Product Description
This high-pressure electronic fuel injection assembly (standard product code: 1933613, common interchangeable numbers include 1933613C91, 1933613C92, 1842231C91, etc.) is meticulously crafted for medium and heavy-duty commercial trucks, city buses, and special diesel-powered equipment (such as VT365 and DT466 series diesel engines). As a micro-precision control and execution unit in the high-pressure fuel system, it undertakes the crucial task of rapidly metering and atomizing diesel fuel into ultra-fine particles within milliseconds, and is widely used in intercity trunk freight, public transportation passenger transport, and high-intensity special operations.
The product adheres to the design specifications of "high-pressure particle refinement and high-frequency rapid control." The core valve needle assembly and solenoid valve core undergo extremely high-precision geometric grinding and low-friction polishing, and the surface is covered with a high-density anti-coking hardened coating, which effectively prevents early erosion caused by diesel impurities. After the replacement and installation, drivers and equipment operators will experience immediate improvements in operation: engine starts are crisp and clean, and vibrations and minor shaking at low idle speeds are completely eliminated; under full-load climbing or high-load cruising conditions, throttle control is tight and smooth, power is continuous and abundant, and black smoke from the exhaust is significantly reduced, resulting in excellent overall fuel economy.
Product Advantages
Advantages: Integrated intelligent manufacturing in a self-operated automated factory.
Problems Solved: Addresses the issues of dimensional discrepancies in component fit, uneven fuel supply to cylinders, and high-pressure leakage risks that are easily caused by the complex processes of traditional OEM procurement, while avoiding the increased procurement costs from intermediaries.
Value Brought: Relying on a self-built standardized production base for precision manufacturing throughout the entire process, eliminating layers of intermediaries and ensuring consistent injection height in each cylinder, significantly reducing maintenance costs while providing a solid and reliable power guarantee for long-term equipment operation.
Advantages: Full-condition ultra-high pressure dynamic micron-level bench inspection.
Problems Solved: Addresses common issues in low-end fuel injectors such as poor atomization, incomplete combustion due to sluggish solenoid valve response, engine misfires and vibrations, and wasted time and additional costs associated with secondary disassembly and adjustment.
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 adjustment.
Advantages: Large-scale warehousing and readily available stock for rapid delivery response.
Problems Solved: Addresses the significant downtime and contract default risks resulting from fuel system failures and breakdowns of commercial vehicles and engineering equipment due to lack of materials.
Value Brought: The warehousing center maintains a sufficient stock of best-selling specifications year-round. After order confirmation, a rapid response and priority packing and dispatch within 24-48 hours greatly shortens the logistics and delivery cycle, helping fleets and owners quickly restore equipment operational readiness and effectively avoiding downtime losses.
Advantages: Nanoscale DLC coating and special wear-resistant alloy valve assembly.
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 Passenger Transport and School Bus High-Frequency Cruise Operations: Passenger buses and school buses undertake high-density transportation tasks daily, placing extremely high demands on engine stability and emissions. When drivers notice insufficient starting power, significant idling vibration, or increased fuel consumption, promptly replace the aged nozzles with this electronically controlled fuel injector. After replacement, diesel atomization is uniform and sufficient, throttle feedback is smooth, effectively improving driving comfort and reducing overall operating costs.
Urban Special Operations and Logistics Freight Conditions: Special operation vehicles and medium-sized trucks often face complex road conditions such as frequent starts and stops, long periods of idling, and fully loaded driving. When a vehicle experiences starting difficulties, black smoke during acceleration, or power loss, the mechanic replaces the entire injector system. Precisely controlled injection flow allows the engine to quickly restore full torque output, preventing downtime due to fuel supply imbalances.
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 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.
