Cummins Conjunto de motor desnudo QSX15 bloque de motor para maquinaria de construcción

The Cummins QSX15 series is a premier power platform for industrial and heavy-duty machinery. While sharing the same lineage as the on-highway ISX15 version, it has been specifically reinforced for off-highway industrial operating conditions. It is renowned for its massive power reserve, exceptional transient response, and extreme reliability in harsh environments. Its "bare engine assembly" comprises core components such as the cast-iron cylinder block, cylinder head assembly, crankshaft, connecting rods, pistons, and camshaft.

Engine Configuration: Inline-6 ​​cylinder, 4-stroke, 15-liter (912 cu in) displacement

Cooling System: High-efficiency, heavy-duty liquid cooling system

Rated Power: Approximately 300 – 522 kW (400 – 700 hp), with specific power ratings tailored to industrial applications (e.g., mining equipment, large industrial pumps, or crushers)

Fuel System: Cummins High-Pressure Common Rail (HPCR) system, delivering ultra-high injection pressure to optimize combustion efficiency and reduce emissions

Key Advantages:

Ultimate Power: Delivers sustained, stable high-torque output and excellent load response for heavy-duty industrial operations.

Industrial-Grade Reinforcement: Structurally reinforced to withstand the shock loads typical of off-highway operations, ensuring an exceptionally long service life.

Global Service Support: As a core Cummins model, it benefits from readily available spare parts worldwide and mature technical support.

Primary Applications: Mining excavators, heavy-duty bulldozers, large-scale stone crushing equipment, stationary/mobile industrial power generation units, and deep-water drilling power systems.
