PRODUCT Detail
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.
Performance
Cummins QSL engines are built to deliver heavy-duty performance in every piece of machinery. Full-authority electronic engine controls combine with the High-Pressure Common-Rail fuel system for strong performance at every rpm. Its free-breathing 24-valve design and centered injectors give the QSL one of the highest power-to-weight ratios in its class. Plus, the QSL is capable of running on high-sulfur fuels, so it’s at home in every corner of the globe.
