The c-aterpillar OR-3051 (also referred to as OR3051) fuel injector is a high-reliability, precision common rail diesel injector exclusively engineered for c-aterpillar 3412A series diesel engines, boasting excellent compatibility with c-aterpillar 3500A series engines (3508, 3512, 3516) and a wide range of c-aterpillar heavy-duty equipment, including generator sets, industrial machinery, marine propulsion systems, and mining loaders[1][3][6]. Crafted from high-strength corrosion-resistant and wear-resistant alloy steel[2][7], this injector undergoes 100% strict factory testing, including high-pressure sealing detection, intelligent precision calibration, and performance verific-ation, fully complying with OEM specific-ations, ISO 9001, and IATF 16949 quality standards[1][6]. It adopts advanced precision pressure-controlled common rail injection technology and a precision-machined multi-hole nozzle, achieving ultra-precise control of fuel injection volume, timing, and atomization effect. This optimization not only enhances the engine’s power output and fuel combustion efficiency but also reduces fuel consumption and harmful exhaust emissions, ensuring stable and reliable operation even under extreme working conditions such as high load, high temperature, high humidity, and dusty environments. With its robust integral structure and specialized anti-corrosion, anti-wear surface treatment, it demonstrates strong adaptability to harsh working environments like dusty mining sites, humid marine cabins, and high-temperature industrial workshops. As a cost-effective and trustworthy replacement part, 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]. It fully meets the maintenance and procurement needs of global customers in the power generation, industrial, marine, and mining sectors, with multiple payment methods (T/T, Western Union, PayPal[6]) and shipping options (express, air, sea[2]) available to facilitate seamless global cooperation.
