fuel injector is a high-performance 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 upgraded heavy-duty hardened internal components and precision CNC hydraulic grinding technology, it delivers ultra-stable fuel atomization, zero high-pressure fuel leakage, and enhanced heavy-duty durability, making it the ideal choice for construction, mining, marine, agricultural and industrial heavy equipment operating in harsh conditions. Each unit undergoes 100% full pre-delivery testing covering leakage, spray pattern, fuel pressure and flow rate calibration, 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 long-term reliable use.

2. Core Performance & Technical Parameters
| Parameter | Value | Performance Advantage |
| Injection Opening Pressure | 30 ± 0.3 MPa | Higher precision pressure tolerance than standard models, perfectly matched to c-at 3116 engine load and continuous heavy-duty operation, ensuring stable, thorough and efficient fuel combustion under full working conditions, eliminating power lag, fluctuation and weak acceleration issues completely |
| Needle Valve Design | Upgraded 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 construction and mining sites |
| Body Processing | Precision Hydraulic Grinding & Mirror Finishing | Ultra-smooth internal surface ensures ultra-precise fuel delivery and uniform cone atomization, effectively reducing fuel waste, black smoke and incomplete combustion, optimizing overall engine power output and response speed |
| 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 Fine Cone Atomization (OEM Standard) | Significantly improves fuel combustion efficiency, cuts overall fuel consumption by 18%-22%, lowers exhaust emissions and meets global environmental standards for construction and mining machinery |
| Service Life | ≥ 3,000,000 Injection Cycles | Strong resistance to oxidation, fuel corrosion and mechanical fatigue, performs stably in harsh environments like high dust, extreme temperature, humidity and continuous heavy load |
