The 4954801 fuel injector is a high-performance electronically controlled common rail component specifically designed for c-ummins QSK60 series diesel engines, with full compatibility with QSK45 and QSK23 engines. It features seamless interchangeability with OEM cross reference numbers 4954801, 4954374, 4326784, 4088428, 4326782, 4955527, fully complying with 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. This injector is widely applied in extreme heavy-duty scenarios, especially suitable for QSK60 C3 electronic control platform (Tier3/4 emission) models, which are commonly used in large mining trucks (such as Terex and c-aterpillar), oilfield fracturing trucks, large industrial generator sets, marine main and auxiliary engines, and mining excavator supporting power systems. 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 environments with dust, high humidity, or extreme temperature fluctuations. 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. 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. 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 1.35KG 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. Every unit undergoes rigorous factory testing, including pressure calibration, flow measurement, spray pattern validation, and leakage checks, and has obtained ISO/CE certific-ation. 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.
