QSK23-C760
Cummins
Unmatched Power and Endurance for the World's Toughest Jobs
Engineered for relentless performance in the most demanding environments, the Cummins QSK23-C760 is a heavy-duty industrial powerhouse. This 23-liter, inline-six diesel engine delivers a robust 760 HP (567 kW) and massive low-speed torque, providing the dependable, high-density power needed to maximize productivity in mining, construction, and energy sectors. Built on a legacy of Cummins durability, it is designed for extended service life and superior uptime, ensuring the lowest total cost of ownership for your critical operations.
The QSK23-C760 is engineered to be the prime mover for high-load, continuous-duty equipment across several heavy industries:
Mining & Heavy Construction: Provides reliable power for large off-highway haul trucks, mining excavators, wheel loaders, and drill rigs, where its high torque and durability are essential for 24/7 operations .
Oil & Gas Well Servicing: A proven and dependable choice for well stimulation (frac) pumps, cementing units, and drilling rigs, delivering the consistent power needed for demanding wellsite operations .
Heavy-Duty Power Generation: Serves as a robust prime mover for large industrial and mining generator sets, ensuring reliable standby and prime power .
Other Industrial: Powers high-capacity industrial pumps, compressors, and specialized marine equipment.
High-Pressure Injection (HPI) Fuel System: The engine utilizes the advanced Cummins HPI Celect fuel system, capable of injection pressures up to 29,000 psi . This enables extremely precise fuel delivery and more complete combustion, resulting in superior engine response, best-in-class fuel economy, and lower emissions .
Robust Heavy-Duty Architecture for Long Life: Designed for million-mile reliability, the QSK23 shares the proven power cylinder design of larger Cummins engines . Key features include:
One-Piece Cast Iron Block: Provides exceptional strength and excellent rebuild capability .
Forged Steel Crankshaft & Ferrous Cast Ductile Iron (FCD) Pistons: Engineered to withstand extreme mechanical and thermal loads, ensuring durability and consistent performance over multiple overhaul cycles .
Seven-Bolt Cylinder Head: Delivers increased clamping force to handle high cylinder pressures, contributing to long-term sealing and reliability .
Full-Authority Intelligent Electronic Controls: The sophisticated electronic control module (ECM) optimizes engine performance in real-time based on load, altitude, and fuel quality. It provides advanced diagnostics, monitoring, and integrated engine protection features, maximizing uptime and simplifying maintenance .
Optimized for Serviceability and Uptime: The design prioritizes ease of maintenance with features like a rear gear train for reduced noise and more precise timing . Its legendary durability is demonstrated by data showing a significant portion of engines achieving over 800,000 kilometers without major overhaul .
