Product Description: The 0R-8463 injector is an OEM-standard, high-reliability fuel injection component specially developed for c-aterpillar 3116 series diesel engines, featuring core strengths of superior pressure resistance, ultra-precise fuel control, enhanced environmental adaptability, and extended service life. Produced in strict compliance with c-aterpillar’s original design standards and passing 4-stage strict quality inspection (raw material screening, precision machining testing, performance calibration, pre-delivery full-load operation test), it adopts advanced electromagnetic control technology and integrated forging process, ensuring perfect matching with the c-aterpillar 3116 fuel system. The 0R-8463 is equipped with a reinforced alloy body and a dual-sealing structure, which can operate stably in extreme harsh working conditions (high temperature ≤135℃, high pressure, heavy dust, high humidity, low temperature -45℃). Its upgraded multi-hole spray technology and accurate injection timing realize full combustion of fuel, reducing fuel consumption by 12%-18% and reducing harmful emissions to meet the latest EU environmental protection standards. With the same size, interface and installation dimensions as the original part, it supports direct tool-free replacement, which greatly shortens maintenance time and reduces equipment downtime loss. It is widely used in various construction machinery, industrial generator sets and heavy-duty vehicles equipped with c-aterpillar 3116 engines, providing stable, efficient and durable power support for long-term high-load and continuous operation.
