CUMMINS Factory QSL 2897414 4327072 4821827 4928421 Injektor goriva za ISL9.5 ISC8.3 dizelski motor QSL Injektor Tovornjak Avtodeli Originalni nov injektor

Injektor goriva 4821827 je visoko{1}}natančna elektronsko krmiljena komponenta skupnega voda, posebej izdelana za dizelske motorje serije c-ummins QSL, s popolno združljivostjo z motorji QSC8.3, QSL9, QSL9.3, ISL9.5 in 6C8.3 – osnovni modeli v c-srednji{10}}obremenitvi ponudba dizelskih motorjev. Odlikuje ga brezhibna zamenljivost z navzkrižnimi referenčnimi številkami proizvajalcev originalne opreme 4821827, 2897414, 4928421, 4327072, 4307452, 2872069, ki v celoti upošteva c-umminsove stroge standarde kakovosti in tehnične specifikacije-za visokotlačni skupni vod- sistemi[2]. Kot neposredni nadomestni del OEM se popolnoma ujema z obsegom prostornine in izhodno močjo serije QSL ter se gladko integrira z visokotlačnim-sistemom goriva s skupnim vodom motorja in elektronskimi krmilnimi sistemi CM2250, CM2350, zaradi česar je zanesljiva zamenjava za c-ummins QSL9, QSL9.3 in QSC8.3 injektorje goriva motorja. Ta injektor je ključna komponenta za srednje{31}}zmogljivost motorja, ki se široko uporablja v različnih delovnih scenarijih, kot so gospodarska vozila (vključno z Dongfengom), težki-gradbeni stroji, industrijska oprema, lahki-rudniški stroji in dizelski tovornjaki, ki so tipična-polja uporabe QSL, QSC8.3, ISL9.5 in 6C8.3 motorji. Deluje kot visoko{40}}natančen elektronsko krmiljen elektromagnetni ventil in deluje kot normalno zaprt ventil – ostane zaprt brez krmilnih signalov in se odpre, ko ECU pošlje ukaz za vbrizgavanje, kar zagotavlja natančno dovajanje goriva. Zmožen vzdržati visoke-tlačne zahteve sistema za gorivo do 1800 barov, zagotavlja stabilno in učinkovito dobavo goriva tudi pri dolgotrajnem-delovanju s polno-obremenitvijo v težkih okoljih s prahom, visoko vlažnostjo ali ekstremnimi temperaturnimi nihanji. Natančno se odziva na signale iz ECU (elektronske krmilne enote) motorja z ultra-hitrim odzivnim časom<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. It boasts high-pressure fuel delivery up to 1800 bar, combined with ultra-fine atomization via precision-machined 0.12mm spray holes and a 2μm plunger clearance—equivalent to 1/50 of a human hair—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 anti-wear alloy plunger and hardened stainless steel nozzle tip, effectively resists abrasion, corrosion from harsh fuels, and high-pressure impact, adhering to c-ummins' strict production standards for reliable performance and longer service life. Constructed with premium heavy-duty steel and iron 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 5-7 working days via DHL, FedEx, TNT or UPS, making it the ideal choice for maintaining the performance, efficiency, and longevity of c-ummins QSL series engines in various demanding commercial, industrial, and construction scenarios.
