Primary Equipment Applications

The QSM11 engine platform is engineered for three core markets, with specialized configurations for each:

  1. Marine Propulsion & Auxiliary Power

    • Applications: Commercial workboats, recreational yachts, fishing vessels, and auxiliary generator sets.

    • Key Features: Proven acceleration and high torque for planing hulls; quiet, virtually smoke-free operation; and marine-grade corrosion-resistant components. Optional SmartCraft® digital integration is available.

  2. Construction & Heavy Engineering Machinery

    • Applications: A flagship engine for demanding off-road equipment such as rotary drilling rigs, truck cranes, mining trucks, wheel loaders, and port forklifts.

    • Key Features: Outstanding reliability and fuel economy for harsh job sites, with power output tailored from 290 to over 400 horsepower for various machine classes.

  3. Industrial Power Generation

    • Applications: Prime and standby diesel generator sets for data centers, industrial plants, commercial facilities, and critical infrastructure.

    • Key Features: Simplified integration with common generator controllers, excellent transient response for load acceptance, and compliance with global emissions standards for stationary power.

Core Technologies & Advantages

The QSM11's superior performance is built on several key technological pillars:

  • Advanced Fuel System: Utilizing the Cummins Celect electronic unit injection system, it ensures extremely precise fuel control and injection timing. This optimizes combustion to deliver maximum power, superior fuel economy, and low emissions.

  • Robust & Serviceable Design: As a heavy-duty four-stroke engine with four valves per cylinder, it is built for longevity. Key features like replaceable wet cylinder liners facilitate maintenance and reduce total life-cycle costs.

  • Intelligent Electronic Control: The full-authority Engine Control Module (ECM) provides precise management of all engine functions, enabling features like programmable power modes, comprehensive diagnostics, and system protection.

  • Integrated Global Support: The engine is backed by Cummins' worldwide service network, the Captain's Briefing for marine users, and a commitment to providing genuine parts and technical expertise wherever it operates.
