Product Condition	Brand New OEM Standard / Remanufactured to c-at Original Factory Spec; 100% Pre-Delivery Tested (leakage, spray, pressure, flow rate)
Control Type	Mechanical Direct Injection / Solenoid-Assisted Hydraulic; fully optimized for c-at 3116 engine fuel system
Fuel Compatibility	Standard diesel, low-sulfur diesel, high-sulfur diesel, marine diesel; anti-coking, anti-impurity and anti-corrosion internal design
Net Weight	0.7kg – 0.75kg; lightweight structure for quick installation, disassembly and daily maintenance
Installation Feature	Plug-and-Play Direct Replacement; identical mounting holes, interface size and connection specs as original c-at injector, no modific-ation or calibration required

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 operating characteristics, ensuring stable, thorough and efficient fuel combustion under all working conditions
Needle Valve Design	Heavy-Duty Case-Hardened Needle Seat	Maximizes wear resistance, impact resistance and fatigue durability, greatly extending service life under long-hour high-load operation
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
Needle-to-Body Gap	Micron-Level Ultra-Precise Tolerance	Guarantees zero fuel leakage under high pressure, stable hydraulic performance and consistent engine power output, eliminating power fluctuations
Spray Pattern	Optimized Cone Atomization (OEM Standard)	Significantly improves combustion efficiency, reduces fuel consumption by 15%-20%, lowers exhaust emissions and meets global environmental operation standards
Service Life	≥ 2,800,000 Injection Cycles	Strong resistance to oxidation, corrosion and fatigue, suitable for harsh working environments like high dust, extreme temperature and heavy load

3. Material & Structural Advantages

Component	Material & Craft	Benefit for Users
Injector Body	High-strength forged alloy steel, precision CNC machining, multi-stage heat treatment	Withstands ultra-high fuel pressure and extreme temperature changes, anti-deformation, anti-cracking, ensures long-term stable performance in harsh sites
Needle Valve Assembly	Case-hardened high-carbon alloy steel, precision grinding, anti-wear composite coating	Minimizes long-term wear, maintains consistent injection accuracy, reduces maintenance frequency and replacement costs for equipment owners
Sealing Parts	High-temperature & oil-resistant fluororubber, precision mold pressing	Effectively prevents fuel leakage and air intake, ensures stable engine idle and smooth acceleration, avoids abnormal noise and cylinder misfire

4. Applicable Equipment Models

Equipment Type	c-at Models Powered by 3116 Engine
Excavators	320B, 322B, 325B, 330B series
Wheel Loaders	928G, 938G, 950G, 950F series
