CUMMINS Factory Dongfeng 4307475 4307468 5491515 Injector de combustible compatible amb peces de motor ISG12 Injector nou original

The 4307468 fuel injector is a high-precision electronically controlled common rail component specifically developed for Dongfeng c-ummins series diesel engines, featuring full compatibility with Foton ISG engines and Dongfeng c-ummins core models such as ISBe3.9L, ISBe4.5L, ISDe4.5L and 6CT8.3—key models in Dongfeng c-ummins' medium-duty and heavy-duty diesel engine lineup. It offers seamless interchangeability with OEM cross reference numbers 4307468, 5491515, 4307475, 4307414, 4384165, fully complying with Dongfeng c-ummins' strict quality standards and technical specific-ations for high-pressure common rail systems, which are renowned for their precision, durability and strong adaptability to commercial vehicle working conditions. As a direct OEM replacement part, it perfectly matches the displacement range and power output of Dongfeng c-ummins and Foton ISG engines, integrating smoothly with the engine's high-pressure common rail fuel system and electronic control systems, making it a dependable replacement for Dongfeng c-ummins and Foton ISG engine fuel injectors. This injector is a crucial component for engine performance, widely applied in various working scenarios such as Dongfeng commercial vehicles, Foton trucks, heavy-duty construction machinery, industrial equipment, and light-duty mining machinery—typical applic-ation fields of Dongfeng c-ummins and Foton ISG engines. Functioning as a high-precision electronically controlled solenoid valve, it operates as a normally closed valve—remaining closed without control signals and opening when the ECU sends an injection command, ensuring precise fuel delivery. Capable of withstanding the fuel system's high-pressure requirement of up to 1800 bar, it ensures stable and efficient fuel delivery even under long-term full-load operation in harsh environments with dust, high humidity, or extreme temperature fluctuations. It responds accurately to signals from the engine's ECU (Electronic Control Unit) with an ultra-fast response time of <0.1ms, ensuring precise fuel metering (with an error of no more than ±2%) and optimal combustion efficiency, which is critical for meeting strict emission standards. This level of precision is achieved through micron-level manufacturing, with a 2μm plunger clearance—equivalent to 1/50 of a human hair—and precision-machined spray holes for ultra-fine atomization, cooperating with the engine's cylinder design to ensure uniform fuel-air mixing. This not only reduces exhaust emissions to meet relevant environmental standards but also improves fuel economy and reduces engine noise and vibration. Equipped with advanced multi-stage injection technology (pre-injection, main injection, post-injection), it optimizes the combustion process, enhances idle stability, and significantly extends the engine's service life. Its enhanced anti-wear and corrosion-resistant design, featuring a precision-ground high-speed steel plunger and hardened stainless steel nozzle tip, effectively resists abrasion, corrosion from harsh fuels, and high-pressure impact, adhering to Dongfeng c-ummins' strict production standards for reliable performance and longer service life. Constructed with premium heavy-duty steel through strict screening, including high-strength steel for the body, high-temperature resistant copper solenoid coil, and high-seal O-rings for effective oil-fuel separation and leakage prevention, this injector boasts excellent adaptability to extreme temperatures (-40°C to 180°C) and harsh working conditions. Every unit undergoes rigorous factory testing, including pressure calibration, flow measurement, spray pattern validation, and leakage checks, and has obtained relevant certific-ations such as ISO 9001 and CE, ensuring reliable performance and consistent quality. With a comprehensive set of OEM cross reference numbers, it offers ready-to-ship inventory, customizable neutral packaging options, a 3-6 month warranty, and reliable after-sales support, with delivery available within 15 working days for small orders via DHL, FedEx, TNT or UPS, making it the ideal choice for maintaining the performance, efficiency, and longevity of Dongfeng c-ummins and Foton ISG engines in various demanding commercial, industrial, and construction scenarios.
