CUMMINS Factory QSK23 High Quality Diesel Fuel Injector Valves 4954892 4902828 4902827 4088431 For Cu Mmins QSK23 M11 Diesel Engine Parts Original New Injector

The 4088431 fuel injector is a high-performance OEM-grade common rail component specifically engineered for c-ummins QSK23 series diesel engines, fully compliant with c-ummins strict quality standards and specific-ations[superscript:1], and designed as a direct replacement part to perfectly match the QSK23’s 23L displacement and 760-969 HP power range[superscript:4]. As a core component of the high-pressure injection (HPI) system of QSK23 engines, it is tailored for diverse harsh heavy-duty applic-ations including mining machinery, large-scale construction equipment, industrial generator sets, commercial trucks, and marine engines[superscript:1][superscript:2], where long-term reliability, stable performance and high fuel efficiency are critical. This injector adopts advanced electronic control technology, integrated with an intelligent ECU communic-ation module, ensuring precise fuel metering and optimal combustion efficiency even in complex working conditions. It features high-pressure fuel delivery up to 1800 bar (26108 psi), combined with ultra-fine atomization (≤34 microns) leveraging precision-machined spray holes to guarantee uniform fuel distribution, effectively reducing exhaust emissions to meet US EPA Tier II and EU Stage IIIA standards, while improving fuel economy by 7-10% compared to conventional injectors[superscript:5]. Equipped with an ultra-fast responding solenoid (opening/closing time <0.1ms), it enables precise multi-stage injection (pre-injection, main injection, post-injection) to optimize combustion efficiency, minimize engine noise and vibration, and extend the engine’s service life significantly. Constructed with premium wear-resistant materials selected through strict screening[superscript:1], including heat-treated high-strength alloy steel for the body, stainless steel nozzle tip with tungsten carbide coating (HRC72) for enhanced durability and corrosion resistance, high-temperature resistant copper solenoid coil, and Viton fluoroelastomer seals to ensure effective oil-fuel separation and prevent leakage, this injector boasts excellent adaptability to extreme temperatures (-40°C to 170°C) and harsh working environments such as high humidity marine scenarios. Every unit undergoes strict factory testing, including pressure calibration, flow measurement, spray pattern validation, and leakage checks[superscript:1], to ensure perfect 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 hassle-free installation (professional installation is recommended for marine and heavy-duty applic-ations) and reliable after-sales support, including a 12-month warranty[superscript:1] 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 and marine scenarios.
