Product Description: The 0R-8475 injector is a high-end OEM-standard fuel injection component exclusively developed for c-aterpillar 3116 series diesel engines, boasting core features of ultra-high pressure resistance, precise fuel metering, enhanced anti-corrosion performance, and long-term stable operation. Produced in strict accordance with c-aterpillar’s original technical specific-ations and undergoing 9-stage rigorous quality testing (raw material purity inspection, forging precision test, high-pressure sealing test, extreme temperature cycle test, fatigue resistance test, ECU signal compatibility test, full-load operation verific-ation, anti-corrosion durability test, and long-term service simulation), it achieves seamless integration with the c-aterpillar 3116 fuel system. Equipped with a reinforced high-strength forged alloy body and upgraded seven-layer sealing structure, the 0R-8475 maintains stable performance in extreme harsh working environments (high temperature ≤160℃, low temperature -70℃, heavy dust, high humidity, marine corrosive environments, and mining harsh conditions). Its advanced 22-hole spiral atomization technology and intelligent adaptive injection timing adjustment ensure more thorough fuel combustion, reducing fuel consumption by 20%-26% and effectively lowering exhaust emissions to meet the most stringent global 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 used in c-aterpillar 3116-powered construction machinery, industrial generators, heavy-duty trucks, marine vessels, and mining equipment, it provides reliable, efficient, and cost-effective power support for long-term high-intensity operation.
