Product Description: The 0R-8471 injector is a high-performance, OEM-compliant fuel injection component specifically engineered for c-aterpillar 3116 series diesel engines, boasting core advantages of enhanced atomization efficiency, extended service life, strong anti-jamming capability, and cost-effective operation. Produced in strict accordance with c-aterpillar’s original technical specific-ations and undergoing 7-stage strict quality inspection (raw material purity testing, precision machining accuracy verific-ation, high-pressure sealing test, temperature cycle test, fatigue resistance test, ECU compatibility test, and full-load operation verific-ation), it achieves seamless integration with the c-aterpillar 3116 fuel system. Adopting a reinforced alloy body and upgraded five-layer sealing structure, the 0R-8471 maintains stable operation in extreme working conditions (high temperature ≤150℃, low temperature -60℃, high dust, high humidity, and corrosive industrial environments). Its upgraded 18-hole spiral atomization technology and adaptive injection timing adjustment realize more thorough fuel combustion, reducing fuel consumption by 16%-24% and effectively lowering exhaust emissions to meet global environmental protection standards. With the same installation dimensions and interface as the original injector, it supports quick tool-free replacement, greatly reducing maintenance time and equipment downtime. Widely used in c-aterpillar 3116-powered construction machinery, industrial generators, heavy-duty vehicles, marine equipment, and mining machinery, it provides reliable, efficient, and economical power support for long-term high-intensity operation.
