Fuel Injector Valve 3095773 3071497 3087587 3076703 3076132 3076130 for Cum-mins K19 Kta19 Kta38 Engine

Product Description

This industrial-grade electronically controlled unitary diesel injector (OE No.: 3076703) is a high-precision fuel injection device specifically designed for large-displacement, heavy-duty engine systems. It is precisely adapted to 15L series high-horsepower diesel engines and is widely used in heavy-duty long-haul trucks, highway transport tractors, special off-highway dump machinery, and high-power mobile industrial generator sets. This product adopts a reinforced electronically controlled unitary injection (EUI) system architecture, focusing on providing high resistance to fluid shock and precise fuel cut-off atomization geometry. Once your heavy-duty machinery is equipped with this new injector and put into operation, the operator will intuitively feel the crisp response of the engine during cold starts. Issues such as unstable speed, horsepower drops, and stalling vibrations caused by aging and depressurization of fuel supply components will completely disappear. Throttle feedback is extremely smooth and linear, ensuring the continuous and powerful output torque for high-value machinery to operate at full speed.

Product Advantages

• Large-scale, self-owned factory, direct sales. Vertically integrated manufacturing bases directly eliminate the multi-level price markups of traditional cross-border parts trading, completely eradicating the predicament of high premiums and shoddy products frequently encountered in overseas distribution markets for heavy-duty special parts. From the precision grinding of internal needle valve components to the overall 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 reorganization and maintenance costs of fleets.
• Normalized saturated warehousing with readily available stock for lightning-fast delivery. For this key consumable injector (3076703), which has an extremely large market share in heavy-duty freight and special industrial power sectors, our modern warehouses maintain a consistently saturated inventory of finished products. This effectively mitigates the huge downtime losses caused by critical fuel system component failures that disrupt engineering projects or highway freight fleets, forcing machinery to remain idle for extended periods, supporting 24/7 lightning-fast cross-border delivery.
• Digital closed-loop 100% fully automated rigorous pressure inspection. Each electronic fuel injector undergoes rigorous screening on a dedicated fully automated testing bench before being sealed and packaged. Comprehensive closed-loop calibration is performed on its maximum opening rail pressure, multi-point dynamic injection volume, return rate, and transient electronic control response of the control valve coil. 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, common in low-end substitutes. This provides frontline mechanics with a worry-free experience of successful installation on the first try, requiring no rework or fine-tuning.

Application Scenarios

• Heavy-Duty Highway Logistics and Mountainous Steep Slope Freight: In cross-border logistics and on long, steep mountain roads with significant undulations, heavy-duty tractor-trailers carrying tens of tons of cargo face extremely demanding horsepower tests. When drivers frequently change lanes and press the accelerator hard, the 3076703 injector, with its excellent electronic control response, ensures 100% complete combustion of fuel in the cylinder, providing the engine with high torque at low speeds, guaranteeing efficient and timely delivery of long-haul freight.
• High-Intensity Ore Transportation in Large Open-Pit Mines: In dusty, harsh mining environments, large-tonnage construction machinery needs to perform high-load excavation continuously every day. The injector's internal components undergo enhanced surface corrosion protection and nano-hardening treatment, enabling it to withstand the high fluid impacts of rough working environments, providing stable and continuous fuel supply, and effectively avoiding the huge collateral damage to the entire operation line caused by sudden breakdowns in remote areas.
• Commercial Vehicle Specialized Chain Repair Center Overhaul and Refurbishment: When heavy-duty trucks or generator sets are brought in for major repairs due to prolonged use of impure diesel fuel, resulting in severely worn injector valve cores, frequent heavy black smoke emissions, and extreme difficulty starting in cold conditions, experienced mechanics directly select this brand-new injector, perfectly matching the original factory parameters. Because the physical interface and electronic control plug fit seamlessly, ignition is successful on the first try, and all pressure and return fuel data perfectly meet standards.
