New Tier 2 Marine Engine From Cummins

Posted on December 2, 2008

Cummins Inc. has upgraded the QSK60 marine engine for propulsion and auxiliary applications to meet U.S. EPA Tier 2 and European Union Stage 3A emissions regulations. With propulsion ratings from 2100 to 2500 bhp and auxiliary ratings from 2095 to 2547 bhp, the QSK60 Tier 2 is targeted toward high-hour applications such as offshore support, towing, cargo and passenger transport, as well as ship’s service power.

The 60 L, 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 and provides constant high injection pressure regardless of engine speed or load conditions, Cummins said. The engine also utilizes an advanced in-cylinder solution to meet Tier 2 and Stage 3A emissions standards without increasing displacement or making significant configuration changes, thus reducing the impact to installation, the company said.
