Cummins QSK19 and QSK60 EPA Tier 3 certified marine engines now available

Cummins Inc., the Charleston, S.C.-based manufacturer of diesel engines for the commercial marine industry, announces the availability of its U.S. 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 aftertreatment, the company says. Cummins’ Tier 3 marine product line will serve as the platform for future, more stringent emissions in the United States and globally.

“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,” says Scott Rath, North America Marine Sales Manager, in a Cummins press release. “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 percent reduction in particulate matter and a 20 percent reduction in nitrogen oxides compared to Tier 2 standards, the EPA’s Tier 3 marine emissions regulation went into effect Jan. 1 for Cummins engines between 3.5 and 7.0 liters per cylinder and continues through 2014. The QSK60 is the only engine in Cummins marine portfolio requiring EPA Tier 3 certification in 2012; the QSK19 is not required to meet EPA Tier 3 until Jan. 1, 2013.

The Tier 3-certified QSK19 and QSK60 feature the same premium base engine hardware and footprint as the existing MCRS product, Cummins says. Further, the lubrication, cooling, air handling, fuel and exhaust systems are the same design as the current product, the company says, 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 750 hp, and the QSK60, with ratings between 2,000 and 2,700 hp, are ideally suited for high-hour demanding applications including offshore support, towing, cargo and passenger transport, as well as ship’s service power and diesel electric applications, Cummins says. Cummins Quantum Series MCRS auxiliary engines were specifically designed for light load operation, while also being capable of providing full power to meet the variable power demands of diesel electric applications. Cummins says the QSK engines’ Modular Common Rail fuel system featuring closed nozzle injectors and electronic control system allow for speed stability at all load and speed conditions.

The QSK19 and QSK60 Tier 3-certified engines are covered by a comprehensive one-year warranty, valid at authorized Cummins service outlets worldwide. In addition, the engine is backed by Cummins Mobile QuickServe program. Cummins QuickServe offers factory-certified technicians, the most sophisticated diagnostic and repair tools in the industry and the largest international parts and service network of any engine manufacturer, the company says.

Cummins will launch its full Tier 3 product line from 6.7 to 60 liters at the International Workboat Show in New Orleans, Wednesday, Dec. 5 through Friday, Dec. 7.
