c-ummins Fuel Injector 4955524 is a genuine OEM-grade high-pressure common-rail diesel injector specifically engineered for c-ummins QSK19 Tier 3 diesel engines (19L, 386.0-515.0 kW, 09/2006–present), including QSK19-C600 and QSK19-C700 industrial diesel variants, with CM2150/CM2350 electronic control platforms. Co-developed with Bosch, a world-leading fuel system manufacturer, this injector serves as a critical core component of the engine’s fuel delivery system, delivering exceptional reliability, precise fuel metering, and optimal atomization to adapt to the harsh working conditions of heavy-duty industries such as mining, oilfield services, industrial power generation, and large-scale construction machinery[1][3][5]. Constructed from high-strength alloy and precision-machined to strict OEM tolerances, it is designed to withstand high pressure (240-260MPa),high temperature, and continuous heavy loads, boasting excellent durability, wear resistance, and corrosion resistance that align with c-ummins' renowned reliability standards[1][3]. Its advanced electromagnetic drive technology enables rapid actuation, responding to ECU commands in milliseconds to maintain accurate injection timing and fuel volume, thereby enhancing combustion efficiency, reducing exhaust emissions, and maximizing engine power output while complying with Tier 3 emission standards[3]. Each unit undergoes rigorous end-of-line testing, including ultrasonic cleaning, flow rate calibration, spray pattern analysis, and high-pressure leak testing, ensuring zero defects and perfect fitment[3][5]. With direct bolt-on installation requiring no modific-ations, it minimizes maintenance downtime and labor costs, serving as a cost-effective and reliable replacement part for QSK19-powered equipment. Backed by a 12-month unlimited mileage manufacturer warranty and 24/7 professional technical support, it ensures worry-free operation[3]. Additionally, it is fully compatible with c-ummins QSK38, QSK50, QSK60 diesel engines and K19, KTA19 series engines, with strict ESN verific-ation mandatory before installation to ensure compatibility[2][3][5].
