New Cummins EPA Tier 3 Marine Diesels

Cummins brings its U.S. EPA Tier 3 certified new QSK19 & QSK60 marine diesel engines to market.

Cummins Tier 3 solutions apply advanced combustion technology to reduce emissions in-cylinder without the need for aftertreatment. The company predict that these engines will serve as the platform for future, more stringent emissions in the U.S. 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. “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 January 1, 2012 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 January 1, 2013.
