Cummins Introduces the QSK60 Tier 2 Marine Engine
Cummins Inc. has upgraded the QSK60 marine engine for propulsion and auxiliary applications to meet U.S. EPA Tier 2 and European Union Stage IIIA emissions regulations. With propulsion ratings from 1492 - 1864 kW and auxiliary ratings from 1563 - 1900 kW, the QSK60 Tier 2 is ideally suited for high-hour demanding applications such as offshore support, towing, cargo and passenger transport.
Early in the product design phase, Cummins consulted with the International Association of Classification Societies (IACS) to ensure the engine meets agency requirements and is fully SOLAS compliant. The QSK60 will be built and marinized at Cummins Engine Co., Ltd in Daventry, UK.
The 60 liter, V-16 engine utilizes the Cummins Modular Common Rail fuel system (MCRS), a design that allows for multiple injection events to precisely control the combustion process. The MCRS provides constant high injection pressure regardless of engine speed or load conditions, which improves idle stability while reducing engine noise and vibration for quiet operation.
Cummins has utilized an advanced in-cylinder solution to meet Tier 2 and Stage IIIA emissions standards without increasing displacement or making significant configuration changes, thus reducing the impact to installation.
