This high-pressure electro-hydraulic unit injection valve (standard part code: 0R-1759 / 0R1759, common interchangeable parts and OE identification numbers include 102-2014, 1022014, 0R-8772, 0R8772, 102-2015, etc.) is meticulously designed for medium and heavy-duty construction machinery, industrial-grade work equipment, and high-power diesel power platforms (such as the 3116 series 6.6L diesel engine, matched with 320, 322, and 325 series tracked excavators, 950F and 960F wheel loaders, and 120G and 140G graders). As a key control actuator of the HEUI electro-hydraulic unit injection system, it is responsible for accurately metering high-pressure diesel fuel and rapidly dispersing it into ultra-fine atomized particles within microseconds, promoting comprehensive and uniform mixing of fuel and intake airflow for efficient and complete combustion.
The product adheres to the manufacturing standards of "high-pressure particle refinement and microsecond-level ultra-fast response." The internal needle valve assembly and armature control valve core are made from carefully selected 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 replacement and installation, mechanics and equipment operators will experience a clear and intuitive performance improvement: crisp and clean starts, and the severe vibrations and jerks at low idle speeds are stabilized; when facing heavy-duty excavation, high-load bulldozing, or steep slope climbing conditions, the control lever and throttle control are tightly integrated, resulting in rapid acceleration and continuous bursts of power, while significantly reducing black smoke from exhaust fumes, bringing an excellent overall fuel economy control experience.
Advantages: Precision manufacturing throughout the entire process at our self-operated modern production base.
Problems Solved: Addressing the issues of accumulated tolerances exceeding standards in parts fitting, uneven fuel supply to cylinders, and high-pressure leakage risks caused by traditional OEM and multi-level distribution models, while also significantly increasing procurement costs.
Value Brought: Precision manufacturing in a self-built, standardized production plant eliminates intermediaries and their markups, ensuring consistent injection height across all cylinders. This reduces maintenance costs and provides a robust and reliable power guarantee for long-term equipment operation.
Advantages: 100% fully simulated digital dynamic test bench for rigorous quality inspection.
Problems Solved: Addresses common issues in low-end components such as injection atomization deviation, incomplete combustion due to sluggish solenoid valve response, engine misfires, idling vibrations, and wasted time and additional costs associated with secondary disassembly and adjustment.
Value Brought: Each nozzle unit undergoes fully automated digital testing before leaving the factory. Under fully simulated high-temperature and ultra-high-pressure conditions, the injection volume and return oil sealing are precisely calibrated across different pressure ranges, ensuring immediate usability upon installation and significantly reducing time and costs associated with equipment disassembly and adjustment.
Advantages: Standardized large-scale warehousing for rapid allocation and shipping.
Problem Solved: Commercial vehicles and construction machinery are high-upload, high-revenue tools. If they become stranded due to fuel system failure, the resulting downtime and lack of materials can lead to costly delays, compensation claims, and lost wages.
Value Brought: Our warehousing center maintains a large inventory of best-selling specifications year-round. Orders are responded to quickly, with priority packing and shipping 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: Special bearing steel and nano-level anti-corrosion hardening coating.
Problems Solved: Addressing issues such as premature wear of components, needle valve jamming, and excessive oil return caused by variations in diesel lubrication and particulate impurities in different regions.
Value Brought: Core valve components utilize high-strength special bearing steel and a surface anti-corrosion hardening treatment, significantly improving fatigue resistance and wear resistance. This ensures stable performance even under harsh environments and prolonged high-load operation, avoiding the additional costs associated with frequent disassembly and repairs.

Open-pit Mining and Large Tracked Excavator Operations: Large excavators and mining loading equipment continuously excavate and load large rocks in harsh, high-dust, and high-intensity environments, placing extremely high demands on engine fuel supply stability and power output. When on-site operators notice a decrease in equipment digging force, significant and severe vibration at idle, or frequent black smoke from the exhaust pipe, maintenance personnel promptly replace worn parts and install this high-precision fuel injector. After replacement, fuel injection atomization is extremely uniform, and the hydraulic system power output is restored to ample and stable levels, ensuring efficient and uninterrupted mining operations.
Large-scale road construction and continuous operation scenarios for graders and bulldozers: When graders and bulldozers are engaged in highway infrastructure work, 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 engineering mechanic team will replace the entire fuel supply system. Precise electronic injection control restores smooth engine operation, significantly improving fuel efficiency and acceleration response, avoiding additional labor costs caused by construction downtime.
Q: Can I use the product directly after installation? Is it necessary 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 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.
