Cummins Injector QSK23 Series (Part Number: 4062090) Product Details

The Cummins 4062090 fuel injector is a premium OEM-grade common rail injector exclusively engineered for the Cummins QSK23 heavy-duty diesel engine, featuring full compatibility with all QSK23 engine configurations and close interchangeability with core QSK23 variants. As a key component of the diesel fuel supply system, it operates as a precision solenoid valve that opens and closes to control fuel injection, ensuring optimal atomization for complete combustion[1]. Widely applied in heavy-duty scenarios including mining machinery, oilfield drilling equipment, industrial generator sets, large-scale construction vehicles, and marine propulsion systems, this injector stands out with its superior precision fuel metering, enhanced sealing performance, excellent high-temperature resistance, and seamless OEM interchangeability. Produced in strict compliance with ISO 9001 quality management system and Cummins original technical standards, it adopts high-strength forged alloy steel and micron-level precision CNC machining[7], combined with a high-sensitivity electromagnetic control valve to achieve accurate fuel delivery, reduce fuel consumption, and meet environmental regulations[1]. It supports direct bolt-on installation without any modific-ations to the engine or fuel system, effectively reducing maintenance time and operational costs. Each 4062090 injector undergoes 100% pre-delivery quality inspection, including high-pressure leakage testing, atomization performance verific-ation, electromagnetic response speed testing, and long-term durability assessment, ensuring consistent and reliable performance in extreme working environments with high temperature, heavy vibration, and dust. The verified OEM Cross-Reference Numbers for 4062090 are 4062090, 4077076, 4902827, 4010577, 3347937, which are fully interchangeable with the original QSK23 fuel system[3], ensuring convenient replacement and wide applicability. The product is available in global stock with fast international shipping, backed by a 6-12 month warranty and factory-direct supply, providing cost-effective and reliable support for the maintenance and efficient operation of QSK23 series engines.
