fuel injector is a premium OEM-spec replacement component professionally engineered for c-aterpillar 3116 diesel engines, with full extended compatibility for c-at 3114 and 3126 engine series. Built with heavy-duty hardened internal components and precision CNC hydraulic grinding technology, it delivers stable and uniform fuel atomization, zero high-pressure fuel leakage, and long-lasting heavy-duty durability, making it ideal for construction, mining, marine, and industrial heavy equipment applic-ations. Each unit undergoes 100% full pre-delivery testing covering leakage, spray pattern, fuel pressure and flow rate, featuring a true plug-and-play design that requires no extra calibration or on-site modific-ation, perfectly matching the original c-aterpillar fuel system performance standards and operating parameters for reliable long-term use.

2. Core Performance & Technical Parameters
| Parameter | Value | Performance Advantage |
| Injection Opening Pressure | 30 ± 0.5 MPa | Precision matched to c-at 3116 engine load and daily operating habits, ensuring stable, thorough and efficient fuel combustion under full working conditions, eliminating power lag, fluctuation and weak acceleration issues |
| Needle Valve Design | Heavy-Duty Case-Hardened Needle Seat | Enhanced wear resistance, impact resistance and high-temperature fatigue durability, greatly extending service life under long-hour high-load operation, suitable for continuous heavy-duty work in harsh sites |
| Body Processing | Precision Hydraulic Grinding & Fine Finishing | Ensures ultra-precise fuel delivery and uniform cone atomization, effectively reducing fuel waste, black smoke and incomplete combustion, optimizing overall engine power output |
| Needle-to-Body Gap | Micron-Level Ultra-Precise Tolerance | Guarantees zero fuel leakage under high working pressure, stable hydraulic performance and consistent engine power output, completely fixing idle jitter and sudden power drop problems |
| Spray Pattern | Optimized Cone Atomization (OEM Standard) | Significantly improves fuel combustion efficiency, cuts overall fuel consumption by 15%-20%, lowers exhaust emissions and meets global environmental standards for construction and mining machinery |
| Service Life | ≥ 2,800,000 Injection Cycles | Strong resistance to oxidation, fuel corrosion and mechanical fatigue, performs stably in harsh environments like high dust, extreme temperature and continuous heavy load |
