ISM11
Cummins
The Cummins ISM11 is a globally recognized, 10.8-liter, all-electronic heavy-duty diesel engine, renowned for setting the benchmark in reliability, performance, and fuel efficiency. As the flagship power of the Cummins M-series, it delivers exceptional power ranging from 308 to 440 horsepower (230 to 328 kW), engineered to excel in the most demanding heavy-duty transportation and vocational applications worldwide. With a global population exceeding 500,000 units and a proven average overhaul interval of over 1 million kilometers, the ISM11 is built to maximize uptime and deliver the lowest total cost of ownership.
The table below summarizes the core specifications of the ISM11 engine series:
The ISM11 is a versatile power source designed for a wide spectrum of heavy-duty equipment:
Heavy-Duty Trucks: The ideal engine for tractors, dump trucks, and freight trucks, providing robust power for long-haul and regional transportation.
Vocational & Special Vehicles: Widely used in cement mixer trucks, tankers, and crane trucks, where durability and high torque are critical.
Buses & Coaches: A trusted powerplant for long-distance coaches and city buses, offering smooth operation and fuel economy.
Other Applications: Also suitable for fire and emergency apparatus, power generation sets, and industrial machinery.
Integrated, Modular Design for Maximum Reliability: The ISM11 integrates five key Cummins subsystems—air handling, fuel, electronic control, filtration, and aftertreatment—into a highly modular design. This approach reduces the total number of parts by approximately 30%, significantly lowering potential failure rates and simplifying maintenance for superior uptime.
Advanced Electronic Control & Celect Fuel System: The engine features a full-authority electronic control module (ECM) that manages over 100 intelligent functions, including cruise control, road speed governing, and proactive diagnostics. Paired with the high-pressure Celect fuel system, it ensures precise fuel injection and metering for optimal combustion, leading to outstanding fuel economy and performance.
Proven Durability for Longevity: Engineered for a 1-million-kilometer overhaul life, the ISM11 incorporates heavy-duty components like a forged steel crankshaft, articulated pistons, and a mid-stop design cylinder liner to minimize oil consumption and withstand extreme operating conditions.
Global Validation and Support: As a mainstay in North American heavy-duty trucks and a key power for leading Chinese OEMs, the ISM11 has accumulated over 300 billion kilometers of real-world operation. It is backed by Cummins' global service network, ensuring comprehensive parts availability and technical support worldwide.
