Common Rail Fuel Injector 249-0705 10r-7236 for Cater-pillar Excavator 2490705 10r7236 C13 Engine Injector

This 249-0705 high-precision electronically controlled single-unit diesel injector (EUI) is a high-efficiency fuel supply device designed specifically for heavy-duty industrial power systems. It is precisely adapted to large-displacement heavy-duty diesel engines such as the C15, C16, and 3406E, and is widely used in special-purpose highway trucks, large-tonnage tracked excavators, mining dump trucks, and continuously operating industrial-grade large generator sets. The product design focuses on precise metering and multi-injection control under high-pressure mechanical drive, relying on micron-level multi-pore atomization technology to comprehensively optimize in-cylinder combustion efficiency. When your equipment is equipped with this new injector and put into operation, you will immediately feel the crisp response of the engine during cold starts. Previously sluggish power drops, overload stalling, and idling vibrations will disappear, exhaust emissions will be significantly improved, and the powerful torque output will bring you an extremely smooth and stable heavy-duty handling experience.

• Large-scale, self-owned factory supply. We directly eliminate the layers of intermediaries and price premiums in the traditional cross-border procurement chain, completely resolving the predicament of overseas buyers frequently encountering high premiums and /refurbished parts in the retail market due to the high precision of our products. From the precision grinding of internal valve cores to the assembly of the overall electronic control assembly, we achieve closed-loop control of the production line, providing global buyers with transparent and reasonable direct-from-the-factory prices, significantly reducing the long-term maintenance costs of fleets.
• Routine saturated warehousing and rapid distribution of in-stock goods. For this key powertrain component, which has a large presence in mining and infrastructure construction, our modern warehouses maintain a saturated stock of 249-0705 fuel injectors year-round. This effectively mitigates high-risk operational crises such as forced downtime due to sudden wear of core fuel components or system depressurization, supporting 24/7 cross-border lightning-fast dispatch and ensuring efficient project progress.
• Digital closed-loop 100% fully automated rigorous quality inspection. Each individual injector undergoes rigorous testing on a dedicated fully automated testing bench for EUI (Electronic Injector Units) before being sealed and delivered. This involves comprehensive closed-loop calibration of high-pressure opening pressure, multi-point dynamic injection volume, and return rate. This effectively eliminates the fatal hidden dangers of needle valve adhesion and high-pressure dripping in the cylinder leading to carbon buildup and cylinder scoring, commonly found in low-end, inferior products. This provides frontline technicians with the peace of mind of successful installation on the first attempt, eliminating the need for any rework or recalibration.

• Large Open-Pit Mine Crushing and All-Weather Heavy-Duty Transportation: In harsh environments with flying sand and rocks, special trucks equipped with large-displacement heavy-duty engines need to carry tens of tons of ore up steep slopes continuously. Faced with such extreme loads, the 249-0705 injector, under the precise scheduling of the electronic control unit, provides extremely stable and sustained mechanical single-unit pressurized injection, ensuring complete fuel combustion, giving the engine a powerful torque that doesn't drop in speed, and guaranteeing efficient all-weather operation of transportation in the mining area.
• Independent Long-Term Power Supply for Field Oil Fields and Infrastructure Construction Sites: In desert drilling sites far from urban power grids or large bridge construction sites, high-power diesel generator sets provide power for all heavy-duty needs. When faced with high-power mechanical starts or sudden increases in electrical load, the injector, with its excellent wear resistance and high resistance to fluid shock, stably regulates the fuel supply for each cycle, ensuring that the generator speed does not fluctuate drastically and that the output frequency remains a constant current with extremely safe operating frequency.
• Engineering 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 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.
