The 4954374 fuel injector is a high-precision electronically controlled common rail component specifically developed for c-ummins QSK60 series diesel engines, with full compatibility with QSK45 engines and seamless interchangeability with OEM part numbers 4954374, 4326784, 4088428, 4326782, 4088416, 4326779, fully adhering to c-ummins’ strict quality standards and technical specific-ations for high-pressure common rail systems. As a direct OEM replacement part, it perfectly matches the QSK60’s 60.2L displacement and 1715-2240kW (2300-3000hp) power range, integrating smoothly with the engine’s high-pressure common rail fuel system (MCRS) and V-type 16-cylinder layout. Notably, it is a replaceable part for the old part number 4954374, widely used in QSK60-DM marine calibration models and various heavy-duty non-highway scenarios. Capable of withstanding the fuel system’s high-pressure requirement of up to 1800 bar (26108 psi), it ensures stable and efficient fuel delivery even under long-term full-load operation in harsh heavy-duty scenarios, such as large mining trucks, marine main and auxiliary engines, large industrial generator sets, offshore oilfield equipment, and construction machinery like digger excavators. Functioning as a high-precision electronically controlled solenoid valve, 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 even in complex environments like dusty mining sites, marine navigation, offshore operations, and high-intensity industrial work. It boasts high-pressure fuel delivery up to 1800 bar, combined with ultra-fine atomization via precision-machined spray holes and a 2μm plunger clearance, cooperating with the QSK60’s 16-cylinder design to ensure uniform fuel-air mixing. This not only reduces exhaust emissions to meet US EPA Tier 3, EU Stage IIIA, and IMO Tier II-III 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 seawater, and high-pressure impact, ensuring stable injection performance even in harsh working conditions with fuel impurities or extreme temperature fluctuations. Constructed with premium heavy-duty materials through strict screening, including high-strength gray cast iron (HT280) 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, with a weight of 1.3KG as a standard specific-ation. It is compatible with C3 electronic control (CM2150) systems, meets strict installation precision requirements, and professional installation using c-ummins INSITE diagnostic tools is recommended to ensure perfect fit with the QSK60 cylinder head, accurate injection timing calibration, and seamless communic-ation with the engine control system. Every unit undergoes rigorous factory testing, including pressure calibration, flow measurement, spray pattern validation, and leakage checks, and has obtained ISO/CE certific-ation, to ensure full compatibility with c-ummins QSK60 and QSK45 engine control systems and direct replacement for original parts. With a comprehensive set of OEM cross reference numbers, it offers ready-to-ship inventory, customizable neutral or brand packaging options, a 12-month warranty, and reliable after-sales support, with delivery available within 3-7 working days, making it the ideal choice for maintaining the performance, efficiency, and longevity of c-ummins QSK60 series engines in various demanding industrial, mining, marine, power generation, and construction machinery scenarios.
