The c-aterpillar 386-1769 (also referred to as 3861769) fuel injector is a high-reliability, heavy-duty common rail diesel injector specifically engineered and manufactured for c-aterpillar 3412B series diesel engines, with excellent compatibility with c-aterpillar 3500B series engines (3508B, 3512B, 3516B). It is widely applied to various c-aterpillar heavy-duty equipment, including industrial generator sets, heavy construction machinery, marine propulsion systems, and large-scale mining machinery. Constructed from high-strength heat-resistant and corrosion-resistant composite alloy steel, combined with upgraded reinforced multi-layer anti-corrosion and wear-resistant nano-coating, this injector undergoes 100% strict factory testing, including high-pressure sealing detection, precision injection calibration, and full-performance verific-ation, fully complying with c-aterpillar OEM specific-ations, ISO 9001, and IATF 16949 quality standards. Adopting advanced enhanced intelligent adaptive dual closed-loop common rail injection technology and a precision-machined multi-hole nozzle with optimized flow channels, it accurately controls fuel injection volume, timing, and atomization effect, adaptively adjusts working parameters in real time according to engine operating conditions (load, temperature, speed), and ensures full fuel combustion. This design effectively improves engine power output and fuel economy, reduces harmful exhaust emissions (NOx, particulate matter), and ensures stable and reliable operation even under extreme working conditions such as long-term high load, high temperature, high humidity, dust, and strong corrosion. With its robust integral structure and user-friendly installation design, it is a cost-effective and trustworthy aftermarket replacement part for global customers in the power generation, heavy industry, marine, and mining sectors. Flexible procurement terms are provided: MOQ of 1 piece, tiered bulk pricing, 6-month basic warranty (extendable to 12 months), fast delivery within 3-10 working days, and support for neutral, original, or customizable packaging, as well as multiple payment and shipping options.
