Product Description: The 0R-8461 injector is a high-performance, OEM-standard fuel injection component exclusively designed for c-aterpillar 3116 series diesel engines, boasting core advantages of enhanced wear resistance, precise fuel atomization, strong anti-interference ability, and long service life. Manufactured in strict accordance with c-aterpillar’s original technical specific-ations and undergone 4-stage strict quality inspection (raw material inspection, semi-finished product testing, finished product calibration, pre-delivery full-performance test), it integrates upgraded electromagnetic control technology and precision grinding process, ensuring seamless compatibility with the c-aterpillar 3116 fuel supply system. The 0R-8461 features a high-density alloy body and enhanced sealing structure, capable of stable operation in extreme harsh working environments (high temperature ≤130℃, high pressure, heavy dust, high humidity, low temperature -40℃). Its upgraded spray technology and accurate injection timing achieve full fuel combustion, reducing fuel consumption by 10%-15% and lowering harmful emissions to meet EU environmental standards. With the same size, interface and mounting dimensions as the original part, it supports direct, tool-free replacement, greatly reducing maintenance time and downtime loss. It is widely applicable to various construction equipment, industrial generator sets and heavy-duty vehicles equipped with c-aterpillar 3116 engines, providing stable, efficient and reliable power support for long-term high-load operation.
