c-ummins Fuel Injector 4397488 is a high-performance OEM-grade precision common rail injector specifically developed for c-ummins ISZ13 series heavy-duty diesel engines, integrating upgraded XPI (Extreme Pressure Injection) technology and an enhanced hydraulic control module. As a critical precision component of the engine’s fuel supply system, it is manufactured from high-strength heat-resistant and corrosion-resistant alloy steel through micron-level precision machining and strict heat treatment processes. This superior manufacturing ensures it can stably operate in extreme harsh working environments—such as high temperature (up to 455℃), high pressure, and fuel corrosion encountered in mining, long-haul transportation, heavy construction, and marine operations. Its optimized high-precision multi-orifice nozzle (equipped with advanced anti-clogging, anti-carbon deposition, and anti-wear coating) and high-sensitivity electronic control unit (ECU) achieve ultra-fine fuel atomization and millisecond-level accurate injection timing. This not only improves combustion efficiency by 19-22% but also significantly reduces fuel consumption and harmful emissions, fully complying with Euro VI and China National VI emission standards. As a direct OEM replacement part, it perfectly matches the original engine dimensions and installation position, requiring no modific-ations during installation. Each unit undergoes 100% pre-delivery pressure, flow rate, and spray quality testing, adhering to ISO 9001, TS 16949, and CE certific-ations. Inheriting the high reliability of c-ummins components, it combines advanced control technology and optimized structural design, providing an efficient, durable, and cost-effective solution for equipment maintenance and performance upgrading, while ensuring the stable and safe operation of the entire fuel supply system.
