CUMMINS Factory Dongfeng gravemaskine dele brændstofinjektor 5263308 4307468 4988835 4915382 4307475 til ISG12 ISF2.8 ISF3.8 QSL8.9 QSC8.3 dieselmotor original ny injektor

Brændstofinjektoren 4307475 er en høj-elektronisk styret common rail-komponent, der er specielt udviklet til Dongfeng c-ummins-seriens dieselmotorer, med fuld kompatibilitet med Foton ISG-motorer (især ISG 12-serien) og Dongfeng c-modeller, såsom IS,4Be-9.L.5,4L. ISDe4.5L og 6CT8.3 – nøglemodeller i Dongfeng c-ummins' medium-udvalgte og tunge-dieselmotorer. Det tilbyder problemfri udskiftelighed med OEM krydsreferencenumre 4307475, 5491515, 4307468, 0445110429, 17093E011, der fuldt ud overholder Dongfeng c-ummins' strenge kvalitetsstandarder og tekniske specifikationer for{}høje{21}systemer, som er almindelige{21} kendt for deres præcision, holdbarhed og stærke tilpasningsevne til erhvervskøretøjer og tekniske maskiners arbejdsforhold. Som en direkte OEM-udskiftningsdel matcher den perfekt slagvolumen og udgangseffekten af ​​Dongfeng c-ummins og Foton ISG-motorer, og integreres problemfrit med motorens-højtryks common rail-brændstofsystem og elektroniske styresystemer, hvilket gør den til en pålidelig erstatning for Dongfeng c-iSG-motorer i Fotonfeng c-ummins. Denne injektor er en afgørende komponent for motorens ydeevne, og den anvendes i vid udstrækning i forskellige arbejdsscenarier såsom Dongfeng-erhvervskøretøjer, Foton Auman-lastbiler, larvebåndsgravemaskiner, tunge-entreprenørmaskiner, industrielt udstyr og dieselgeneratorer – typiske{29}}anvendelsesområder for Dongfeng c-motorer og Foton ISG-motorer. Den fungerer som en høj-elektronisk styret magnetventil og fungerer som en normalt lukket ventil – forbliver lukket uden kontrolsignaler og åbner, når ECU'en sender en indsprøjtningskommando, hvilket sikrer præcis brændstoftilførsel. Den er i stand til at modstå brændstofsystemets høje-trykkrav på op til 1800 bar og sikrer stabil og effektiv brændstoflevering selv under lang-fuld-drift i barske miljøer med støv, høj luftfugtighed eller ekstreme temperaturudsving. Den reagerer præcist på signaler fra motorens ECU (Electronic Control Unit) med en ultra-hurtig responstid på<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 such as Euro V. 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 cast steel and high-speed 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, CE, TS 16949 and ROHS, ensuring reliable performance and consistent quality. With a comprehensive set of OEM cross reference numbers, it offers ready-to-ship inventory, customizable neutral packaging (carton or wooden case) options, a 3-6 month warranty, and reliable after-sales support, with delivery available within 5-7 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.
