c-ummins Fuel Injector ISZ13 Series 4326989 Product Description

Product Overview

c-ummins Fuel Injector 4326989 is a high-performance OEM-grade enhanced common rail injector specially designed for c-ummins ISZ13 series heavy-duty diesel engines, integrating upgraded XPI (Extreme Pressure Injection) technology and a high-stability reinforced hydraulic control system. As a core precision component of the engine’s fuel supply system, it is elaborately manufactured from high-strength heat-resistant and corrosion-resistant alloy steel through micron-level precision machining and strict heat treatment processes. This advanced production ensures it can stably withstand extreme high temperatures (up to 445℃), high pressure, and fuel corrosion in harsh working environments such as mining, long-haul transportation, heavy construction, and marine operations. Its optimized high-precision multi-orifice nozzle (with enhanced anti-clogging, anti-carbon deposition and anti-wear design) and high-sensitivity electronic control unit (ECU) achieve ultra-fine fuel atomization and millisecond-level accurate injection timing, which not only improves combustion efficiency by 17-20% 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 integrates advanced control technology and optimized structural design, providing a more efficient, durable, and cost-effective solution for equipment maintenance and performance upgrading, while ensuring the stable and reliable operation of the entire fuel supply system.
