Cummins Injector QSK23 Series (Part Number: 4087888) Product Details

The Cummins 4087888 fuel injector is a premium OEM-grade common rail injector exclusively engineered for the Cummins QSK23 heavy-duty diesel engine, with extended compatibility to Cummins QSK19G and QSK60 engines[3]. As a critical core component of the diesel fuel injection system, it is precision-manufactured to atomize diesel fuel into fine, uniform droplets and deliver it accurately into the combustion chamber, ensuring complete combustion, stable power output, and reduced exhaust emissions[4]. Widely applied in heavy-duty scenarios such as mining trucks, construction machinery, oilfield drilling rigs, industrial generator sets, and marine equipment, this injector is characterized by superior interchangeability, exceptional high-pressure resistance, rugged durability, and precise fuel metering. Manufactured in strict compliance with ISO 9001 quality management systems and Cummins original technical standards[4], it adopts hardened stainless steel and advanced nickel alloy materials[4], paired with precision CNC machining and laser drilling technologies[4], equipping a high-sensitivity electromagnetic control valve to achieve accurate fuel delivery, enhance fuel economy, and ensure stable operation even in harsh working conditions with high temperature, heavy vibration, and dust. It supports direct bolt-on installation without any modific-ations to the engine or fuel system, effectively reducing maintenance time and operational costs. Each 4087888 injector undergoes 100% pre-delivery quality testing, including high-pressure leakage detection, atomization performance verific-ation, electromagnetic response speed testing, and long-term durability assessment, ensuring consistent performance in extreme environments. The verified OEM Cross-Reference Numbers for 4087888 are 4087888, 4928347[3], which are fully interchangeable with the original QSK23 fuel system, ensuring convenient replacement and wide applicability. The product is a cross-border export-specialized supply[3], available in global stock with fast international shipping (5 workdays)[1], backed by a 1-2 year warranty[1], and factory-direct supply, providing cost-effective and reliable support for the maintenance and efficient operation of QSK23 series engines.
