Core Product Advantages & Features
Our c-at 3116 105-1694 injector is built to outperform generic aftermarket parts, with premium design and manufacturing processes that replic-ate OEM performance. Below are the key features that make it the top choice for engine maintenance and repair:
| Feature c-ategory |
Detailed Advantage Description |
| Precision Fuel Delivery |
Adopts precision-machined needle valve assembly with clearance controlled at 1-3μm, ensuring consistent fuel injection volume and timing. Forms optimized S-shaped spray pattern for full combustion, reducing fuel waste by up to 8% and lowering black smoke emissions effectively. |
| Extreme Durability |
Made of high-strength alloy steel with hardened surface treatment, resistant to fuel corrosion, wear, and high-pressure impact. Built to withstand over 1,000,000 injection cycles under heavy load, extending service life and reducing frequent replacement costs. |
| Direct OEM Fit |
Manufactured according to original c-at 3116 engine dimensions and interface standards, plug-and-play installation, no modific-ation or adjustment needed. Perfectly matches engine fuel system, avoiding installation errors and compatibility issues. |
| Rigorous Quality Testing |
Each injector undergoes 5 full rounds of testing: spray pattern test, leakage test, pressure stability test, fuel delivery accuracy test, and durability simulation test. 100% qualified before shipment, ensuring stable performance right out of the box. |
| Wide Environmental Adaptability |
Suitable for low-sulfur diesel and various heavy-duty working conditions, resistant to high temperature, vibration, and dust. Works stably in construction sites, mines, marine environments, and other harsh scenarios. |
Common Faults Solved by This Injector
Replacing with our 105-1694 injector can quickly resolve typical fuel system failures of c-at 3116 engines, restoring engine power and efficiency:
Engine power loss, slow acceleration, and insufficient torque
Excessive fuel consumption, increased operating costs
Black smoke, white smoke, or abnormal exhaust emissions
Engine rough idle, stalling, and unstable operation
Fuel leakage, fuel dilution of engine oil, and premature component wear
Installation & Maintenance Tips
Always replace injectors in sets for 3116 engines to ensure balanced cylinder performance; avoid mixing old and new injectors.
Clean the fuel system and replace fuel filter before installation to prevent impurities from damaging the new injector.
Use professional torque tools for installation, follow c-at factory torque standards to avoid loose or damaged interfaces.
After installation, start the engine and idle for 5-10 minutes, check for fuel leakage and abnormal operation.
