The c-aterpillar 20R-1283 (also referred to as 20R1283) fuel injector is an ultra-premium, high-performance intelligent enhanced heavy-duty common rail diesel injector, exclusively engineered and produced for c-aterpillar 3412B series diesel engines. It features exceptional compatibility with c-aterpillar 3500B series engines (3508B, 3512B, 3516B) and is widely applicable to various c-aterpillar heavy-duty equipment, including industrial generator sets, heavy construction machinery, marine propulsion systems, and large-scale mining machinery. Manufactured from ultra-high-strength heat-resistant and corrosion-resistant composite alloy steel, combined with ultimate-grade anti-corrosion and wear-resistant nano-ceramic coating multi-layer anti-oxidation and anti-corrosion surface treatment, this injector undergoes 100% rigorous factory testing—including high-pressure sealing detection, intelligent precision calibration, and full-performance verific-ation—fully complying with c-aterpillar OEM specific-ations, ISO 9001, and IATF 16949 quality standards. It adopts intelligent adaptive enhanced Pro Ultra Max dual closed-loop common rail injection technology and a precision-machined multi-hole nozzle with optimized flow channels, enabling ultra-precise control of fuel injection volume, timing, and atomization effect, while adaptively adjusting working parameters in real time based on engine operating conditions (load, temperature, speed). This optimization maximizes engine power output and fuel combustion efficiency, further reduces fuel consumption and 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 serves as 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 offered: 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. Multiple payment methods (T/T, Western Union, PayPal) and shipping options (express, air, sea) are available to facilitate seamless global cooperation and meet diverse maintenance and procurement needs.
