Cummins Injector QSK23 Series (Part Number: 4087886) Product Details

The Cummins 4087886 fuel injector is a high-performance OEM-grade common rail injector specially designed for the Cummins QSK23 heavy-duty diesel engine, with extended compatibility to Cummins QSK19 engines[2][5]. As a vital 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[2][6]. Widely used in heavy-duty applic-ations such as construction machinery, mining equipment, oilfield drilling rigs, industrial generator sets, and heavy-duty trucks, this injector is featured with excellent interchangeability, reliable high-pressure resistance, rugged durability, and precise fuel metering. Manufactured in strict compliance with ISO 9001, IATF 16949 quality management systems and Cummins original technical standards[3], it adopts high-strength alloy steel and advanced precision CNC machining technology[2][6], paired with a high-sensitivity electromagnetic control valve to achieve accurate fuel delivery, enhance fuel economy, and ensure stable operation even in harsh working conditions. It supports direct bolt-on installation without any modific-ations to the engine or fuel system, effectively reducing maintenance time and operational costs. Each 4087886 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 with high temperature, heavy vibration, and dust. The verified OEM Cross-Reference Numbers for 4087886 are 4087886, 4001830, 4010029, 4928345[2][4][6], which are fully interchangeable with the original QSK23 fuel system, ensuring convenient replacement and wide applicability. The product is available in global stock with fast international shipping (1-2 workdays)[2], 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.
