Posted - Wednesday, August 24, 2011 - Maritime Executive

Cummins Inc. (NYSE: CMI), a leading manufacturer of diesel engines for the commercial marine industry, is pleased to announce its U.S. EPA Tier 3 marine product solutions. Improving on the existing EPA Tier 2-certified product line, the company is developing a full range of Tier 3 products from 6.7 to 60 liters and 150 to 2700 HP. Cummins Tier 3 solutions apply advanced combustion technology to reduce emissions in-cylinder without the need for after-treatment. Cummins Tier 3 marine product line will serve as the platform for future, more stringent emissions in the U.S. and globally.
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 takes 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, QSK38 and QSK50 are not required to meet EPA Tier 3 until January 1, 2013.
