3126b 170-9074 1709074 Common Rail Fuel Injector for Cater-pillar Diesel Engine

This precision diesel injector (OE: 170-9074) is a high-efficiency fuel supply core specifically developed for Cater-pillar 3406 series and C-series heavy-duty engines. It employs advanced Hydraulic Drive Electronic Control (HEUI) injection technology, enabling millisecond-level precise control of fuel injection pressure to ensure highly efficient fuel mixing and combustion within the cylinder. After installation, users will experience extremely rapid engine cold start response, smooth idling, and powerful, linear power output under heavy loads. This component effectively improves power loss and exhaust smoke caused by fuel metering errors. Constructed with wear-resistant alloys and high-performance sealing materials, it provides strong, durable, and economical power support for your construction machinery.

Standardized Flexible Manufacturing Enhances Performance Consistency: Leveraging our fully equipped modern factory, each 170-9074 injector is meticulously crafted using nanometer-level CNC equipment. This rigorous process effectively avoids part size deviations, ensures highly uniform nozzle geometry, achieves balanced fuel distribution across cylinders, and significantly improves the overall engine's stability and responsiveness.

A well-established, large-scale readily available inventory system: Understanding the stringent downtime requirements of heavy equipment, we have established a comprehensive finished goods inventory system. Whether you urgently need a single unit or are undertaking a large-scale upgrade for your fleet, we can process your requests immediately and deliver them with lightning speed, greatly reducing the downtime after equipment replacement parts and ensuring your production projects consistently move forward smoothly.

Comprehensive, multi-dimensional pressure performance quality inspection: All finished products must undergo multiple rounds of testing on a professional high-pressure test bench, covering core indicators such as flow consistency, opening pressure, and dynamic sealing. This stringent quality barrier successfully avoids the risk of early installation failure, allowing you to achieve original factory-level power performance upon initial installation and reducing the hassle of repeated disassembly and reassembly.

High-performance wear-resistant materials enhance service life: To address the long-term challenges of diesel engines operating under high temperature, high pressure, and complex impurities, we have implemented special reinforcement treatments on core moving parts. This process significantly enhances the needle valve's resistance to hard impurities and high-temperature oxidation, maintaining accurate oil supply even under continuous high-load extreme operating conditions. This extends your equipment's maintenance cycle and saves on long-term maintenance budgets.

Open-Pit Large-Scale Ore Mining Operations: In mining environments, excavators and dump trucks need to maintain continuous full-load operation for extended periods, placing extremely high demands on engine fuel supply stability. After equipping this injector, the engine delivers stable and precise fuel supply under high load conditions, effectively preventing power loss and ensuring the continuous operation of machinery under harsh conditions, significantly improving the output per unit time in ore mining.

Large-scale earthwork construction for urban infrastructure: During pit excavation or leveling operations, machinery frequently experiences acceleration, deceleration, and gravity load switching. This injector, with its excellent instantaneous response, allows the engine to quickly obtain ample fuel support during sudden load changes, completely eliminating power lag. This not only makes machinery operation smoother but also reduces on-site exhaust emissions through precise combustion logic, better meeting urban environmental protection standards.

• Q: Is it necessary to use a diagnostic tool for matching after installation?
  A: This model will work normally after proper installation and thorough bleed air extraction. If your engine management system has extremely high precision, it is recommended to use a diagnostic tool for a simple fuel injection data matching after installation for better results.
• Q: Are the injectors you provide original parts or high-performance replacement parts?
  A: This product is a high-performance replacement part manufactured strictly according to the original manufacturer's technical specifications and precision processes. It matches the original manufacturer in output accuracy and material durability, and offers excellent value for money.
• Q: How long is the product warranty period?
  A: We offer a 12-month after-sales warranty on all products sold. During this period, if performance problems are not caused by improper operation, we promise to provide a free replacement with a new product.
• Q: What key precautions should be taken during installation?
  A: The cleanliness of the installation environment is crucial. Ensure that no foreign objects enter the fuel line, and when replacing the injector, we recommend replacing the fuel filter with a high-quality one to maintain the long-term operating accuracy of the nozzle.
