Power： 205 - 305 hp </br> Torque： 675 - 1020 lb-ft </br> Certification： Tier 3 / Stage IIIA,EPA Tier 3,EU Stage III

The QSC meets Tier 3 and Stage IIIA emissions standards, by using in-cylinder technology, a simple and cost-effective solution that maintains the proven performance, dependability and durability of the QSC while operating cleanly and efficiently.

Cummins QSC engines are built on one of the world's most successful - and durable - engine block designs. In fact, there are over three quarters of a million in use around the globe every day.

The QSC advanced electronics provide enhanced engine performance with higher torque and better throttle response at every rpm. Electronic engine control provides additional advantages that include increased fuel economy, precision diagnostics and engine protection. The QSC also offers enhanced maintenance intervals, improved cold starting plus up to 50% quieter operation for improved operator comfort.

Available in a range of ratings from 205-305 hp (153-227 kW), the QSC meets every Tier 3 and Stage IIIA emissions standard without compromise.

The QSC offers a wide range of standard features. And options like REPTO (Rear Engine Power Take-Off) add broad functionality.

To ensure that every QSC is perfectly matched to every piece of equipment, Cummins PowerMatch and Advisor are ready to provide expert assistance with your spec'ing and installation process.

Every QSC engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest plans in the industry.

Features & Benefits

Standard features of the QSC include:

Full-Authority Electronic Controls - Provide seamless integration with other components to optimize engine operation.
Stiffer Block and Head - For reduced noise and vibration. Fluid circuits are integrated, replacing hoses and eliminating potential leaks.
High-Pressure Common-Rail Fuel System - Allows multiple injection events for cleaner, quieter operation with consistent performance at every rpm. Also improves cold-weather starting.
Wastegated Turbocharger - Delivers maximum power and torque.
Mid-Stop Cylinder Liners - Reduce cavitation and improve rebuildability.
Auto-Tensioning Belt Drive - Self adjusting for optimum tension, which increases fan, alternator and fan belt life.
Heavy-Duty Roller Followers - Cam roller followers give the QSC superior durability and cam life.
Two-Stage Dual Fuel Filtration - Provides a balanced level of particle separation to maximize fuel filter life and protect the vital fuel system components.
Gear Housing Design and Front-End Support - The gear housing and accessories mount directly to the block for improved durability.
Improved Piston Design - Symmetrical piston bowl combines with centered injectors to deliver optimal combustion.
Heavy-Duty Lube System - Targeted piston cooling and increased lube flow to the power cylinder result in increased piston reliability and durability. Improved lube and bypass filtration system increase ring and bearing life by as much as 63%.
Improved Crankcase Ventilation - Virtually eliminates oil carryover.
Valve Cover and Gasket - Isolated design with perimeter bolting for better sealing and improved reliability.
