<Product Description>
This high-pressure electronically controlled nozzle unit (standard part number: 3071497, common cross-reference numbers include 3071497PX, 3087557, 3411767, etc.) is precision-engineered for heavy-duty transport trucks, large-tonnage engineering equipment, and large-displacement diesel power platforms (such as N14 and NT855 series engines). As a micro-precision actuator in the high-pressure fuel supply system, it plays a crucial role in rapidly metering and atomizing diesel fuel into ultra-fine particles within milliseconds, ensuring complete fuel-air mixing and efficient combustion, releasing abundant and stable power output.
The product adheres to the manufacturing standard of "micron-level high-pressure injection and millisecond-level rapid response." The core valve needle assembly and solenoid valve core are made of selected aerospace-grade special alloy steel, undergoing micron-level precision grinding and low-friction polishing. The surface is coated with a high-density anti-coking hardening coating, easily resisting early erosion caused by impurities in inferior diesel fuel. After the equipment is replaced, operators and drivers will experience noticeable improvements in operation: engine ignition and start-up are crisp and clean, and the severe vibrations and jerks at low idling speeds have subsided; under full-load climbing or high-intensity continuous operation, throttle control is smooth and precise, power is continuous, abundant, and stable, and black smoke emissions from the exhaust are significantly reduced, resulting in excellent overall fuel economy.

<Product Advantages>
Problems Solved: Traditional OEM and multi-level procurement models involve complex processes that easily lead to excessive tolerances in parts, uneven fuel supply to cylinders, and high-pressure leaks, while significantly increasing procurement costs.
Value Brought: Relying on a self-built standardized production plant for precision manufacturing throughout the entire process eliminates layers of intermediaries, ensuring consistent injection height across cylinders. This significantly reduces maintenance costs while providing a solid and reliable power guarantee for long-term equipment operation.
Problems Solved: Addressing common issues with low-end fuel injectors, such as injection atomization deviation, incomplete combustion due to sluggish solenoid valve response, engine misfires, idling vibrations, and wasted time and extra costs associated with secondary disassembly and reassembly.
Value Brought: Each injector undergoes fully automated digital testing before leaving the factory. Under 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 reassembly.
Problems Solved: Commercial vehicles and construction machinery are high-upload, high-revenue tools. Downtime due to fuel system malfunctions can result in costly delays, compensation claims, and lost work time.
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 logistics and delivery cycles. This helps fleets and owners quickly restore equipment availability and effectively avoids downtime losses.
Problems Solved: Addresses issues such as premature wear of valve components, needle valve jamming, and excessive return oil caused by variations in diesel lubricity and particulate impurities in different regions.
Value Brought: The core valve assembly components utilize high-strength special bearing steel and undergo 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>
Intercity Heavy-Duty Freight Transport and Long-Distance Highway Cruise: Large semi-trailer tractors fully loaded with cargo travel for extended periods on inter-provincial trunk lines, requiring the engine to continuously output high torque. When drivers experience weak acceleration, decreased power when climbing hills, or abnormally increased fuel consumption, they should promptly replace the aging original parts and install this high-precision fuel injector. After replacement, high-pressure diesel atomization is uniform and sufficient, the accelerator pedal response is compact and smooth, effectively reducing overall operating costs and ensuring efficient and stable long-distance transportation.
Open-Pit Mining Loaders and Construction Machinery Continuous High-Load Operations: Large engineering dump trucks and excavators operate continuously in high-dust, harsh terrain environments, placing extremely high demands on the stability of the fuel supply system. When the equipment exhibits severe idling vibration, difficulty starting, or excessive emissions, on-site maintenance personnel promptly replace the entire injector system. Precise injection control ensures stable output even under extreme operating conditions, preventing engine stalling or work delays caused by uneven fuel supply.
Application Scenarios
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, maintaining a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can be quickly scheduled for production.
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.
