Cummins Inc. has launched its US EPA Tier 3 certified QSK19 and QSK60 marine engines.
Cummins Tier 3 solutions apply advanced combustion technology to reduce emissions in-cylinder without the need for after treatment.
“We are excited to be actively quoting and selling QSK19 and QSK60 EPA Tier
3 marine products into a variety of applications across the United States,” said Scott Rath, North America Marine sales manager. “With minimal changes to engine architecture, integrating the Tier 3 products into existing vessel designs is not difficult. Customers will continue to see world-class reliability, durability and performance from the next generation Quantum Series engines.”
Representing a 50% reduction in particulate matter (PM) and a 20% reduction in nitrogen oxides (NOx) compared to Tier 2 standards, the EPA’s Tier 3 marine emissions regulation went into effect on 1 January 2012 for Cummins engines between 3.5 and 7.0l per cylinder and continues through 2014.
The Tier 3-certified QSK19 and QSK60 feature the same engine hardware and footprint as the existing MCRS product. Further, the lubrication, cooling, air handling, fuel and exhaust systems are the same design as the current product ensuring minimum disruption for series-built vessels or replacement engines. As with Tier 2, Tier 3 engines will be available with Cummins C Command panels, CENTINEL Oil Management System and the ELIMINATOR filter to help monitor and reduce the cost of operation and maintenance.
The QSK19, with Tier 3 ratings from 660 to 750hp, and the QSK60, with ratings between 2000 and 2700hp, are suited to high-hour demanding applications including fishing, offshore support, towing, cargo and passenger transport, as well as ship’s service power and diesel electric applications.
Cummins launched its full Tier 3 product line from 6.7 to 60l at the International Workboat Show in New Orleans in December 2012.
