This high-pressure electronically controlled nozzle unit (standard part number: 1731091, common OE cross-reference and interchangeable part numbers include 1731091PX, 1731091RX, 1703898, 1703898PX, etc.) is precision-manufactured for heavy-duty trucks, long-distance passenger buses, and large-displacement diesel power platforms (such as DC13, DC12, DT12 series heavy-duty diesel engines). As the micro-control actuator of the fuel supply and high-pressure injection system, it is responsible for rapidly metering diesel fuel within milliseconds and converting it into nano-sized ultrafine particles, promoting comprehensive and uniform mixing of fuel and intake air for complete and efficient combustion.
Adhering to the technical manufacturing standards of "high-pressure micro-atomization and millisecond-level ultra-fast response," the product uses carefully selected quenched special alloy steel for its internal needle valve assembly and armature control valve core. Combined with ultra-high precision geometric grinding and low-friction polishing processes, the surface is covered with a dense, anti-coking hardened coating, effectively preventing early erosion caused by diesel impurities. After replacement and installation, drivers and equipment operators will experience immediate performance improvements: rapid and smooth start-up, and complete elimination of severe vibrations at low-speed idling; under heavy-load climbing steep slopes or high-intensity long-term cruising conditions, the throttle pedal feedback is compact and smooth, providing continuous, abundant, and stable power, while significantly reducing black smoke emissions and delivering excellent overall fuel economy control.
Advantages: Direct shipping from our self-operated modern production base.
Problems Solved: Addressing the complex processes inherent in traditional OEM procurement models, which can easily lead to excessive tolerances in parts, uneven fuel supply to cylinders, and high-pressure leakage risks, while also 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 all cylinders. This reduces maintenance costs and provides a robust and reliable power guarantee for long-term equipment operation.
Advantages: 100% fully simulated digital bench rigorous quality inspection.
Problems Solved: Addresses quality issues common with low-quality parts, such as delayed solenoid valve response, internal pressure leakage, and needle valve jamming, leading to unstable power output 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 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 after installation and significantly saving time and costs associated with equipment disassembly and debugging.
Advantages: Regularly available large stock and rapid warehousing and distribution.
Problems Solved: Addresses the costly delays and lost work time caused by commercial vehicles and construction machinery being grounded due to fuel system failures and waiting for materials.
Value Brought: The warehousing center maintains ample stock of best-selling specifications year-round, enabling rapid response after order confirmation and priority packing and dispatch within 24-48 hours. This significantly shortens logistics and delivery cycles, helping fleets and owners quickly restore equipment availability and effectively avoiding downtime losses.
Advantages: Special hardened alloy wear-resistant and corrosion-resistant material.
Problems Solved: Addresses 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, greatly improving fatigue resistance and wear resistance. Even under harsh environments and prolonged high-load operation, it maintains stable performance, avoiding the additional costs of frequent disassembly and repair.

Heavy-Duty Long-Haul Logistics Transportation and Mountainous Steep Slope Climbing: Large semi-trailer tractors fully loaded with heavy cargo travel at high speeds for extended periods on inter-provincial highways, requiring the engine to continuously withstand high load pressure. When drivers notice the vehicle's inability to climb hills, abnormally high fuel consumption, or black smoke, they replace the original aging parts and install this high-precision fuel injector. After installation, the engine's fuel atomization effect is significantly improved, throttle response is more robust, effectively reducing overall fuel consumption and ensuring high efficiency and stability in long-distance transportation.
Intercity Long-Distance Passenger Transport and High-Frequency Cruise Scenarios for Highway Buses: Large highway passenger buses need to undertake high-intensity long-distance route tasks daily, making them extremely sensitive to the smoothness and reliability of engine operation. When fleet maintenance personnel notice starting delays, intermittent idling vibrations, or power loss in vehicles, they promptly replace the entire set of fuel injection actuators. After replacement, the engine runs quietly and stably, and the accelerator pedal feedback is delicate and precise, providing passengers with a smooth and comfortable ride.
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.
Q: How do you ensure product quality and performance 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.
