Caterpillar Injector C10 High Quality C10 Diesel Fuel Injector 223-5327 229-5918 233-5327 0R-8773 2235327 2295918 2335327 0R8773 Original New Injector

The c-aterpillar C10 Series Fuel Injector 223-5327 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 high-precision fuel delivery, enhanced structural stability, and reliable operation in harsh heavy-duty environments with high dust, high humidity, frequent load changes and extreme temperature variations. As a critical component of the engine fuel supply system, it executes the final fuel injection "switch" function, receiving pulse signals from the ECU to control fuel injection timing and quantity precisely. Crafted from high-strength heat-treated alloy steel (1Cr18Ni9Ti) with ultra-precise CNC machining and plasma spraying surface treatment technology, this injector ensures exceptional structural rigidity, corrosion resistance and wear resistance—its plasma-sprayed ceramic coating forms a smooth, dense protective layer with HRC59-61 hardness, featuring strong adhesion and excellent high-temperature resistance, effectively preventing surface wear, corrosion and impurity accumulation, and extending service life in harsh operating conditions. 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 580bar ultra-high pressure atomization capability, the nozzle adopts an anti-clogging ball valve structure that boasts automatic centering performance and high sealing performance, allowing smooth reciproc-ation to avoid blockage caused by dust and impurities, achieving ultra-fine fuel atomization and accurate fuel metering, effectively improving combustion efficiency by up to 28%, 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, meeting higher emission standards similar to Euro Ⅳ requirements. It features factory-installed high-durability E-type metal wound gaskets (flexible graphite tape wrapped with 316L stainless steel, Class 1 series) and precision-machined electromagnetic valve components with optimized spring force adjustment, ensuring a zero-leak seal and stable valve operation even under extreme pressure fluctuations, with the gasket meeting high-pressure sealing requirements of turbocharged engines. 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 (-50℃~185℃). As a direct-fit replacement injector that complies with ISO 9001 and IATF 16949 standards, the 223-5327 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 2235327 and 166-0178.
