Cummins
Proven Power and Reliability for Heavy-Duty Applications
The Cummins M11 is a robust and versatile inline-six diesel engine renowned for its durability, fuel efficiency, and strong performance across demanding on- and off-highway applications. As a reliable workhorse, it delivers dependable power for heavy-duty trucks, construction equipment, and specialized vocational vehicles. Its evolution incorporated advanced electronic controls while maintaining the mechanical simplicity prized by operators and fleet managers worldwide.
The following table summarizes the key specifications of the M11 engine platform:
The versatility of the M11 engine makes it suitable for a broad range of heavy-duty machinery:
On-Highway Trucks: Ideal for heavy-duty tractors, dump trucks, and mixer trucks, providing reliable power for regional haulage and vocational duties.
Construction & Mining Equipment: A trusted power source for loaders, excavators, bulldozers, cranes, and compactors in rugged environments.
Specialized Vehicles: Commonly used in fire and emergency apparatus, refuse trucks, and agricultural tractors.
Stationary Power: Suitable for industrial air compressors and generator sets.
Patented PT & Advanced CELECT™ Plus Fuel Systems: The engine features the mechanically robust Cummins PT (Pressure-Time) fuel system, known for high injection pressure, excellent reliability, and ease of maintenance. Later models are equipped with the CELECT™ Plus full-authority electronic fuel system, which optimizes injection timing and metering for superior fuel economy, performance, and precise control.
Optimized Combustion and Air Handling: Incorporating a Holset turbocharger and charge-air cooling maximizes air intake efficiency, improving power density and fuel economy. The four-valve-per-cylinder head design optimizes the air-fuel mixture for cleaner and more efficient combustion.
Durable Engine Architecture: Built for longevity with a high-strength alloy cast iron cylinder block, forged steel crankshaft, and replaceable wet cylinder liners for superior heat dissipation and serviceability. The articulated piston design ensures durability under high thermal and mechanical loads.
User-Oriented Design for Low Operation Cost: Engineered for easy maintenance with features like centralized filter locations. Its reputation for high reliability and fuel efficiency translates into a low total cost of ownership for fleets. The platform also offers uprateability, allowing for rating flexibility to adapt to changing business needs.
