Tvornička CUMMINS QSK23 4928348 4928348 4954374 4954374 HPI mlaznica za gorivo za QSK60 QSK45 motor Industrijski generatorski set Brodski dijelovi Originalna nova brizgaljka

4928348 mlaznica za gorivo vrhunska je OEM{1}}komponenta common rail-a posebno projektirana za dizelske motore serije c-ummins QSK23, u potpunosti u skladu sa strogim standardima kvalitete c-ummins i tehničkim specifičnostima-[superscript:2], i dizajnirana kao izravni zamjenski dio koji savršeno odgovara QSK23 Zapremina 23,2 L i raspon snage od 760-950 KS. Kao ključna komponenta QSK23 QSK23 sustava visoko{20}}ubrizgavanja pod visokim tlakom (HPI) [superscript:2], integrira naprednu elektroničku kontrolnu tehnologiju s poboljšanim performansama brtvljenja, savršeno se prilagođava kompresijskom omjeru motora od 16,0:1 i brzini praznog hoda od 700 ± 25 o/min [superscript:2], dok odgovara zahtjevima tlaka sustava goriva motora kako bi se osiguralo stabilna i učinkovita isporuka goriva. Posebno optimiziran za teške-scenarije rada, uključujući teške-građevinske strojeve, industrijske generatore, opremu za naftna polja i-strojeve za rudarstvo na velikim-nadmorskim visinama[superscript:3], gdje su dugoročna-trajnost, pouzdano brtvljenje i stabilne performanse pod visokim-tlakom i ekstremnim temperaturnim uvjetima najvažniji. Ova mlaznica funkcionira kao visoko{28}}precizni normalno zatvoreni ventil koji se otvara točno nakon primanja signala iz ECU-a motora, osiguravajući preciznu isporuku goriva i optimalnu učinkovitost izgaranja čak i u složenim radnim okruženjima kao što su visoko{29}}tlačne operacije na moru, prašnjava gradilišta i-visoka rudarska područja. Sadrži isporuku goriva pod visokim-tlakom do 1800 bara (26108 psi), u kombinaciji s ultra-finom atomizacijom (Manje od ili jednako 30 mikrona) putem precizno-strojno obrađenih otvora za raspršivanje, u suradnji s QSK23 dizajnom glave cilindra s četiri-ventila[superscript:1] kako bi se osigurala jednolika miješanje goriva-zraka, smanjujući emisije ispušnih plinova kako bi se zadovoljili standardi US EPA Tier II i EU Stage IIIA, istovremeno poboljšavajući ekonomičnost goriva za 9-13% u usporedbi s konvencionalnim mlaznicama. Opremljen solenoidom ultrabrzog odziva (vrijeme otvaranja/zatvaranja<0.1ms) with 28-32 ohms resistance[superscript:2], it enables precise multi-stage injection (pre-injection, main injection, post-injection) to optimize combustion, minimize engine noise and vibration, and significantly extend the engine's service life. Its enhanced sealing design, featuring four Viton fluoroelastomer O-rings[superscript:2], effectively separates oil and fuel, prevents leakage, and adapts to the engine's fuel return system requirements, ensuring stable performance even under high fuel pressure. Constructed with premium wear-resistant materials through strict screening, including heat-treated high-strength alloy steel for the body (consistent with c-ummins high-precision material standards[superscript:3]), stainless steel nozzle tip with tungsten carbide coating (HRC72) for enhanced durability and corrosion resistance, high-temperature resistant copper solenoid coil, and precision-ground anti-wear alloy plunger, this injector boasts excellent adaptability to extreme temperatures (-40°C to 170°C) and harsh working conditions. It meets strict installation precision requirements, with a recommended torque value of 32 N·m (24 ft-lb) during installation[superscript:2], and four optional thicknesses of seal rings to adjust the injector protrusion, ensuring perfect fit with the cylinder head after cylinder head machining[superscript:2]. Every unit undergoes rigorous factory testing, including pressure calibration, flow measurement, spray pattern validation, and leakage checks, to ensure full compatibility with c-ummins QSK23 engine control systems and direct replacement for original parts. With a comprehensive set of OEM cross reference numbers, it offers ready-to-ship inventory with 3-7 days delivery, hassle-free installation (professional installation is recommended), and reliable after-sales support, including a 12-month warranty and global service network coverage, making it the ideal choice for maintaining the performance, efficiency, and longevity of c-ummins QSK23 series engines in demanding industrial, offshore, and mining scenarios.
