200-1117 New Diesel Fuel Injector 2001117 for Cater-pillar C15 Diesel Engine

<Product Description>

This high-pressure electro-hydraulic unit injection mechanism (standard part code: 200-1117, common OE cross-reference and interchangeable identification codes include 2001117, 0R-9350, 0R9350, 177-4753, 0R-8782, etc.) is meticulously developed for medium and heavy-duty construction machinery, mining equipment, and industrial-grade diesel power platforms (such as the 3126/3126B series 7.2L diesel engine, matched with 322C and 325C tracked excavators, 950G and 962G wheel loaders, and 120H and 135H graders, etc.). As the core actuator of the HEUI electro-hydraulic unit injection system, it is responsible for accurately metering and atomizing high-pressure diesel fuel into nano-scale ultra-fine atomized particles within milliseconds, promoting comprehensive and uniform mixing of fuel and intake airflow, achieving full and efficient combustion and abundant and powerful power release.

Adhering to the manufacturing standards of "high-pressure ultra-fine particle atomization and millisecond-level ultra-fast response," the product uses carefully selected aerospace-grade quenched special alloy steel for its internal needle valve assembly and valve core components. Combined with ultra-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 replacement and installation, operators will experience a significantly improved performance: engine ignition and start-up are crisp and rapid, and the severe vibrations at low-speed idling have subsided and become smooth. When facing heavy-duty excavation, high-load bulldozing, or steep slope climbing conditions, the pedals and levers respond smoothly and precisely, providing rapid acceleration and continuous bursts of power, while significantly reducing black smoke emissions and delivering an excellent overall fuel control experience.

<Application Scenarios>

Open-pit Mining and Large Tracked Excavator Operations: Large excavators and mining loading equipment continuously excavate and load large rocks in harsh, high-dust, and high-intensity environments, placing extremely high demands on engine fuel supply stability and power output. When on-site operators notice a decrease in equipment digging force, significant and severe vibration at idle, or frequent black smoke from the exhaust pipe, maintenance personnel promptly replace worn parts and install this high-precision fuel injector. After replacement, fuel injection atomization is extremely uniform, and the hydraulic system power output is restored to ample and stable levels, ensuring efficient and uninterrupted mining operations.

Large-scale road construction and continuous operation scenarios for graders and bulldozers: When graders and bulldozers are engaged in highway infrastructure work, 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 engineering mechanic team will replace the entire fuel supply system. Precise electronic injection control restores smooth engine operation, significantly improving fuel efficiency and acceleration response, avoiding additional labor costs caused by construction downtime.
