Product Description

This 171-9710 high-precision electronically controlled single-unit diesel injector is custom-designed for industrial heavy-duty engine systems, serving as a core assembly for precise fuel supply and efficient combustion. It is perfectly compatible with large-displacement heavy-duty diesel engines such as the 3196 and C12, and is widely used in tracked heavy excavators, large on-road/off-road dump trucks, bulldozers, and high-power marine generator sets. The product integrates cutting-edge hydrodynamic micro-atomization technology with a high-sensitivity solenoid valve control system, aiming to maintain a perfect injection curve under extreme loads. When your heavy equipment is equipped with this new injector and started, you will immediately feel the engine's throttle response become more agile and precise. Problems such as severe vibrations, cold start difficulties, and black smoke from the exhaust, previously caused by aging and depressurization of fuel supply components, disappear. The engine operates with a solid, crisp sound and extremely abundant output torque, allowing heavy-duty vehicles to return to peak operating performance.

Product Advantages

• Large-scale, self-owned factory direct sales manufacturing We directly eliminate the layers of markups from multiple intermediaries in the traditional multinational procurement chain, completely resolving the predicament of stockouts, high premiums, and inconsistent quality for old or specialized heavy machinery parts in the market. From precision-forged housings and valve cores to wiring harnesses and sockets, we achieve closed-loop control throughout the entire factory chain, providing global buyers with highly attractive first-hand factory prices and significantly reducing the long-term restructuring and maintenance costs of fleets.
• Standardized, large-capacity, saturated spot warehousing. For this evergreen powertrain with a large global presence in infrastructure, mining, and maritime transport, our modern logistics centers maintain a saturated stock of 171-9710 injectors year-round. This fundamentally mitigates the high risk of delays and defaults caused by the lack of critical components, forcing engineering teams or ship owners to indefinitely halt operations. It supports lightning-fast delivery, allowing high-value machinery to quickly resume operations and generate profits.
• Digital closed-loop, 100% fully automated, and rigorous quality inspection. Each electronic fuel injector undergoes rigorous calibration on a high-precision CNC testing bench before being sealed and delivered. This involves comprehensive closed-loop calibration of the injection rail pressure, multi-point dynamic injection volume, return rate, and solenoid valve transient response. This effectively eliminates the fatal hidden dangers common in low-end, inferior products on the market, such as needle valve adhesion, high-pressure dripping leading to cylinder carbon buildup, and even cylinder scoring. This provides installation technicians with a worry-free experience, ensuring successful installation on the first try and eliminating the need for repeated rework.

Application Scenarios

• Large-scale open-pit mine rock stripping and all-weather heavy-duty transportation: In harsh environments with flying sand and rocks, heavy-duty special trucks equipped with C12 engines need to carry tens of tons of ore up steep slopes continuously. Faced with such extreme loads, the 171-9710 injector, under the precise scheduling of the electronic control unit, achieves microsecond-level fuel supply control, ensuring complete combustion of diesel fuel and providing the engine with robust torque without speed drop, guaranteeing efficient all-weather operation of transportation in the mining area.
• Continuous power supply from generator sets on deep-sea and near-shore vessels: In the engine rooms of ships far from land, in environments with high humidity and severe salt spray corrosion, high-power diesel generator sets provide power to all shipboard equipment and living systems. When encountering high-power marine machinery startup or a sudden surge in grid load, the injector, with its excellent wear resistance and high resistance to fluid shock, stably adjusts the fuel supply for each cycle, ensuring the generator does not fluctuate violently and outputs a constant-frequency, safe current.
• Heavy-Duty Construction Machinery Specialized Chain Repair Center Overhaul and Preparation: When customers' large construction machinery is brought in for major repairs due to long-term use of inferior diesel fuel containing moisture, resulting in damaged individual injector components, difficulty starting when hot, heavy black smoke, and frequent flashing fault codes on the dashboard, experienced mechanics directly select this brand-new injector that fully conforms to original factory specifications. Because the physical interface and electronic control plug fit perfectly, ignition is successful on the first try, and all return fuel parameters perfectly meet the standards.
