The c-aterpillar 20R-1267 (also referred to as 20R1267) fuel injector is a high-efficiency intelligent heavy-duty common rail diesel injector specially developed and manufactured for c-aterpillar 3412B series diesel engines, boasting excellent compatibility with c-aterpillar 3500B series engines (3508B, 3512B, 3516B) and a wide range of c-aterpillar heavy-duty equipment, including industrial generator sets, heavy construction machinery, marine propulsion systems, and large-scale mining machinery[1][3][6]. Crafted from high-strength high-temperature resistant composite alloy steel, supplemented by super anti-corrosion and wear-resistant nano-ceramic coating multi-layer anti-oxidation and anti-corrosion surface treatment[2][7], this injector has passed 100% strict 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[1][6]. It adopts high-efficiency intelligent dual closed-loop common rail injection technology and a precision-machined multi-hole nozzle with optimized flow channels, which can achieve ultra-precise control of fuel injection volume, timing, and atomization effect. This optimization not only maximizes the engine’s power output and fuel combustion efficiency but also effectively reduces fuel consumption and harmful exhaust emissions, ensuring 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. It offers flexible procurement terms: MOQ of 1 piece[2][6], tiered bulk pricing, 6-month basic warranty (extendable to 12 months[1][6]), fast delivery within 3-10 working days, and supports neutral, original, or customizable packaging[2]. Multiple payment methods (T/T, Western Union, PayPal[6]) and shipping options (express, air, sea[2]) are available to facilitate seamless global cooperation and meet diverse maintenance and procurement needs.
