The new Tier 3 and Stage IIIA compliant Cummins QSL engines take you to a whole new level of power, versatility and emissions control. They achieve Tier 3 and Stage IIIA compliance with in-cylinder technology that maintains a compact, simple and cost-effective solution.

There is no substitute for power when your equipment needs it. Every hour of every day, Cummins QSL engines deliver performance that meets the challenge of a multitude of tough industrial applications worldwide. With ratings from 250-365 hp (186-272 kW) and a torque rise of up to 50%, QSL engines combine advanced in-cylinder combustion technology and a High-Pressure Common-Rail (HPCR) fuel system that increases power and reduces emissions. At the same time, the QSL delivers better cold starting and runs 50% quieter for increased operator comfort. Every day.

The advanced design of the QSL ensures that maintenance is kept to an absolute minimum.
