There is no substitute for power when your equipment needs it. That’s why Cummins QSL offers ratings from 280-365 hp (209-272 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 to increase power and reduce emissions. At the same time, the QSL delivers better cold starting and runs 50% quieter for increased operator comfort. Every day. QSL engines currently meet Tier 3/Stage IIIA emissions standards with an in-cylinder solution that doesn’t require complex add-ons. The advanced QSL engine platform will be carried forward with the addition of aftertreatment to meet Tier 4/Stage IV emissions through 2011 and beyond.
