Product Description: Cummins QSX15 Heavy-Duty Diesel Engine

Revolutionizing Heavy-Duty Power Generation and Industrial Applications

The Cummins QSX15 is a groundbreaking heavy-duty diesel engine designed to set new standards for power density, reliability, and operational cost in demanding environments. As the first heavy-duty diesel engine to feature a 24-valve dual overhead camshaft design, the QSX15 delivers uncompromising performance for power generation (G-Drive) and rugged industrial machinery. Its integrated design, which utilizes approximately 30% fewer parts than comparable engines, eliminates external fluid lines for enhanced durability and simplified maintenance, ensuring maximum uptime and a lower total cost of ownership.

Primary Equipment Applications

The QSX15 is ideally suited for both open and enclosed applications in static or portable equipment, serving as a robust power source for:

  • Power Generation (G-Drive): Prime, standby, and continuous power for data centers, commercial facilities, and industrial plants.

  • Mining & Heavy Industry: Crushing plants, drilling rigs, and other high-load equipment.

  • Oil & Gas Operations: Providing reliable power for exploration, production, and pipeline operations.

  • Specialized Mobile Power: Rail applications, intermodal power, movie site production, lighting towers, and welding operations.

  • Construction & Heavy Equipment: Powers large excavators, loaders, and off-highway trucks requiring high torque and durability.

Core Technologies & Features

  1. 24-Valve Dual Overhead Camshaft Design: This pioneering technology allows for superior air intake and exhaust flow, enabling increased power output and faster engine response across the entire RPM range for optimal performance.

  2. Integrated Block Design: The engine's revolutionary integrated fluid circuits replace traditional external hoses, tubing, and connectors. This design drastically reduces potential leak points, improves reliability, and lowers lifecycle maintenance costs.

  3. High-Pressure Fuel Injection System: Capable of injection pressures exceeding 1,900 bar (28,000 psi), this system ensures exceptionally clean and efficient combustion. This translates to superior fuel economy, lower emissions, and consistent power delivery.

  4. Coolpac Integrated Design: Available as a complete power package, the QSX15 can be supplied with an integrated cooling system and air cleaner kit. Each component is specifically engineered and tested for G-Drive products, guaranteeing high performance and durability.

  5. Global Service & Support: Backed by Cummins' world-class service network and industry-leading technical support, ensuring access to parts, expertise, and warranty services globally for maximum equipment uptime.
