Quantum System Electronic Product Line

The Quantum Series product line was introduced in 2005 to meet the U.S. Environmental Protection Agency’s stringent Tier 2 emission standard. Today the product line is certified to EPA Tier 2, IMO Tier II and EU Stage IIIa standards and will serve as the platform for future more stringent standards.

QSK19/38/50/60 engines utilize Cummins’ exclusive Modular Common Rail fuel system (MCRS), a design that allows for multiple injection events to precisely control the combustion process. QSK engines use advanced in-cylinder combustion technology to meet global emissions requirements without increasing displacement or making significant changes to the engine footprint, mounting orientation, ratings and optional equipment from the KV engines, reducing impact to installation.

Proven Quantum System electronics and enhanced engine protection ensure that the engines operate at peak performance. C Command instrument panels include a selection of monitoring and display options that help optimize performance by providing diagnostic and prognostic capabilities and monitoring critical operating parameters such as engine load, duty cycle, speed and fuel consumption.
