This model of high-pressure electro-hydraulic unit fuel injection device (standard part number: 100-7559 / 1007559, common OE cross-reference and interchangeable identification numbers include 0R-8682, 0R8682, 10R-0967, 10R0967, 104-9453, etc.) is specially manufactured for heavy engineering construction machinery, large-tonnage operating facilities and industrial diesel power platforms (such as 3116 series 6.6L inline six-cylinder diesel engines, often equipped in 320B, 322B tracked excavators, 950F, 960F wheel loaders and 120G, 130G graders and other large equipment). As the core control and micro-spray execution unit of the HEUI (High-Pressure Integrated Injection) system, it bears the heavy responsibility of precisely metering high-pressure diesel fuel and rapidly converting it into micron-sized ultrafine atomized particles with millisecond-level response. This promotes comprehensive and uniform mixing of fuel and intake airflow, achieving full and efficient combustion.
The product adheres to the design specifications of "high-pressure particle refinement and microsecond-level ultra-fast response." The internal needle valve assembly and control valve core are made of aerospace-grade quenched special alloy steel, combined with ultra-high precision geometric grinding and low-friction polishing. The surface is covered with a dense, anti-coking hardened coating, effectively preventing early erosion caused by diesel impurities. After the parts are installed, mechanics and equipment operators will experience a significant performance improvement: crisp and rapid starting, with the severe vibration at low-speed idling subsiding and becoming smooth; under heavy-duty excavation, high-load bulldozing, or steep slope climbing conditions, the control lever and accelerator pedal respond smoothly and precisely, with rapid acceleration and continuous bursts of power, while significantly reducing black smoke from exhaust fumes, resulting in a satisfactory fuel consumption control experience.
Advantages: Integrated intelligent manufacturing and precision engineering in a physical factory.
Problems Solved: Addresses issues arising from traditional OEM and multi-level distribution chains, such as accumulated tolerance issues in parts, uneven fuel supply to cylinders, and high-pressure leakage risks, while effectively reducing intermediate procurement costs.
Value Brought: Utilizing a self-operated standardized production base for precise end-to-end control, eliminating intermediate markups, and ensuring highly consistent fuel injection volume across cylinders, reducing maintenance budgets while providing robust and reliable power for equipment operation.
Advantages: Rigorous quality inspection using a full-condition ultra-high-pressure digital test bench.
Problems Solved: Addresses issues such as response delays caused by inferior parts, pressure relief jamming leading to engine misfires and vibrations, and the waste of time and money due to repeated disassembly and adjustment.
Value Brought: Each injector undergoes automated testing on a test bench before leaving the factory, calibrating flow rate and sealing performance under simulated high-temperature and ultra-high-pressure conditions, ensuring immediate usability upon installation and significantly saving time and costs associated with equipment disassembly and adjustment.
Advantages: Large-scale warehousing with readily available stock for rapid dispatch and shipment.
Problems Solved: Addressing the costly delays and lost work due to fuel system failures causing breakdowns in high-upload productivity tools like construction machinery and commercial vehicles.
Value Brought: The warehousing center maintains ample stock of best-selling specifications year-round. Orders are responded to quickly, with priority packing and shipment within 24-48 hours, significantly shortening logistics and delivery cycles. This helps fleets and owners quickly restore equipment availability and effectively avoids downtime losses.
Advantages: Aerospace-grade hardened alloy and corrosion-resistant coating.
Problems Solved: Addressing the issue of premature wear and valve core seizure caused by differences in diesel lubricity and sulfur content in different regions.
Value Brought: Core valve components utilize high-strength special bearing steel and surface anti-corrosion hardening treatment, significantly improving fatigue resistance and wear resistance. This ensures stable performance even in harsh environments and under prolonged high-load operation, avoiding the additional costs of frequent disassembly and repairs.

Open-Pit Mining and Large Tracked Excavator Operations: Large tracked excavators continuously excavate and load large rocks in harsh, high-dust, and high-load environments, requiring extremely high stability in fuel supply and explosive power. When operators notice a decrease in digging force, severe idling vibration, or black smoke from the exhaust pipe, maintenance personnel should promptly replace the fuel injector with this high-precision model. After replacement, fuel injection atomization is extremely uniform, and the hydraulic system's power output is restored to ample and stable levels, ensuring efficient progress in mining operations.
Large-scale highway infrastructure construction and continuous leveling operations: When graders and bulldozers are used in highway infrastructure construction, their engines need to maintain a stable low-speed, high-torque output for extended periods. When equipment experiences starting difficulties, sluggish acceleration, or abnormally high fuel consumption, the maintenance team will replace the entire fuel supply system. Precise electronic injection control restores smooth engine operation, significantly improving fuel efficiency and acceleration response, avoiding downtime costs.
Q: Can I use the product directly after installation? Is a correction code required?
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 scheduled for production line setup.
Q: How do you guarantee the quality and performance of your products before they leave 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 high-quality products from the outset.
Q: How long is the warranty period? What about after-sales service?
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 when using our products.
