Company Information
Product Description
This high-pressure electro-hydraulic unit fuel injection device (standard part code: 236-0957 / 2360957, common OE cross-reference and interchangeable identification numbers include 10R-8501, 10R8501, 10R-1262, 10R1262, 236-0962, etc.) is meticulously crafted for heavy engineering construction machinery, large-tonnage work equipment, and industrial diesel power platforms (such as the C9 series 8.8L inline six-cylinder diesel engine, commonly installed in 330C and 330D crawler excavators, 966G II and 972G II wheel loaders, and 140M graders, etc.). As the core control and spray execution element of the electro-hydraulic unit injection (HEUI) system, it is responsible for accurately metering high-pressure diesel fuel and rapidly converting it into micron-level ultrafine atomized particles with a microsecond-level response, promoting comprehensive and uniform mixing of fuel and intake airflow for efficient and complete combustion.
The product adheres to industrial standards of "ultra-high pressure atomization and millisecond-level rapid response." The core needle valve assembly and control valve core are made from carefully selected aerospace-grade hardened special alloy steel, combined with 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, maintenance personnel and equipment operators will experience a clear and intuitive performance improvement: crisp and rapid starting, with the severe vibration at low-speed idling subsiding and becoming smooth; when facing heavy-duty tunneling, steep slope climbing, or high-load continuous operation, the control lever and throttle response are tight and smooth, acceleration is rapid and the explosive power is continuous, while significantly reducing black smoke from exhaust, resulting in a satisfactory fuel consumption control experience.
Product Advantages
Advantages: Integrated precision manufacturing in a physical intelligent factory.
Problems Solved: Addresses issues arising from traditional OEM and multi-level distribution chains, such as accumulated tolerance issues in parts matching, uneven fuel supply to cylinders, and potential high-pressure leaks, while effectively reducing intermediate procurement costs.
Value Gained: Leveraging a self-operated standardized production base for precise end-to-end control, eliminating intermediate markups, and ensuring highly consistent fuel injection volumes across cylinders. This reduces maintenance budgets while providing robust and reliable power for vehicle operation.
Advantages: Rigorous quality inspection using a full-condition ultra-high-pressure digital test bench.
Problems Solved: Addresses issues such as response delays, pressure relief jamming leading to engine misfires and vibrations, and wasted time and money due to repeated disassembly and adjustment caused by inferior parts.
Value Gained: Each injector undergoes automated testing on a test bench before leaving the factory. Flow rate and sealing performance are calibrated 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 delivery.
Problem Solved: Addressing the costly delays and lost work due to fuel system malfunctions causing breakdowns and shutdowns for high-upload productivity tools like construction machinery and commercial vehicles.
Value Brought: Our warehousing center maintains ample stock of best-selling specifications year-round. Orders are responded to quickly, with priority packing and dispatch 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.
Problem Solved: Addressing the issue of premature wear and valve core seizure caused by variations in diesel lubricity and sulfur content in different regions.
Value Brought: Core valve components utilize high-strength special bearing steel and a surface corrosion-resistant 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.

Application Scenarios
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.
Frequently Asked Questions
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.
