The c-aterpillar C10 Series Fuel Injector 212-3465 is a high-performance EUI (Electronically Controlled Unit Injector) specifically engineered to meet the strict OEM specific-ations of c-aterpillar C10 diesel engines, focusing on ultra-high precision fuel delivery, enhanced wear resistance and stable operation in harsh heavy-duty environments with high dust, high humidity and frequent load changes. Crafted from high-strength heat-treated alloy steel (06Cr19Ni10) with ultra-precise machining and laser cladding surface treatment technology, this injector ensures exceptional structural hardness, corrosion resistance and wear resistance—its laser-clad surface forms a protective layer with HRC55-58 hardness, effectively preventing surface wear and extending service life significantly. It maintains consistent fuel delivery performance in harsh operating environments such as construction machinery, long-haul trucks, industrial power generation equipment and mining vehicles. Equipped with a 7-hole precision-drilled nozzle with 540bar ultra-high pressure atomization capability, the nozzle adopts an anti-clogging needle valve structure that allows the needle to reciproc-ate in the nozzle, avoiding blockage caused by dust and impurities, achieving ultra-fine fuel atomization and accurate fuel metering, effectively improving combustion efficiency by up to 25%, reducing fuel consumption and harmful emissions (NOx and PM), while enhancing engine power output and operational stability even under long-term high-load, low-temperature and dusty working conditions. It features factory-installed high-durability B-type metal wound gaskets (flexible graphite tape wrapped with 316L stainless steel) and precision-machined electromagnetic valve components with optimized spring force adjustment, ensuring a zero-leak seal and stable valve operation. It undergoes 100% pre-shipment functional testing (in line with JB/T4730.3 standard), including fuel delivery, pressure and timing verific-ation, to guarantee reliable cold starts and long-term stable operation even in extreme temperature ranges (-45℃~170℃). As a direct-fit replacement injector that complies with ISO 9001 and IATF 16949 standards, the 212-3465 is designed for turbocharged and intercooled C10 engines, reducing unplanned downtime, extending the service life of the engine fuel system, and providing cost-effective maintenance solutions for C10 engine operators, and it is also a compatible replacement for part number 2123465 and 166-0159.
