Product Core Features

Feature c-ategory	Detailed Description	User Benefits
High-Pressure Precision Performance	Adopts advanced high-pressure fuel atomization technology, with precise fuel delivery control and ultra-fine uniform atomization, ensuring full combustion of fuel in the engine cylinder, adapting to the high-power demand of 3116 series engines .	Significantly improves engine power output and torque, reduces fuel consumption by 5%-8%, lowers exhaust emissions, and meets international environmental protection standards.
Super Durable Quality	The injector body is made of high-strength heat-resistant alloy material, with multi-layer hard coating treatment, which can resist high temperature, high pressure, excessive wear and dirty fuel erosion, effectively extending the service life by 30% compared with ordinary injectors .	Greatly reduces the frequency of replacement and maintenance, saves equipment operation costs, and ensures long-term stable operation of the engine under heavy-load and harsh working conditions.
Perfect Compatibility	Strictly manufactured according to c-aterpillar OEM standards, fully matching the 3116 series high-power engines, no need to modify the installation position, direct bolt-on replacement, consistent with the original part size and interface .	Simplifies replacement process, saves maintenance time and labor costs, avoids installation errors, and ensures the normal operation of the engine after replacement.
Stable & Reliable Operation	Optimized internal structure design, strong anti-interference ability, stable fuel injection pressure, no oil leakage, jamming and other failures under high temperature, high pressure and harsh working environments, with strong adaptability.	Reduces equipment downtime caused by injector failure, improves work efficiency, and is suitable for long-term heavy-load operation scenarios such as mining, construction and engineering.
Easy Maintenance & Inspection	The structure is simple and easy to disassemble, daily inspection and maintenance can be completed without professional tools, and the atomization effect can be quickly checked, reducing maintenance difficulty and cost.	Low maintenance threshold, convenient for on-site maintenance, further reducing the overall operation cost of the equipment, and ensuring the continuous and stable operation of the equipment.

Replacement & Maintenance Tips

Operation Type	Detailed Tips
Replacement Note	1. Before replacement, turn off the engine and cut off the fuel supply to avoid fuel leakage; 2. It is recommended to replace the entire set of fuel injectors to ensure the optimal performance of the high-power engine ; 3. After installation, check for fuel leakage and start the engine to test the operation status, and adjust the fuel injection pressure if necessary.
Daily Maintenance	1. Regularly check the injector for oil leakage, blockage and other phenomena; 2. Use qualified high-quality fuel to avoid impurity accumulation affecting atomization effect and damaging the injector; 3. Clean the injector every 2000 working hours to extend its service life.
Fault Judgment	If the engine has insufficient power, increased fuel consumption, unstable idling, black smoke or abnormal noise, it may be caused by injector failure, and it is recommended to check and replace the injector in time to avoid further damage to the engine.

FAQ (Frequently Asked Questions)

Question	Answer
Is 0R-8479 compatible with c-aterpillar 3126 high-power engine?	Yes, this injector is fully compatible with c-aterpillar 3114, 3116 and 3126 high-power engines, and can be directly replaced without modific-ation, perfectly matching the engine's power demand .
What is the difference between 0R-8479 and ordinary 3116 injector?	0R-8479 is designed for high-power versions of 3116 series engines, with higher injection pressure, better atomization effect and more wear-resistant material.
