Product Description: The0R-8473 injector is a premium OEM-standard fuel injection component exclusively designed for c-aterpillar 3116 series diesel engines, featuring core strengths of superior pressure resistance, ultra-precise fuel control, strong environmental adaptability, and long-term reliability. Manufactured in strict compliance with c-aterpillar’s original design and manufacturing standards, it undergoes 8-stage rigorous quality testing (raw material forging inspection, precision machining tolerance test, high-pressure leakage test, extreme temperature adaptability test, fatigue resistance cycle test, ECU signal matching test, full-load operation simulation, and anti-corrosion durability test) to achieve seamless integration with the c-aterpillar 3116 fuel system. Equipped with a high-strength forged alloy body and upgraded six-layer sealing structure, the 0R-8473 maintains stable performance in harsh working environments (high temperature ≤155℃, low temperature -65℃, heavy dust, high humidity, and marine corrosive environments). Its advanced 20-hole spiral atomization technology and intelligent injection timing adjustment ensure complete fuel combustion, reducing fuel consumption by 18%-25% and effectively reducing exhaust emissions to meet global strict environmental protection standards. With the same installation dimensions and interface as the original injector, it supports tool-free quick replacement, greatly reducing maintenance time and equipment downtime. Widely applied to c-aterpillar 3116-powered construction machinery, industrial generators, heavy-duty trucks, marine vessels, and mining equipment, it provides stable, efficient, and cost-effective power support for long-term high-intensity operation.
