027588, etc.) is specifically designed for heavy-duty diesel power systems (such as N14 and NT855 series large-displacement engines). It is the core control unit for achieving precise fuel metering and ultra-high pressure fine injection. The product is widely applicable to mining trucks, long-haul logistics trucks, engineering dump trucks, and high-load standby diesel generator sets.
This product adheres to the design philosophy of "ultra-fine particle high-pressure atomization and millisecond-level response control." The core needle valve assembly and control valve core are ground using micron-level geometric matching, and the surface is coated with a high-density anti-coking hardened coating, easily coping with the abrasion caused by impurities in inferior diesel fuel. After the equipment is upgraded, drivers and operators will experience a noticeable improvement in performance: ignition starts cleanly and crisply, and the severe vibrations at low idle speeds are completely eliminated; during heavy-load uphill climbing or continuous high-load operation, the accelerator pedal response is smooth and precise, providing a continuous and abundant power supply, and significantly reducing black smoke emissions, resulting in excellent overall fuel economy control.
Product Advantages
Direct manufacturing in a self-operated automated factory.
Problems Solved: Addresses the issues of complex traditional OEM procurement processes, which can lead to dimensional discrepancies in parts, uneven fuel supply to cylinders, and potential high-pressure leaks.
Value Brought: Utilizing a standardized self-built production base for end-to-end precision manufacturing eliminates intermediaries and ensures consistent injection height across cylinders. This reduces maintenance costs and provides a robust and reliable power guarantee for long-term equipment operation.
100% fully simulated digital bench rigorous quality inspection.
Problems Solved: 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.
Value Brought: 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.
Problems Solved: 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.
Value Brought: 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.
Problem Solved: Addressing the issue of premature wear and valve core seizure caused by variations in diesel lubricity and sulfur content across different regions.
Benefits: 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.

Application Scenarios
Open-pit mining and continuous loading of large-tonnage rocks: In the dusty and harsh working environment of open-pit mines, heavy equipment is at full power, grabbing and loading heavy loads onto hard rock strata. As hydraulic resistance surges instantaneously, the 3093415 injector, with its microsecond-level electronic control response, establishes excellent atomization pressure, ensuring that the engine can still output continuous high torque even when facing drastic speed fluctuations. The complex actions are smooth and continuous, completely avoiding engine stalling and misfires.
High-load all-weather power supply and infrastructure emergency support: In remote infrastructure construction sites or large mining areas lacking stable power grids, large generator sets driven by large-displacement diesel engines serve as the core power source, operating continuously for dozens of hours without interruption. With the frequent switching on and off of large-scale special electrical equipment on construction sites, the electrical load changes rapidly. The fuel injector, relying on extremely high consistency and rapid injection control, ensures that the generator set speed remains stable at the standard range, and that the output voltage and frequency do not drift.
Frequently Asked Questions
Q: Can I use the product directly after installation? Is it necessary to enter a correction code?
A: Each fuel 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.
